Crapola.......

Group buy MN3005's:

Image


first clue - all have the same date code:

Image


second clue - fake on top - genuine on the bottom - note the size of the logo:

Image
Image
Image
Image
Image

genuine MN3005:

Image

third - geniune 3005 legs:

Image

fake 3005 legs:
Image
Image

fourth - overall shape and top indentation (genuine on the left - fakes on the right):
Image

that's a "real" one on the end to compare the fakes to:
Image

the lineup (real 3005 on top) - take note of the second one from the right - note the "imperfection" in the top of the chip:
Image

once again - overall shape and lack of a top indentation:

Image
Image

I have plenty to test against - if there's any doubt at all - these ARE fakes:
Image
Image

I stopped after testing 3 - just for kicks - I knew they were bunk when I emptied them out of the tube - but I figured "what the heck":

I do have some legit 3005's that look pretty similar to these fakes - they don't have the "border" around the top. But the "crisp" edges of the fake IC were a little too clean and crisp, in comparison to my real 3005 - the body of the IC is "too" squared up..... side by side, though, it's night and day.

fake on the left, genuine on the right (my genuine does look different than dz's)

WOW! This is very disappointing news. Thanks for taking the time Dan. Do we have a plan B?

I have four red boards from the last batch populated, and no chips...arrrggggg!

Daniel,

Did you test some of em as well in circuit?
(and more tricky, do you have capability and guts to test them in a MN3205 type circuit)(This type of packaging (with the missing pins) is difficult to fake)

Some of your evidence doesn't necessarily mean fakes. A different imprint in the bottom, as well as shape of pins could suggest another wafer packaging machine. These chips have been manufactured for years. Now if they had the same datecode but different imprints that would be a better sign.
Sorry. Plain out of planes.

Fake on the left. Real on the right. Note date codes.
Look familiar?
Different source. Same crap.
BTW, the bad ones I got from Utsource (who admitted they were fakes) were promptly replaced w/real MN3005's that all tested working.
Group buy for V3205 anybody?
Have you lost your mind? People are only interested in building fuzz boxes!

I've got another quote from the same source we bought the MN3005 from last time. $18 each and he says they're from the same supplier the last group buy came from. Same deal with 30 day return policy. I remember that out of 200 chips last time I had maybe 5 bad ones.

Should we go for it?

That is really SAD news! Hope this does not turn out ugly for Ron!


I've got an offer from a German supplier, who guarantees real parts:

100 MN3005 NEW QUOTE 100 Pcs. : 17,99 € / Pc.

500 MN3005 NEW QUOTE 500 Pcs. : 11,06 € / Pc.

Dirk (and all),

Yep - I did test them in my Aqua Puss. No delay at all. Trimmers were also tweaked - and no delay.

Unfortunately I do not have a 3205 circuit around.

Damn, how incredibly frustrating. I want to say thanks to you guys for putting in all this time and effort, even though the results are not what anyone wanted (so far).

Frustrating huh? I sat like that with 10 3007's, hoping at least one of em would work....

Thanks for the detailed info mate. Much appreciated. I hope you'll be able to minimize losses on these.

Looks like I'll be able to return the MN3005s. I can order the other ones and have them in a couple of weeks. Should I go for it or is everyone too bummed at the moment?
