Counterfeit industrial electronics are becoming an increasingly serious problem. High value and obsolete components are frequent targets, with fake products entering the market disguised as genuine items. What may seem like a cost saving purchase can quickly result in equipment damage, downtime, safety risks, and legal consequences. According to Alexander Lupu , technical advisor at S7 Automation Europe , the issue is growing rapidly. Some counterfeit parts are sold as brand new ones, also refurbished parts are re-labelled and resold as new , and serial numbers are manipulated to imitate newer models. In critical environments such as manufacturing lines Oil and Gas automation systems, these risks are posing a very high threat.
Spotting the warning signs
At first glance, counterfeit components can look convincing. However, visual inspection often reveals inconsistencies. “Font inconsistencies, unusually shiny seals on supposedly older products, or subtle typos like the wrong EAN code are all red flags,” Alex explains.
Other warning signs include differences in colour, weight, internal components, sloppy solder joints, or missing manufacturer markings. Even small deviations can indicate a fake product.
The real danger behind fake components
The risk goes far beyond appearance. Counterfeit drives and processors often contain substandard or mismatched components. “Some drives have been found to contain mismatched components, incapable of handling the required power, potentially damaging nearby motors or systems,” . Failures can halt entire production lines, cause significant financial losses, and create serious safety hazards, particularly in high voltage installations.
A growing problem
Obsolescence is a major driver. As OEMs discontinue older models, genuine spare parts become scarce and expensive. This creates opportunities for counterfeiters who clean, reseal, and repackage used parts to resemble new ones. At the same time, strong demand for new components makes it easier for fraudulent vendors to pass off used or fake parts as new.
Staying protected
The most frequently counterfeited products include PLCs, HMI panels, and frequency drives from well known brands. With high unit prices, the incentive for fraud is significant. Our advice is straightforward: do not buy from websites like Ebay or individuals on the internet , buy from companies in the EU and UK area to stay protected. “As counterfeiters become more sophisticated, businesses must match them with equally sophisticated procurement and quality control practices,” he concludes. In an industry where reliability and safety are critical, vigilance is essential. Preventing counterfeit components from entering your supply chain is not just about cost control. It is about protecting your operations, your people, and your reputation.
