5 IC's is not going to trigger anything. That's a flea fart. Lastest time, I had qty. 20 (all they had in stock) DSP about $1,000 in the cart, and gone in the hour.
You might need a little crash course on double-blind studies and how easily we can fool ourselves by single-sided unblinded experiments and anecdotes.
The idea that you notice chips going out of stock
during a chip shortage, and leap to the assumption that it's because of the state of your cart just because of a coincidence on the order of hours... rather than because there's a chip shortage... let's just say "extraordinary claims require extraordinary evidence".
I've seen TQFP ATMEGA32U4's and MA12070Ps go out of stock while I had them sitting in my cart (only single digit quantities, "a flea fart" as you would put it). Some other parts that I shortlisted but never added to my cart went out of stock too. So, in short:
"flea farts" in cart: not going out of stock (cortex_m0)
"flea farts" in cart: going out of stock (rs20)
"flea farts" not in cart: not going out of stock (rs20)
"flea farts" not in cart: going out of stock (rs20)
"1k order" in cart: not going out of stock (rsjsouza)
"1k order" in cart: going out of stock (floobydust)
Looks a lot more consistent with "good single-vendor parts don't stay in stock very long these days and pretty regularly/randomly go out of stock" than "the bad men are snooping on floobydust's shopping cart"
It might be fun to do a proper test though. Lots of parts, and privately held "control carts" to see the background rate of things going out of stock outside our carts so that we can then actually compare that to the rate of things going out of stock within our carts.
(Also, isn't the fact that the distributor
only had 20 left in stock of your DSP IC enough of a hint to scalpers? I'd have thought that's a far better signal and also way less tin-foil-hat of a theory that the 'everyone's snooping on floobydust's cart' theory)
