The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, and the closed-end housing prevents inserting more than four wires — no accidental over-stuffing on the harness line. It terminates 18 AWG wire via IDC slots, so you skip crimping individual contacts; a single press stroke seats all four wires at once. For new builds requiring RoHS compliance, the tin-plated variant 3-640431-4 is the direct drop-in.

Frequently asked questions
Is 640431-4 RoHS compliant?
No, 640431-4 is RoHS non-compliant due to its tin-lead contact finish. For a RoHS-compliant drop-in, use the tin-plated variant 3-640431-4, which shares the same pitch, position count, and IDC termination.
What is the pitch of 640431-4?
The pitch is 0.156" (3.96mm), standard for the MTA-156 series. This matches the header footprint and sets the wire spacing for the IDC termination.
