MTA-100 IDC Receptacle, 18 Circuits, 0.100" Pitch
The TE Connectivity 1-640440-8 is an 18-position MTA-100 receptacle that terminates discrete or ribbon cable via IDC at 22 AWG. The 0.100" (2.54mm) pitch matches the standard MTA-100 header footprint — the circuit count is the only BOM variable to confirm against your harness schematic. The single-row, closed-end design with a locking ramp gives a positive audible latch when mated to a standard MTA-100 header, which is the primary retention in vibration-prone assemblies like appliance or HVAC control harnesses.
IDC Termination — Wire Gauge Is Non-Negotiable
This receptacle is designed for 22 AWG wire only. The IDC slot geometry and insulation displacement beam are sized for that specific conductor diameter.
Mating and Mounting — Free-Hanging Right-Angle
The receptacle mounts free-hanging (in-line) and exits at a right angle to the wire axis, which keeps the cable bundle parallel to the board edge in a tight enclosure. The locking ramp on the housing mates with the ramp on a standard MTA-100 header — the latch is the same across the series, so any MTA-100 header with the same circuit count and pitch will engage. The closed end prevents the IDC contacts from being exposed at the wire entry, reducing the chance of accidental shorting during handling.
Lifecycle and Sourcing
The 1-640440-8 carries an Active lifecycle status — no end-of-life notice or last-time-buy window to track. The part is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. There is no official replacement or cross-reference on record, so the 18-position count and 0.100" pitch are the only fit criteria to validate against your BOM.
