For Keychron PBT keycaps, shortlist PBT-12 Grey/White/Blue if you want the documented Cherry-profile, non-shine-through set. Shortlist the Double-Shot OSA PBT Side-Printed Full Keycap Set if you want side legends with advertised shine-through and your exact ANSI keyboard matches its support list. Both use double-shot PBT and MX-style stems, but those shared specifications do not establish complete keyboard compatibility. Cherry set specifications · OSA side-printed specifications
Here, PBT identifies the material, double-shot identifies the production method, and profile describes keycap shape and row contour. OSA means OEM Spherical Angled. MX style is the listings' cap-stem specification; ANSI and ISO-UK are layout labels. Keep these fields separate when checking a product.

This guide is for owners choosing replacement caps for an existing keyboard. It compares these two exact products and gives you a way to check the remaining fit questions before ordering.
Quick takeaways
- Choose by exact product identity, profile, legend placement, and light transmission.
- Check individual mounting, complete key coverage, and unobstructed travel separately.
- Keep your keyboard's full model, revision, and regional layout attached to every compatibility check.

Use this table to eliminate a set that misses a required feature. For example, a requirement for illuminated legends rules out PBT-12 on its documented specification. A preference for Cherry profile keeps PBT-12 in consideration, subject to the layout and clearance checks below.
Start with material and product identity
Both products meet a request for double-shot PBT. That makes material and production method shared specifications in this comparison; profile, lighting, and documented layout support provide the more useful distinctions. The listed thicknesses describe the products, but they do not establish a measured sound, comfort, or durability advantage. Compare the Cherry specifications and OSA specifications.
When saving a candidate, record its full name, colorway, SKU where available, and selected package. Keep that record beside the keyboard's complete model name and revision. This prevents a specification from one listing from being carried over to a similarly named product during checkout.
Keychron Cherry keycaps: identify PBT-12
The exact Cherry option here is Cherry Profile Double-Shot PBT Full Set Keycaps — Grey, White, and Blue, SKU PBT-12. Its documented specifications are 218 keys, double-shot PBT, 1.5 mm thickness, MX-style stems, and legends that do not transmit backlight. The listing also carries ANSI and ISO-UK layout labels. Official PBT-12 listing
Shortlist it when Cherry profile and non-shine-through legends match your preferences. Keep those specifications tied to PBT-12; do not substitute the specifications or support list of a separate Cherry dye-sub product.
The key count is an inventory total, not a completed fit check. Before buying, compare every required key with the selected package's inventory, including width, row, and regional legend. The available listing excerpt does not establish the individual dimensions needed to approve your particular keyboard.
For an ISO-UK keyboard, the layout label is relevant evidence to investigate further. Ask for the exact selected kit diagram and check the required Enter, Shift, punctuation, bottom-row, and spacebar keys. Leave any unconfirmed size or row assignment marked unknown until the documentation resolves it.
Keychron side-printed keycaps: check the support list
The exact alternative is the Double-Shot OSA PBT Side-Printed Full Keycap Set. Keychron specifies double-shot PBT, 1.6 mm thickness, MX-style stems, OSA profile, backlight shine-through, and ANSI layout. Official side-printed listing Use the KSA and OSA shape comparison to investigate the shape without transferring another OSA set’s specifications.
The captured manufacturer's support list names the following:
| Group | Advertised ANSI support |
|---|---|
| Q families | Q and Q Max series, excluding Q60 and Q60 Max; Q Pro, Q Ultra, and Q HE series |
| V families and 81 Pro | V, V Max, and V Ultra series; 81 Pro |
| K models | K2, K2 Pro, K2 Max; K4, K4 Pro; K6, K6 Pro; K8, K8 Pro, K8 Max; K10, K10 Pro, K10 Max; K12, K12 Pro; K14, K14 Pro |
| C models | C1, C1 Pro, C2, C2 Pro |
| Lemokey models | L1, L3, L4, P1 |
Source: Keychron's side-printed compatibility excerpt, captured October 15, 2026.
Q60 and Q60 Max are explicitly excluded. Preserve those exclusions even though the broader Q families appear in the list. Likewise, retain suffixes such as Pro and Max when checking a named model; do not extend a listed name to an unlisted revision or similarly named variant.
Shortlist this set when you want side legends and advertised shine-through, and your exact ANSI model passes that support check. Before ordering, verify the selected package and the lighting arrangement of your board. The shine-through label does not establish brightness or visibility for every LED position and switch housing.
Understand Cherry, OSA, and LSA profile names
Keychron lists LSA, meaning Low-profile Spherical Angled, separately from OSA, Cherry, KSA, MDA, and OEM. These profile labels organize shape information; they do not identify a retail kit's material, manufacturing method, or included keys. Official profile reference For an LSA candidate, continue with the LSA product and fit guide.
