I have a board house that I've tried doing exactly that with simple passives, and it's always a mess. The last BOM specified "1k ohm 5% tolerance or better, 0805 size resistor - any manufacturer" and it resulted in three calls from them asking if XX was acceptable and eventually them wanting me to authorize it in writing. Turned into a bit of a fight and eventually they claimed that they "have to have a MFG part number, it's part of their ISO requirements". --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
