Find and compare replacements for the BHFUSE BSMD1812-075-33V, a 0.75A 33V PTC resettable fuse in an 1812 package. This guide analyzes top alternatives based on critical electrical and physical parameters.

AI replacement insight

Electrical risklow

Low for candidates with matching hold current and voltage. Medium to High if hold current differs.

Package risklow

All reviewed candidates use the same 1812 package, ensuring physical compatibility.

Can it be replaced directly?

Direct replacement for BSMD1812-075-33V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The FUZETEC FSMD075-33R is the most promising alternative due to its matching critical specifications, including hold current, voltage, power, and package.

Main risk

The primary risk when substituting PTC fuses is a mismatch in hold current, which alters the circuit's protection point. Secondary risks include differences in trip time and resistance.
