What this 20-position breakaway header does
The 0022284204: This is a vertical unshrouded header from the Molex KK254 series (42375 family), designed for board-to-board or cable interconnects. The breakaway construction means you can snap the strip to a shorter length if your BOM calls for fewer than 20 circuits, though the part ships with all 20 positions intact. Applications span automotive, general purpose, medical, and telecommunications — the UL94 V-0 nylon housing and the gold contact finish are the two features that make this header suitable for those environments. The through-hole mounting gives a robust mechanical anchor against cable strain, which matters when the header is mated to a wire-harness receptacle.
The push-pull fastening means no secondary latch — the retention comes from the friction of the gold-on-gold or gold-on-tin interface. For vibration-prone assemblies, consider a shrouded header with a locking ramp instead. The insulator height above the board is 0.090" (2.29 mm), which sets the z-height clearance for the mating receptacle. The square pin profile (0.025" square typical for KK254) ensures reliable contact wipe during mating.
