It uses a standard 0.100" (2.54mm) pitch with matching 0.100" row spacing, making it footprint-compatible with a wide range of IDC receptacles and socket strips.
The 0.100" pitch and 0.100" row spacing match the industry-standard 2.54mm grid — the same footprint used by legacy BergStik and competing.100" box headers. That means the board layout transfers cleanly if you swap between suppliers. The 46 positions are fully loaded (no skipped pins), so the BOM position count must match exactly. For a board-to-board header that gets mated once in the build and stays, that is more plating than needed — but if the board pair is field-swapped or reworked, the gold pays for itself in contact resistance stability.
For a BOM line that needs 46 positions at 0.100" pitch, this is a standard, widely available part with no single-vendor lock.
