TECHFUSE
A strong pin-compatible alternative from TECHFUSE with identical voltage and hold current; review trip current.
Find and compare suitable replacements for the BHFUSE BSMD0603-005-15V, a 0603 PTC resettable fuse. This guide analyzes pin-compatible alternatives and functional upgrades, highlighting key electrical differences to ensure proper circuit protection.
The best candidates have a slightly higher trip current (200mA vs 150mA), which is a low risk but requires verification.
All candidates share the same 0603 package, ensuring mechanical compatibility.
Direct replacement for BSMD0603-005-15V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SMD0603P005TF and SMD0603-005 are the strongest candidates, matching key specs but requiring review of the slightly higher trip current.
Mismatched trip current may alter circuit protection timing, potentially leaving downstream components vulnerable.
