What is your longest lead-time wait?
« on: April 28, 2018, 11:41:47 pm »
Recently a new placed order and lead-time 21 weeks to wait :popcorn:
Well, this is my record. Hope that they can delivery early since a chip is appeared in other suppliers... we will see.


What about you?

I've seen 52 weeks recently.  Supposedly some parts from Micron are currently listed as even longer.

Over a decade ago, I had a Burr-Brown part that I'd used for some time, but there was no stock.  The distributor showed a 2.5 YEAR lead time, but they could tell me the exact day the part would be manufactured.  I got frantic, and found that TI made an equivalent part for 1/4th the cost, and reviewing the datasheet, it sure seemed compatible.  I wasn't totally convinced until I actually put them in the circuit, and it worked fine.

100nf capacitors are around 40 weeks
our assemblers keep asking to plan orders ahead for one to two years

LOL did you specifically search for the 100nf with the longest possible lead time? It is the most common cap after all...

25 weeks has been the longest I had to wait for a part, otherwise often the assembly houses I work with come to me saying that a particular part has long lead time, but for most parts I try to have several alternatives to compensate for this.

Are you after some fancy caps that made once per year and you just missed a time slot?

Digi-key shows over 2 million components in stock of just ONE part # in 0805 size (their part # 490-4789-2)

I guess you guys have been living under a rock or something XD

there is currently a huge shortage of capacitor, the worst is 100nF it seems, it is apparently due to a consumer market grow in demand  (my guess is that to keep the production lines open they are buying anything that even resembles a capacitor unregarding of cost or higher than needed specs) unmet by producers that are at full capacity and unwilling to expand capacity for fear of another economic crisis...

and ok the distributors have something in stock but, first not all MLCC have been created equal, second in certains market substituting a component for another could be extremely difficult, in aerospace for example it probably requires mountains of paper to be reviewed by FAA or equivalent, medical is probably similar, etc

A few weeks back I had a pretty basic 1uF 16V capacitor in my list, and I specifically cheeked that all positions had at least 100K in stock, since I was aware of the shortages (and DK warns you as well).

I ordered 500, and only got 200. So I don't know how accurate their stock numbers are on those parts. It is possible that someone else bought the rest of them, but I kind of doubt it.

I had Avnet change an item from "in stock" to 4 months after they confirmed the order and shipping date.

Plonk.
There are lies, damned lies, statistics - and ADC/DAC specs.
Gliding aphorism: "there is no substitute for span". Retort: "There is a substitute: skill+imagination. But you can buy span".
