AECQ200

AECQ200 is a standard developed by the Automotive Electronics Council that specifies the qualification requirements for passive components used in automotive electronics. It defines the environmental and reliability tests, along with acceptance criteria, needed to demonstrate that components can withstand the harsh conditions of automotive service.

The scope of AECQ200 covers passive components such as resistors, capacitors, and inductors that are intended for automotive use. It applies to components manufactured to meet automotive reliability requirements and incorporated into electronic modules and systems. The standard helps distinguish automotive-grade passive parts from general-purpose components used outside of automotive environments.

The qualification framework in AECQ200 outlines a set of stress tests and evaluation criteria. This includes thermal exposure and cycling, humidity and bias tests, mechanical shock and vibration, as well as electrical bias tests and terminal strength assessments. The standard also specifies sampling plans, failure criteria, and processes for maintaining traceability. If a qualified component or supplier changes in a way that could affect reliability, requalification is typically required.

In practice, AECQ200 is used by component manufacturers and automotive suppliers to demonstrate reliability for automotive applications. Many automakers and tiered suppliers require components to be qualified to AECQ200 as part of procurement. The standard is one of several automotive reliability specifications and is often considered alongside AEC-Q100 for semiconductors and other related standards, with updates issued to address evolving technologies.
