Electrical riskhigh

Technology mismatch (Tantalum vs MLCC) affects capacitance stability and failure mode.

Package riskhigh

No candidates match the 7343-31 (D Case) package, requiring PCB redesign.

Can it be replaced directly?

No direct pin-compatible replacement has been identified. All candidates require engineering review due to differences in package, technology (Tantalum vs. Ceramic), or key parameters.

Best replacement path

Consider other solid or polymer tantalum capacitors in an EIA 7343 (D case) package. Ceramic capacitors (MLCCs) are not direct replacements and require significant design review.

Main risk

The primary risk is substituting a Tantalum capacitor with a Ceramic (MLCC) type, which can lead to unexpected circuit behavior due to DC bias derating and different failure modes.

Recommended alternatives

A functional alternative with different package and wider tolerance; requires engineering review.
