21-Position Dubox Receptacle for Board-to-Board Stacking
The through-hole solder termination and 0.114" (2.90 mm) post length anchor the receptacle to the board, and the mated stack height of 11.04 mm defines the z-height budget between stacked PCBs — a dimension that must match the mating header's stacking height to avoid board stress.
Mating Header and Stack Height Compatibility
This receptacle mates with a 0.100" pitch, single-row, 21-position pin header — typically from the Dubox or BergStik II series — that provides the matching 11.04 mm mated stack height. Confirm the mating header's post length and stacking height against the 11.04 mm specification before committing the BOM; a header with a different stack height will shift the mated assembly out of its intended z-height envelope.
