Substitutes for american parts thread
« on: November 16, 2019, 05:23:51 am »
This is a thread to gather up possible alternative parts & solutions for american RF & analog ICs due to the need to diversify the supply chain in face of politicization of electronic parts.
I will update keep this post updated as new solutions are added.

Note: avoid discussing politics. I have nothing against Americans but like any other business we have to be risk-averse, and recent events have shown that single sourced parts are a substantiated (and not just theoretical) risk. The criteria for a part to be included on this list are simply that it needs to be manufactured by a corporation with majority (50%) of operations not in the US, since that was the main criteria that was used last time with the embargo against Huawei, OR if there are reasons to believe that a specific corporation can not be used as part of a trade embargo.

Analog ICs
RFICs
Other
  • Microcontrollers
    • GD32 (risc-v), ESP32, Kendryte K210, ...
  • FPGA
    • Gowin, Anlogic, ...

At the end of this war, the Chinese will have a full line of cheap mass production components and USA will have a very expensive line on low quantity state of art chips who only US government and military will be able to buy, Everbody else will buy the Chinese ones even with a 100% tariff

Added DACs and power management chips.

I am still looking for RF synthesizers and mixers. It is the last piece of the puzzle that will allow a fully second-sourced NanoVNA V2 and other RF test equipment. I can actually use diode ring mixers and get similar performance, but a simple Gilbert cell IC can't be very hard.

Taking advantage of this topic, you could make a topic indicating which manufacturers are reliable (following the datasheet specifications), because I often look at https://lcsc.com/ and see products of unknown brands to us westerners (even playing on google has no comments), then it is difficult to use.
