KYET
A potential pin-compatible replacement from KYET with matching capacitance, package, and a higher voltage rating.
Reviewing alternatives for the KNSCHA MPX474K31D4KN15800, a 0.47µF 275VAC X2 safety capacitor. Key considerations for substitutes are matching capacitance, safety ratings, and the 15mm radial lead pitch.
Low if capacitance and voltage ratings are matched or improved.
Low if the 15mm lead pitch is matched.
Multiple manufacturers produce similar X2 capacitors.
Direct replacement for MPX474K31D4KN15800 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most promising path is a cross-vendor replacement like the KYET PX474K2C1506, which matches all critical parameters.
The main risk is altering the circuit's EMI filtering characteristics by using a part with a different capacitance value. Mechanical fit (lead pitch) is also critical.
