Are these MB510 ICs fake?

Why would they go through the trouble of renumbering one IC into other and sell it?

Because they can sell one thing as another and earn some money by doing so. That's how counterfeiting business works. Were you born yesterday?

Because it's possible to turn a pile of worthless obsolete parts into rare ICs that can be sold for several dollars each. Is it not obvious?

At least the GND/VCC/OUT pins appear to match a real MB510 ;) What about others - are some of them NC though they shouldn't, is the NC truly NC?

Yeah I'll stick one on a piece of copperclad and see what happens with the test circuit. I haven't checked the NC pins yet but I'll look at it after work.
