KYET
Electrically identical to the target but requires physical adaptation due to a different lead pitch.
Finding a substitute for the KYET KP223J2J0701, a 22nF 630V film capacitor, requires careful attention to its 7.5mm lead pitch. While several parts offer matching or better electrical specs, they have different physical dimensions.
Lead pitch mismatch requires lead bending or PCB modification, which may not be feasible.
Several candidates match or exceed key electrical ratings like voltage and temperature.
Alternatives from the same manufacturer (KYET) and others are available.
No direct, pin-for-pin replacements were identified. All suitable alternatives require mechanical adaptation due to different lead pitches.
Use KP223J2J1001, which is electrically identical, and bend the leads to fit the 7.5mm spacing if board layout allows.
The primary risk is mechanical incompatibility. All viable candidates have a wider lead pitch (10mm or more) than the target's 7.5mm.
