Is there a pin-compatible replacement for CMLO1040H470MTT?

No verified pin-to-pin replacement is available. FXC1040-470M has a similar footprint (11.5x10.3mm vs 10.8x10mm) but requires layout verification.

What risks should I check before replacing CMLO1040H470MTT?

Key risks include: 1) Higher DC Resistance (DCR) causing lower efficiency, 2) Lower thermal current (Irms) causing overheating, and 3) Package size mismatch requiring PCB redesign.

AI replacement insight

Electrical riskhigh

Candidates have higher DCR or lower thermal current.

Package riskhigh

Most candidates have different footprints requiring PCB redesign.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates require review of electrical parameters or package dimensions.

Best replacement path

The best path is a 47µH inductor in a 10x10mm package with Irms ≥ 3.0A and DCR ≤ 101mΩ. FXC1040-470M is a potential candidate if higher DCR is acceptable.

Main risk

The main risks are increased power loss from higher DC Resistance (DCR) or thermal failure from lower thermal current (Irms) ratings.

Recommended alternatives

A functional alternative with matching current ratings but higher DCR and a slightly different package.
