Hello, i was working on a project that involoved a bc 547 transistor (a project i found on youtube), but because i didn't have a bc 547 transistor i went with a 2n2222, although i followed that schematics pricesly the project didn't work. After i looked up the bc 547 and 2n2222 datasheets i found out that the bc 547 is arranged as collecter-base-emitter but the 2n2222 is arranged as emitter-base-collector, and because there arent any near stores that sells bc 547 and i need to finish project quickly i want to find a solution to this problem quickly. Thanks

It seems in this case all you need to do to turn c-b-e into e-b-c is turn the thing round. :)
Got a link to the video?
Might be something subtle about it.
Many transistors will work upside down, with reduced specs, sometimes you never find out. :)

The specs of both are quite different, but if your application doesn't require something unique to either you'll probably get away with it after you've got the pins right.
