Is there a pin-compatible replacement for AC0402FR-0723K2L?

While several parts share the 0402 package, no direct drop-in replacement with the exact 23.2kΩ resistance has been identified. The closest options, like AC0402FR-0724K9L, have different resistance values and require engineering review.

What risks should I check before replacing AC0402FR-0723K2L?

The primary risk is the change in resistance. Even a small change can affect circuit timing, gain, or sensor accuracy. Always verify that the new resistance value is within your circuit's tolerance. Also, ensure the replacement has the required AEC-Q200 qualification for automotive use.
