This receptacle is specified for 22 AWG wire only — the IDC slot dimensions and insulation displacement beam are sized for that gauge. Using a different wire size will not achieve a gas-tight connection and risks intermittent contact or wire push-out. The IDC termination accepts discrete wires or ribbon cable, and the closed-end feature stops the contacts from sliding out the back of the housing during assembly or service. ## Polarizing Key and Header Compatibility The polarizing key (a raised rib inside the housing) aligns with a matching slot on the MTA-156 header, ensuring the receptacle cannot be mated backwards or with a non-keyed header. This is a one-way key — it does not allow multiple keying positions. The 0.156\" pitch and single-row layout are standard across the MTA-156 series, so this 6-position receptacle mates with any 6-position MTA-156 header (straight or right-angle, through-hole or surface-mount) that has the corresponding keyway. ## Current and Voltage Rating Context While the MTA-156 series is rated by TE Connectivity for up to 5 A per contact and 250 VAC, the exact derating depends on wire gauge, ambient temperature, and the number of adjacent circuits carrying current simultaneously. At 22 AWG with all 6 positions loaded, the practical current limit is typically 3-4 A per contact at 25 °C ambient to stay within the 30 °C temperature rise limit of the housing material. The 0.156\" pitch provides enough creepage distance for the 250 V rating in dry indoor environments.","metaTitle":"3-644463-6 TE MTA-156 Receptacle, 6 Pos IDC, 22 AWG","metaDescription":"TE MTA-156 3-644463-6 receptacle, 6 positions, 0.156\" pitch, IDC termination for 22 AWG discrete or ribbon cable.
