What risks should I check before replacing SMD0805-035-16V?

Before replacing, verify the candidate's time-current curve to ensure it provides protection at the desired speed. Also check the initial and post-trip resistance values to confirm they are compatible with your circuit's impedance requirements.

SMD0805-035-16V Alternatives, Datasheet & Cross Reference | TECHFUSE

SMD0805-035-16V is a 16V, 0.35A PTC resettable fuse in an 0805 package for overcurrent protection. Strong pin-compatible alternatives with identical or upgraded ratings are available.

AI replacement insight

Electrical risklow

Time-current curves and resistance profiles should be compared, but key ratings match.

Package risklow

All strong candidates use the same standard 0805 package.

Can it be replaced directly?

Direct replacement for SMD0805-035-16V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use BHFUSE BSMD0805-035-16V for a direct match or BSMD0805-035-24V for an upgraded voltage rating.

Main risk

The primary risk is a mismatch in the time-current trip characteristics, which could alter the circuit's protection behavior.

Recommended alternatives

A strong pin-compatible alternative from BHFUSE with matching hold current, trip current, and voltage rating.
