What is the TE 3-644083-6 MTA-100 IDC Receptacle?
It uses a 0.100" (2.54mm) pitch, matching the industry-standard MTA-100 header footprint.
Where is the 3-644083-6 Used and What Are Its Key Features?
This connector is a wire-to-board IDC receptacle intended for internal harnesses in appliances, industrial controls, and consumer electronics where a reliable, low-cost mass-termination interconnect is needed. The IDC termination eliminates the need for individual crimp contacts and tooling — the cable is pressed directly into insulation-displacement slots in the housing. The 0.100" pitch is compatible with standard MTA-100 headers, and the 6-position count matches common signal and low-power circuit counts.
The 80.0 µin tin plating on the contacts is notably thick; standard tin flash is typically 50–60 µin. This extra thickness extends the number of mating cycles the contact can tolerate before the tin wears through to the base metal, which matters if the harness will be disconnected and reconnected during field service or testing. Tin is a good choice for low-voltage, low-current signal applications where gold's cost isn't justified.
