What risks should I check before replacing CS1A102M-CRF10?

The main risk is mechanical incompatibility. Verify the candidate's package dimensions and PCB land pattern against the target's datasheet. Also check for any differences in ESR and ripple current ratings for your application.

CS1A102M-CRF10 Alternatives, Datasheet & Cross Reference | ST

CS1A102M-CRF10 is a 1000µF 10V surface-mount aluminum electrolytic capacitor. Several potential alternatives exist with similar or upgraded electrical specifications, but require careful package and land pattern verification.

AI replacement insight

Electrical risklow

Candidates match or exceed key electrical ratings like voltage and capacitance.

Package riskmedium

Candidates have similar but not identical package dimensions. Land pattern must be verified.

Can it be replaced directly?

Direct replacement for CS1A102M-CRF10 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ROQANG VT1A102M1010 offers the most direct replacement path, but requires datasheet review of the land pattern.

Main risk

Package and land pattern mismatch is the primary risk across all candidates.

Recommended alternatives

Strong electrical match. Package is very similar but requires verification.
