Is there a pin-compatible replacement for FRC0603F3833TS?

Several parts like FRC0603F3903TS and RC0603FR-07402KL share the same 0603 package and pinout. However, they are not exact drop-in replacements due to different resistance values and require engineering review.

What risks should I check before replacing FRC0603F3833TS?

The main risk is the change in resistance. Ensure your circuit can tolerate the new value (e.g., 390kΩ or 402kΩ instead of 383kΩ). All other key parameters like power, tolerance, and package match.
