Product details

7-Position IDC Receptacle for MTA-156 Harnesses

The 0.156" (3.96mm) pitch matches the MTA-156 header footprint — the same pitch used across the series, so the IDC slot lines up with the conductor spacing on standard 0.156" ribbon cable. Watch pin-one every press: the closed-end feature stops the cable from pushing through the back of the housing, which keeps the termination depth consistent across all 7 positions. The orange colour makes this 7-position part easy to spot on a bench with other MTA-156 receptacles in different position counts.

No stripping, no crimping. The free-hanging mount means this receptacle lives at the end of a cable, not on a board. It mates with the standard MTA-156 header (male pin header, 0.156" pitch, 7 positions).

Frequently asked questions

Is 3-640431-7 compatible with standard MTA-156 headers?

Yes, the 3-640431-7 mates with any standard MTA-156 male pin header (same series, 0.156" pitch, 7 positions). The IDC termination is on the receptacle side; the header is through-hole or surface-mount on the PCB.

What wire gauge does 3-640431-7 support?

The 3-640431-7 is rated for 18 AWG discrete or ribbon cable, terminated via IDC. The slot geometry is sized for this gauge — using a different wire size risks a poor gas-tight joint.
