Radioberry - Future with component shortages

[Ravi Miranda]

Hi,

Hope everyone is well.

I was looking to order some components at Mouser. There seems to be a
shortage of some key items

1. ASTXR-12-38.400MHz-514054-T ----- > Factory not accepting orders.
I can get the footprint in Beta 5 changed to accept a larger TCXO with
a similar spec.

2. MABA-010143-FLUX18 - Not available in small quantities
Will this work instead?
https://www.mouser.co.uk/datasheet/2/1030/TC8-1_2b-1701131.pdf
Or would it be best to get all the stuff from one supplier?
Could both transformers be made from BN43-2402 or BN61-2402?

3. AD9866 - headed towards obsolescence - Is there another product
that can be used?

4. 652-CDSOD323-T05LC - No stock - Any other replacement?

5. MPZ1608S601ATA00 - no stock - this might not be critical - can be substituted


What are the group's thoughts on this please?

Best 73,

Ravi/M0RVI

Hi Ravi,

I ordered some electronic parts from Digi-Key for my second Radioberry (CL025 version) and PreAMP board  last month 

1. ASTXR-12-38.400MHZ-514054-T and

  4. CDSOD323-T05LC was in stock at Digi-Key. but,

5.MPZ1608S601ATA00 I didn't buy(I had it).

2. MABA-010143-FLUX18  I'm going to use the BN43-2402.

  The discussions of the Hermes-Lite group are also helpful. and also Hermes-Lite2 schematics.

I'm not sure about #3.

73!

Hi,

Raising the issue of non-availability of parts.
Are there any alternatives for ASTXR-12-38.400MHZ-514054-T. What
parameters are important here? foot print and pin out? Anything else.

Apologies for the repost.

Ravi
