HE2031A33MPR is a 3.3V, 400mA LDO in a SOT89 package with a high 25V input rating. Finding a direct replacement requires careful checking of input voltage and package compatibility.

AI replacement insight

Electrical riskhigh

All candidates have lower input voltage ratings than the target's 25V.

Package riskmedium

Only one candidate matches the SOT89 package; others require board redesign.

Can it be replaced directly?

Direct replacement for HE2031A33MPR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ME6119A33PG offers the same SOT89 package but requires verifying if the lower 18V max input voltage is acceptable for your application.

Main risk

The primary risk is the lower maximum input voltage of all candidates, which could lead to device failure if the application's input exceeds their ratings.
