content: 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 ICsHigh speed ADC3PA1030 (50MSPS 10bit)3PEAK -https://list.szlcsc.com/brand/926.htmlHigh speed DACGM7123C (330MSPS 10bit) - drop in substitute for ADV7123High speed op-ampSGM8061MS8051TPH2501GS8051, GS8091RS8751SG micro -https://list.szlcsc.com/brand/280.htmlGainsil -https://list.szlcsc.com/brand/11403.htmlLow noise LDOSGM2028Power management/miscTP199 (current sense amplifier) - INA199 substituteFP6373A (buck IC) - 5V 3A SOT23JW5033S (buck IC) - 18V 2A SOT23RFICsRF switchMXD8625C - spdt, 35dBmMXD8641, MXD8661 - sp4t, sp6tCanaanTek -https://list.szlcsc.com/brand/11832.htmlMaxscend -https://list.szlcsc.com/brand/11684.htmlLansus (huawei) -https://list.szlcsc.com/brand/11734.htmlMMIC amplifierTBDRF mixerTBDRF synthesizerTBDOtherMicrocontrollersGD32 (risc-v), ESP32, Kendryte K210, ...FPGAGowin, Anlogic, ...

content: 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

content: 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.

content: OwO, thank you for this thread. It is very handy.I am trying to search for similar ones and have some small update:LDOAs Dave mentioned SC662K 1 cent LDO, but seems discontinued on LCSC.They have also SC1117-3.3 for 700mA, but a bit more expensive.MCUCH55x, 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 sensorsand much more sub $0.10 herehttps://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/)

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

content: 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 areFor general partshttps://www.njr.com/semicon/lineup.htmland Renesas for processors and high end stuff
