Is there a pin-compatible replacement for 100PX100MEFC10X16?

No candidates have been confirmed as 100% pin-compatible. The Rubycon 100YXJ100M10X20 is the most likely to be compatible but is physically longer. Always verify case dimensions and lead spacing from the datasheet before replacing.

What risks should I check before replacing 100PX100MEFC10X16?

The main risks are physical and electrical. Check that the substitute's case size (diameter, length) and lead spacing fit your PCB. Also, verify that its ESR, ripple current rating, and lifetime meet your application's requirements.

AI replacement insight

Package riskhigh

Substitutes may have different dimensions, preventing proper PCB fit.

Electrical riskmedium

ESR, ripple current, and lifetime ratings are often unspecified and must be checked for application suitability.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. The closest options require checking physical dimensions and secondary electrical parameters like ESR and ripple current.

Best replacement path

The Rubycon 100YXJ100M10X20 is the strongest candidate, sharing key specs and manufacturer, but is 4mm longer. Verify physical clearance before ordering.

Main risk

Physical incompatibility due to different case sizes (diameter, length, lead spacing) is the primary risk when substituting this part.

Recommended alternatives

Strong electrical match from the same manufacturer, but is 4mm longer. Verify physical fit.
