content: That is outrageous.. I don't understand how this scam could possibly pay back. Maybe we can keep a list of trusted eBay suppliers for NOS stuff which is not available through standard suppliers, although of course it could get infiltrated by scammers.

content: I had exactly the same thing happen. Seller then had the gall to ask If I needed NPN transistors instead of returning them.

content: Possibly we could have a board where we put up bogus devices and their sellers.I am unable to even unable to give the seller a bad review because somehow they switched my ID to one I hac never heard of and I cannot sign in. The FETs do not even appear on my purchased list!!Apparently the e bay reviews are useless.I know there is on unhappy shopping experience place but maybe we could be more specific as to fake parts.

content: I ordered some MMBFJ310 from aliexpress. And guess what: I got NJFET with at least data that correlates to the J310 and it works in my amplifier. Seller washttps://www.aliexpress.com/store/1523448May order again as OnSemi indicates "Last order" on that part.
