Is there a pin-compatible replacement for CS1C101M-CRE54?

No direct pin-compatible replacement has been verified. Potential alternatives like the KNSCHA XT series have a different package height and require physical clearance and land pattern verification before use.

What risks should I check before replacing CS1C101M-CRE54?

The primary risk is physical incompatibility. Check the candidate's package dimensions (diameter and height) against your PCB layout and clearance. Also verify secondary electricals like ripple current and ESR from the datasheet.

Finding a substitute for the CS1C101M-CRE54 100µF 16V capacitor involves checking key electricals and, critically, physical dimensions. While several functional alternatives exist, they may differ in height, requiring careful board-level verification.

AI replacement insight

Package riskhigh

Candidates are 2.3mm taller than the target part, requiring careful board layout and clearance verification.

Electrical risklow

Candidates have matching or superior voltage ratings and identical capacitance and tolerance.

Can it be replaced directly?

No direct drop-in replacement has been identified. All viable candidates are taller and require a physical clearance check on the PCB.

Best replacement path

Upgrade to a higher voltage part like KNSCHA XT100UF35V90RV0065, but verify package height.

Main risk

Physical package mismatch, specifically a taller component height that may cause interference.

Recommended alternatives

A functional alternative with matching electricals but different package height (7.7mm).
