The consequences of counterfeit electronic components in aerospace and defense applications are categorically different from commercial electronics. A counterfeit component in a smartphone is an inconvenience. A counterfeit component in an aircraft flight control system or a missile guidance unit is a potential catastrophe. This stakes difference explains why the aerospace and defense industry has developed the most rigorous counterfeit prevention standards in any commercial sector β and why compliance with these standards is increasingly a contractual requirement for anyone in the defense supply chain.
The Regulatory Framework
The primary standards governing counterfeit electronic part avoidance in aerospace and defense are SAE International’s AS5553 (Fraudulent/Counterfeit Electronic Parts: Avoidance, Detection, Mitigation, and Disposition) and AS6171 (Test Methods Standard: Counterfeit Electronic Parts). These standards were developed collaboratively by aerospace OEMs, Tier 1 contractors, distributors, and testing laboratories to create a common framework for counterfeit risk management across the supply chain.
Compliance with AS5553 is mandated by DFARS 252.246-7008, the US Department of Defense’s defense acquisition regulation on counterfeit parts avoidance, for companies supplying electronic systems to the US military. Similar requirements exist in UK Defence Standard 05-135 and NATO standards. The National Defense Authorization Act (NDAA) has also addressed counterfeit electronics specifically, creating legal liability for defense contractors who knowingly use or fail to report counterfeit parts.
AS5553 Key Requirements
AS5553 establishes a risk-based framework for counterfeit avoidance that covers the full procurement lifecycle. Key requirements include: sourcing preference for OCMs (Original Component Manufacturers) and authorized distribution; documented process for evaluating and approving independent distributors; incoming inspection and testing requirements commensurate with risk level; documented disposition process for suspect-counterfeit parts; and mandatory reporting of confirmed counterfeits to GIDEP (Government-Industry Data Exchange Program).
The standard takes a risk-tiered approach β the rigor of inspection required scales with the risk level of the procurement, which in turn is based on factors like the application criticality, the availability of the part from authorized sources, and the age and traceability of the specific lot being purchased.
AS6171 Testing Methods
AS6171 provides the specific test method standards that laboratories use to evaluate suspect-counterfeit components. Test families include: physical/dimensional inspection, X-ray fluorescence (XRF) analysis, scanning electron microscopy (SEM), acoustic microscopy (C-SAM), electrical characterization, and destructive physical analysis (DPA) including decapsulation. The standard provides guidance on when each test type is appropriate and what acceptance criteria should apply.
Companies subject to AS5553 requirements typically either build in-house inspection capabilities for the most common test types or partner with accredited independent test laboratories (ITLs) β such as Oneida Research Services, IDEA, or DLA-accredited labs β for higher-complexity testing.
Building a Compliant Program
For companies new to AS5553 compliance, the path forward starts with a gap assessment against the standard requirements, followed by documented procedure development, training of procurement and quality personnel, and β if using independent distributors β supplier qualification against the standard’s distributor requirements. Third-party certification to AS5553 is increasingly expected by prime contractors, even when not strictly mandated.
