Is there a pin-compatible replacement for FRC2512F2403TS?

Yes, several parts like 25121WF2203T4E share the same 2512 package and 2-pin layout, but key electrical parameters like resistance and tolerance may differ.

What risks should I check before replacing FRC2512F2403TS?

Verify that your circuit can tolerate a resistance value different from 240kΩ and check if a wider tolerance (e.g., ±5% vs ±1%) is acceptable for your application.
