The Amphenol BERGSTIK II 68004-202 is a 2-position unshrouded male pin header on a 0.100" (2.54 mm) pitch, designed for board-to-board stacking through a standard through-hole solder process. This is the simplest member of the BERGSTIK II family — two square pins in a single row, push-pull retention, no latch or shroud.
The 0.100" (2.54 mm) pitch is the standard 0.1-inch grid — the footprint is two plated through holes on that spacing, no surprises for a board layout. The overall contact length of 0.525" (13.34 mm) splits into a 0.318" (8.08 mm) mating tail and a 0.107" (2.71 mm) solder post, so the mated stack height is set by the receptacle's own insulation height.
For a form-fit-function cross, look for a 2-position 0.100" pitch unshrouded header from the same BERGSTIK II series — the pitch, pin count, and through-hole footprint are the fixed dimensions; the contact finish and plating thickness may vary by the replacement variant. The last-time-buy window has closed on the manufacturer side, so sourcing runs through independent distribution surplus or broker inventory.
