The 640387-8: Packaged in bulk, which suits both prototype builds and production runs where tape-and-reel is not required.
The 600 VAC voltage rating and UL94 V-0 thermoplastic housing qualify this header for use in industrial control panels, general-purpose equipment, and other enclosed assemblies where flame-rated components are specified. For a given wire size, consult the MTA-156 terminal current derating curve.
Mates with MTA-156 receptacle housings (e.g., 640441 series) using standard 0.156" pitch crimp terminals. The friction lock aligns with the receptacle latch pocket; no adapter or keying insert is needed. The square pin profile provides reliable solder joint geometry.
