Board-fit and pitch constraints
The 5-103639-3: Shrouded on all four walls, the header guides the mating receptacle and protects the square male pins from bending during assembly or service.
Sourcing and compliance status
Available in tube packaging; sourced to order against the BOM quantity. Confirm the mating half and position count before committing the line.
Mating and application context
Style is board to board or cable, meaning this header mates with a receptacle housing crimp terminals or a board-mount socket — the latch holder fastening type provides audible lock confirmation during mating. The keying slot in the housing prevents mis-mating with non-keyed receptacles, a useful feature in multi-connector panels where a wrong mate could short a signal line.
