The 0022288304: This unshrouded header mates with Molex KK series crimp housings (e.g., 2695, 6471, 5045 families) and IDC sockets. The male pin is square, 0.025" square typical for KK series, and accepts the standard KK crimp terminal.
No official replacement or successor has been announced. The base product number 002228 covers the KK254 breakaway header family; the full 0022288304 suffix specifies the 30-position, right-angle, gold-plated variant.
Both are 30-position KK254 headers, but 0022288304 is a right-angle through-hole variant, while 0022288305 is a straight (vertical) through-hole variant. Pitch, plating, and circuit count are identical.
