AI replacement insight

Electrical riskhigh

Using a part with incorrect hold/trip current negates the circuit protection function.

Package risklow

All candidates use the same 1206 package, but land pattern should be verified.

Can it be replaced directly?

Direct replacement for BSMD1206-150-12V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use BNstar SMD1206-150C-12V for the closest parametric match or TECHFUSE nSMD150-16V for an upgraded voltage rating.

Main risk

Using a part with a higher hold current (e.g., 2.0A) will compromise the intended overcurrent protection.
