The yellow housing is a visual key for the MTA-156 family; the closed-end design and polarizing key prevent wire over-insertion and mis-mating during harness assembly. ## IDC Termination and Contact Plating No stripping, no crimping: one press operation terminates all 6 positions simultaneously. The 80.0µin (2.03µm) tin contact finish is a heavy plating — thicker than the 15-30µin typical on signal-grade IDC connectors — so it handles the higher insertion forces of 20 AWG without galling the contact surface. ## Active Lifecycle and Sourcing Sourcing is straightforward: this is a current-production MTA-156 member. The 6-position count and 0.156\" pitch are common — the matching header half (a 6-position, 0.156\" pitch, straight or right-angle pin header) is widely available across the TE MTA-156 line. Confirm the header's pin length and orientation to your board stack-up before committing the BOM. ## Mating and Field Fit This receptacle mates with any standard MTA-156 6-position header — through-hole or surface-mount, straight or right-angle — as long as the header uses 0.045\" square pins on 0.156\" centers. For field replacement: the IDC termination is permanent — you cannot remove and re-terminate a wire in the same slot. If a wire is damaged, the entire receptacle is replaced. The 20 AWG wire gauge is fixed by the IDC slot geometry; using 18 AWG or 22 AWG will not achieve a reliable gas-tight connection.","metaTitle":"TE MTA-156 3-643818-6, 6-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-643818-6 receptacle, 6 positions, 0.156\" (3.96mm) pitch, IDC termination for 20 AWG wire.
