The Amphenol 68022-170HLF is a 70-position, dual-row unshrouded header from the BERGSTIK® II series, built for board-to-board stacking with a standard 0.100" (2.54mm) pitch. It carries square male pins with 30.0µin (0.76µm) gold or Gold GXT™ plating on the mating surface — thick enough for repeated mating cycles and field service without corrosion concerns. Rated 5A per contact at 110V, it handles moderate power distribution alongside signal duty, though the 70-position count means total current across the header sums to 350A — that's a bus-level number, so the board trace and connector derating curve need a look if you're loading more than a few circuits at full current.
The 30.0µin gold plating is the real differentiator here: that's not a flash coat for one-time assembly, it's a field-grade thickness that survives 100+ mating cycles in a corrosive or humid environment. The 5A per contact rating is conservative at 25°C, but the UL94 V-0 housing limits the temperature rise — if you're running this in a 85°C cabinet, derate per the manufacturer's curve.
This is an unshrouded header — push-pull mating, no latch or keying. It mates with any standard 0.100" pitch dual-row receptacle housing that accepts square 0.025" pins. The through-hole solder tails are 0.110" (2.79mm) long, sized for standard 0.062" PCBs. The contact length on the mating side is 0.318" (8.08mm), which gives good wipe before the pin bottoms out.
No official cross-reference or direct replacement exists in the BERGSTIK II family for this exact 70-position, right-angle variant — the 68022 base number covers a range of position counts and orientations, so confirm the BOM line against the 70-position, right-angle spec before committing.
