What risks should I check before replacing T520B107M006ATE040?

Key risks include package mismatch, higher ESR, and different capacitance. Ensure the replacement has an equivalent SMD package (e.g., 3528), ESR at or below 40mΩ, and the same 100µF capacitance.

T520B107M006ATE040 Alternatives, Datasheet & Cross Reference | KEMET

T520B107M006ATE040 is a 100µF 6.3V tantalum polymer capacitor from KEMET in a 3528 package, valued for its low ESR. Finding a substitute requires matching capacitance, voltage, ESR, and package.

AI replacement insight

Electrical riskmedium

Must match low ESR (≤40mΩ) and ripple current.

Package riskhigh

Many parts have similar values but different packages. Must be 3528 chip.

Can it be replaced directly?

Direct replacement for T520B107M006ATE040 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best path is cross-referencing to other manufacturers' tantalum polymer capacitors in a 3528 package, like Panasonic's TPE series.

Main risk

The main risk is substituting with a different capacitor technology, like aluminum electrolytic, which will have a vastly different ESR and footprint.

Recommended alternatives

A strong alternative with matching key parameters and slightly better ESR in an equivalent package.
