Is there a pin-compatible replacement for ERZ1HM101E12OTG?

Based on the provided data, no pin-compatible replacement has been confirmed. All candidates with matching electrical specifications have a different, non-compatible package (SMD) compared to the target's through-hole radial package.

What risks should I check before replacing ERZ1HM101E12OTG?

The main risk is the physical package and mounting type; the target is through-hole while many alternatives are SMD. Also verify electrical parameters like capacitance (100µF), voltage (50V or higher), tolerance (±20%), and secondary parameters like ESR, ripple current, and endurance to ensure they meet your application's needs.

ERZ1HM101E12OTG Alternatives, Datasheet & Cross Reference | AISHI

Finding a replacement for the AISHI ERZ1HM101E12OTG, a 100µF 50V through-hole capacitor, requires careful checking of package compatibility. While functional alternatives exist, direct pin-compatible substitutes require verification of form and fit.

AI replacement insight

Package riskhigh

Target is through-hole radial, while candidates are SMD. Requires board redesign.

Electrical risklow

Candidates with matching or superior voltage/capacitance are available if package is not a constraint.

Can it be replaced directly?

No direct pin-for-pin replacement has been verified. All functional matches have a different package type (SMD vs. Through-Hole), requiring a PCB redesign.

Best replacement path

Find a 100µF, 50V (or higher) aluminum electrolytic capacitor in a radial through-hole package with a 6.3mm diameter.

Main risk

The primary risk is the package mismatch. The target is a through-hole component, while potential alternatives are surface-mount (SMD), requiring a complete PCB layout change.

Recommended alternatives

Functionally similar with matching electricals, but requires board redesign due to different package (SMD vs. Through-Hole).
