Is there a pin-compatible replacement for EMZA350ARA101MF80G?

Yes, EMZR500ARA101MF80G is a pin-compatible replacement. It shares the same 6.3mm x 7.7mm SMD package and 2-pin layout, and offers superior electrical characteristics, making it a low-risk upgrade.

What risks should I check before replacing EMZA350ARA101MF80G?

Before replacing, you must verify the ESR (impedance) and ripple current ratings. The target is a low-impedance part; using a standard capacitor with higher ESR can cause overheating and circuit failure. Also check for technology differences, like the higher leakage current of polymer capacitors.

AI replacement insight

Electrical riskhigh

High if ESR and ripple current are not matched or improved. The target is a low-impedance part.

Package risklow

Most candidates share the same 6.3mm x 7.7mm SMD package, ensuring form-fit compatibility.

Sourcing riskmedium

Availability of specialized low-ESR capacitors can vary. Verify stock for chosen alternative.

Can it be replaced directly?

Yes, the NCC EMZR500ARA101MF80G is a strong candidate for direct replacement, as it is an upgrade from the same manufacturer in the same product family.

Best replacement path

The NCC EMZR500ARA101MF80G is the best replacement, offering an upgrade in voltage and ripple current while matching all other critical parameters.

Main risk

The main risk is substituting with a general-purpose capacitor that has higher ESR or lower ripple current, which can cause overheating and failure in low-impedance power applications.

Recommended alternatives

Upgrade with higher voltage (50V) and ripple current (350mA) in the same package and from the same manufacturer.
