82-Position Right-Angle Receptacle for Board-to-Board Stacking
The 89883-441LF is a Dubox™ series receptacle from Amphenol ICC (FCI), designed for board-to-board interconnects. Tin is a reliable, cost-effective finish for moderate mating-cycle applications — think one-time assembly or periodic field service, not daily disconnect. For high-cycle duty (500+ matings), a gold-plated sibling in the Dubox family would be the better fit. The blue insulation colour helps visual identification on a crowded board.
Footprint and Mating Compatibility
In a vibration environment, consider a header with a friction lock or add a secondary retention mechanism. The post length is 0.114" (2.90mm) — a standard through-hole length for 1.6mm-thick PCBs. The tin post finish (78.7µin) is compatible with wave soldering and common lead-free profiles.
