Shelf life guidance needed for QH03TZ600

2 posts / 0 new

Re:  Part number QH03TZ600.  I have been informed that PI recommends testing for all functions plus evaluation of solderability for parts with date codes exceeding two years.  I am trying to solve a production problem for our factory but this "requirement" is delaying a solution by using parts from Digikey or Mouser that I am told exceed two years.  What is the official position of PI on date codes that exceed two years?  

Hi jfryslpe,


Power Integrations has an internal policy of requalifying parts stored >2 yrs.  There is no stated policy regarding our customers' inventories, so our advice is for you to proceed with assembly, and if no issues arise, it should be ok.
