Is there a pin-compatible replacement for FRC1210F5R10TS?

Yes, 1210W2F510KT5E is pin-compatible as it uses the same 1210 package. While it is a form-fit match, it is not a guaranteed drop-in replacement without verifying all secondary electrical parameters like TCR.

What risks should I check before replacing FRC1210F5R10TS?

When substituting, check three main things: 1) Resistance value and tolerance, as some alternatives are 4.7Ω or have 5% tolerance. 2) Power rating, ensure 0.5W is sufficient. 3) Temperature Coefficient (TCR), especially in temperature-sensitive circuits.
