Fake Nichicon?

Don't know about the first one. I don't have any snap in Nichicon to compare. But the sleeve printing looks messy on the second one. In my experience Japanese capacitors, ICs and transistors all have very neat/clean printing/labeling/presentation.


The general consensus is do not get caps on Ebay or AliExpress. (Because of fakes.) Where did you get those two... ?
 
I can't see the seal on the legged cap and I agree with @kozard - the printing isn't up to the standard of the first one.

My experience here in China is that Nichicon is the most widely faked brand. To lower the risk of fakes, go for the less well known Korean manufactured (but Japanese origin) brands like Samyoung. Just my 2c.
 
From nichiconcapacitors.com

Whois "nichiconcapacitors.com" is a godaddy registration the registrant has a BG (Bulgaria) country however the further details are withheld..

Looking on their site this matches: Bulgaria Sofia 1000 for their contact point however the hosting is actually in the US (173.254.28.32).
Registrant Organization:
Registrant State/Province: Sofia
Registrant Country: BG

So why would nichicon (nichicon.co.jp and nichicon.com) offer their caps through a random Bulgarian hosted site registered on 2018-09-05?

Surely they wouldn't licence out their brand name?

The real Nichicon: nichicon.com whois lookup - who.is
Note the use of privacy legal company, also look at the date of creation so you'd expect an site registration older than 2018...

Lastly there's use of a proper service on the real nichicon address to manage their internet presence - rather than godaddy with a hosted site (not that godaddy is not professsional - but rather the disjunct in approach).

There's more ways to find out the ownership.. but that more than it's worth.

they look and most likely are original. Tme.com is a legit business.
nichiconcapacitors.com ... well with this name would be real stupid to sell fakes , they work only with paypal, So Yeah! I would think they are legit.

Tme I don't have an issue with, but just reselling one brand of caps - in a cut throat market? It would raise the level of risk in my eyes. It may be a legit startup and kudos for making it work but for me the numbers don't add up.

Real Samyoung and also Rubycon can be purchased from Electronic Components Distributor | JLCPCB & EasyEDA Parts Online store - LCSC.COM for good prices.
 
Looks and even worse through a fuzzy processed (.jpg) Internet picture seen onscreen means NOTHING.

Unless it´s gross as in brush painted letters or using crayons.

I silkscreen my front panels and PCBs and can get as much fine detail as anybody.

FWIW local (Argentine) printers successfully silkscreened US Dollar bills, go figure, so making accurate cap sheaths takes skill and patience but CAN be done.

Much better tool: *measure* them.

Either meet original specs or don´t.

And IF they meet or surpass original (high quality) specs, I´d happily use them any day of the week.

So: how do they MEASURE?

I don't recommend that. There is much more than initial measured specifications that matter. I want to know it is from a genuine source so that the longevity at temperature is what it should be.

I have spent far too much time repairing equipment with poor quality capacitors in it. I suggest making sure that you use quality capacitors from reliable sources.


I do not want to exchange a quality Nichicon for a bottom of the barrel capacitor brand.


And don't forget all the fake online capacitors that did not meet the printed voltage rating...

Cant judge about the snap in but the KW? looks rather genuine to me - I compared the printing and the tarnished dark/grey almost black sleeve with mine of the kz. (I usually buy them from mouser). Gold fits also it has almost some green tint. The smaller caps of nichicon are slightly polished less silky and the gold is more brililant and leaning towards more yellow/red gold. As in your imgur second link visible.

This might also help ...for the through- hole

at least a better fake 😉

btw. afaik Nichicon uses tinned copper (OHFC even?) wire so a fake might have only steel ones.

Bought Nichicon MUSE KZ (UKZ) capacitors from ebay (seller: atop_authentic_action) and I can tell you that, that from this seller they are original! I bought some capacitors for my Sansui Alpha AU-907i MOS Limited and I opened the largest one 470uf/50V and I was surprised. The legs are copper made and the interior looks original. You can look and judging by these pictures. I should get also in few days some capacitors from Mouser Electronics and I will open the same cap 470/50V (but instead of UKZ it will be UKW) and I will post again for the deferences.

When I order Japanese brand electrolytic capacitors from Mouser or Digikey I note that the sleeves and the printing look very pristine. When I get the supposed same brand capacitors already installed on a PCB from AliExpress or Ebay I note that the sleeves don't have the same pristine appearance. It makes me a bit suspicious so I stick with Mouser and Digikey.
