Only buy from authorized distributors.

And NEVER let purchasing make decisions about what to buy from who.

As JL said "Only buy from authorized distributors."

Appalling, disgusting, sad.

yes, but also a little misleading.

There are a few respectable resellers of end-of-life parts, like Converge.

They trace the parts history, and often do testing, to make sure they are authentic and good. Expect to pay above ebay prices.

How so?

Or have a competent purchasing department.

Competence in a purchasing department is more about picking the right distr ibutor to get the right price. They aren't expected to be expert on the pro perties of what they are buying, beyond knowing when to ask engineering if an alternative offered is close enough to do the job.

The best solution is not to block all export, as they're strongly promoting , thus putting people into serious poverty, but rather to set up the means to recycle the stuff safely in Asia. It's not difficult to see how to recyl e thermoplastics, CRT glass, pvc flex etc. That can be done abroad much che aper than in the west with huge benefit to the people that need it.

And don't kid yourself that the business will stop if the US stops exportin g. Asia has no lack of its own electronics to recycle.

All true, I just wanted to bitch and moan. (It takes time to figure out it's a bad part, and not something else wrong.) Usually they come to me. Hopefully this kilo-buck mistake is a lesson learned.

Expert, no. Functional, yes. The CM I am currently working with has been advising me on how to deal with the current passive shortage. They have a program that matches properties and recommends alternate components. That list is sent to me for approval and an AVL is generated from my BOM.

Funny though. When I first created the BOM 10 years ago I had alternatives for some parts. The CMs I contacted were confused by it so I reduced each line item to one component. Oh well...

just out of curiosity can one buy salvaged resistors? I assume it not worth their while, but I've watched them remove them.

China is quite literally a cesspool:

Hey, good news. After some back and forth Manychips is taking the counterfeit IC's back. (With only an hour or two of my time wasted.)

So these chips only looked like the right chip and were full of the IC equi valent of sawdust?

Do you have any good experiences with them? I mean have you bought from th em before?

Even if they take back the chips, I'd still not want to buy from them. The EOL device I use is listed all over Aliexpress, but I haven't bought any. For one, they are more money than the prices I can get in the US. Then of course there is the issue of counterfeit chips.

Never before and never again. It was a purchasing screw-up. They had a 60 day return policy, which we exceeded... 'cause we were using up old stock. But purchasing contacted them anyways, I jumped through some hoops, and we get our ~$1k back.

We've purchased some stuff from Ali-baba after buying less than ideal parts from amazon... crooks lurk everywhere.

Are you saying these parts were bought and put in inventory without testing or an immediate need to use them?

Or are you saying you expected to test them with then-current builds but a mistake was made and the old inventory was used before any of this order so it took more than 60 days to get around to using these parts?

Either way, I'm surprised you would order parts from a company like this un less the need was dire and immediate.
