While the ending of the COVID-19 pandemic has eased many of the drastic shortages of electronic components, shortages of some parts still persist. One problem that has long plagued design engineers has been the presence of counterfeit electronic components from grey market sources, which originate from China or other sources outside of established component suppliers and distributors.
These counterfeit electronic components may at first glance look like real components, but as this video from YouTube site Fixed Until Broken shows, a closer look is needed to visually detect parts that may be grey market. Grey market components are potentially plagued with issues such as poor traceability, substandard quality, poor storage, and unproven performance. Once such a part is in a system, it could fail and cause issues with other parts as well.
This informative 19-minute video covers some of the investigations of rebadged chips one might find on eBay or Chinese fleamarket IC websites. While these suggestions may not result in catching every fake component, they are a good place to start.
