Looking for Component Alternatives

[gogolox]

Hey Everyone. I'm trying to find alternatives to some of these components that have really long lead times. Not sure what will work best since I'm still learning my way through everything. This gonna be for a U87 build. I've done a build before from micparts, and wanted to do another one. Only reason I picked that one was because I was given the PCB and the Cinemag transformer with it. I got the original BOM from vintagemicrophoenpcbkit. If you know of a BOM that's more up-to-date with in-stock components or ones with shorter lead times, please let me know. This is a little overwhelming going through all these sites and cross-checking. I put the mouser links for these below.

https://www.mouser.com/ProductDetail/538-22-28-4030https://www.mouser.com/ProductDetail/505-MKP20.01-100-5https://www.mouser.com/ProductDetail/?qs=EVG5pHsmE1wcsUbS6ZU0wg==https://www.mouser.com/ProductDetail/80-T351A105K35AT-TRhttps://www.mouser.com/ProductDetail/71-RN55D-F-330Khttps://www.mouser.com/ProductDetail/271-560-RChttps://www.mouser.com/ProductDetail/?qs=AFQjeApRbpNSD9T2bqer4g==
I think MOX-200003005JE would replace RNX02560M0FKLB and MF1/4DC5600F replaces 271-560-RC. If I'm wrong, please tell me. I'm just trying to make it work. The plan would be to make this into a gift using the mic body from Studio 939 when they have everything in stock and matching the components with the micparts capsule. Thanks for reading this!

I got item #1 when I ordered the stock BOM, and am not even sure what people would be using them for in this build. I didn't use them.

Item #2 https://www.mouser.com/ProductDetail/KEMET/R82EC2100Z350J?qs=Jv4FAWB%2B0HZYjtR%2BCNGm8A==

Item #3 https://www.mouser.com/ProductDetail/Vishay-BC-Components/MAL202138109E3?qs=HvmVVMoaaMytulioPidhOQ==

Item #4 https://www.mouser.com/ProductDetail/KEMET/T356A105K035AT?qs=wIdqOjKpwXfTK3scNMw7Mg==

Item #5 https://www.mouser.com/ProductDetail/Vishay-Dale/RN55C3303FB14?qs=fq2Dl5oNg0OJS/vVx36KYw==

Item #6 https://www.mouser.com/ProductDetail/YAGEO/MFR-25FTE52-560R?qs=UFD7vfw3J8qdBt3LwToU2w==

Item #7 https://www.mouser.com/ProductDetail/660-GS1-4LC686J

Item #7 is actually in Dany's BOM but they don't explain that those are there for when you can't find the 60 megohm. They will work fine. I don't know if your 30 megohm resistor would work, but the one I suggested will. And your 560 ohm resistor sub will work too. The resistor I picked is a 50PPM part like the original, yours is 100PPM, but it would work fine. Either will work fine.

This might have been better posted in the Neumann Vintage U87 Clone : Build Thread we already have here. And lots of these subs were already listed in that thread. Unfortunately it's really long, but it's worth skimming/reading if you're going to undertake one of these builds.

Getting good at Mouser's "Show Similar" tool is also something to practice if you're going to get into DIY. Particularly now with parts going out of stock quicker and replenishment times getting longer.

When you can't find a WIMA film cap Mouser almost always has a Kemet film that will sub right in.

Octopart is very useful for things like this, it will search all the distributors and show you what's in stock where.
