Hi Riaan,
Please check if Mantech or Communica has these components - don't buy any just yet, just get the data on what is available.
(Get guidance from Danny or Eric on this if its new to you)
1. CRYSTAL 12MHZ 8PF SMD / Manufacturer No. 'ECS-120-8-36-CKM-TR
2. 22pF Package: 0603
Don't worry about #2, it the first one that I need to know if it is locally available.
3. CH340C package: SOIC-16
Regards
Neal
