Is there a pin-compatible replacement for FRC1206J1R0 TS?

Yes, FRC1206F1R00TS is a pin-compatible replacement. Additionally, SR732BRTTD1R20F is pin-compatible in the same 1206 package but has a slightly different resistance of 1.2Ω that must be verified for your application.

What risks should I check before replacing FRC1206J1R0 TS?

Before replacing, verify the substitute's package is 1206. Check that its resistance, power, and voltage ratings are equal to or better than the original. For parametric alternatives, ensure any deviation (e.g., 1.2Ω vs 1.0Ω) is acceptable for your circuit.
