The guide is drafted with specifications, wiring guidance, alternatives, and sourcing links. I’m checking the citations and clarifying the distinction between mating-plug dimensions and the jack’s own dimensions; the terminal-number assignment remains unverified.

Created the PJ-037A Application and Usage Guide in project files, covering all seven requested sections with manufacturer citations and sourcing links.

Terminal-number assignments, exact footprint geometry, and some alternative specifications remain explicitly unverified; no replacement is claimed as drop-in compatible. Before design release, verify center/sleeve continuity and compare the footprint against the manufacturer drawing.
