4-Position IDC Connector for 24 AWG Discrete Wire — SMT Right-Angle

The 3-2106431-4: Both the cable pitch and the board-side pitch are 0.157" (4.00 mm), so the wire spacing matches the PCB footprint directly — no pitch transition. The housing is Natural in colour and includes a Feed Through feature, meaning the wires pass straight through the connector body rather than terminating at a stub end — this simplifies daisy-chain or pass-through wiring in a harness.

IDC Termination for Individual Wires — Not Ribbon Cable

This connector uses IDC (Insulation Displacement Contact) termination, but it is specified for Individual Wires — not a flat ribbon cable. The wire gauge is fixed at 24 AWG; the IDC slot geometry is sized for that single diameter, so using a different gauge risks an unreliable termination or damaged contacts.

SMT Line Feed — Tape & Reel Packaging

For a high-volume SMT line, the reel option feeds directly into a pick-and-place machine without a tray changeover. Cut Tape suits prototype runs or low-volume builds where a full reel is unnecessary.

Frequently asked questions

What is the cable pitch and board-side pitch of 3-2106431-4?

Both the cable pitch and the board-side pitch are 0.157" (4.00 mm). This means the wire spacing matches the PCB footprint directly — there is no pitch change through the connector.

Is 3-2106431-4 available in tape and reel packaging?

Yes, it is available in Tape & Reel (TR) and Cut Tape (CT) packaging. The reel option is suitable for automated SMT placement; Cut Tape works for prototype or low-volume builds.

Can 3-2106431-4 be used with 24 AWG wires only?

Yes, the connector is specified for 24 AWG wire only. The IDC slot geometry is sized for that single gauge — using a different wire size may result in an unreliable termination.

Is 3-2106431-4 RoHS compliant?

Yes, it is ROHS3 Compliant, covering all ten restricted substances including the four phthalates. No exemption documentation is needed for EU-market builds.
