Product details

Board-to-Board Stacking with the Dubox™ 68683-321

The tin-plated solder tails (100µin) are compatible with standard wave-solder profiles.

Supplied in tube packaging for through-hole assembly lines. The base product number 68683 covers the Dubox™ receptacle family — confirm the position count and plating option against the BOM line before committing.

In a vibration-prone assembly, a locking header variant or board-mount retention is worth evaluating. The square contact shape (0.025" square typical for Dubox™) mates with the header's square pin — confirm the header pin profile matches.

Frequently asked questions

What is the closest pin-compatible alternative to the 68683-321?

The 68683-321 is a Dubox™ series receptacle. A pin-compatible alternative would be another Dubox™ 42-position, 2.54mm pitch, dual-row receptacle with the same gold plating and through-hole termination. Confirm the contact finish thickness and insulation height match the application before substituting.
