FSMD005-1206-R is a common 60V, 50mA PTC resettable fuse in a 1206 package. Several strong, pin-compatible alternatives are available, offering flexibility in sourcing and design.

AI replacement insight

Electrical risklow

Key static parameters match. Dynamic behavior (trip time) should be verified.

Package risklow

All strong candidates use the same standard 1206 package.

Sourcing risklow

Multiple alternative manufacturers improve supply chain resilience.

Can it be replaced directly?

Direct replacement for FSMD005-1206-R should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for FSMD005-1206-R, then review parametric alternatives for package and electrical fit.

Main risk

Slight variations in dynamic behavior, such as trip time and resistance-temperature characteristics, may exist between manufacturers.
