The 5-794619-2 is a 22-position, dual-row header from the Micro MATE-N-LOK series, on 3.00 mm pitch — the standard footprint for this wire-to-board family.

The closest peer in the same series is 1-1871673-2, a 4-position header at 2.50 mm pitch with tin-plated mating contacts. The 5-794619-2 carries 22 circuits versus 4, uses a wider 3.00 mm pitch, and has gold plating — a meaningful difference for higher-density board layouts and applications requiring more mating cycles.
