Product details

What This 2-Pin BergStik Header Is

The 77311-118-02: The post finish is tin-lead at 150.0 µinch (3.81 µm), which solders cleanly into a plated through-hole.

Obsolete — Sourcing Reality for the BOM Line

Available through independent distribution channels on a lot-specific basis. If you are filling a BOM line and need a drop-in replacement, the closest match is another 2-position, 0.100" pitch unshrouded header from the BergStik family with the same mating pin length (0.230") and overall length (0.450"). Confirm the contact finish and post length against your solder process before committing.

Mating Fit and Termination Checklist

The tin-lead post finish is compatible with SnPb and SAC solder processes, though lead-free profiles may require a higher peak temperature to wet the post reliably.

Frequently asked questions

Is 77311-118-02 obsolete and what is the replacement?

Yes, the 77311-118-02 is marked Obsolete by Amphenol ICC (FCI). No official replacement part number has been issued. A functionally equivalent 2-position, 0.100" pitch unshrouded header from the same BergStik series can be sourced — verify the mating pin length (0.230") and overall length (0.450") match your board stack-up. Availability is lot-specific through independent channels; confirm at RFQ.
