What risks should I check before replacing UCM1H101MCL1GS?

The main risk is the package mismatch. All alternatives are physically larger than the target's 6.3x7.7mm size, so you must verify that the new part will fit on your PCB, which may require a layout change.

UCM1H101MCL1GS Alternatives, Datasheet & Cross Reference | Nichicon

Find functional alternatives for the Nichicon UCM1H101MCL1GS 100µF 50V capacitor. While no drop-in replacements exist, several options offer similar electrical performance but require board layout verification due to larger package sizes.

AI replacement insight

Package riskhigh

All candidates have a larger footprint, requiring board redesign.

Electrical risklow

Candidates with matching or higher voltage ratings are available.

Can it be replaced directly?

Direct replacement for UCM1H101MCL1GS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use a functional alternative like Lelon VZH101M1HTR-0810, but you must verify the larger 8x10mm package fits your PCB layout.

Main risk

The primary risk is physical incompatibility. All alternatives are larger than the target's 6.3x7.7mm package and will not fit the same PCB footprint.

Recommended alternatives

Functionally similar with matching electricals but a larger package requiring layout verification.
