MMKP223J3A1001
KYET
Needs validationlow risk
Strong candidate with matching lead pitch, capacitance, and tolerance, plus a higher voltage rating.
Best Alternatives to KP223J2J1001
The KYET KP223J2J1001 is a 22nF, 630V, ±5% metallized polypropylene film capacitor with a 10mm lead pitch. Finding a replacement requires matching capacitance, voltage, tolerance, and physical lead spacing.
AI replacement insight
Package riskhigh
Many similar parts have different lead pitches (e.g., 7.5mm, 20mm); 10mm must be confirmed.
Electrical riskmedium
Ensure tolerance is ±5% or tighter and capacitor type (e.g., X2 vs general) is appropriate.
Can it be replaced directly?
Direct replacement for KP223J2J1001 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The strongest alternative is KYET MMKP223J3A1001, which matches key specs and lead pitch, offering a higher voltage rating.
Main risk
The primary risk is physical incompatibility due to different lead pitches in many potential alternatives. Electrical risks include tolerance and capacitor type differences.
