AI replacement insight

Electrical risklow

Upgrading voltage is safe; other parameters are matched or improved on best candidates.

Package riskmedium

Many similar parts exist in different case sizes. Verify the 'A' case code (3216).

Sourcing risklow

This is a common capacitor value with multiple cross-vendor options available.

Can it be replaced directly?

Yes, CA45B-A-16V-10uF-K and CA45A-A-16V-10uF-K are pin-compatible upgrades with higher voltage ratings and improved ESR.

Best replacement path

Upgrade to a 16V version in the same package, such as CA45B-A-16V-10uF-K, for increased voltage margin.

Main risk

The primary risk is selecting an alternative with a different package size (e.g., Case B instead of Case A), which will not fit the PCB footprint.
