Interchangable rb25det neo thermostats

[nik.]

I was wondering if anyone could tell me if thermostats with different part numbers are perfectly interchangable as it doesn't make sense to me why Nissan would make different part numbers for the exact same item 

 

Specifically I am chasing a thermo for my rb25det neo part# 21200-V7205 or 21200-V7206 and I have found a seller with a part# 21200V720A suit patrol GQ/GC and he tells me they're the exact same and interchangable (they have the same operating temperature too). I would just buy the correct part# but the 21200V720A is nearly half the price and is a genuine Nissan item 

 

Can anyone please shed some light ?

Nissan changes the part numbers all the time because they change suppliers, they make minor revisions to cut cost or whatever reason. If you look up the 21200-V720A in the US parts catalogs they list that part as the superceding part number for 21200-V7206: https://www.nissanpartsdeal.com/parts/nissan-thermostat-asmy~21200-v720a.html

Same goes for Amayama actually, looking up both of those part numbers they list the V720A as the superceding part: https://www.amayama.com/en/part/nissan/21200v7206 and https://www.amayama.com/en/part/nissan/21200v7205

I have gotten a bad superceding part number from Amayama before with a replacement hose clamp not being the correct type to fit but I've yet to see any issues with the Nissan USA parts catalogs, those seem to be standardized a lot better. I have a lot of weird obsessions but I have never seen any reason to go for NOS of older part numbers, in my experience the OEMs care enough about supply chain integrity that I don't have to worry about it.

Exactly what I needed.

Thankyou!
