• Be Wary of Unusually Low Prices
  Extremely low prices compared to market averages are a major warning sign of counterfeits. If a deal seems too good to be true, it probably is. Counterfeiters often lure buyers with low prices.
• Verify Seller Reputation
  If buying from a marketplace, thoroughly research the seller. Check their feedback, read reviews, and look for patterns of complaints related to counterfeit products. Prioritize sellers with long histories of positive feedback. Look for sellers with clear business information.
• Request Documentation
  Ask for certifications, origin documentation, and testing reports. Legitimate sellers will often provide this documentation to prove the components' authenticity. Be wary if sellers refuse to provide this information, are evasive, or slow to respond.
• Perform Testing
  If possible, perform thorough electrical testing of the components as soon as you receive them. Check for correct electrical characteristics using appropriate testing equipment and compare results with the component's datasheet specifications. If the components fail basic testing, consider them suspect.
• Look for Signs of Refurbishment
  Beware of components that have signs of being used or refurbished, such as scratches, bent pins, or signs of solder residue. New components should appear pristine. Also, observe for any signs of rework or tampering.
• Stay Updated on Counterfeit Alerts
  Stay informed about recent counterfeit alerts by following industry publications and official warnings from manufacturers. This can help you identify common counterfeit patterns.

Shipping Costs, Times and International Considerations

When purchasing electronic components online, understanding the nuances of shipping costs, delivery times, and international shipping policies is crucial.
