The single-row, free-hanging (in-line) housing accepts the matching MTA-156 header, and the locking ramp provides audible positive retention against vibration or cable strain. ## IDC Termination and Contact Finish Tin is the cost-effective choice for moderate mating-cycle applications where gold's corrosion resistance is not required; the thick plating ensures reliable gas-tight connections over the service life. ## Wire Gauge and Cable Type The receptacle accepts 18 AWG wire, specified for both discrete and ribbon cable. The IDC slot geometry is sized for that gauge — using a thinner wire may not achieve the required insulation displacement force, while thicker wire risks damaging the contact beam. Stick with 18 AWG for a reliable termination.","metaTitle":"TE MTA-156 3-644465-4, 4-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-644465-4 4-position IDC receptacle, 0.156\" (3.96mm) pitch, 18 AWG, tin-plated contacts, locking ramp.
