I do not believe they are as if I recall, the part numbers are different. You can cross reference this by using a parts site like InfinitiPartsOnline.com or something.
Now, that doesn't also mean that different part numbers = different parts but in my experience it does. For my wife's new 2016 QX60, there are 2 sensors who share the same part number and 2 others who have different part numbers.
Ok, so after long hours today I have found that the "faulty" o2 sensor indeed actually works, however the male connector harness for the driver side is somehow broken, the o2 sensor sometimes "works" and then decides to stop working
. I will keep updated if I find a fix to this w/o resoldering a whole new connector
