Is there a pin-compatible replacement for BSMD0805-020-15V?

Several parts like SMD0805-020C-33V share the same 2-pin 0805 package and are likely pin-compatible. However, direct drop-in suitability depends on all electrical parameters and should be confirmed by an engineer.

What risks should I check before replacing BSMD0805-020-15V?

Key risks include differences in voltage rating (Vmax), hold/trip current (Ih/It), time-to-trip characteristics, and initial resistance. Ensure the replacement provides adequate overcurrent protection without affecting normal operation.
