Single-Wire IDC Termination for SMT Assembly
The TE 1-2106431-1 is a single-position IDC wire connector — a 1-circuit, 1-row termination point that accepts a 20 AWG conductor and terminates it via insulation displacement directly to a surface-mount right-angle footprint. This is not a multi-position ribbon cable header; it is a discrete wire-to-board IDC termination for one conductor, housed in a natural-colored body with tin-plated contacts.
What Drives the Fit on the Line
The 1-position count means this part terminates one wire at a time — it is not ganged into a multi-way IDC block. For a harness builder, each conductor gets its own connector body, which simplifies rework on a single wire without disturbing adjacent terminations. The 20 AWG wire gauge is the only size listed; the IDC slot is dimensioned for that specific conductor diameter, so verify the wire spec against the slot geometry before committing the BOM line. The surface-mount right-angle termination is the key packaging consideration.
The 1-2106431-1 is a single-wire IDC termination, while the 1-216791-6 is a 16-position DIP header for ribbon cable with a 0.050-inch cable pitch and through-hole press-fit mounting. The 1-2106431-1 serves a different assembly scenario — one conductor at a time, SMT placed, no ribbon cable alignment — so it is not a functional replacement or second-source for the 16-position header. The decision between them is driven by whether the build needs a single-wire SMT termination or a multi-conductor ribbon cable interface.
