The closed-end design prevents stubbing against the header shroud, and the locking ramp provides positive retention once mated. The 0.100\" (2.54mm) pitch is the industry-standard spacing for this connector class — it matches the board footprint of any MTA-100 header. The 28 AWG wire gauge is fixed by the IDC slot geometry — using a different gauge risks an intermittent termination or a loose wire in the crimp zone. The locking ramp engages audibly, confirming the receptacle is fully seated on the header. ## Where This Connector Gets Used The MTA-100 IDC receptacle is a workhorse for internal wire-to-board harnesses in appliances, HVAC controls, vending machines, and industrial panels. The discrete or ribbon cable acceptance covers both point-to-point wiring and multi-conductor ribbon runs. The locking ramp makes it suitable for applications with moderate vibration — the audible latch gives the line assembler a go/no-go check without a pull test. ## Sourcing This Part Confirm the BOM position count and the mating header pitch before committing — the 0.100\" (2.54mm) pitch and 5-position count are the only match points.","metaTitle":"TE MTA-100 3-643816-5, 5 Pos IDC Receptacle, 0.100\" Pitch","metaDescription":"TE MTA-100 3-643816-5 5-position IDC receptacle, 0.100\" pitch, 28 AWG, tin 80.0µin, locking ramp, ROHS3.
