Nichicon is getting out of the axial electrolytic capacitor

business.  Digikey sent me an email stating that all of

the parts I've previously purchased are now End-of-Life

and will be unavailable for purchase after October 31.

 

The remaining manufacturers for similar parts include:

  • Illinois Capacitor
  • Cornell Dubilier Electronics
  • EPCOS
  • Vishay BC Components
  • Vishay Sprague

 

Do you have any opinions on selecting a new supplier?

 

The parts would be for general-purpose use, not for any

extreme temperature environment such as automotive.

I go through a lot of these since I repair/refurbish decades-

old equipment such as guitar amps/preamps, and arcade

machines.

I received the same email.

 

I have been using Illinois Capacitor for a while now.  It's really about price as Electrolytics are a pretty broad breed.  What I mean by that is the tolerance is pretty wide compared to resistors so going by the value is not any kind of indicator.

 

What you might want to do if performance is that important is to but 5 pieces each of various values, similar ESR etc from the vendors listed above, get a capacitance meter and measure all the parts and create a table of the values.  See which ones have the best accuracy based on tolerance.

 

Other than that, I do not see much to compare to other than price.

I've used a bunch of Panasonic electrolytics, and low ESR types...not sure if you are even using low ESR.

 

Electrolytics seem to be somewhat mature & commodity-like, similar to buying a 4-40 screw from 500 different sources.

 

If you need a very stringent spec of some sort, then it's time to get out the magnifying glass

 

Even then, they may come from the same building in Xjangyounimp

 

Toothpicks, tennis rackets, birthday candles, air fresheners. It all comes from China, but much of it—on the order of 60 percent of the worlds cheap consumable goods—comes from just one city: Yiwu.

Datang produces an astounding nine billion pairs of socks each year -- more than one set for every person on the planet. People here fondly call it Socks City, and its annual socks festival attracts 100,000 buyers from around the world.

I kind-of expected to hear that any of them would be fine.

 

Clicking on Nichicon was just one of the ways to make the

parameter list more manageable.  Sort of like "nobody ever

got fired for buying IBM" thinking.  ESR is less important

than choosing a similar size part which fits in the existing

space, with the right capacitance and voltage specs.

 

Thanks for the replies!

Did digikey not give you an alternative?

Vishay BC componetns is the old Philips capacitors division.

Not sure if Kemet, Yageo, TDK, AVX do axial capacitors. Panasonic also still have them.

you could try to put the partnumber you are looking for in the Farnell search enige and se if it comes up with an alternative. Or perhaps Mouser.

Except for the guy at Apple.

The largest known prime number: 282589933-1

In my humble opinion, I'm always right.

They did, but it was just one part from Illinois Capacitor

for each.

Looking on Mouser and choosing 1000uF, it looks like

TDK is the same as EPCOS, and KEMET is an option not

found on Digikey.  Neither of these is a source for

Panasonic axial capacitors it seems....

funny...Digikey has almost 6000 through hole Panasonic caps & ONE axial cap....

 

At least they have 5000 axial from other vendors

 

edit :  swapped AXIAL & Radial

For many Industrial applications Radials are not allowed.  Axials are held in place at the opposite ends as opposed to radials which are held down on one side.  When you go for certain approvals the radials fail the shake table.

Always had good luck with Panasonics, although I almost always use big (33,000uF +) radial ones. 

 

Haven't had to shake them too hard.  S.

Our tech was testing in the QA lab and mounted one of our boards on the shaker.  We stopped by after lunch to take a look & wondered why he was testing a blank board.  He told us we were wrong, he was testing a production board.  After looking some more, we noticed all of the components on the floor.  He had accidentally set it way too high. 

 

Another tech was to do a weekend temperature test at maybe 250F.  Upon return Monday, all of the units housing were molten lumps...there is a difference between Deg C & Deg F!

Well, the farnell search engine has not improved since they were bought by Avnet, but I did a quick search on "panasonic capacitors"  and it found a lot of them:

Not sure of coarse if the ones you are looking for are there, but might be interesting to do a manual search and see if nothing really pops up.

 

The tech stories brought back good memories, we had that a couple of times too, specially the plastics being in not to good a shape after a weekend temperature cycling test.

We had a test engineer that could bring those stories in a funny way, most of the times you could see something went wrong by his face, we already started laughing when he came in with a special look as it meant he had done something stupid.

maybe you can try United Chemi-Con.
