The 2842127-3: The 2.00 mm pitch on this 6-position, dual-row header sets the board footprint tighter than the legacy 2.54 mm standard — useful when routing traces between pads on a dense PCB.
Peer Comparison: 1376779-2
The 1376779-2 also carries a thinner 8.00 µinch gold mating finish versus 15.0 µinch here — the thicker gold on the 2842127-3 gives it an edge in mating cycle life for field-service applications.
