Is there a pin-compatible replacement for MF0W4FF2201A50?

Yes, parts like Yageo's MFR-25FBF52-2K2 are axial, pin-compatible packages. However, their electrical parameters like TCR differ, so they are not drop-in replacements without engineering review.

What risks should I check before replacing MF0W4FF2201A50?

Key risks include parametric differences. Check if your circuit can tolerate a weaker Temperature Coefficient (TCR), a different resistance value, or a lack of increased power rating margin. The target is also flame retardant, which may be a critical feature.
