What risks should I check before replacing KP104J2G1016?

When replacing KP104J2G1016, check for: 1) Voltage Rating: Must be 400V or higher. 2) Package: Must be radial with 10mm lead pitch for a drop-in fit. 3) Tolerance: A wider tolerance (e.g., ±10%) may affect circuit performance. 4) Capacitor Type: Do not substitute with electrolytic or safety capacitors without a full circuit review.

KP104J2G1016 Alternatives, Datasheet & Cross Reference | KYET

AI replacement insight

Package riskmedium

Many similar parts exist with different lead pitches (e.g., 7.5mm, 15mm) that will not fit the PCB.

Electrical risklow

If key parameters (Voltage, Capacitance, Tolerance) are matched or improved, electrical risk is low.

Can it be replaced directly?

Direct replacement for KP104J2G1016 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best replacement path is to select a metallized polypropylene film capacitor with 100nF capacitance, a voltage rating of 400V or higher, ±5% tolerance, and a radial package with 10mm lead pitch.

Main risk

The main risk is selecting a part with an incorrect package lead pitch (e.g., 7.5mm) or a different capacitor technology (e.g., electrolytic, safety-rated) which have different electrical characteristics and may not fit or function correctly.

Recommended alternatives

A potential pin-compatible replacement with a higher voltage rating (630V) and wider temperature range.
