Functional alternative with identical electrical ratings but different package dimensions; requires layout verification.
MMKP223J3A1001 is a 22nF, 1000V metallized polypropylene film capacitor. Finding a substitute requires matching key electricals and the 10mm lead pitch.
No candidates found with matching 10mm lead pitch. Board modification is required.
Candidates with matching or superior voltage and capacitance are available.
No direct, pin-compatible replacements have been verified. All candidates require careful review of physical dimensions before use.
Functional alternatives with matching electricals exist, but all require PCB layout changes due to different lead spacing.
Package mismatch is the main risk; the 10mm lead spacing of the original part is not matched by otherwise suitable candidates.
