Is there a pin-compatible replacement for CY75-47UH?

No, a direct pin-compatible replacement for CY75-47UH was not found. All functional alternatives require changes to the PCB layout due to different package dimensions.

What risks should I check before replacing CY75-47UH?

The main risk is the package mismatch; you must redesign your PCB layout. You should also verify the saturation current (Isat) and thermal performance in your specific application, as the target's Isat is not specified.

AI replacement insight

Package riskhigh

All candidates have different footprints, requiring mandatory PCB redesign.

Electrical riskmedium

Target's saturation current is unknown. Candidate's Isat and dynamic performance must be verified in-circuit.

Can it be replaced directly?

No, there are no direct pin-for-pin replacements for CY75-47UH among the candidates reviewed. All viable alternatives have different package sizes and require a PCB layout modification.

Best replacement path

For new designs or board revisions, FCH1050-470M offers a significant electrical upgrade. If space is constrained, no direct replacement was found, and a circuit re-evaluation is necessary.

Main risk

The primary risk is the physical package mismatch, which makes all candidates incompatible without a board redesign. A secondary risk is the unknown saturation current of the target part.

Recommended alternatives

Strong functional alternative with excellent electrical ratings in a larger package.
