TPS53915: TPS53915RVER

Part Number: TPS53915

Hi experts,

The PCN# 20170804000C states a change in the material of the lead finish - NiPdAU (E4) and Matte Sn (E3) 

2 questions: 

a. Can customer used part# of both finishes inter-changably w/o making production line changes?


b. customer has been using the E4. Body marking does not show E4. However, the newly introduced Matte Sn (E3) finish shows a E3 marking on the body. Is there a PCN to show this marking inclusion?


Thanks in advanced.



  • Hi Shawn,

    Customers can use both finishes inter-changeably without any changes to the production line.
    The PDF you provided is the only PCN and does not mention the marking inclusion. However, you can differentiate between E4 and E3 by looking at the product shipping label.
