It uses a 0.100" (2.54 mm) pitch on both rows and contacts, making it a standard footprint for prototyping or production boards that need a modular pin strip.
Rated 5 A per contact, the 75844-156-14LF handles moderate signal and low-power duty — enough for logic-level supply or I/O lines, but not for a main power rail. The gold GXT™ plating on the mating surface (30.0 µin / 0.76 µm thick) gives it good corrosion resistance and a higher mating cycle life than a tin-plated equivalent, which matters if the board sees repeated rework or field service. The 110 V voltage rating and UL94 V-0 thermoplastic insulation (black) are standard for equipment inside an enclosure.
