Please post here if you find a Mouser part is out of stock or has a long lead time. Please provide:
Note that end-of-life parts might remain in the tool until the supply dwindles.
in UI-Essentual-Kit - the last element of the boom is used the maker number: (makes not a different, but it confuzed me… came to a part which not exist, but as i can see evertything is in stock! sorry.)
4816P-T02-103LF|1 (thats maker nr.)
652-4816P-T2LF-10K|1 (thats mouser nr.)
782-6N138 CORE-essentual-Kit 1800 in stock - but stopped production - can i take 6n136 instead? or others (will not that go away that fast,but since on lcsc they have for example 136 but not 138…for example)
Thanks, I fixed the resistor network!
For the optocoupler, the 136 is 10x faster, maybe it needs other components altered? I will leave the 782-6N138 in for the moment, but there are a couple of substitutes available (859-6N138, 630-6N138-000E).
to 6N136, by searching the midibox forum there are some posts that they used th 6n136 with no problems… i will try them…
to not blow up the SEQV4+ tread:
? see i right that you add this lines @ the end of boom:

all other is unchanged? > means you just add this lines to the end of the Boom List?
652-3306F-1-103 (for displays?) can i substitue the 10K trimmers @ corekit with 20K ones? >

Andy will confirm but yes, it’s a voltage divider.
cool thanks

Andy, I will try the 6N137(CMOS output) too very soon…

The only things I’ve added are basically ribbon cable and IDC headers. You don’t need the USB-AB cable/SD card I’m sure. One of the pin headers was changed a week or so ago (now 929700-01-36-RK), if you bought the longer ones they’ll still work but you’ll probably have to trim them shorter.
Also, there was a period where the multiple projects in a kit were not counted in the kit BOM, thus you might be missing Hirose headers (MDF7-10S-254DSA55).

Should work out fine. Actually, the OLEDs don’t use a backlight, so you can even leave them off.

Actually out of stock for another week or so
(deletet content) forget it — my fail (this excel list and numbers … getting confuzed)
No worries, imagine the pain at getting these lists together!
may it helps anyone - i have made a boom for aviable LCSC.com parts > there are quite much that have to order from mouser anyhow (i have qoted them - but i am not very confident they will be cheap)
(untested)

thank you for already completing the one for dipCoreF4 also

It seems Mouser only has 33 of the MEC switches left (you need 34) and they have a 30 week lead time on getting more!
I found RS Components still has them.
What about the DMOS chip? TBD62381AFWG,EL. This is also out of stock at Mouser. Can I substitute another IC in the same series?
MEC switches are available at Reichelt:

TBD62381A is available at Digikey:
https://www.digikey.com/products/en?keywords=TBD62381AFWGELCT-ND%09
an alternative part is TBD62083AFWG, with good amounts of stock listed at Mouser (the flyback diodes shouldn’t affect the operation):

Andy if you could suggest the replacements for those it would be great, the capacitor should be easy enough to find a replacement but your eagle eyes might spot something I do not! 
The LED is available at Digikey: https://www.digikey.com/products/en?keywords=WP154A4SUREQBFZGW
For the capacitor I think any 50v .1uF X7R 1206 10% should be fine, but I’ll let the powers that be give a definitive answer. 
Hello, I updated the BOM tool for the caps (current stock 30k). Never heard of “flex termination” caps, but they sound useful! Probably they’ll also go out of stock at some point.
The LED is due to arrive in about two weeks, so I won’t change that one for now. Essentially any common cathode 5mm RGB LED should work, or even a bicolour or single-colour version (only 2/3 dies are used in the case of an RGB). The Beat LED step is done almost last, so it shouldn’t hold up the build.
Here’s the first link I found on eBay (recommended to get a diffused lens):
https://www.ebay.de/itm/50PCS-5mm-4pin-RGB-Diffused-Tri-Color-Common-Cathode-LED-Red-Green-Blue/201570892720?hash=item2eee8fbbb0:g:8HUAAOSwlHRXIk~D:rk:1:pf:0
Note that the delivery might come after the Mouser one comes back in stock, but it’s certainly cheaper through eBay!

Any recommendations are very welcome!
You’re right about the cap though: the specs are very non-crucial for this part.
FWIW, I would still suggest to order the Beat LED with the main order. You normally won’t have to pay for shipping a second time on backordered parts (at least I’ve received a smaller packet later in the past).
