Is there a pin-compatible replacement for BSMD1812-014-60V?

Several parts like TECHFUSE mSMD014 share the same 1812 package and are electrically similar. While form-fit is identical, full pin-to-pin compatibility requires verifying secondary parameters like time-to-trip and max fault current.

What risks should I check before replacing BSMD1812-014-60V?

Key risks include mismatches in max fault current (Imax), trip current (Itrip), and time-to-trip characteristics. Some alternatives have a lower Imax (e.g., 10A vs 40A), which can lead to device failure in high-current fault conditions.
