Product details

22-Position Dual-Row Receptacle for Mezzanine Stacking

The 71991-411LF is a 22-position, dual-row receptacle from Amphenol ICC's Dubox series. The mated stack height is 11.04mm, which sets the board-to-board spacing when paired with a matching Dubox header. The receptacle accepts bottom or top entry mating, giving flexibility in board stacking orientation.

Tin-Plated Contacts and Termination Details

This is a heavier tin deposit than typical flash tin — it provides decent wear for moderate mating cycles (50-100) and resists corrosion in industrial environments without the cost of gold. The contact length on the post side is 0.118" (3.00mm) — enough for a through-hole solder joint on a standard 1.6mm PCB. Termination is solder only — no press-fit option. The connector ships in a tube, which is typical for through-hole parts that need hand or wave soldering.

Frequently asked questions

What is the mating header for the 71991-411LF?

The 71991-411LF is a Dubox series receptacle. It mates with a Dubox series header of the same pitch (0.100" / 2.54mm) and row count (dual-row, 22 positions). The mated stack height is 11.04mm. Confirm the header's post length and orientation to match your board spacing.

Is the 71991-411LF RoHS compliant?

The part number carries the 'LF' suffix, which indicates lead-free and RoHS-compliant plating — standard for current Amphenol ICC production.
