5-Pin Right-Angle MTA-100 Header — BOM Fit Check
The 2-644803-5: This is a 5-position, single-row, shrouded header from the MTA-100 series, with a 0.100" (2.54mm) pitch — the standard footprint for wire-to-board connections on 0.100" ribbon or discrete wire harnesses. The right-angle orientation places the pin axis parallel to the PCB, saving vertical clearance in tight enclosures. Rated for 250VAC and operating from -55°C to 105°C, it fits general-purpose industrial and consumer equipment where the board sits inside a cabinet.
Friction Lock and Shrouded Walls — Vibration-Proof Mating
The friction lock engages with the matching MTA-100 receptacle housing, providing a positive detent that resists accidental disconnection under vibration or cable tug. The four-wall shroud protects the male pins from bending during mating and prevents misalignment with the female connector. Tin-on-tin contact finish is cost-effective for moderate mating cycles — expect several dozen insertions before wear becomes a concern.
