Is there a pin-compatible replacement for MPX224K31D2KN15800?

Not in this list. While some parts are electrically similar, they have a 10mm lead pitch instead of the required 15mm, making them physically incompatible without board changes.

What risks should I check before replacing MPX224K31D2KN15800?

First, verify the lead pitch is 15mm. Second, ensure capacitance is 0.22µF ±10%. Third, confirm it has an X2 safety rating and voltage rating of at least 275VAC. Any deviation requires circuit analysis.

AI replacement insight

Package riskhigh

Several candidates have a 10mm pitch instead of 15mm.

Electrical riskhigh

One candidate has a matching package but 50% higher capacitance.

Sourcing risklow

The target part is active, but finding an exact match may require searching other brands.

Can it be replaced directly?

No, a direct pin-compatible replacement was not identified in this review. All candidates have critical differences in package or capacitance.

Best replacement path

No direct drop-in replacement found. The best path is to find another 0.22µF X2 capacitor with a 15mm lead pitch from a different manufacturer.

Main risk

The primary risk is physical incompatibility due to mismatched lead pitch, or functional incompatibility from different capacitance values.

Recommended alternatives

A functional alternative with the same capacitance but a smaller 10mm lead pitch, not a direct fit.
