You can use these spreadsheets to convert DC590+ part number formats.
Step 1 - Open the file below that corresponds to the first several characters of the UK/JDE part number you wish to convert. For example, if the part number begins "590-63", open the file named 590P-63 590P x-ref to 590+ 500-600V.xlsx
Step 2 - Edit the green shaded fields using the drop-down menus as per the part number you want to cross over. If prompted for a password the first time, it's ID10T. As you finish entering the part number, the US part number will populate in the yellow cells, along with useful notes.
