The onsemi MC7815CD2TR4G is a 15V, 1A linear voltage regulator in a D2PAK-3 package. When seeking alternatives, focus on matching the package, pinout, and key electrical ratings like output voltage and current.

AI replacement insight

Package riskhigh

Many alternatives use different packages (DPAK, TO-220) that are not physically compatible.

Electrical risklow

Most 7815 variants have very similar core electrical specs, but secondary parameters like dropout can vary.

Sourcing risklow

The 7815 is a multi-sourced commodity part, but specific package types may have variable availability.

Can it be replaced directly?

Direct replacement for MC7815CD2TR4G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct replacement path is the L7815CD2T-TR, which matches the package and offers improved current handling.

Main risk

The main risk is using an alternative with a different package (like DPAK or TO-220), which is not a drop-in replacement and requires a board redesign.
