The closed-end design (black housing) prevents stubbing during cable insertion and keeps the IDC slots aligned for consistent termination. Bulk packaging suits low-to-mid volume harness builds where individual handling is preferred over tape-and-reel feeding. IDC termination eliminates the need for a separate crimp tool — the 24 AWG wire is pressed into the insulation-displacement slots as the cover is seated. The 24 AWG wire gauge is the specified size; the connector is not rated for 22 AWG without a different MTA-100 variant. The free-hanging or right-angle mounting option means the cable can exit inline with the header or turn 90° at the connector face, useful when routing into a tight enclosure corner. There is no official replacement or cross-reference from TE for this order code.","metaTitle":"TE Connectivity 3-644312-4 MTA-100 Receptacle, 4 Pos, IDC","metaDescription":"TE MTA-100 4-position IDC receptacle, 0.100\" pitch, tin contacts, 24 AWG, locking ramp.
