Is there a pin-compatible replacement for 6TPE150MAZB?

Yes, parts in the same B2 (3528) package are pin-compatible. However, key electrical parameters like capacitance must be closely matched. For example, 6TPE100MAZB is pin-compatible but has lower capacitance.

What risks should I check before replacing 6TPE150MAZB?

The main risks are changes in capacitance and ESR. Using a capacitor with lower capacitance (e.g., 100µF vs 150µF) can affect power supply stability and transient response. Always verify performance in your circuit.

6TPE150MAZB Alternatives, Datasheet & Cross Reference | PANASONIC

Panasonic's 6TPE150MAZB is a 150µF 6.3V polymer tantalum capacitor in a B2 package. Finding a direct drop-in is challenging, but alternatives with the same package and voltage exist, often requiring a review of capacitance.

AI replacement insight

Electrical riskmedium

Lower capacitance can impact transient response and system stability.

Package risklow

Alternatives in the same B2/3528 package are available.

Can it be replaced directly?

No direct 1:1 replacement with identical key parameters was found in this review. Alternatives require a trade-off, primarily on capacitance.

Best replacement path

Use a parametric alternative with the same package (B2/3528) and voltage (6.3V), but accept a lower capacitance (e.g., 100µF) and verify circuit performance.

Main risk

Reduced capacitance, which may compromise bulk decoupling effectiveness and power rail stability.

Recommended alternatives

A form-fit compatible capacitor from the same series with identical voltage and ESR, but lower 100µF capacitance.
