Best Alternatives to T520B157M006ATE035

Package: 1411 (3528 Metric)KEMETTantalum - Polymer CapacitorsSeries: KO-CAP® T520Package: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Capacitance: 150 µFTolerance: ±20%Voltage - Rated: 6.3 V

KEMET's T520B157M006ATE035 is a 150µF, 6.3V Tantalum Polymer capacitor in a 3528 package. While no direct drop-in replacement exists, several alternatives are available that may require design changes.

AI replacement insight

Package riskhigh

Most alternatives are in larger packages, requiring a PCB redesign.

Electrical riskmedium

Changes in capacitance and ESR require circuit validation.

Sourcing risklow

The T520 series and similar parts are widely available.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was identified. The closest form-fit option has lower capacitance.

Best replacement path

If layout is fixed, T520B107M006ATE040 is a parametric downgrade. If layout can change, KEMET's T520 V-case parts offer better performance.

Main risk

The main risk is physical incompatibility, as most alternatives are in different packages. Electrical changes like lower capacitance are also a risk.
