The 1-2314843-6: The dual-row layout with 0.079" row spacing keeps the board area tight for a 16-circuit interconnect. The connector accepts either bottom or top entry, which gives the board designer flexibility in stack-up height and routing — a practical advantage over single-entry parts.
Tin Mating Finish at 118.1 µinch — What That Means for Cycle Life
That's a thick tin layer — well beyond the standard flash tin (typically 30–50 µinch). If the design calls for frequent reconnection (field-service or modular boards), a gold-plated sibling would offer higher cycle life.
Comparing Against a Sibling — 1-2823056-2
The 1-2314843-6 offers a tighter 2.00 mm pitch and 16 circuits — better for dense board layouts. The 1-2823056-2 uses a forked contact shape and a polyamide housing; the 1-2314843-6 uses square contacts and an LCP housing rated UL94 V-0. Choose the 2.00 mm part when board area is constrained; the 2.54 mm part when legacy spacing or higher voltage (100 V vs 125 V) is needed.
