Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (2 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (AEC-Q200, ROHS3). Parts are grouped into three categories based on product availability and certification status:

Direct Equivalents (Active Status): Parts with identical specifications and active product status from major manufacturers.

Direct Equivalents (Discontinued Status): Parts meeting all electrical and mechanical specifications but with discontinued availability status.

Upgrade Option: Parts exceeding base specifications with improved tolerance (±0.5%) while maintaining all other parameters.

Similar Parts: Components with identical core specifications but lacking automotive AEC-Q200 certification or featuring alternative material properties.
