The 110 V rating gives enough headroom for most logic-level and low-voltage power rails inside an enclosure. Gold buys you 200+ mating cycles without fretting corrosion — worth the premium if the board sees repeated rework or the connector lives in a high-vibration environment where tin can cold-weld and wear through. For a one-and-done board stack, the tin-plated 75160-327-36LF does the same job at a lower BOM cost.
Dimensions and pinout — what you need for the board layout
The overall contact length is 0.465" (11.81mm), split into a 0.260" (6.60mm) mating pin and a 0.105" (2.67mm) solder tail. All 36 positions are loaded — no skipped pins. The single row at 0.100" pitch means the board footprint is a straight line of 36 plated through-holes on 2.54mm centres, with the first hole at whatever board-edge offset your layout allows. No shroud means no extra keep-out zone around the header body.
The pins are phosphor bronze — standard spring-grade material that holds up to insertion forces without taking a set. RoHS compliance is confirmed on the manufacturer's listing.
