AI replacement insight

Package riskhigh

No drop-in package found; all alternatives require a PCB redesign.

Electrical risklow

Candidates offer improved current handling and lower DCR, which is generally a safe upgrade.

Can it be replaced directly?

No direct, pin-compatible replacements were identified. All suitable alternatives require a PCB layout change.

Best replacement path

Use a functional alternative with superior electrical ratings, but plan for a PCB layout modification to accommodate the different package.

Main risk

The primary risk is the package mismatch. The footprint and dimensions of all high-quality alternatives are different from the target part.

Recommended alternatives

Electrically stronger alternative with higher current ratings, but requires PCB layout change due to different package size.
