It uses a 0.100" (2.54 mm) pitch on both the mating interface and the row spacing — a standard footprint that matches the vast majority of 2.54 mm IDC ribbon-cable receptacles and through-hole prototyping grids.
Rated Duty and What It Means
That 5 A figure is typical for a signal-grade header at this pitch — it carries logic-level power and low-current I/O, not a bus rail. For a 30-position connector, the total aggregate current across all pins should be derated per the manufacturer's curve; running all 30 circuits at 5 A simultaneously would exceed the thermal budget of the single-row plastic body. For a board-to-board header that will see field service or multiple reconnections, the 30.0 µin gold is the right call. Tin-plated siblings would fret under vibration after fewer cycles.
Board Fit and Mating
The overall contact length is 0.730" (18.54 mm), and the mating pin length is 0.430" (10.92 mm) — that gives enough reach to mate with standard 0.100" pitch IDC receptacles and ribbon-cable sockets. Push-pull fastening — no latch, so the retention comes entirely from the contact interference fit. The 0.100" (2.54 mm) pitch and dual-row layout put this header on a very common footprint — it drops into a 0.100" x 0.100" grid.
