Pitch and Plating Drive the Fit
The 20021311-00008T1LF: The 1.27mm pitch sets a tight board footprint — at 0.050" centerline, routing one trace between pads on a standard PCB requires a 0.2mm trace width and clearance budget. Eight positions in two rows, all loaded. The dual-row layout keeps the connector body narrow, which helps when the board edge has limited real estate between mounting holes.
Through-Hole Anchor for Board Stacking
In a vibration-free enclosure, that is fine. If the assembly sees shock, the board-to-board pair needs a secondary retention method.
Mating Half and Series Position
It mates with a pin header from the same series — look for the matching 8-position, 1.27mm pitch, dual-row header. The Minitek127 family covers 2 to 50 positions in single and dual rows.
