Is there a pin-compatible replacement for BSMD0805-110-6V?

Yes, several 0805 package PTC fuses are pin-compatible, like SL0805150. However, pin compatibility does not guarantee electrical interchangeability. Always check hold/trip currents.

What risks should I check before replacing BSMD0805-110-6V?

The main risk is using a part with a higher hold current, which may not protect your circuit from overcurrent events the original fuse was designed for. Also verify time-to-trip and resistance characteristics.

BSMD0805-110-6V Alternatives, Datasheet & Cross Reference | BHFUSE

BSMD0805-110-6V is a 6V, 1.1A hold current PTC resettable fuse in a standard 0805 package. Finding a replacement requires matching hold and trip currents closely to ensure proper circuit protection.

AI replacement insight

Electrical riskhigh

Hold current mismatch is critical for PTC fuses.

Package risklow

All viable candidates use the same 0805 package.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found. All viable candidates have a higher hold current, which reduces circuit protection sensitivity.

Best replacement path

The closest option is SL0805150, but it requires engineering review due to its higher 1.5A hold current.

Main risk

Electrical mismatch, specifically a higher hold current, which could lead to circuit damage under fault conditions the original part would have prevented.

Recommended alternatives

A form-fit alternate in an 0805 package with a higher hold current of 1.5A that requires circuit validation.
