It uses a 0.100" (2.54mm) pitch on both rows and contacts, matching the standard 0.100" grid for straightforward PCB layout.
Contact Plating and Duty
The solder tails are tin-plated, which is standard for through-hole wave-solder processes. The 5A per-contact rating is per individual pin; for a 50-position header, the total current capacity depends on how many circuits are active and the ambient temperature, but the contact itself is not the limiting factor at moderate loads.
Mounting and Mechanical Fit
Right-angle through-hole termination with a 0.120" (3.05mm) post length and a 0.160" (4.06mm) mating pin length. The insulation height is 0.190" (4.83mm) above the board.
