The Molex 93690-103-48LF is the 48-circuit member of the BERGSTIK dual-row header series, rated 5 A per contact at 0.100-inch (2.54 mm) pitch. All 48 positions are loaded — a fully populated dual-row header with 0.100-inch row spacing, suitable for board-to-board or cable-side interconnects where board routing density and stack-height budget call for a standard-profile 2.54 mm pitch part. Contact finishing uses a bifurcated approach: the mating interface carries gold (GXT) at 30.0 µin (0.76 µm), which governs mating-cycle life and initial insertion resistance at the pin interface, while the post side is tin-plated at 39.4 µin (1.00 µm) for solder-wetted and press-fit tail integrity. The overall contact length is 0.505 inch (12.83 mm) with a 0.224-inch (5.70 mm) mating pin length. The housing is black thermoplastic rated UL94 V-0 with a 0.100-inch (2.54 mm) insulation height. Voltage rating is 110 V, and the connector carries a push-push (push-pull in source) fastening type — no locking latch, no polarizing key, and no shroud, so mis-mate protection relies entirely on the pin-count and pitch alignment with the mating receptacle. Termination is through-hole, supporting both solder and press-fit tail insertion — the dual-termination designation means the post accepts board insertion with interference fit as well as conventional wave or hand-soldering. Post length is 0.177 inch (4.50 mm) from the shoulder.
Where this fits
At 48 positions in a dual-row layout, this is the largest position-count member buyers typically source from the BERGSTIK 93690 base number range for mid-density board-to-board applications. The 5 A per contact rating is adequate for signal and low-level power routing; the bifurcated gold-on-mating / tin-on-post plating is the right choice when the connector will see multiple mating cycles or when the circuit runs through a board-edge zone where a tin-only finish would degrade faster under fretting.
Sourcing posture
Carries an Active lifecycle status — quoted to order against BOM quantity with no stated last-time-buy date or successor on record. The base product number 93690 is shared across the series; confirm the full 93690-103-48LF order code against your BOM line before committing. No official cross-reference is listed.
