The 1-794074-1: This is a 14-circuit, 2-row vertical header from TE's Mini-Universal MATE-N-LOK series, on a 4.14mm pitch — a common footprint for wire-to-board power and signal interconnects in industrial controls, appliances, and general-purpose equipment.
The 4.14mm pitch and 0.163" row spacing define the PCB hole pattern: 14 through-hole solder tails in two rows, each post 0.175" long. Confirm your board layout matches these centers before committing the BOM line.
Mating contacts are gold-plated at 30.0µin, with tin-plated solder tails at 150.0µin. At the board side, the solder joint and trace width set the practical limit.
