Choosing the right keycaps for your mechanical keyboard can significantly enhance your typing experience and aesthetic. Two popular compact keyboards, the Apex 9 TKL and the Ducky One 3 Mini, each have different compatibility considerations. This guide will help you understand the keycap compatibility for both models.

Understanding Keycap Sizes and Profiles

Keycaps come in various sizes and profiles. The most common sizes are:

  • OEM: Standard profile, widely used in many keyboards.
  • Cherry: Similar to OEM but slightly shorter.
  • SA: High-profile, sculpted for a vintage feel.
  • XDA: Uniform profile, flat and low.

Most mechanical keyboards, including the Apex 9 TKL and Ducky One 3 Mini, use keycaps compatible with Cherry MX stems, which are the industry standard.

Keycap Compatibility of the Apex 9 TKL

The Apex 9 TKL features a standard ANSI layout with a 75% form factor. It typically uses Cherry MX-compatible stems, making it compatible with most keycap sets designed for Cherry MX switches.

However, some keycaps may not fit perfectly if the set is designed for different switch types or profiles. The Apex 9 TKL supports:

  • Cherry MX stems
  • Gateron, Kailh, and other MX-compatible switches

It is recommended to verify the keycap set specifications to ensure compatibility, especially for non-standard or specialty keycaps.

Keycap Compatibility of the Ducky One 3 Mini

The Ducky One 3 Mini is also a compact 60% keyboard with a standard ANSI layout. It uses Cherry MX-compatible stems, making it compatible with a wide range of keycap sets.

This keyboard supports:

  • Cherry MX stems
  • Gateron, Kailh, and other MX-compatible switches

Because of its standard layout, most keycap sets designed for Cherry MX switches will fit the Ducky One 3 Mini without issues.

Special Considerations

While both keyboards are compatible with Cherry MX-style keycaps, there are some considerations:

  • Keycap Profile: Choose a profile that matches your preference for comfort and aesthetics.
  • Keycap Material: PBT keycaps are durable and resistant to shine, while ABS keycaps are more common and cheaper.
  • Keycap Set Size: Ensure the set includes all necessary key sizes, especially for the function row or additional keys if needed.

Both keyboards support aftermarket keycap sets, but double-check the number of keys and layout compatibility before purchasing.

Conclusion

The Apex 9 TKL and Ducky One 3 Mini are highly compatible with standard Cherry MX keycap sets. When selecting keycaps, consider the profile, material, and layout to ensure a perfect fit and optimal typing experience. Always verify the specifications of your chosen keycap set to avoid compatibility issues.
