DIGIKEY sold me 8 Years Old electrolytic caps?!?
<< < (8/9) > >>
ColdPower:
We got caught into that obsolete status, but: obsolete means exactly that the part isn't anymore manufactured or is planned to be stopped from manufacturing, for which the manufacturer would give as seen clear obsolescence notice of about an year. In this time the part may be marked as obsolete or last order, but that doesn't necessarily mean one should assume the stock to receive would be beyond recommended usage time frame and long past expiration date. As also pointed earlier, some series can have up to 42 months till expiration, which can be well past obsolescence date and again, doesn't mean parts are not recommended as viable for usage. Also as seen, expired caps are not recommended for use by the manufacturer, so whatever that part status, one would expect it to be usable according to manufacturer advise? This just as it happens is rather important with electrolytic caps, otherwise, not that important really, unless solderabitly is a concern as also pointed, but if you ever had to deal with 40+ years old soviet resistors, it wouldn't bother you that much  ;D

Hope that finally clears the obsolete part status.

And in answer of the question, I did order exactly P13146-ND and have earlier this year as well, part was available, but again, I didn't pay much attention to the obsolete status, as cleared above, it can be obsolete and well within recommended usage frame. I believe in this case that should have been automatically caught by the stock keeping, same as in a supermarket if the milk goes past exp. date, it's not sold anymore, although may still be drinkable...

Sorry, that got long, but lastly, as mentioned before, I have received active caps which I just now realise are in fact past expiration date as well, so seems like clearly this is just not at all tracked in the DK's stock keeping. I guess it is what it is and being small clients buying in hundreds not tens of thousands, we'd just have to accept it  :-\ I was just really surprised it actually happens and not an isolated case and even more, that a lot of people seem to actually find it normal and acceptable.

You have seen obsolete status, did not bother to check, bought it anyway. Then complain that you got component almost as fresh as it was technically possible.

It's not like past this date capacitor is bad. It's about recommended reconditioning. If capacitor will be used close to max voltage in a circuit without current limit, it would be the best to recondition them beforehand.

What you quote was for ACTIVE part, read again the post above as well re expectations!

The way I see it, there is not much to be gained from discussing or arguing this. You got parts you're unhappy with. There are only 3 possible - and simple - solutions:

1) Accept that you won't be able to find new stock of this part and use them anyway.

2) Return them (or don't) and find new parts with equivalent specs.

3) Call Digikey. They have excellent customer service. You'll get a real person on the phone to whom you can explain the situation. If you are unhappy with the caps or feel you were misled I have zero doubt Digikey will refund them for you. Digikey made ONE mistake, ever, in my 10 years of dealing with them: they sent a part in the wrong SMT package. I called them and they swiftly apologized and immediately overnighted new parts for priority AM delivery at no cost to me. They will take care of you.

Caps sitting in cold storage with no electrical or thermal stress whatsoever are going to last decades. Even electrolytics, particularly high-quality electrolytics. A big part of the reason they "expire" in 48 months is so that manufacturers don't need to deal with angry OEMs for whom a 0.05% failure rate over 10 million parts is a big deal.

Not really looking for anything to gain or argue, as mentioned, was wondering how common this is and is it normal to happen. Although in my case this seem to be rather common to happen and replies show it's far from ideal for electrolytics, apparently most would see it as normal and would be okay with, so as stated earlier, we'd just have to accept it as normal, even if against manufacturer advice....

Also it wasn't the point of whether DK CS would refund or not, but again, rather  is it acceptable practice and what expectations for orders should be, but I believe we've answered that one too.
