Is there a pin-compatible replacement for ERK2GM330G200T?

No direct pin-to-pin replacement with identical package dimensions has been identified. However, alternatives with the same 10mm diameter and lead spacing exist, but are shorter, which is usually acceptable.

What risks should I check before replacing ERK2GM330G200T?

Key risks include package size differences, which can affect mechanical fit and thermal performance, and ripple current rating, which is critical for power supply applications. Always compare datasheets.

ERK2GM330G200T Alternatives, Datasheet & Cross Reference | AISHI

Finding a replacement for the AISHI ERK2GM330G200T, a 33µF 400V radial capacitor, involves matching key electricals and physical dimensions. Alternatives exist but may require verifying package size and ripple current.

AI replacement insight

Electrical riskmedium

Ripple current and ESR must be verified from datasheets.

Package risklow

Shorter package with same diameter usually fits without issue.

Can it be replaced directly?

No direct, drop-in replacement has been confirmed. Alternatives require engineering review of package size and ripple current.

Best replacement path

Use a functional alternative with identical capacitance and voltage, like KNSCHA 87EC0493, but verify the shorter package and ripple current rating are acceptable for your design.

Main risk

The main risk is a mismatch in package size or ripple current rating, which could affect reliability and performance.

Recommended alternatives

Functional alternative with matching electrical ratings but a slightly shorter package height.
