05:59 AM exp: I really want to understand where the secret parts bin is that some suppliers seem to reach into
06:07 AM exp: I've got a series of backorders stretching out till september next year for a common Ti hotswap controller
06:07 AM exp: been sat like this for weeks with most popular suppliers
06:07 AM exp: but out of nowhere i checked RS components, who for whatever reason showed very short lead times
06:07 AM exp: and.. the parts actually arrived, despite them being impossible to get anywhere for a year
06:42 AM twnqx: backorders getting fullfilled all the tiem
06:43 AM twnqx: i was scraping through all of europe for one particular part, and within a week i maneged to procure at least 1600, it batches between 75 and 930...
06:43 AM twnqx: (don't ask for the cost explosion though...)
07:36 AM specing_ is now known as specing
07:59 AM qu1j0t3: exp: yeah that is probably literally what's happening. i've seen mysterious changes to digikey stock levels i.e. down to a dozen on a part with a lead time then a day later up to 100. that's show business baby
08:00 AM qu1j0t3: there's no reason to believe stock levels shown are actual stock levels...
08:14 AM exp: twnqx: it's the inconsistency of it that shocked me, one rnadom UK supplier beats everyone else by 9mo+
08:15 AM exp: qu1j0t3: yes i almost pulled teh trigger on 1000 LM5050MK-2/NOPBs and then about a minute later they went down from 15000 to 0
08:15 AM twnqx: well, i purchased my part from RS
08:15 AM exp: no idea if stocking or some other lucky bugger
08:15 AM exp: twnqx: same :)
08:15 AM twnqx: apparently they get a reel every month or so
08:15 AM exp: twnqx: they also shipped me a bunch of 160 ohm resistors labelled 160K
08:15 AM exp: RS-quality :)
08:15 AM twnqx: i got 940 from some random italian company noone ever heard of
08:15 AM twnqx: 100 from austria
08:16 AM twnqx: 300-something from some pan-eiropean compay, not sure where tehy are headquarterd
08:16 AM exp: i'm down to basically one part i need now
08:16 AM exp: and it's a DCDC controller
08:16 AM exp: so i do have some alternatives there
08:16 AM twnqx: but hey, randomly, arrow got us another 1000 this week
08:16 AM exp: currently fighting with technicians who are trying to make mountains out of molehills
08:17 AM twnqx: from a 4000 pieces order we places last year november, due last august, announced for january
08:17 AM exp: ouch
08:17 AM twnqx: suddenly: 1000 pieces arrive
08:17 AM twnqx: potentially even more!
08:17 AM exp: i'm looking forward to that with a few bits
08:17 AM twnqx: oh, and i think 250 randomly showed up at digikey
08:17 AM exp: TPS274160
08:17 AM exp: i'd really like if someone found 50 of those please :)
08:18 AM twnqx: i bet i can find those, but you won't like the price
08:18 AM exp: the answer is just: back order everywhere and hope
08:18 AM exp: yeah probably
08:18 AM exp: I have some AD9548s in stock, those are ~£100 a unit from places now
08:18 AM exp: currently $170 in singles from win-source lol
08:18 AM twnqx: we bought 4000 TPS63020DSJR...
08:19 AM twnqx: at 6.71€ each...
08:19 AM exp: christ
08:19 AM twnqx: now look up what they cost new from anyone else
08:19 AM exp: i have a few hundred of the bigger brother version of that
08:19 AM exp: and yeah, zero stock anywhere
08:19 AM twnqx: we're trying to replace TI everywhere we can
08:20 AM exp: not sure who's in a better position
08:20 AM exp: most of our LDOs are now NCPs
08:20 AM twnqx: "fun" if have a system PMIC, voltage supervisor, and step-up from the
08:20 AM exp: but lead times stretching on those too
08:20 AM exp: i don't have an alternative for UCC29002s from them
08:20 AM exp: there's only a couple of other people who make these integrated controllers
08:20 AM exp: and i don't fancy bodging up my own
08:21 AM twnqx: maxim might have something like that
08:21 AM twnqx: and diodes inc
08:22 AM twnqx: for your tps... ask info@ic-direct.com - expensive, but they deliver
08:22 AM twnqx: (it's where we got our 7€ ICs...)
08:23 AM twnqx: or they tell you "sorry, no dice"
08:23 AM twnqx: but if you need a few thousand miron 3GB automotive emmcs, let me know :P
08:23 AM twnqx: i now have 4040 extras.
08:24 AM twnqx: fun way to spend 80 grand
08:27 AM twnqx: by the way, utsource seems really a mixed bag of fake and not fake
08:27 AM twnqx: at least the most expensive chip i bought there was not fake
08:28 AM twnqx: the v20/v30 are like always fake
08:28 AM twnqx: *sigh*
08:28 AM twnqx: i really hope my friend in tokyo gets some local NOS for me :X
08:30 AM twnqx: TPS related: https://www.digitimes.com/news/a20211111PD200.html (headline is enough)
08:45 AM exp: twnqx: sorry i had to run, i will go through those in a second
08:45 AM exp: thank you very much!
