Product details

Board Fit and Footprint Considerations

The 77311-101-32LF: At 0.100" pitch, the 32-position single-row layout requires a board footprint of 3.20 inches (81.28 mm) across the pin row — each pin occupies 0.100" center-to-center. The 0.095" (2.41 mm) post length below the housing provides enough standoff for solder fillet inspection on a standard 0.062" PCB.

The base product number is 77311; the -101 suffix denotes the specific plating and post-length variant. No official pin-compatible replacement from Amphenol ICC (FCI) exists — this is the current production version.

The tin-plated posts are solderable with lead-free or leaded processes.

Frequently asked questions

Is 77311-101-32LF unshrouded or shrouded?

Unshrouded — the pins are exposed with no plastic shroud around them. This allows direct mating with standard 0.100" pitch receptacles and makes the pin row accessible for probing or manual wiring.

How many positions does the 77311-101-32LF header have?

32 positions in a single row, all loaded. The pin count matches 32-position IDC sockets and ribbon cable connectors.
