Hi All

 

I hope all are well.

 

How is everyone coping with component avaibilty.

 

Has anyone used Octopart to source components and used the following suppliers?

 

https://www.win-source.net/atmel-atsamd21j18a-au.html

 

https://www.heisener.com/ProductDetail/ATSAMD21J18A-AU

 

 

 

 

 

Thanks

Regards

DJ

1) Some suppliers say that they have product when they don't.

 

2) If they do actually have the product then when you enquire they will quote a completely different, ie much higher, price. 

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

But are the components reliable and genuine?

 

Have you had any positive experiences?

 

 

Thanks

I recently had a bad experience with Win Source. They advertised having a particular Atmel part in stock, at a high price, but at least they had it. So I placed an order for $3000 worth of parts. The order was paid, confirmed, done.

 

Three days later they emailed me to say they were revising the price, and instead of $5.18/each they wanted $20.97/each. A retroactive 4x markup for an order that was ALREADY PAID. Then to rub salt in the wound, they dragged their feet for four more days before they refunded my credit card.

I guess it best to avoid them.

 

Best to wait till January to see if any lead times change via the official distributors.

Same here. I placed an order, based on Octopart and their own website, for a quantity of chips that were shown as in stock at $1.629 each. A few days later I got an email to say that they weren't in stock but they could supply them at nearer $17 each! That's a ten-times increase. Needless to say, no matter how badly I wanted them, I cancelled the order.

Has to be QFP?

Reason : QFN restocks 15-Mar'22 and 26-Apr'22

Lead Time | World's Largest Inventory of Microchip Products

 

edit : those dates might be related to a second assembly site

Buy the parts and have them delivered, or at least use a reliable supplier and get a scheduled order in, before you do the redesign.

We have redesigned our boards to take more then one layout, so they will work with what ever parts we can get at the time...

It helped to plan ahead! wink

If you can pay $170 each, they can even rob for your!  Here "rob" means robbing IC from other companies through violence.

Let's not go overboard. It's tough to do business in the electronics industry if you shun anyone with a Chinese phone number.

Thats a good idea.  I will try and see if i can add both QFTP and QFN package on the same PCB.

Thanks

So where do people source genuine components if they are making there electronics in China?
