The 68602-130HLF: The through-hole termination and 0.150" (3.81 mm) post length suit it for single- or double-sided boards where the header sits flush against the board surface.
Within the same 68602 base series, the 30-position 68602-130HLF shares the same 0.100" pitch, dual-row layout, 3 A rating, and 30 µinch gold plating with the 16-position 68602-116HLF, the 10-position 68602-110HLF, and the 8-position 68602-108HLF. The choice is purely a matter of the required circuit count — all other mechanical and electrical specs are identical.
