The single-position count makes this part a breakaway segment from a longer strip — you get exactly one pin, not a multi-row header.
In a low-cycle application (a few dozen matings over the product life), this is adequate; for frequent disconnect/reconnect, the thin layer will wear through faster than a thicker gold plate. The post finish is tin at 118.1 µinch (3.00 µm), which solders cleanly into the plated through-hole.
It is RoHS compliant.
How It Compares to Similar Headers
The 826629-1 is unshrouded, single-position, and gold-flashed — a different tool for a different job: one-off signal or power tap versus a multi-wire harness connection.
