The closed end and polarizing key mean you can't accidentally reverse the connector in its mating header — a detail that saves a rework when the harness is already taped up. ## Why the IDC Termination and 22 AWG Limit Matter on the Bench IDC termination means no crimp tool, no loose terminals to feed — you lay the ribbon cable or discrete wires into the slot and press. The trade-off is wire gauge: the 3-644463-8 is specced for 22 AWG only. Trying to stuff 18 AWG into the IDC slot risks damaging the contact beam or getting an intermittent connection that shows up weeks later as a field failure. If your application sees frequent disconnect-reconnect cycles, you'd want gold-plated contacts from a different MTA-156 variant. The 1-1703095-1 is the same MTA-156 family — same IDC termination, same free-hanging mount — but a 4-position receptacle on a 0.197\" (5.00mm) pitch, not the 0.156\" (3.96mm) of the 3-644463-8. That pitch difference means the 1-1703095-1 is physically wider per contact and uses a latch lock instead of the polarizing key. If your board layout is already set for 0.156\" pitch headers, the 1-1703095-1 won't fit without a new footprint. The 8-position count of the 3-644463-8 matches a standard 8-circuit BOM line; the 4-position peer is for smaller harness drops.","metaTitle":"TE MTA-156 3-644463-8 Receptacle, 8 Pos IDC, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-644463-8 8-position IDC receptacle, 0.156\" (3.96mm) pitch, tin contacts, 22 AWG, RoHS.
