The Molex 55101-G11-02 is a 2-position member of the BERGSTIK® series — an unshrouded, single-row male pin header on the standard 0.100" (2.54mm) pitch. The contacts are square phosphor bronze pins with a gold GXT™ mating finish at 30.0µin (0.76µm) thickness, rated for 5A per circuit at 110V. The black UL94 V-0 housing uses push-pull fastening with no latch or shroud.
The 2-position 55101-G11-02 shares the same 0.100" pitch, right-angle orientation, and gold GXT plating as the 4-position 55101-G11-04. The difference is circuit count — 2 positions vs 4 — which determines the board footprint length and the number of signal or power lines it can carry. If your BOM calls for 4 circuits, the 55101-G11-04 is the direct same-series alternative at the same pitch and plating grade.
