Best Alternatives to CA45A-P-10V-10uF-K

Package: P (2012 Metric)NHTantalum CapacitorsCapacitance: 10 µFRated Voltage: 10 VTolerance: ±10%Case Code: POperating Temperature: -55°C to 125°C

CA45A-P-10V-10uF-K is a compact 10uF 10V tantalum capacitor in a 2012 package. While no drop-in replacements are available, functional alternatives exist but require careful review of their larger package sizes and electrical characteristics.

AI replacement insight

Package riskhigh

All candidates have different, larger footprints requiring PCB redesign.

Electrical riskmedium

Risk is medium if switching to Aluminum Electrolytic due to different ESR and leakage properties.

Sourcing risklow

The proposed alternatives are widely available from multiple manufacturers.

Can it be replaced directly?

No direct, drop-in replacement is available. The target's P-case (2012) is much smaller than any identified alternatives, requiring a board redesign.

Best replacement path

Use a tantalum capacitor with the same specs in a different package, like CA45-B-20V-10uF-K, and adapt the PCB layout.

Main risk

Physical incompatibility. All alternatives are in larger packages that are not footprint-compatible with the target's 2012 case.
