AI replacement insight

Electrical risklow

Low risk if hold current matches; medium if it deviates.

Package risklow

All recommended candidates are in an identical 1206 package.

Can it be replaced directly?

Direct replacement for JK-nSMD100-13.2 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Prioritize candidates with identical 1.0A hold current and a higher voltage rating, such as SMD1206-100C-24V.

Main risk

The primary risk is a mismatch in the time-current trip curve, which could alter protection timing.
