Product details

The 77311-118-10LF: The 10-position single-row layout keeps the board footprint narrow, and the 0.230" (5.84mm) mating pin length gives enough reach to engage a receptacle's contact beams without bottoming out.

The housing carries UL94 V-0 flammability rating, which satisfies the enclosure fire-safety requirement for most commercial and industrial equipment.

The 77311-118-10LF is one of several position variants in the BERGSTIK® unshrouded header family. The closest sibling is the 77311-118-16LF with 16 positions — same pitch, same 0.450" overall pin length, same gold mating finish. The choice comes down to the number of signal lines the board needs.

The post side is tin-plated (78.7µin), which solders reliably to the board. Phosphor bronze base metal gives good spring retention over the temperature range.

Frequently asked questions

Is 77311-118-10LF compatible with standard 2.54mm IDC connectors?

Yes. The unshrouded header leaves the pins exposed, so the mating half must provide its own polarisation.

What is the closest alternative to 77311-118-10LF if I need more positions?

The 77311-118-16LF is the 16-position sibling — same pitch, same gold finish, same overall pin length. If you need fewer circuits, the 8-position (77311-118-08LF) or 7-position (77311-118-07LF) share the identical footprint and ratings.
