Is there a pin-compatible replacement for CS1V101M-CRE77?

A verified pin-to-pin replacement is not available. The Lelon VZH101M1VTR-0810 is a strong form-fit-function candidate that may be pin-compatible, but its land pattern and vertical clearance must be checked against your design.

What risks should I check before replacing CS1V101M-CRE77?

First, verify the package dimensions (diameter x height) and PCB land pattern. Second, confirm secondary electrical parameters like ESR and ripple current from the datasheets are suitable for your application.

AI replacement insight

Package riskhigh

Most candidates have different footprints, requiring PCB changes.

Electrical risklow

Many candidates meet or exceed voltage, temp, and life ratings.

Can it be replaced directly?

No exact drop-in replacement has been verified. The Lelon VZH101M1VTR-0810 is a form-fit-function alternative with a slightly shorter body that should be evaluated for mechanical fit.

Best replacement path

The Lelon VZH101M1VTR-0810 is the strongest candidate, offering a nearly identical package (8x10mm) and upgraded electricals like AEC-Q200 qualification. It requires verification of the land pattern.

Main risk

The primary risk is mechanical incompatibility. Most alternatives have different package dimensions, requiring a PCB layout change. Even the closest match has a slightly different height.

Recommended alternatives

AEC-Q200 qualified alternative with a wider temperature range and very similar 8mm diameter package.
