Did you mean http://www.futurlec.com/ ? They are there!

Be careful as I (and others) have received counterfeit parts from them. In my case it was nearly 200 L6202's which they to this day have not taken care of. I wish they would have done the correct thing and taken them back and/or given me a refund/credit. But instead they pretended that there wasn't really a problem. It's too bad too, since I do like their prices but just can't bring myself to purchase from someone who sells counterfeit parts as original. (And no, I don't know if they thought they were counterfeit or not - quite frankly, it doesn't matter to me since they basically quit responding to my emails trying to get a resolution to the issue). -forrest cdb wrote: {Quote hidden}> OK, thanks, suffering major brain fade today! :( > -- > cdb, colinspam_OUTbtech-online.co.uk on 10/28/2009 > > Web presence: http://www.btech-online.co.uk > > Hosted by: http://www.1and1.co.uk/?k_id=7988359 > > > > > > > >

Hey, what exactly are "counterfeit" parts and how do you know which ones are counterfeit and which ones are not?

Depends. The simplest cases are binned parts being sold as "new", or stolen parts sold as new. I've heard of some people actually taking parts off of old boards, reballing them (in the case of BGA) and selling them as new (obviously this only makes sense for expensive parts). I've even heard of some cases where parts are relabeled with a more expensive part number, change a few numbers on say an MCU (many MCUs have multiple parts in the same package, so if you take an MCU with 2k RAM and label it as if it were a part with 64k RAM you can sell it for more). For cheaper parts there are some manufacturers that make parts and then label them with a "brand" name, exactly the same stuff as what happens with designer purses. In general it's safest to buy parts from authorized distributors, but even they can be caught with bad parts. As for how YOU can tell, it's exactly the same as designer purses: sometimes it's obvious (name is mispelled), sometimes "experts" can't tell it's a fake. TTYL

Somehow it wasn't quite up to snuff. Another favourite of the shadier vendors is to change the temperature / reliability code, remarking consumer-grade parts to look like extended-temp parts, or even military-grade parts. -Randy

Sometimes they are ones tested as defective and not properly scrapped (aka somebody took them from the garbage can). Sometimes they're a relabeled part (take a low-quality, low cost part and relabel it as an expensive one). And sometimes they are actually a knock-off manufactured in some fab somewhere where the parts are manufactured under less than quality conditions. In this case, I had to send parts to the manufacturer - although the very high failure rate was a good indicator. RAM chips are notorious along with transistors, etc. On the futurlec counterfeiting issue, google futurlec counterfeit , and read the threads .. pretty common stories, lots of ok responses and seemingly always 1-2 people saying that they got counterfeit goods. -forrest

Wouldn't have much confidence the Rubycon cap isn't a fake. Also if you see Bubycon parts it isn't a typo, someone in China decided it would be a good name for a capacitor manufacturer... The only fake problem I have personally experienced was with a Fairchild logic level MOSFET on some boards assembled in China. They looked fake and were not logic level enough. The threshold voltage was way out of spec.

They are marked as On Semiconductor parts, but the metal tab is too thin, about the same thickness as the package pins. I can bend it with my hands. In every TO-220 package I have ever seen before, the metal tab is much thicker than the pins.

According to their specs, that tab is between 0.508mm and 1.39mm and the pins are between 0.46mm and 0.64mm. So in theory you could get a case that's within spec and still has thicker pins than the tab. Gerhard
