If you find yourself with some Cisco IR809G and probably other Cisco IR800-series industrial integrated services routers from eBay, you probably find yourself needing the DC power plug/connector. It took me a while to find these as the Cisco part number is useless in the 3rd party world.
Mouser lists them as “Pluggable Terminal Blocks 3.81mm euro plug 4 position” made by Molex, Mouser P/N 538-39519-0007. Which is where I got mine for a $2.38 as of 2024. I guess the pin pitch is the important thing. I was only familiar with 5/5.08mm Phoenix connectors where there was no septum thingy between pins, whereas 3.5/3.81mm the pins are enclosed individually. Also TIL Phoenix and Europlug and Euroblock connectors are all the same thing depending who you ask and who makes them.
Radwell lists them as the 29-6115-01-A0 for $16, ooof. Which is still better than the dude I saw selling them on eBay for $45.00 each!
