TVP5150AM1: Can i know difference between marking 5150I & 5150Q

Part Number: TVP5150AM1

Dear Support,

We recently purchased PN# TVP5150AM1IPBS from Arrow Electronic but received different device marking per TI's datasheet.


> Device marking is 5150I

> Received, Device marking is 5150Q

Based on data sheet, device marking for 5150Q is for PN# TVP5150AM1IPBSQ1

I also found out Q1 is for Qualified for Automotive Applications (AEC-Q100 Rev G – TVP5150AM1IPBSQ1) from the data sheet.

But i cannot define difference between 5150I and 5150Q....

Could you please explain if TVP5150AM1IPBS and TVP5150AM1IPBSQ1 are same part?

If not, could you explain details about the difference?
