Is there a pin-compatible replacement for BSMD0805-025-6V?

Yes, several parts like SMD0805B035TF share the same 2-pin 0805 package. However, their electrical characteristics, specifically hold and trip current, differ and are not a direct match.

What risks should I check before replacing BSMD0805-025-6V?

The primary risk is the change in current protection. Verify the new, higher hold/trip currents are safe for your application. Also check the time-to-trip and resistance characteristics to avoid unexpected behavior.

BSMD0805-025-6V Alternatives, Datasheet & Cross Reference | BHFUSE

Finding a replacement for the BHFUSE BSMD0805-025-6V PTC fuse requires careful matching of hold/trip currents. While several 0805 6V options exist, most have higher current ratings, which requires engineering review.

AI replacement insight

Electrical riskhigh

Higher hold/trip currents change the protection point.

Package risklow

All viable candidates use the same 0805 package.

Sourcing riskmedium

Finding an exact match for 0.25A hold current in 0805/6V is challenging.

Can it be replaced directly?

No direct, drop-in replacement was found. All reviewed candidates have higher hold/trip currents, which alters the circuit's protection level and requires engineering sign-off.

Best replacement path

The best path is to find a PTC fuse with hold current near 0.25A. Candidates like Yageo's SMD0805B035TF are functionally similar but allow more current before tripping.

Main risk

The main risk is using a substitute with a higher hold current, which may not protect the downstream circuit from overcurrent conditions the original part was designed for.

Recommended alternatives

Functional alternative from Yageo in a 0805 package with a 6V rating, but features higher hold and trip currents.
