Product details

0.156" Pitch, 8-Position IDC Receptacle for Harness Builds

The 0.156" (3.96mm) pitch matches the standard MTA-156 header grid, so the board footprint is fixed — no layout guesswork. IDC termination means the 18 AWG wire is pushed directly into the slot, displacing the insulation; no crimp tool or loose terminal is needed, which keeps the harness build simple and repeatable. The tin contact finish at 80.0µin (2.03µm) is thick enough to bite through wire oxide and hold a gas-tight joint over temperature cycles — this is the standard MTA-156 plating, not a thin flash.

Closed-End Housing for Wire Stops

This receptacle has a closed end, meaning the housing is solid at the back — the wire stops at the end of the slot rather than passing through. That gives a positive wire-stop for consistent insertion depth, which matters when the harness is built on a line where the operator feeds wire by feel.

Frequently asked questions

What wire gauge does 3-640426-8 accept?

The 3-640426-8 is rated for 18 AWG discrete wire. The IDC slot is sized for that gauge — using a thinner or thicker wire will not achieve a reliable gas-tight joint.

What is the pitch of 3-640426-8?

The pitch is 0.156" (3.96mm), which is the standard MTA-156 grid. It mates with any MTA-156 header of the same pitch and position count.
