The Amphenol 86840-146HLF is a 46-position, dual-row BERGSTIK® II unshrouded header on the standard 0.100" (2.54mm) pitch. This is a board-to-board male pin header with a right-angle through-hole termination — the pins sit parallel to the PCB, which keeps the mated connector stack low against the board edge. All 46 positions are loaded, so the pinout matches the circuit count one-to-one.
Key Specs and What They Mean for the Fit
The 0.100" pitch is the legacy DIP/grid footprint — it drops onto a standard 0.100" hole pattern, which makes board layout straightforward but means the connector takes up about 4.6" of board edge for the full 46 positions. The 5A per-contact rating is typical for a signal-level header on this pitch; the limiting factor is the temperature rise in the housing, not the contact itself. Gold or GXT™ plating at 30.0µin (0.76µm) on the mating surface gives this header a solid mating-cycle life for repeated connect/disconnect in test or programming fixtures — not a one-time crimp-and-forget joint. The unshrouded design means there is no keying or polarization — the mating receptacle must be aligned manually. This is common for BergStik headers used in low-cost, high-density board stacking where the mating half is guided by the board alignment. The right-angle orientation places the pin row parallel to the board, which suits mezzanine or card-edge applications where the mating connector comes in from the side rather than from above.
Mounting and Termination
Through-hole right-angle mounting with solder termination. The contact length — mating side is 0.318" (8.08mm), post length is 0.230" (5.84mm). The insulation height sits at 0.190" (4.83mm) above the board. These dimensions matter for the mated stack height and for whether the solder tail clears components on the opposite side of the board. The housing is rated UL94 V-0, so it is acceptable for equipment inside an enclosure requiring a flame rating.
