Is there a pin-compatible replacement for PX105K2C1503?

KYET's PX684K2C1502 has the same 15mm lead pitch but a lower capacitance (0.68uF vs 1uF). This makes it mechanically compatible but requires electrical validation for your application.

What risks should I check before replacing PX105K2C1503?

Verify the replacement has an X2 safety rating and 310VAC (or higher) voltage. Check the lead pitch (target is 15mm) for mechanical fit and ensure capacitance is 1uF to maintain EMI filtering performance.

AI replacement insight

Package riskmedium

Alternatives have different lead pitches or require electrical re-evaluation.

Electrical risklow

Functional alternatives exist, but capacitance or other parameters may differ.

Can it be replaced directly?

No direct pin-for-pin replacement was found. Alternatives require review of either electrical parameters (capacitance) or mechanical fit (lead pitch).

Best replacement path

The best path is finding a functional alternative like KYET PX105K2C2202, which matches electrically but requires checking mechanical fit due to a different lead pitch.

Main risk

The main risks are mechanical incompatibility from different lead pitches or degraded performance from different capacitance values.

Recommended alternatives

A functional alternative with matching electrical specs but a different lead pitch, requiring mechanical verification.
