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:
"I logo"
ISL5729
/2IN
P731BT5
Does anybody know how to decode the P731BT5 code?
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?
Please Submit a Technical Support Inquiry You will need to provide proof of purchase from one of our authorized distributors. Otherwise we cannot provide the information you are requesting.
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...
Rochester Electronics is our only authorized distributor of our obsolete parts and their website is not showing they have any remaining stock. We (Intersil - now part of Renesas) do not stock this part.
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.
