Product details

5-Pin BERGSTIK Header — Unshrouded, 0.100" Pitch

The 77311-122-05: The tail length is short enough for single-sided boards but may not reach through thick backplanes or boards with heavy copper pours.

Obsolete — Sourcing and Replacement Options

The base product number is 77311, which covers a family of unshrouded single-row headers with various pin counts and plating options. A buyer looking for a functional replacement should search for a 5-position, 0.100" pitch, unshrouded header with a gold mating finish from any major manufacturer, then verify the board footprint (pin length, tail length, and insulation height) against the existing layout.

The insulation color is black, which is standard for the series.
