40-Pin Workhorse for Board-to-Board Links
In a lab or field-service board that gets reconnected a few dozen times a year, that plating budget covers the product lifetime comfortably. For applications where vibration is present, a secondary locking receptacle or a wire-retention feature on the cable side is worth planning for.
The 69192-202HLF is a 2-position version of the same dual-row, unshrouded layout. Both share the 0.100-inch pitch, 3 A rating, and black UL94 V-0 housing, but the 202HLF carries 15 µinch gold plating instead of 30 µinch — a cost trade-off if the mating cycle count stays low. The 67997-172HLF is a 72-position dual-row header with the same 30 µinch gold and 0.100-inch pitch. The difference is termination: the 67997 uses a straight solder tail (no kink), while the 69192-140HLF uses a kinked pin for better retention in the plated through-hole before soldering.
