I’ll research the manufacturer’s documentation for 691137710004 and write a cited application guide, including wiring, PCB layout, alternatives, and sourcing.
The datasheet specifies −30 to +110 °C and a PA6/66 housing, which differ from the project description. I’ll use those verified values and flag the unresolved footprint dimensions and replacement compatibility.
The Würth Elektronik 691137710004 is a four-position, 5.00 mm-pitch WR-TBL Series 1377 PCB terminal block with horizontal wire entry and screw-operated wire protectors. It provides a practical through-hole wire-to-board interface for power and low-frequency field wiring in industrial control equipment; terminal functions are assigned by the application, not by the connector.

Created the cited 691137710004 Application and Usage Guide in project files, covering all seven requested sections and authoritative sources. The guide uses verified datasheet values, flags unresolved footprint details, and clearly labels both alternatives as functionally similar—not verified drop-in replacements.
