Product details

20 Positions at 0.100" Pitch — Standard Footprint for Prototyping and Production

This is a common choice for board-to-board stacking and cable-to-board connections where the cable-side connector already has a shroud.

Active Production — Stable BOM Line

This is a stable BOM line for both new builds and long-life equipment — no requalification risk from a sudden obsolescence notice.

Through-Hole Termination — Hand-Solder and Wave-Solder Ready

The square 0.025" pin cross-section provides a secure solder joint and good mechanical retention through the plated through-hole. The 0.450" (11.43 mm) overall contact length includes the mating pin and the solder post, giving a total board stand-off of about 0.100" (2.54 mm) from the PCB surface to the bottom of the insulator. The header ships in bulk packaging, which is typical for through-hole components — no tape-and-reel, so plan for hand-loading or tube feeding on the assembly line.

Frequently asked questions

How can I order the 77313-418-20LF and check availability?

The 77313-418-20LF is sourced through independent distribution. No stock-holding claim is made; availability is verified per inquiry.

What is the pitch of the 77313-418-20LF?

The pitch is 0.100" (2.54 mm) for both the pin spacing and the row spacing. This is the standard 0.100" grid, compatible with most 0.100" pitch receptacles and perfboards.

Is the 77313-418-20LF shrouded or unshrouded?

It is unshrouded — the pins are exposed with no plastic shroud around them.

What is the closest functional second-source to the 77313-418-20LF?

The 77313-818-20LF is a direct footprint and pin-count match (20 positions, 0.100" pitch, dual-row) but uses 15.0 µinch gold on the mating surface instead of tin. It is the same series, same dimensions, same current rating — the only difference is the plating grade, which extends mating cycle life.
