Is there a pin-compatible replacement for CA45-D-10V-220uF-K?

Yes, several parts use the same D (7343) case size. However, electrical parameters like tolerance (±10% vs ±20%) and operating temperature (125°C vs 105°C) often differ and must be verified for your application.

What risks should I check before replacing CA45-D-10V-220uF-K?

Key risks include wider capacitance tolerance (±20% vs ±10%) affecting circuit precision, and a lower maximum operating temperature (105°C vs 125°C) which could impact reliability in high-temperature environments.

CA45-D-10V-220uF-K Alternatives, Datasheet & Cross Reference | TORCH

Finding a substitute for the TORCH CA45-D-10V-220uF-K 220µF 10V tantalum capacitor involves checking key parameters. Alternatives exist in the same package but may have different tolerance or temperature ratings requiring review.

AI replacement insight

Electrical riskmedium

Wider tolerance and lower temperature rating require circuit validation.

Package risklow

Alternatives in the standard D (7343) case are available.

Can it be replaced directly?

No direct drop-in replacement with identical specifications has been identified. All viable alternatives require a review of parametric differences.

Best replacement path

Use a parametric alternative in the same D (7343) package, but verify the impact of wider tolerance and lower temperature rating.

Main risk

The primary risks are the looser capacitance tolerance (±20% vs ±10%) and the reduced maximum operating temperature (105°C vs 125°C).

Recommended alternatives

Form-fit alternative with better ESR, but requires review for its wider tolerance and reduced temperature range.
