Is there a pin-compatible replacement for FRC0603F3741TS?

No direct pin-compatible replacement with the exact 3.74kΩ resistance was identified. However, several parts are available in the same 0603 package with similar electrical characteristics and nearby resistance values, making them potential parametric alternatives.

What risks should I check before replacing FRC0603F3741TS?

Before replacing FRC0603F3741TS, check the impact of the resistance change (typically +/- 2.4%) on your circuit's performance. Also, confirm the 0.1W power rating provides sufficient margin for your design's power dissipation.
