Product details

It terminates discrete 18 AWG wires via an insulation displacement contact (IDC), so the cable is stripped and pressed into the slot — no crimp tool or loose terminals needed. Tin-plated contacts suit applications where the mating cycle count stays moderate; the natural-colored housing is a visual match for harnesses where color-coding the connector body helps during assembly.

Packaging for the Line

This part ships in Tape & Reel (TR) packaging, with Cut Tape (CT) also available. The reel format feeds directly into a pick-and-place machine for the SMD reflow process — no tray handling or tube loading required. The Feed Through feature means the IDC slot is open on both sides, so the wire can pass straight through the connector body, which simplifies daisy-chain or pass-through wiring in the harness.

Frequently asked questions

What wire gauge does the 2106431-3 support?

The 2106431-3 terminates 18 AWG wire via its IDC slot. The insulation displacement contact is sized for that specific gauge — using a different wire size may not achieve a reliable connection.

Is the 2106431-3 a surface mount connector?

Yes, the 2106431-3 is a surface-mount, right-angle connector. It is designed for reflow soldering onto the PCB, with the wire entry parallel to the board surface.

What is the pitch of the 2106431-3?

This single-row pitch determines the footprint spacing and the cable ribbon width.
