The 18 AWG wire gauge is specified for the slot geometry; using a different gauge risks an intermittent or high-resistance connection. The closed-end feature acts as a positive stop, so the wire bottoms out at the correct depth every time. For ribbon cable, the same IDC slot accepts the conductor without modification. ## Mating and Housing Fit This receptacle mates with the standard MTA-156 header (through-hole or vertical, 0.156\" pitch). The single-row, 5-position layout is keyed by the housing geometry; verify the header's position count and polarization before committing the BOM line.","metaTitle":"TE MTA-156 3-640431-5, 5-Pos IDC Receptacle, 18 AWG","metaDescription":"TE MTA-156 3-640431-5 5-position IDC receptacle, 0.156\" pitch, 18 AWG, tin plating.
