Abstract: The electronic components are the basic element of astronautic products, so it needs to develop a solid foundation to guarantee the quality and reliability of products in a better and faster direction. Due to the rigorous validation during early stage and long service lifecycle in later period for astronautic engineering, it is crucial to control the selection of electronic components. In order to meet the specific requirements of astronautic products, this paper provides a comprehensive exploration of component selection and its control methods by considering the deduction design, quality level, and spatial applicability. In addition, from a point of operational reliability, the control strategies of component selection are summarized for some classical components, such as integrated circuit, diode, resistor, photoelectric device, electric relay, capacitor, and electrical connector, as well as the customized components. By using these selection strategies, it can contribute to guaranteeing the operational reliability and thus integrally improving the quality and reliability of astronautic products.
