Is there a pin-compatible replacement for BSMD2920-400-24V?

Yes, several alternatives like BSMD2920-300-33V share the same 2-pin 2920 package. However, their electrical parameters like hold current differ, so they are not drop-in replacements.

What risks should I check before replacing BSMD2920-400-24V?

Verify the hold current (I_hold) and trip current (I_trip). A lower hold current may cause false trips, while a higher one may not adequately protect your circuit. Also confirm the voltage rating is equal or higher.

AI replacement insight

Electrical riskmedium

Hold current differences require circuit analysis.

Package risklow

All viable candidates share the same 2920 package.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have different hold currents, which will change the circuit's protection characteristics.

Best replacement path

Consider parts from the same BSMD2920 series, but carefully check hold current. BSMD2920-300-33V is a potential downgrade, while BSMD2920-500-30V is an upgrade in current.

Main risk

The primary risk is mismatch in hold current, which can lead to either insufficient protection (if too high) or nuisance tripping (if too low).

Recommended alternatives

Parametric alternative in the same 2920 package with a higher voltage rating (33V) but a lower hold current (3A).
