Is there a pin-compatible replacement for 50V1000uF CD288?

Currently, no replacement has been fully verified as pin-compatible without review. The CapXon KM102M050I250A is a strong candidate for form-fit-function, but its shorter body and unconfirmed dynamic specs mean you must perform a datasheet review before considering it a drop-in part.

What risks should I check before replacing 50V1000uF CD288?

Before replacing, check three main things: 1) Physical dimensions (diameter and length) to ensure it fits. 2) Voltage rating must be equal or higher. 3) Dynamic parameters like ESR and Ripple Current must be equal or better than the original to ensure stability and prevent overheating.

50V1000uF CD288 Alternatives, Datasheet & Cross Reference | HRK

AI replacement insight

Package riskmedium

Many alternatives have different diameters or lengths, preventing a drop-in fit.

Electrical riskmedium

ESR, ripple current, and lifetime are critical for electrolytic capacitors and must be verified from datasheets.

Sourcing risklow

1000uF/50V is a common value with many potential manufacturers.

Can it be replaced directly?

No verified direct, pin-to-pin replacement has been identified. The closest candidate, KM102M050I250A, has a different physical length and requires datasheet review for critical parameters like ESR and ripple current before it can be considered a drop-in replacement.

Best replacement path

The CapXon KM102M050I250A is the most promising path, matching key electricals and diameter. However, it is shorter and requires datasheet verification of dynamic parameters like ESR and ripple current.

Main risk

The primary risk is a mismatch in physical dimensions (package size) or unverified dynamic electrical parameters like ESR and ripple current, which can affect circuit performance and reliability.

Recommended alternatives

A strong alternative with matching key electricals and diameter, but is physically shorter and requires datasheet review.
