Board Layout and Pitch Match
A single-wall shroud and friction lock keep the header mated under moderate vibration — the lock is a ramp on the shroud that snaps into the matching receptacle housing.

Critical for PCB layout compatibility before purchase.
Sourcing buyers need immediate availability to fill BOM lines.
Direct query for cost comparison across distributors.
Compliance mandatory for many applications; missing info blocks purchase.
Ensures full connector system compatibility for design engineers.
Critical for brokers checking lifecycle and for finding alternative sources.
