5.00 mm pitch, 15 A — the power-handling boundary for a 4-position header
The 796864-4 is a 4-position right-angle shrouded header from the TE Buchanan series, designed for terminal block applications where a plug mates into a fixed header on the PCB. The 0.197" (5.00mm) pitch sets the board footprint and the per-contact current ceiling — at 15 A the temperature rise stays within the UL94 V-0 polyamide housing's limits. The 300 V rating covers most industrial control and power distribution circuits.
Tin-plated contacts, 8.36 mm insulation height — board-fit checklist
The insulation height of 0.329" (8.36mm) provides clearance above the PCB for wire entry into the mating plug. The 0.138" (3.50mm) contact tail length is standard for through-hole soldering into a 1.6 mm thick PCB. No special tools beyond a soldering iron are required for mounting. The mating flange feature provides additional mechanical retention when the plug is screwed down.
