Weatherstripping for Nissan

I need to replace the weather stripping around the door (rear, passenger side) of my 2015 Nissan sentra.

After phoning a few local Nissan dealerships, I was able to the get part/number. It is - 82830-3sg0a

Local dealers are charging $150-170 for it

I googled the part - Here are the places that carry the part and in stock

I noticed the part number is different
82830-3sg0a vs 828304af2a

According to this Nissan-USA website, the part number is 82830-4af2a
And supersession(s) includes the part number I was given for the weather strip for my particular vehicle which is 82830-3sg0a

My newb questions, what is supersessions? If the part number i was given is 82830-3sg0a then would the part 82830-4af2a still work for replacing the weather stripping around my rear passenger door? Any drawbacks to using the part 82830-4af2a instead of the specific one that the dealer provided?

I have also never ordered through these websites. Any risks like around customs or quality of parts or are they generally pretty safe to order from? Or are there better online alternatives to check instead?
