Is there a pin-compatible replacement for FRC0603F1872TS?

Yes, several pin-compatible 0603 resistors exist, such as FRC0603F1802TS. However, they are not exact functional matches due to different resistance values and should be considered parametric alternatives.

What risks should I check before replacing FRC0603F1872TS?

The main risk is the change in resistance. Verify how a deviation of -3% to -10% affects your circuit's timing, biasing, or feedback loops. Also confirm that power, voltage, and temperature ratings are sufficient.
