Is there a pin-compatible replacement for T520B227M006ATE035?

No, a direct pin-compatible replacement for T520B227M006ATE035 was not found. All identified functional alternatives use a larger package (EIA D-Case 7343) than the target's B-Case (3528), which prevents a drop-in replacement.

What risks should I check before replacing T520B227M006ATE035?

The main risk is the package mismatch; you must verify your PCB layout can accommodate a larger EIA 7343 case. Also, check the ESR of any alternative; while some are better, others can be significantly worse and impact circuit stability.

T520B227M006ATE035 Alternatives, Datasheet & Cross Reference | KEMET

Finding a substitute for the KEMET T520B227M006ATE035, a 220µF 6.3V low-ESR polymer tantalum capacitor, requires careful review. While no direct pin-compatible options were found, several functional alternatives exist with superior electricals in a larger package.

AI replacement insight

Package riskhigh

Alternatives are in a larger case (EIA 7343 vs 3528), requiring board redesign.

Electrical risklow

Many alternatives offer equivalent or better voltage and ESR ratings.

Sourcing risklow

Alternatives from major manufacturers like Panasonic are widely available.

Can it be replaced directly?

No direct pin-compatible replacement was found. All suitable alternatives have a larger package size (EIA D-Case 7343) compared to the target's EIA B-Case (3528).

Best replacement path

Use a functional alternative like Panasonic's 10TPE220ML, which offers superior electrical performance but requires changing the PCB layout to accommodate the larger EIA D-Case package.

Main risk

The primary risk is mechanical incompatibility. All viable alternatives require a larger footprint on the circuit board, making them unsuitable as drop-in replacements.

Recommended alternatives

A functional alternative with better ESR and higher voltage, but in a larger package requiring board redesign.
