And what about the pinout? What about the resistance/watt? What about the thermal sensor?TIA

content: They look similar to the QUICK TS1200A tips.Heater resistance is similar, so you have nothing to lose by trying out.The worst thing that could happen is a burned T12 tip if the TC curve is very different.

I recommend you purchase separate solder iron and have two irons, one for stock WQ tips and one for T12 tips. Here are instruction on foreign language --http://kodabra.ru/all/aoyue-2702-i-hakko-t12/Basically google translate.The real golden piece of information is contained within this commend.Basically you would have to fiddle with contact, so that they are touching proper parts of T12 tips. It's no problem, remove them, and place them where they would touch -- there are several places where you can place them.WARNING: order a new iron and modify it, leave your original iron alone. WQ tips are nicer, they are shorter and easier to use, and they are of better quality. But, for a price of 1 WQ tip you could buy 15 el cheapo T12 tips on aliexpress.

I do not think aoyue tip deserve 12 euro each ....I think also you are right about buying another iron .. I have anyway 4-5 tips from aoyue, they work fine, so I still want to use them and keep an iron the way it is now.And, regarding the 2 pin / 3 pin discussion ... my 2702 works clearly also with tip with two contact. I have one aoyue tip with 2 contact only ..... so, it can manage both type of tips. But now I wonder how he keep temperature under control ...

So if 2 contact aoyue tip works with your iron, then chances are no mods will be required. As far as 3 contacts, I think they made it because of legal issues so that it wouldn't be that readily compatible with Hakko. Legal issues plus monetary issues, selling tips are money.Now I did disassemble my iron. There are 5 wires, 1 and 2 are together, 3 and 4 are together, and 1 green one just connects to chassis inside station. So thermal resistor most likely is in series.Here, I ordered tips real cheap, shipping is about 20 days. Try it, if need to mod iron, then get a new ironhttps://aliexpress.ru/item/1005005971901133.htmlI also seen aoyue iron on aliexpress, about 20 bucks.You could also get a T12 iron instead of aoyue iron. But then there would be issues with stand and I think aoyue has a quality iron.On a side note, lately I've been seeing aoyue stations like mine and yours being for sale real cheap on free ads sites. You can buy a used station for about 50 bucks. Technology is getting old. Even smallest tip is not small enough. There are better stations today. Pretty much everyone upgraded their Hakkos, Louis Rossmann, iPad Rehab, STS Telecom, and other youtubers. T12 is rarely seen in repair videos these days.
