Board-fit and circuit count
The 45280-2401: The 24 positions match a 24-way receptacle — count your BOM positions before committing, because a 24-circuit header won't fit a 22-circuit housing without leaving two pins floating.
Compliance and mating
ROHS3 compliant — fits lead-free assembly requirements. Mates with the matching Micro-Fit 3.0 receptacle housing (crimp or IDC type). The vertical orientation keeps the cable axis perpendicular to the board, which helps in tight z-height builds where a right-angle header would crowd the board edge.
