Is there a pin-compatible replacement for FRC1210F1200TS?

Yes, several pin-compatible replacements in the 1210 package exist. RS1210K1200FT is an excellent option. Other parts like RC1210JR-07120RL are also pin-compatible but have a looser tolerance that requires review.

What risks should I check before replacing FRC1210F1200TS?

Key risks include using a resistor with a wider tolerance (e.g., ±5% instead of ±1%) or a higher Temperature Coefficient of Resistance (TCR), which can affect circuit precision. Always verify the power rating is equal to or greater than the original part.
