The 68602-440HLF: Unshrouded headers like this one give the designer flexibility in choosing the mating receptacle's stack height — the 0.230" mating pin length accommodates most standard box headers and IDC sockets without bottoming out. The UL94 V-0 housing ensures the connector does not propagate flame inside the equipment.
Sourced through independent distribution channels against an RFQ.
The difference is overall contact length: 0.480" on the 68602 vs 0.538" on the 68691. The longer post on the 68691 gives extra standoff for thicker PCBs or deeper receptacles — choose the 68602 for standard 1.6mm boards and the 68691 when the mating socket sits higher off the board.
