Black housing, bulk packaged. This catches first-time buyers off guard — the housing alone cannot make a connection. Pair it with the correct Dynamic D-3100 crimp terminal (e.g., 1-917806-1 or similar depending on wire gauge) and the matching header (typically a 3-position, 3.81mm pitch Dynamic D-3100 header). The polarizing key aligns the housing to the header during assembly, so the keying feature on the header must match. ## 3.81mm Pitch, Single Row — Fit Check for the BOM Three positions on a 3.81mm pitch in a single row. That pitch is wider than the 2.54mm signal standard — it gives more creepage and room for power contacts, which is the design intent of the Dynamic D-3100 series. The single-row layout keeps the housing narrow, useful for tight harness routing. The 3.81mm pitch also matches the footprint of the mating header, so the board layout engineer gets a clean 3.81mm centerline. No board lock or panel-mount ears — this is strictly a wire-to-board or wire-to-wire in-line housing.","metaTitle":"TE Dynamic D-3100 1-178288-3 Receptacle Housing, 3 Pos","metaDescription":"TE Dynamic D-3100 1-178288-3 receptacle housing, 3 positions, 3.81mm pitch, single row, crimp termination, polarizing key, -55°C to 105°C.
