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.

AI replacement insight

Electrical risklow

Candidates have superior voltage ratings and matching hold current. Post-trip resistance is slightly higher.

Package risklow

All parts use the standard 0603 package, ensuring mechanical compatibility.

Can it be replaced directly?

Direct replacement for ASMD0603-010-30V 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 ASMD0603-010-30V, then review parametric alternatives for package and electrical fit.

Main risk

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.
