AI replacement insight

Electrical riskmedium

Candidates may have different power ratings or hold currents, requiring analysis.

Package risklow

All reviewed candidates use the same 2920 package, ensuring physical compatibility.

Can it be replaced directly?

No guaranteed drop-in replacement has been identified. SMD2920-500C-16V is a very close functional match that requires engineering review before substitution.

Best replacement path

Use SMD2920-500C-16V, but verify its lower power rating (1.5W vs 2.5W) is acceptable for the application's thermal environment.

Main risk

The primary risk when substituting is using a part with a different hold current, which will alter the circuit's overcurrent protection point.

Recommended alternatives

Functionally similar with identical hold current and voltage, but requires review of its lower power rating.
