Is there a pin-compatible replacement for CA55-E025M107TE080?

No. The target part uses a 7343-43 Tantalum style package. All reviewed candidates use different SMD or through-hole packages and are not pin-compatible.

What risks should I check before replacing CA55-E025M107TE080?

The main risks are physical and electrical. The package footprint is different, requiring a PCB layout change. Electrically, switching from Polymer Tantalum to Aluminum Electrolytic will change the ESR, leakage current, and high-frequency performance, which must be validated in your circuit.

CA55-E025M107TE080 Alternatives, Datasheet & Cross Reference | Hunan Xiangyee Electronic Technology Co., Ltd.

Finding a substitute for the CA55-E025M107TE080, a 100µF 25V Polymer Tantalum capacitor, is challenging. While functional alternatives exist, none are direct drop-in replacements due to package and technology differences.

AI replacement insight

All candidates have different footprints requiring PCB redesign.

Electrical riskhigh

Switching from Polymer Tantalum to Aluminum Electrolytic affects ESR, leakage, and frequency response.

Can it be replaced directly?

No, a direct, drop-in replacement for CA55-E025M107TE080 was not found. All candidates require board layout changes and electrical validation.

Best replacement path

Search for Polymer Tantalum or Polymer Aluminum capacitors with 100uF/25V specs in a 7343 (EIA Case D) package.

Main risk

The primary risks are incompatible package footprints and significant differences in electrical performance (ESR, leakage) due to technology mismatch.

Recommended alternatives

Functional alternative with higher voltage, but different package and technology requires full re-qualification.
