20-position IDC receptacle for 24 AWG ribbon or discrete wire
The TE Connectivity MTA-100 5-640441-0 is a 20-position, single-row IDC receptacle built for mass-terminating 24 AWG discrete or ribbon cable. The 0.100" (2.54 mm) pitch matches the standard MTA-100 header footprint — the same spacing used across the series for board-to-wire interconnects. The closed-end design prevents stubbing on the header pins during mating, and the white housing makes wire identification straightforward in a harness bundle.
Termination and wiring — IDC for 24 AWG only
It's sized specifically for 24 AWG wire; the IDC slot geometry won't reliably terminate a thinner or thicker gauge.
Mating and sourcing — what fits and where to get it
The 5-640441-0 mates with any MTA-100 0.100" pitch header — the 20-position male pin strip (e.g., TE 640445-2 or similar) is the direct match. The locking ramp engages the header's latch ramp to hold the pair together. No separate crimp tool needed; the IDC termination is done with a simple press, which keeps assembly fast for volume harness builds.
