BSMD0603-010-15V is a common 0603 PTC resettable fuse. Several pin-compatible alternatives with matching or improved electrical ratings are available from manufacturers like RUILON, TECHFUSE, and BNstar.

AI replacement insight

Electrical risklow

Low for parametrically matched parts; medium if trip current differs.

Package risklow

All viable candidates share the same 0603 package.

Sourcing risklow

Multiple vendors offer compatible parts, reducing sourcing dependency.

Can it be replaced directly?

Direct replacement for BSMD0603-010-15V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Upgrade to SMD0603-010C-33V for higher voltage margin or use SMD0603P010TF for a direct parametric match.

Main risk

The main risk is overlooking secondary parameters like trip time or using a part with an incorrect trip current.
