I have some Intersil ISL5729/2IN components I am trying to decode the part marking , Lot Date Code and Assembly site,
The marking on the component is as follows:
Does anybody know how to decode the P731BT5 code?
P is the factory location code, 731 is the date code (parts were built the 31st week of 2007) and BT5 is a trace code. All 7 make up the complete trace code which identifies the manufacturing lot the parts…

Hi, Thanks for the info, I was able to find the other codes from PCN's mostly written by Jon Brewster online. Is it possible for you to tell me if that complete trace code, "P731BT5" is a real code that matches product produced by Intersil in the past?
this part has been obsolete since October 2011, it is not available from any authorized distributor that I can find. If you have any for sale, please let me know...

I understand, I have been working this issue for several weeks. and I am familiar with the issues of procuring components outside of the OEM authorized distribution network. I also understand OEM reluctance to assist in any broker part authentication activities. My company does not purchase broker parts, however we have 3rd tier suppliers that do. I also know that Intersil is a fan favorite supplier for counterfeiters due to the unique nature of the products and lack of interchangeability. There is a paper written by Yong Hong in the 2011 ISTFA proceedings I think you would be very interested in.
