    How to handle manufacturer info in the library?


      In our library we are using the partnumber a the primary key. This is just a 'dumb' number like '1004473'.


      Every part in the library has, among others, the following properties to further identify the part;


      Part Name        : ELJPA220KF,  The actual part number from the manuacturer

      Manufacturer     : Panasonic,    The actual manufacturer of the part



      It sometimes happens that a manufacturer went broke, or merges with an other manufacturer making

      the above properties invalid.



      This means that we have to update all the involved  parts, or declare them obsolete and enter new parts as a replacement. In case of a

      manufacturer for resistors this is a awful lot of work.



      I am very interested how others are handling this issue.

          The easy answer is - don't.


          CAD systems aren't really designed to do a good job of maintaining a manufacturer list.  That's database kind of work.  Keep a separate database linking your part number to the approved manufacturer's numbers.  So if you need to change manufacturer information on the 1004473 part, you change it in your databse only, not in the 2 dozen schematics that use the part.  Depending on your software, you can push a BOM from the schematic, or pull manufacturer data into a BOM.  It's also a handy place to keep datasheets.
