Is there a pin-compatible replacement for ERT226M2WI16RR?

No, we have not identified a pin-compatible replacement with the same 12.5x16mm package. All functional alternatives require verification of physical fit due to different dimensions.

What risks should I check before replacing ERT226M2WI16RR?

Before replacing, check three main risks: 1) Physical fit, as alternatives are larger. 2) Electrical stress, as voltage ratings match but are not higher. 3) Performance parameters like ESR and ripple current, which can affect circuit stability and lifetime.

ERT226M2WI16RR Alternatives, Datasheet & Cross Reference | Man Yue Technology Holdings Limited

Finding a substitute for the MAN YUE ERT226M2WI16RR, a 22uF 450V capacitor, requires careful review. While functional alternatives exist, they differ in package size, posing a physical fit risk.

AI replacement insight

Package riskhigh

Candidates are larger in diameter and/or length.

Electrical riskmedium

Voltage matches but lacks safety margin. ESR and ripple current must be verified.

Can it be replaced directly?

No, a direct drop-in replacement for ERT226M2WI16RR was not found. Viable alternatives have different physical dimensions and require board layout verification.
