AI replacement insight

Package riskhigh

No candidates match the 4.4x4.2mm footprint. A board redesign is mandatory for all options.

Electrical risklow

All candidates offer superior current ratings and lower DCR, reducing electrical stress.

Sourcing risklow

Candidates are from the same and different manufacturers, providing sourcing flexibility.

Can it be replaced directly?

No, a direct, pin-compatible replacement for the FXL0420-2R2-M was not identified. All suitable alternatives have different package footprints.

Best replacement path

If a PCB redesign is possible, FXL0530-2R2-M is the best upgrade path, offering improved electrical performance in the most similarly sized package.

Main risk

The primary risk is the package mismatch. All functional alternatives are physically larger and require a PCB layout modification to be used.

Recommended alternatives

A functional upgrade with higher current ratings, but requires a board redesign due to a larger footprint.
