Is there a pin-compatible replacement for FRC0402F3601TS?

Yes, all suggested alternatives share the same 0402 package and are pin-compatible from a physical standpoint. However, none are electrically identical due to different nominal resistance values, so they are not drop-in replacements without review.

What risks should I check before replacing FRC0402F3601TS?

The main risk is the difference in resistance. A change from 3.6kΩ to 3.3kΩ, 3.7kΩ, or 3.9kΩ could affect the circuit's timing, biasing, or gain. Always verify the impact of this change in your specific application before committing to a substitute.
