It uses the standard 0.100" (2.54mm) pitch and row spacing, so it mates with any matching 0.100" pitch receptacle.
Three same-series peers — 68602-108HLF, 67997-108HLF, and 67996-108HLF — share the identical 8-position, dual-row layout, 0.100" pitch, 30.0µin gold plating, and UL94 V-0 black housing. The only difference is the overall contact length: 0.480" (12.19mm), 0.450" (11.43mm), and 0.425" (10.80mm) respectively, versus 0.588" (14.94mm) for the 87894-108HLF. That longer pin gives you more reach through the board for thicker PCB stacks or taller mating receptacles — pick the one whose post length clears your board thickness plus the mating connector's depth.
