Nichicon
Pin-compatible alternative from the same manufacturer with matching core specs but lower performance.
Find and compare replacements for the Nichicon UUD1H101MNL1GS, a 100µF 50V low-impedance aluminum electrolytic capacitor. This guide analyzes pin-compatible options and functional alternatives to help you make an informed decision.
Pin-compatible options may have weaker ripple current or impedance specs.
Most functional alternatives have different package dimensions, requiring layout changes.
Direct replacement for UUD1H101MNL1GS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for UUD1H101MNL1GS, then review parametric alternatives for package and electrical fit.
The primary risk is performance degradation (lower ripple current, higher impedance) even with pin-compatible parts, or package mismatch requiring a PCB redesign.
