Currently building a Nava V1.02 (on the snare at the mo) and an extra 1M-Ohm resistor is required for the Snare Decay problem described here:
viewtopic.php?f=24&t=1555&start=40#p10275

I assume it's not included in the Mouser BOM as I only received 21 x 1M-Ohm resistors..

Please could you confirm, and update for future builders ?

The Mouser BOM is missing a few bits most I have found replacements for most but want to check for some advice here before placing orders elsewhere.

1. Is this a suitable replacement ceramic disk in the snare circuit? it's only difference in spec is it's 1KV instead of 2KV https://www.mouser.co.uk/ProductDetail/ ... OkpihZg%3d

2. The STM TL074CDT for the MUX is out of stock. TI have many but with different suffix's - Is there a best suited suffix or a CDT equivalent?

3. The OnSemi MC7815CTG is out of stock is there a suitable replacement? OnSemi have others but with different suffix's.

That's it. The rest are just resistors and caps, nothing else major.

can anyone help me find these last two parts as Mouser has run out of stock and backorders won't be in until 2019 lol

cheers

@serum:

1) Thats fine
2) this one works as it should -> https://pl.mouser.com/ProductDetail/Tex ... dcvfXdc%3d
3) any 7815 will be OK

cheers

@JimAudio

I didnt use this additional resistor and everything with snare is great.

cheers

Hey y'all, I'm new to the forum and just bought the BOM for the 1.02 kit, and currently 2 items are discontinued and 5 are backordered. I talked to mouser and got replacement suggestions and wanted to post in case anyone else is buying these right now. Hopefully these will work fine

Thanks!
GOt my kit and will start now

Hey Community! My Nava kit just arrived and I'm so excited to start the build! I'm waiting for my Mouser order though, and the longer I wait, the more parts start missing. At the moment, I need to replace:

"559-FOXS160-20-LF FOXSLF/160-20 16MHz 20pF Fox Crystals" 1 1 Okt. 28, 2019
"710-885012207084 885012207084 WCAP-CSGP 470pF Wurth Multilayer Ceramic Capacitors MLCC - SMD/SMT" 16 16 Okt. 29, 2019

Do you know if I could just use similar parts? The easiest should be those 649-68602-406HLF generic pin headers. For the rest I'd try to find drop ins with the same specs. Suggestions? Do you agree? I'm pretty much clueless and would appreciate your help very much, especially with that CD4051 IC.

Edit: After hours of searching for replacements I finally discovered another distributor (http://www.rs-online.com/) that has all those items in stock and ships from Europe. Phew! I skipped the 2-rows 6-connectors pin header though. Didn't find it used in the building manual. Btw.: I have an awful lot of these SMD caramic caps (200) and multiplexers (20) now cause of the minimum ordering quantities. Hit me up if you need them.
