AI replacement insight

Package riskhigh

Most alternatives are in different packages, requiring a PCB redesign.

Electrical riskhigh

The only package-compatible option has a 50% lower power rating.

Can it be replaced directly?

No direct, risk-free drop-in replacement was found. The closest package match, LM3Z24VT1G, has a significant power downgrade.

Best replacement path

Functional alternatives with higher power ratings (e.g., LBZT52C24T1G) are available but require a board spin due to different packages.

Main risk

The primary risks are either mechanical incompatibility (package mismatch) or electrical overstress (power downgrade).
