The 77311-401-26LF is sourced through independent distribution. No stock-holding claim is made — each order is sourced per your BOM.
The mating pitch is 0.100" (2.54 mm) — a standard spacing that matches most 0.100"-pitch IDC sockets and through-hole receptacles.
It is unshrouded — no plastic shroud around the pins. This means the pins are exposed for direct mating with a receptacle or socket that provides its own alignment.
For a pin-compatible alternative within the BERGSTIK® series, compare the pitch, position count, and post length against other 0.100" single-row headers from Amphenol ICC (FCI).
