Is there a pin-compatible replacement for KH-3216-A35?

Several antennas like AH316M245001-T share the 2-pin 1206 package, making them physically compatible. However, their electrical performance, especially gain, is much lower and requires careful evaluation before use.

What risks should I check before replacing KH-3216-A35?

The main risk is reduced RF performance due to lower gain, affecting signal range and link stability. Also, check the VSWR and ensure the replacement's land pattern and required clearance area match your PCB layout.

Q: What is the best alternative to KH-3216-A35?

Currently, no direct drop-in replacement with matching high gain has been identified. Alternatives like Taiyo Yuden's AH316M245001-T offer a similar package and frequency but have significantly lower gain, which will impact RF performance.

The Kinghelm KH-3216-A35 is a high-gain 2.4GHz ceramic chip antenna. Finding a direct replacement requires matching its 5.19dBi peak gain and 1206 package size, which is challenging.
