I am looking for a replacement U100 IC for my TDS3032. It is a 100 pin TQFP.
I guess the internal TEK part number is ADG361, whereas the manufacturer's (National) is MM9576-VIG. More information about this chip would be welcome, and information on how to get one would be even more so. Thanks in advance,

https://www.eevblog.com/forum/blog/eevblog-564-tektronix-tds3054-oscilloscope-teardown-repair/50/ There is a supplier listed on eBay. No idea if it is a real part or not, haven't had much luck there. Fakes are very common and customer pays for return and it will likely cost you more to return it than you pay. Regards, Mark

Customer does *not* pay for return if the item is "not as described", and a fake is most definitely "not as described".

Why would they bother reimbursing? Ebay hasn't shown any real interest in attacking counterfeitery. -----Original Message-----

Sorry, no. If it is not as described, ebay takes the funds

from the seller, refunds, and generally you keep the item. If the seller wants it back, they have to pay to get it back. -Chuck Harris toby@telegraphics.com.au wrote:

I just had a return with some cables I got that were wrong. Ebay sent me a shipping label to send the cables back. Once received, I got the refund within a couple of hours.

" Fakes are very common and customer pays for
return and it will likely cost you more to return it than you pay. " I had gotten a fake BATTERY RAM (SDRAM??) out of China, about $40. When I contacted the seller to complain that the chip did not work. After three days without a response, EBAY, automatically refunded my money, via PayPal. I tossed the fake chip and didn't have to return it. Dave On Mon, Jan 7, 2019 at 3:32 PM Mark Goldberg <marklgoldberg@gmail.com> wrote: Some discussion of this device here:

refund within a couple of hours." I had the same experience with a label printer I bought from a fellow in California. He was quite nasty in his responses. I explained to the seller, and ebay, that I have a lot of experience with those brother label printers and was quite specific with what did not work. The seller agrees that it did not work and only offered me 50% refund. I did not accept that. EBAY send me a return shipping label. I very carefully repackaged the printer, taking lots of pictures of my packing and double boxing (that seller would have claimed I poorly packed it). When ebay saw that the package was delivered, they refunded my $200 (or whatever the price was) that same day to PayPal. I've had very positive experience with their buyer protection. I do get a little impatient having to wait three days after the sellers last offer. In the case of the fake SDRAM from China, the seller did not respond at all and ebay refunded me in three days.
