Is there a pin-compatible replacement for FRC0603F4304TS?

While several 0603 resistors are physically compatible, no direct drop-in replacement with the exact 4.3MΩ resistance has been identified. Alternatives like FRC0603F4704TS have a different resistance value (4.7MΩ) and must be reviewed by an engineer.

What risks should I check before replacing FRC0603F4304TS?

The primary risk is the change in resistance. For example, FRC0603F4704TS has a 4.7MΩ value. This can affect timing, biasing, or feedback loops. Also, check for tolerance downgrades; FRC0603J475 TS has a looser ±5% tolerance, which is unsuitable for precision applications.
