TPL5010: Replacement parts for TPL5010

Part Number:TPL5010

Hi,

We are using the TPL5010 as a WDT in our system, but the last few board spins we've done we've encountered issues with sourcing parts. Is this going EOL or being replaced by another part soon? I see there is the -Q1 version of this IC, but it's a little more expensive. 

Are there alternatives from TI we should look into?

Thanks,

Eric Myers
