29 Positions at 0.100" Pitch — Single-Row Footprint
The 68685-329LF: That pitch and row count set the PCB footprint: 29 through-hole solder tails in a single row, with a 0.115" (2.92mm) post length for board thickness up to ~1.6mm.
1000V Rating and 30µinch Gold Mating Finish
Voltage rating is 1000V, which is well above typical 2.54mm-pitch signal connectors — the PPS insulation and contact spacing support industrial isolation or telecom line-voltage applications. For a board that gets swapped quarterly, that translates to decades of reliable contact.
The connector also meets RoHS compliance (LF suffix).
