Is there a pin-compatible replacement for 293D226X9025D2TE3?

Yes, T491D226K035AT from KEMET uses the same 7343-31 (D-Case) package and is considered pin-compatible. Its voltage rating is higher (35V vs 25V), which is a safe upgrade.

What risks should I check before replacing 293D226X9025D2TE3?

Key risks include package mismatch, requiring a PCB layout change. Also, switching from Tantalum to MLCC technology introduces different electrical behaviors like DC bias derating, leakage current, and ESR characteristics that must be validated in your circuit.

AI replacement insight

Package riskhigh

High for non-D-case parts, requiring PCB redesign.

Electrical riskhigh

High when switching from Tantalum to MLCC technology due to different behaviors.

Sourcing risklow

Multiple vendors produce similar Tantalum and MLCC capacitors.

Can it be replaced directly?

Yes, KEMET's T491D226K035AT is a strong candidate for direct replacement, offering improved voltage and ESR specifications in the same physical package.

Best replacement path

Upgrade to T491D226K035AT for a higher voltage rating in the same package.

Main risk

The primary risk is using an alternative with a different package, which requires a new PCB layout. Switching to MLCC technology is a high electrical risk.

Recommended alternatives

Pin-compatible upgrade with a higher 35V rating and lower ESR in the same D-case package.
