Product details

What This Dubox Receptacle Does in a Board Stack

The through-hole solder tails (0.122" post length) anchor the connector into the board for mechanical stability.

The mating half is a Dubox series pin header (0.100" pitch, square pins). Confirm the header's post length and stacking height match your board-to-board gap — the receptacle's insulation height is 0.335" (8.51mm).

Housing and Compliance Details

The glass-filled thermoplastic housing is rated UL94 V-0, suitable for equipment enclosures requiring flame-retardant materials.
