This paper will present the assessment of automotive qualified components for Space applications being performed in the frame of ESA Contract 4000126343/19/NL/hh. The proposed work to be performed includes a full thermomechanical and endurance evaluation (2000h life test, 500 cycles -55ºC to +125ºC thermal cycling, HAST or THB) along with constructional analysis and measurements of Tg (glass transition temperature) and outgassing. These tests will be done on three different lots separated by years of lot date codes on three selected AEC-Q candidates (total 9 lots). This testing will allow to confirm manufacturing stability (die mask, assembly techniques, moulding material, etc….) and process variability over time. The three candidates are selected from non-radiation sensitive devices of an “AEC Space PPL” List already compiled from the comparison of what is offered as AEC qualified (AEC QPL list with >200K items) and what is more demanded for Space (Space PPL list from ESCC QPL/QML/PPL, NASA NPSL/GSFC PPL, etc.. with 1500 items).
