DP83848Q-Q1: Need to confirm if we could use the DP83848T and DP83848H as possible alternate

Part Number: DP83848Q-Q1
Other Parts Discussed in Thread: DP83848T, DP83848H


Good day.
Our customer has a question about the possible alternate for DP83848QSQ/NOPB. Kindly see below.

I am currently using the DP83848QSQ/NOPB ethernet phy chip, but due to stock issues going on I am planning to use a different part. I found this part which seems like a perfect fit DP83848HSQ/NOPB and DP83848TSQ/NOPB (it has the same pinouts and register mapping from what I saw). Could you confirm if this part can indeed be a drop in replacement for DP83848QSQ/NOPB?

Thank you.



  • Hi Cedrick, 

    Does the customer need an automotive grade part? The DP83848Q-Q1 is AEC-Q100 Grade 2 certified, while the DP83848T and DP83848H are not. 

    Otherwise, the parts you listed can all be drop in replacements for each other.
