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.

OwO, thank you for this thread. It is very handy.
I am trying to search for similar ones and have some small update:

LDO
As Dave mentioned SC662K 1 cent LDO, but seems discontinued on LCSC.
They have also SC1117-3.3 for 700mA, but a bit more expensive.

MCU
CH55x, amazing ~$0.30 MCU with USB ( https://www.eevblog.com/forum/microcontrollers/lt30-cent-mcu-with-usb-controllers-capactive-touch-more-wchs-ch55x-series/ )
HT68F001 - Sub $0.10 exceptionally low power MCU with flash, that can replace $0.5 "fixed function" timers for sensors
and much more sub $0.10 here https://cpldcpu.wordpress.com/2019/08/12/the-terrible-3-cent-mcu/
And for sure famous: https://jaycarlson.net/2019/09/06/whats-up-with-these-3-cent-microcontrollers/)

STMicroelectronics is European, so if you are hoping to avoid American items, you can look to them as well. So is Infineon.

And NXP (formerly Philips).

(Infineon is former Siemens.)

I prefer to source from the Japanese sector generally. I always find their stuff comes with no to little surprises and the businesses are stable over time so I generally do not redesign often (i.e. discontinued parts are not generally a problem - although like anything it does happen).

My goto's are

For general parts
https://www.njr.com/semicon/lineup.html

and Renesas for processors and high end stuff

The original poster is from China, and a lot of Chinese businesses are very reluctant to source from Japan.

Well in a situation where you have to compromise you pick your battles. If america is a no no they have to go somewhere, I think Japan is one of the thrivers as IC's go?

Unless you do advanced processes, SMIC and TSMC no longer offer cheap MPW shuttles, as they tend to offer only large volume fabrication services, and it's up to you to find a private cost sharing partner to share silicon area for prototyping.
There are third parties who will coalesce designs onto a shuttle at TSMC. I've no experience of using them, but I know they exist.
