Is there a pin-compatible replacement for FRC0603F3004TS?

No, there is no confirmed drop-in replacement. While candidates like RC0603FR-073ML are pin-compatible in the same 0603 package, they have different electrical parameters (like TCR) that must be reviewed.

What risks should I check before replacing FRC0603F3004TS?

Before replacing, verify your application's tolerance for: 1) Temperature Coefficient (TCR), as some alternatives are weaker. 2) Resistance Tolerance, as some are ±5% vs ±1%. 3) Nominal Resistance, as some differ by up to 10%.
