AI replacement insight

Package riskhigh

All candidates require a PCB layout change. None are drop-in replacements.

Electrical riskmedium

Candidates have variations in DCR and saturation current that must be evaluated for the specific application.

Can it be replaced directly?

No direct pin-for-pin replacements were identified. All suitable candidates have different package dimensions, requiring a PCB layout change.

Best replacement path

FXL1350-470-M is the strongest functional alternative if a PCB redesign is possible. It offers improved current ratings with a minor DCR trade-off.

Main risk

The primary risk is mechanical incompatibility, as no candidates share the same package dimensions as the target.

Recommended alternatives

A functional alternative with similar inductance and improved current ratings, but a different package and higher DCR.
