4P 5.08mm right-angle candidate, but 250V rating is below the target.
KF2EDGRC-5.08-4P is a 4-position 5.08mm right-angle pluggable terminal block header. Alternatives need pinout, footprint, and mating-plug review.
One 4P candidate is only 250V.
Pitch matches, footprint not checked.
Passive connector; no firmware.
Lifecycle data is limited.
No verified pin-compatible replacement is confirmed from the provided data.
Prefer same KF2EDGRC 4P series evidence or verify X5050WR-04S-N2SN if 250V is acceptable.
Voltage downgrade and unverified mechanical mating.
