What This 10-Position Header Does in a Board-to-Wire Build
The 1-640383-0: Its 0.156" (3.96mm) pitch and single-row, 10-position layout are a direct fit for the matching MTA-156 crimp receptacle housing — a common pairing in power distribution and signal wiring inside industrial control panels and general-purpose equipment. The natural (off-white) colour is standard for MTA-156 headers and makes visual inspection of full pin insertion straightforward.
Pitch, Positions, and the Board Footprint
Voltage, Current, and Temperature Range
The header is rated 600VAC — high enough for 480VAC line-voltage circuits inside a cabinet. With 18 AWG wire, expect 7-8 A per contact; with 22 AWG, derate to around 4 A. The glass-filled thermoplastic housing maintains dimensional stability across the range.
It is ROHS3 compliant.
