The 0.156\" (3.96mm) pitch matches the standard MTA-156 header footprint, and the free-hanging, in-line mounting suits wire-to-board harness runs where the receptacle lands on a mating header pinned to the PCB. ## Tin-Plated Contacts at 80.0 µ\" — Low-Cycle, Cost-Effective Duty The female socket contacts carry an 80.0 µ\" (2.03 µm) tin finish. Tin works fine for the current levels typical of 20 AWG wire in this series; the trade-off against gold is cycle life, not contact resistance at first mate. For a one-time mate in an appliance or industrial control panel, this is the cost-effective call. ## Mating Header and Harness Fit This receptacle mates with the standard MTA-156 header family — a single-row, 0.156\"-pitch pin header with the corresponding locking ramp feature. The closed-end housing means the back of the receptacle is sealed, so the IDC termination is enclosed and the wire entry is protected. The yellow housing colour is a visual aid in multi-wire harness bundles — you spot the MTA-156 run at a glance.","metaTitle":"TE MTA-156 3-640427-3, 3-Position IDC Receptacle","metaDescription":"TE MTA-156 3-640427-3 3-position IDC receptacle, 0.156\" pitch, tin-plated contacts, locking ramp.
