more fake eBay semis (OPA627=AD744)

[Jsixis]

There are honest sellers from china on ebay and I got lots of genuine ICs, transistors, and capacitors, but many times you have to know how the real part looks like and carefully see the ad pictures. If pics are blurred even lightly, or small, stay away. Seller's feedback reputation also speaks for itself.
There's also an axiom that says that you get what you pay for.

Cool. very interesting. maybe someday i will try to open one. What kind of microscope do you use? I guess it very expensive. your website make me shocked ! what kind of job you are working now? I never see like this before. Interesting. Thanks for sharing

Yes the scopes are Leitz, but they are equiped with high rez video as well as confocal lasers for chip surgery. The total cost is >$100K

Neat.
This is what you can do with 2k worth of Sigma glass and a Flashlight... 😛

Notice BB logo and part number, and BIG JFET's

Thanks for clarification, and nice to see designer of the IC I decapped 🙂
Reader sent me another OPA627 and it matched your image.

Just buy at Elektronik und Technik bei reichelt elektronik günstig bestellen. Bought 2 pieces genuine OPA627 incl. shipping (to the Netherlands) for just €41,50.

Sure they're genuine? Checking is easy, you just have to remove the cap and...

You tell me🙂. You're living in Germany. Is reichelt a trustworthy company to deal with? Even at mouser.com you can order the OPA627. Anyhow the OPA627 I got really sounds much better than the other opamps I tried.

I order almost exclusively from Reichelt, but I can't tell you for sure. Their ONS stock is genuine, never experienced any problems so far and actually decapped some MJ1500x's. Panasonic FC's are genuine, too (whereas I have received fakes from ASWO lately). Their no-name parts are cheap stuff like from CDIL and INS, but the brand-name parts are likely to be genuine, especially the LT stuff which seems to make up half of their assortment 🙂.

I can't imagine that Reichelt would sell fake ones. The website looks professional and the shipping cost is cheap! Just €6,95. Almost the same when I order at a Dutch web shop (€6,50). I think I'm going to order often at Reichelt! They deliver really fast. Within 3 days I got my order.
