The 68459-472HLF is a 72-position unshrouded male pin header from the BERGSTIK® II series, built for board-to-board stacking applications. It uses a 0.100" (2.54mm) pitch across two rows with the same 0.100" row spacing, giving a dense but routable footprint for backplane or mezzanine interconnects. The right-angle through-hole termination keeps the connector parallel to the board edge, which suits space-constrained enclosures where the mating board slides in from the side. Tin plating on both the mating surface and the solder tails is rated for 5 A per contact — adequate for general-purpose signal and moderate power duty, though the tin finish limits the mating cycle count compared to gold. The UL94 V-0 rated black housing meets the flame requirement for equipment inside an enclosure.
Key ratings and what they mean for the fit
The 0.100" pitch and row spacing define the board footprint — each pin sits on a 2.54mm grid, which is a standard layout that matches legacy bus architectures and prototyping grids. The 0.318" (8.08mm) mating pin length gives enough reach to engage a standard box receptacle or a socket strip, while the 0.150" (3.81mm) solder post length is sized for a typical 0.062" PCB with through-hole soldering. The 5 A per contact rating is the thermal limit at room temperature; in a 72-position header, the total current through the connector is limited by the sum of the active circuits and the derating at elevated ambient temperatures. The tin plating on the mating surface is 100.0µin (2.54µm) thick, which provides good corrosion resistance for moderate mating cycles — expect a few hundred cycles before wear-through becomes a concern.
