The 89882-345LF: The right-angle through-hole orientation lets it sit at the board edge, mating with a matching pin header to create a parallel PCB stack. 45 circuits in a single row is a dense layout — it fits wide parallel buses or high-count signal bundles on one board edge without needing a second row.
30 µinch Gold Mating Finish — Field-Service Cycle Life
The mating contacts carry 30.0 µinch (0.76 µm) gold over nickel — a plating grade that supports 500+ mating cycles minimum. In a telecom or industrial cabinet where the connector is reconnected quarterly, that's over a century of service at the contact interface.
Right-Angle Through-Hole — Board-Edge Routing
The contact length after the bend is 0.114" (2.90 mm) — enough to clear a standard 1.6 mm board and still leave a visible solder fillet on the bottom side.
It is still in the manufacturer's catalog and available through normal distribution.
