Wow, I am pretty sure I had some of these, parasitic power would NOT work, I had it on a scope and everything. What a pain in the butt that was! Why not just give these mostly cloned parts their own honest name and part number?
Would you have bought it, at the same price, if they had?
This affects temperature sensors/parts bought from un-official distributors like ebay or AliExpress, not digikey, farnel, etc. Perhaps I've been too lucky in my career and practiced EE for work, but who would you ever go to ebay instead of digikey?? Digikey certainly has a premium, but their speciality is small numbers/cut tape/etc and they have a small order size which makes them ok for hobby work, and I've used the…
So much stuff on eBay is free shipping, that's huge when you only need a few dollars worth of stuff. If I could convince Digi-Key to lick a 55-cent stamp when I need ten of something, instead of charging me $7 for shipping, I'd have a lot fewer counterfeit parts around.

Another professional EE here. I never expect random chips bought off AliExpress/eBay/Amazon/etc to work, much less be genuine. I do expect breakout modules and the like to work, though I don't expect them to contain genuine parts. (That implies I'd never source from these places when it's a critical function.) I'm always surprised when people expect grey-market crud to perform just as well as top-dollar stuff....
I'm Canadian, and last I checked, the shipping costs to get parts from places like digikey was just ridiculous.
Anyone have an idea what these are used in? I originally thought they might be used for 3D printing, but that doesn’t seem to be the case - except, perhaps for chamber temperature.

I've bought hundreds of electronic parts on eBay and rarely had issues. I discovered LED strips were a thing by shopping on eBay, years ago, much before they were trendy, I was buying them at one fifth the cost American retailers were charging. Bought Arduino clones for a quarter the price of the "real" thing when I was a broke student. ATMega MCUs for a dollar a piece, free shipping. They worked perfectly fine. Coul…
In professional engineering, where time is money, Digi-Key or Mouser is always more efficient, if they've got what you need. For personal stuff, where the value of your time is ~zero, the opposite can be true.

If I were working on something more important that dinking around for fun, sure, I might care a bit more about what's actually on the board. But as it is, the clones are more than adequate for my needs, particularly at their price point.
