30-Circuit Breakaway Header at 0.100-Inch Pitch
The 22-28-4301: This is a Molex KK 100 breakaway pin header, 30 circuits, tin-plated pins on a 0.100-inch pitch. Box packaging means it ships as a loose piece — suitable for hand-loading in low-volume production or prototyping, though not optimized for automated pick-and-place lines that expect tape-and-reel.
That means it can be ordered against a BOM line without the risk of a sudden discontinuation interrupting production runs. No stock-holding claim — each RFQ is sourced fresh from the multi-supplier network.
This breakaway header mates with any standard KK 100 crimp receptacle housing or IDC socket that accepts a 0.100-inch pitch, 30-position interface. The tin-plated pins are designed for moderate-cycle applications — if the assembly sees frequent field servicing, consider a gold-plated variant for extended mating cycle life. The breakaway construction lets you reduce the populated circuit count by snapping the header at the molded break points. This is useful when a single PCB layout serves multiple SKUs with different I/O counts — the same header stock covers 2 through 30 positions.
