BHFUSE
A pin-compatible PTC fuse in the same 0603 package with a significantly higher voltage rating of 36V.
ASMD0603-010-30V is a 30V, 0.1A PTC resettable fuse in a 0603 package. Several pin-compatible alternatives with higher voltage ratings are available, offering an easy upgrade path for enhanced circuit protection.
Candidates have superior voltage ratings and matching hold current. Post-trip resistance is slightly higher.
All parts use the standard 0603 package, ensuring mechanical compatibility.
Direct replacement for ASMD0603-010-30V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for ASMD0603-010-30V, then review parametric alternatives for package and electrical fit.
The primary risk is a minor difference in post-trip resistance, which could slightly alter circuit recovery time after a fault. This should be verified in the application.
