The Molex BERGSTIK 93690-103-34LF is a 34-position dual-row unshrouded breakaway header on the standard 0.100" (2.54 mm) pitch grid. The press-fit and solder through-hole termination option means this header can be pressed into a plated-through hole for solderless backplane assembly or wave-soldered in a conventional PCB flow. The 0.100" (2.54 mm) row spacing mirrors the pitch, so the footprint lands on a standard 0.100" grid in both axes, which keeps board layout tools and routing rules predictable.
The 0.177" (4.50 mm) post length projects through a standard PCB. Mating pin length is 0.224" (5.70 mm). The press-fit option uses the square pin geometry to cold-work the plated-through hole — no solder, no flux residue.
Within the BERGSTIK breakaway header family, the 93690-103-34LF sits as the 34-position dual-row variant. The decision between them is purely a circuit-count match to the BOM; the footprint pattern and receptacle mate are identical per position. No other functional difference drives a selection trade-off.
