Finding a replacement for the KNSCHA MPX105K31E3KN15800 1µF 275VAC X2 safety capacitor involves matching capacitance, voltage, safety ratings, and the 22.5mm lead pitch. Several alternatives exist, but require careful verification.

AI replacement insight

Package riskmedium

Many alternatives have incorrect lead pitch; verification is critical.

Electrical risklow

Ensure any replacement is X2 safety rated for at least 275VAC.

Can it be replaced directly?

Direct replacement for MPX105K31E3KN15800 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for MPX105K31E3KN15800, then review parametric alternatives for package and electrical fit.

Main risk

The main risk is package incompatibility. While some parts match electrically, their physical dimensions, especially lead pitch, may differ.
