Mark code different

[man]

Hello,

Received the parts IRS2011STRPBF. All the package type is SO8N. 

But we found out two of kinds marking code. (S2011S vs S2011). Why are they different mark code? Have any PCN to support?

Please see the attached photo. 

Thanks

Hi man，

I checked with my production line colleagues.

Here is explanation as below:

At some point >10 years ago, the marking was changed from “S2011” to “S2011S”.  You have some older parts (>10 years old) which are marked as “S2011” and newer parts marked “S2011S”.

Best regards,

Rachel
