Pin-compatible alternative with matching core specs, but requires review due to much higher ESR.
Finding a substitute for the Vishay 593D106X9025C2TE3 tantalum capacitor requires checking key parameters. This 10µF, 25V, 6032-28 capacitor has several potential alternatives, but careful attention must be paid to ESR and package size.
Most alternatives have 2-3x higher ESR, which can affect circuit stability and efficiency.
Pin-compatible options in the same 6032-28 package are available.
Direct replacement for 593D106X9025C2TE3 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for 593D106X9025C2TE3, then review parametric alternatives for package and electrical fit.
The primary risk is the significantly higher ESR of most alternatives, which can impact performance in power filtering and decoupling applications.
