Is there a pin-compatible replacement for EEEFK1H100UR?

No replacement has been verified as 100% pin-compatible. However, VD1H100MC054000CE0 and XT10UF50V90RV0071 have nearly identical package dimensions and are the most likely to fit the same PCB footprint, but require engineering verification.

What risks should I check before replacing EEEFK1H100UR?

Before replacing, you must verify the physical dimensions (diameter and height) to ensure it fits your PCB layout. Also, check secondary electrical parameters like ESR (impedance) and ripple current rating to ensure they meet your circuit's requirements.

AI replacement insight

Package riskmedium

Candidates have similar but not identical packages. Footprint and height must be verified.

Electrical risklow

Key parameters match or are improved, but secondary specs like ESR and ripple current need checking.

Can it be replaced directly?

No confirmed direct drop-in replacement exists. VD1H100MC054000CE0 is the most promising candidate for a form-fit-function replacement, pending physical verification.

Best replacement path

VD1H100MC054000CE0 is the best candidate, offering a very similar package and improved electricals. However, physical verification is still required.

Main risk

The primary risk is physical incompatibility. Even small differences in package dimensions can prevent a successful replacement on an existing PCB.

Recommended alternatives

A strong functional alternative with a very similar package and improved impedance and endurance.
