Board footprint and circuit count
The 794072-1: This is a 24-position, dual-row header on 4.14 mm pitch — the board footprint matches the Mini-Universal MATE-N-LOK receptacle family. The row spacing is also 4.14 mm, so the pin field is a uniform grid that routes cleanly between power and signal traces on a standard 2-layer board.
Voltage and temperature rating
The 600 VAC rating is the dielectric withstand between adjacent circuits at the rated altitude — in a 480 VAC panel, this header gives margin. The -20°C low end covers unheated storage; the 85°C ceiling is typical for equipment inside an enclosure with moderate internal heat rise.
Peer comparison: 4-1775099-7
The closest functional alternative is TE 4-1775099-7, a 20-position header on 4.20 mm pitch with tin plating (120.0 µin) and square contacts. The 794072-1 offers 24 positions on 4.14 mm pitch with circular contacts and tin-lead plating — the pitch difference is 0.06 mm, which matters for the mating receptacle's contact spacing. The 4-1775099-7 carries a 9 A current rating vs the 794072-1's current rating that varies by wire gauge.
