Is there a pin-compatible replacement for FRC0402F6651TS?

All listed alternatives use the same 0402 package and are physically pin-compatible. However, none are electrically identical due to different resistance values, so they are not drop-in replacements without engineering review.

What risks should I check before replacing FRC0402F6651TS?

The primary risk is the change in resistance, which can affect circuit timing, gain, or bias points. For precision circuits, also review the Temperature Coefficient of Resistance (TCR) and technology (Thick vs. Thin Film). Always verify the alternative in your specific application.
