Interesting report on counterfeit component trends, prepared by ERAI.  PLICs and microprocessors are the most commonly reported counterfeited parts.

One big takeaway: “Suspect/counterfeit parts that have not been previously reported are constantly entering the electronic supply chain and the threat of encountering one of these parts remains very high.”

All that said, the number of fake parts reported is minuscule — just 774 were reported to ERAI. As epidemiologists know, the best way to reduce risk and occurrence of negative outcomes is through research and communication.
