This paper presents a market analysis of automotive components. The purpose of this study is to identify components in automotive temperature range in order to use into spacecraft programs. The study has shown that the standard commercial component approach, i.e. risk analysis and justification document, is applicable to most of the components, called 'automotive', in -40 deg C/+125 deg C temperature range. In Texas Instruments case the authors will use the components, which are qualified according Q-100 standard, without complementary test. Nevertheless a Destructive Physical Analysis on all the supplied lots will be required in order to avoid potential maverick lots. After negotiation, STMicroelectronics can propose a Q-100 qualification on some products. Then the approach will be similar. In all the cases an electrical characterisation over the temperature range will be necessary if the parameters are not guaranteed in the datasheet. To conclude, Automotive components show a specific interest for space applications, as their quality and reliability requirements are comparable with space application ones. The next step, after this market analysis, will be to know radiation behaviour of the selected components. As the authors intend to use some of these parts on PLEIADES space project, a Total lonising Dose test is planned on the LM2901 from STMicroelectronics and on the TLC2274 from Texas Instruments. A Heavy Ions test will be also performed on the TLC2274 in order to assess its susceptibility to Single Event Latch-up.
