REF31-Q1: Ordering and Quantity Information

Part Number: REF31-Q1
Other Parts Discussed in Thread: REF3133

Tool/software:

Hi,

I was wondering what the Suffix highlighted in bold meant for the following serial numbers : 

I've obtained the following information from your website/ component datasheet:

  • DBZ is the package type
  • T/R: Tape/Reel
  • Q1: AEC-Q100 Qualified. 

But I am unable to find any information on the AQ/AI suffix in the part numbers, is this suffix used to identify a difference between the devices and if so what is the difference between the two? 

Thanks in advance, 

Josh
