The Bourns MF-USMF010-2 is a 30V, 0.1A hold current PTC resettable fuse in a 1210 package. Strong alternatives exist with matching electricals, but may require checking for AEC-Q200 qualification for automotive use.

AI replacement insight

Electrical risklow

For matched parts, electrical risk is low. High for parts with different current ratings.

Package risklow

All strong candidates use the standard 1210 package.

Sourcing riskmedium

AEC-Q200 qualification may limit the pool of true drop-in replacements.

Can it be replaced directly?

Direct replacement for MF-USMF010-2 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

SMD1210-010-60V offers an upgraded voltage rating, while SMD1210P010TF is a direct match. Both require qualification review.

Main risk

The primary risk is using a part with a different hold current, altering protection. A secondary risk is missing AEC-Q200 qualification.
