AI replacement insight

Package riskhigh

All candidates have different footprints, requiring PCB redesign.

Electrical risklow

Candidates have matching inductance and equal or better current/DCR ratings.

Can it be replaced directly?

No direct, drop-in replacement was found. All reviewed alternatives require board layout changes due to different package sizes.

Best replacement path

Use a functional alternate like FCH1050-330M for better electrical performance, if the larger footprint is acceptable.

Main risk

Package/footprint mismatch is the primary risk, making all candidates incompatible without a PCB redesign.

Recommended alternatives

Functional upgrade with higher current and lower DCR, but in a larger package (10.3x10.5mm).
