Hello,
has anybody bought ICs from Jotrin Electronics Ltd. of Shenzhen?
They have a Xilinx chip I need for a sane price, but I hear so many horror stories I wanted to see if anyone has experience with them.
Thanks,
Jon

There are many, many scams around components. My advice is - don't do it! Risk to be scammed is very high.

This said, I found Taobao to be OK. Because they aim at local customers only, so scamming is much more difficult.

You're best to work with a broker you either can trust or someone has vouched for. I can recommend June at Keming Electronics. We've tried to avoid grey market as much as possible but where there has been no other choice June has been great at helping us find quality stock at realistic prices. This far everything she has supplied has passed qualification when we received them.

I got counterfeit Maxxim CAN controller ICs from a broker in Germany. Worst part - they worked during our tests - but not in the extended customers tests -20 to +70°C for 24 hours. They refunded the ICs, I still lost 50,000 in damage, only - and that was really lucky!

Well, yeah, the only way you can guarantee it is to purchase from an authorised distributor with traceable provenance. Unfortunately these days this simply isn't always possible when the only authorised option is a 72 week (or worse!) lead time. You do as much qualification as you're comfortable with.

Maxim parts are traditionally pretty notorious for counterfeits though, so I'd consider them particularly high risk.
