Is there a pin-compatible replacement for KP104J2G0701?

MPX104K31B4KN20600 shares the same 7.5mm lead pitch, making it form-fit compatible. However, its capacitance tolerance is wider at ±10% and it is an X2 safety capacitor, which must be reviewed for your application.

What risks should I check before replacing KP104J2G0701?

The primary risks are physical fit and electrical tolerance. Check if your board can accommodate a 10mm lead pitch instead of 7.5mm. If considering a part with matching pitch, verify if a wider ±10% capacitance tolerance is acceptable.

KP104J2G0701 Alternatives, Datasheet & Cross Reference | KYET

KYET KP104J2G0701 is a 100nF, 400V, ±5% film capacitor with a 7.5mm lead pitch. While no direct drop-in replacement is confirmed, several alternatives exist with variations in lead pitch or tolerance that require review.

AI replacement insight

Package riskhigh

Several alternatives have a 10mm lead pitch instead of the target's 7.5mm, requiring board modification.

Electrical riskmedium

One form-fit option has a wider tolerance (±10% vs ±5%), which could affect circuit timing or filtering.

Can it be replaced directly?

No direct, fully equivalent replacement has been identified. All viable alternatives require a trade-off in either physical package (lead pitch) or electrical parameters (tolerance).

Best replacement path

If board space allows for lead bending, KP104J2G1016 offers an identical electrical profile. If a drop-in fit is mandatory, MPX104K31B4KN20600 is an option if the wider tolerance is acceptable.

Main risk

The main risk is the package mismatch, as most electrically similar parts have a different lead pitch.

Recommended alternatives

An electrical match from the same manufacturer, but with a different lead pitch (10mm vs 7.5mm).
