Kuramochi-san,
Here is some additional background.
The TPS25810-Q1 is the original released device for Type-C port control.
The TPS25810A-Q1 was a minor change from TPS25810-Q1.
Hope this helps.

John-san,
Thank you for your information.
My inquiry was unclear, I'm sorry.
The customer would like to know if TPS25810-Q1 and TPS25810A-Q1 are same tendency on the reliability.
They have tested TPS25810-Q1 and confirmed what it is no problem on reliability.
And they hope what TPS25810A-Q1 test result is same with TPS25810-Q1.
I asked chip difference because I think that reliability is almost same if chips is similar.
Needless to say, they will test actually.
They are requiring this for their reference.
Best Regards,

Kuramochi-san,
The reliability should be identical. They share the same base chip.

John
