Does anyone have any information on or remember the old EEM product category numbers (i.e. 1500 for capacitors, 1800 for inductors, etc.) It was in an old edition of books from a few years ago and I no longer have them. Hearst does not offer these on their web page any longer or in the new editions. I used these numbers to create part numbers before and need to add some new ones using these codes but no longer have them.  
 
Any help would be greatly appreciated.
