smt component id | 7 December, 1997

part of my job is to id and source electronic components. i have an ongoing problem iding smt devices w/mfr codes in place of actual part numbers does a cross ref guide exist that will enable me to id a smt transistor(eg)by the marking codes on the device. some are easy to id. others have mfr 2 or 3 digit codes same holds for many smt devices. need help ! thanks

Please check the Chip Directory. Link to it is available from the bottom of the SMTnet home page, under Other Sites. Good luck, Cunli

Another good source I've come to use quite often is the search engine from National Semi-Conductor. The link to the page is down below. If you ever run into a situation where you only know the company of manufacture for the chip, go to their web site, most will have a comprehensive list of every component they keep in stock w/PDF files for finding out specific characteristics of the components. Good Luck -Ben

It is also my job to ID and cross components. I have found that the same number can be used by different manufacturers for different parts, same package style. There is not a standard marking system for SMT devices so watch out for this.
