The TE Connectivity AMPMODU MTE 103957-3 is a 4-position, single-row IDC receptacle designed for mass-termination to 22-26 AWG discrete or ribbon cable. The closed-end feature prevents contact stubbing during wire insertion.
IDC termination eliminates individual crimping — the 22-26 AWG wire is pressed into the insulation-displacement slot, making gas-tight contact with the gold-plated female socket. The free-hanging (in-line) mounting style lets the receptacle float in the cable bundle, reducing strain on the IDC joint.
Confirm the header's pin count and orientation — the single-row layout is keyed by the latch position, so a 4-position header is the correct mate.
