Is there a pin-compatible replacement for MFR-25FBF52-20K?

While several axial resistors match electrically, they often have different body sizes due to higher power ratings. No drop-in pin-compatible replacement is confirmed without verifying physical dimensions against your layout.

What risks should I check before replacing MFR-25FBF52-20K?

The main risks are physical size (package dimensions) and temperature coefficient (TCR). Upgrades often have larger bodies, and some alternatives may have a worse TCR, affecting performance in sensitive circuits.
