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. The locking ramp on the housing mates with the matching header ramp for positive retention in moderate vibration environments. ## 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.","metaTitle":"TE MTA-156 3-640426-8, 8 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE MTA-156 3-640426-8 8-position IDC receptacle, 0.156\" pitch, 18 AWG, tin plating, locking ramp.