For Cherry specifically, Keychron describes cylindrical tops and sculpted R1–R4 rows with different heights and angles. This makes row assignment a useful inventory check alongside key width and legend. A spare key bearing the desired label still needs the appropriate row shape for its intended position. Official Cherry profile reference
Use the profile references to understand the shape you are selecting. Obtain exact keyboard and kit documentation to settle mounting and clearance; a familiar profile name cannot fill those missing fields.
Check keycaps for Keychron in three stages
Treat compatibility as three separate questions. Complete all three for each keyboard you plan to equip, even if a product has a relevant family name or an MX-style cap specification.
1. Can each required cap mount correctly?
Compare the cap's mounting specification with the exact switch installed in your keyboard. Confirm insertion geometry and, for stabilized keys, the stabilizer type and mounting-point spacing. Both compared sets advertise MX-style cap stems; that wording does not establish the unknown switch and stabilizer details of your board. Cherry mounting specification · OSA mounting specification
Do not extend that wording to low-profile, optical, or magnetic switch interchangeability. Ask for confirmation tied to the exact keyboard revision and switch configuration whenever those details remain unresolved.
2. Does the package cover the complete layout?
Compare the keyboard layout with the selected kit one position at a time. Record the required key width, row, legend, and quantity, then match each against the package inventory. Check stabilized keys, bottom-row modifiers, spacebar size, and regional layout explicitly.
Keep mounting and coverage results separate. A successful check for one ordinary key leaves the rest of the keyboard unapproved. Similarly, the 218-key PBT-12 count and the side-printed set's ANSI support label do not supply the unseen per-key dimensions. PBT-12 inventory label · Side-printed layout specification
3. Is travel unobstructed, and is the lighting suitable?
Confirm clearance throughout key travel against the exact switch housing, LED arrangement, neighboring keys, and case. For side legends, also verify LED orientation and any available confirmation for that board-and-cap combination. Keep physical clearance and desired lighting appearance as separate results.
The available specifications establish non-shine-through legends for PBT-12 and advertised shine-through for the OSA set. They do not establish measured brightness or interference-free operation on your board. Cherry lighting specification · OSA lighting specification
Use a separate worksheet for each model and revision
The example rows below deliberately leave unverified hardware details visible. Replace the example model names with your actual candidates and create a separate row for every revision or regional variant you own. “Unknown” means confirmation is still required.
| Example target | Board stem and insertion geometry | Stabilizer type and spacing | Bottom-row widths and spacebar size | Actual region/layout | Travel clearance and LED orientation |
|---|---|---|---|---|---|
| K2 Pro; revision unknown | Unknown | Unknown | Unknown | Unknown | Unknown |
| K8 Max; revision unknown | Unknown | Unknown | Unknown | Unknown | Unknown |
| Q60; revision unknown | Unknown | Unknown | Unknown | Unknown | Unknown |
| Q60 Max; revision unknown | Unknown | Unknown | Unknown | Unknown | Unknown |
For the side-printed set, K2 Pro and K8 Max appear in the advertised ANSI list; their exact revision, package coverage, and physical checks still need completion. Q60 and Q60 Max fail the advertised support check and should not be selected through that list. None of these rows establishes PBT-12 compatibility. Side-printed support and exclusions
Before you order Keychron replacement keycaps
Use the worksheet to prepare one focused request to the seller or manufacturer:
- Confirm the exact product name, selected variant, SKU where available, and package contents.
- Provide your keyboard's full model, revision, switch configuration, and regional layout.
- Request the kit inventory and confirmation of every unresolved mounting, stabilized-key, bottom-row, and spacebar requirement.
- Ask about full-travel clearance and, for side legends, LED orientation.
- Check the actual seller's current price, stock, delivery, return conditions, and applicable warranty terms.
Keep the reply with the selected product details. If an essential fit question remains unanswered, leave the purchase decision open rather than treating a family name or cap count as confirmation.
Frequently asked questions
Do Keychron keycaps fit every Keychron keyboard?
Compatibility requires the exact set and keyboard combination. The side-printed set advertises ANSI support for named models and excludes Q60 and Q60 Max. Both sets specify MX-style cap stems, but complete layout coverage, stabilized keys, and travel clearance require separate checks. PBT-12 stem specification · OSA stem specification and model support
Is PBT-12 a shine-through set?
PBT-12 Grey/White/Blue is documented as non-shine-through. If illuminated side legends are your priority, investigate the named OSA side-printed set, which advertises backlight shine-through. Its lighting result on a particular keyboard still requires confirmation. PBT-12 specifications · OSA specifications
Does OSA mean the same thing as LSA?
Keychron lists them separately: OSA means OEM Spherical Angled, while LSA means Low-profile Spherical Angled. Use the exact profile name when identifying a product, then verify its retail-kit specifications and keyboard support independently. Keychron profile definitions
Make the final choice
Choose your Keychron PBT keycaps candidate by documented profile, legend placement, and lighting requirements: PBT-12 for the scoped Cherry, non-shine-through option; the named OSA set for side-printed shine-through and matching advertised ANSI support. Complete the model worksheet before ordering either set.
