I strongly against counterfeiting & never promoted unreliable sources in my life. If you read my old posts or threads you will find that. I just enjoy what i do, i like to find gold from trash. I keep used genuine parts from various so i can use them later & so far I'm good.
Edit- greed is in human nature, you just can't avoid that in many form.

And what happens to the production waste? I got a 14 pin free sample opamp with an inverted and manually corrected notch...
It is production waste for a reason. Those parts will be handled by the next person as normal parts, so by using them you are creating time and parts waste for the next person.
Production waste is waste. It is garbage, throw it out. They were supposed to destroy it by the way.
And it works and they ship it as a free sample. I don't know if they also ship batches of samples that aren't exactly compliant...
I can't ever remember getting a sample that was not, as far as I could tell, in perfect shape. Samples are typically sent from the same stock used when buying directly from the vendor and those parts are far, far more likely to go to a larger customer so would be certain to be normal "prime" components. There are a lot of people that seem to like to try and save a little bit using second or third sources (or, God forbid, Chinesium) but that is a sure way to have problems sooner rather than later. Spend the money with either the OEM or a mainstream vendor and eliminate a huge source of potential issues.
Absolutely!!!
How can a substandard "sample" be of any commercial use, or a good advertisement of our product ????
My bet is that those kinds of samples were stolen and marketed. Any fab I have heard of recently destroys any rejects. Typically with early North American companies, substandard parts were marked with a number with much lower specifications. Some replacement semiconductor companies (I didn't single out ECG) bought the garbage and sold them for massive profits.
Any FAB that doesn't destroy substandard lots can't be trusted for anything, and certainly their business office is being extremely short sighted.

My company destroys test rejects, so they don't get stolen, re-marked and passed off as legitimate product. It's sad that there's such a big market for counterfeit products - anything to turn a few pennies.
I can get these transistors at a local store very cheaply. They would be ideal for an amplifier that has MJ15003/04 in it. I wouldn't say they are fakes, I just don't know who the manufacturer is? They still have a smaller quantity in stock, which is probably why the price is low.

You can cut open one & see how the die looks like inside. Yes, you can use these instead of MJ15003/4.
The 15024/5 have lower gain linearity than the 15003/4. You are better off with the 21195/6. They are a closer match.
Who knows, I have two pieces, the one with 15024/25 sounds better. The power supply is +-60V, so the 15022/23 also fit. Just to replace the output transistors in this older one. There are original Motorola 15003/04 with Aluminum caps.
