What this connector is
The Amphenol BERGSTIK 93690-103-10LF is a 10-position, dual-row unshrouded breakaway header in the BERGSTIK series — designed for board-to-board or cable interconnect at 0.100" (2.54 mm) pitch. All 10 circuits are populated in the standard build. The male pin is square-profile, through-hole mounted with a press-fit lead-in zone that pre-seats the contact before reflow — useful for wave-soldered assemblies where the pin needs initial retention before the solder joint forms. The mating interface carries gold GXT plating at 30.0 µin (0.76 µm), while the solder-tail post is tin-plated at 39.4 µin (1.00 µm). The mixed plating is a deliberate split: the gold on the mating face handles repeated engagement cycles and maintains low contact resistance at first mate; the heavier tin on the post gives a reliable solder-wetable surface. At 5 A per circuit the 93690-103-10LF sits squarely in signal-and-low-power duty — the 110 V rating covers industrial control logic and signal bus rails without reaching into power distribution territory. The housing is black thermoplastic rated UL94 V-0, and the insulation height of 0.100" (2.54 mm) sets the standoff from the board surface. The push-pull fastening type means the header relies on pin-to-socket interference for retention — no separate locking latch, so verify the mating half has adequate normal force if the assembly sees vibration.
Where it sits in the series
The BERGSTIK 93690 series is a dual-row, 2.54 mm pitch breakaway family. The 93690-103-10LF is the 10-position member. The breakaway construction means the header can be掰split to a smaller position count in the field — a single strip covers multiple circuit counts without a separate part number. This is the primary advantage of the breakaway format over fixed-position single-row strips.
Board layout and termination
Through-hole press-fit plus solder termination. The press-fit lead-in pre-seats the pin in the plated through-hole before wave or reflow solder reflow — it reduces pin float during wave soldering and helps keep the header square to the board during assembly. The post length of 0.177" (4.50 mm) and overall contact length of 0.505" (12.83 mm) define the board-side lead-in and should be checked against your PCB thickness and solder process window. The dual-beam mating contact length is 0.224" (5.70 mm) — the length of the engagement zone on the mating side. Confirm the compatible receptacle provides full beam engagement over this length; under-engagement reduces normal force and cycle life.
Sourcing and availability
The BERGSTIK 93690 series has no listed successor or cross-reference for this position count. Confirm the specific circuit count and plating variant against the part code before committing to a BOM change.
