Is there a pin-compatible replacement for BSMD1210-200-6V?

Yes, several PTC fuses in a 1210 package are pin-compatible, including SL1210210. However, pin compatibility does not guarantee electrical compatibility. Always check key parameters like hold current and max fault current.

What risks should I check before replacing BSMD1210-200-6V?

The main risks are incorrect circuit protection and device failure. Using a part with a higher hold current may not protect your circuit from overcurrent events. Using a part with a lower max fault current could cause the fuse to fail destructively during a short circuit.

BSMD1210-200-6V Alternatives, Datasheet & Cross Reference | BHFUSE

BSMD1210-200-6V is a 6V, 2A PTC resettable fuse in a 1210 package. While no exact drop-in is available, alternatives exist but require careful review of hold current and max fault current ratings to ensure proper circuit protection.

AI replacement insight

Electrical riskmedium

Candidates have different hold current or max fault current ratings.

Package risklow

All viable candidates share the same 1210 package.

Can it be replaced directly?

No exact drop-in replacement was found. SL1210210 is a strong candidate but requires verification of the maximum fault current to ensure system reliability.

Best replacement path

SL1210210 by TECHFUSE is the closest functional match, but its lower max fault current (50A vs 100A) must be acceptable for your design.

Main risk

The primary risk is mismatch in current ratings, either allowing too much current before tripping (higher Ihold) or failing under a high fault current (lower Imax).

Recommended alternatives

Strong functional match with identical package and very similar hold current, but lower max fault current.
