Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on substitution relationship to RC1005J202CS:

Direct Substitutes (Tolerance Upgrade): Parts with identical resistance, package, power rating, and operating temperature range but with improved tolerance specification (±1% vs ±5%). These parts maintain full electrical and mechanical compatibility while providing tighter accuracy.

Upgrade Substitutes (Enhanced Features): Parts with identical core specifications but featuring automotive AEC-Q200 qualification or increased power rating (0.1W vs 0.063W). These provide enhanced reliability or thermal margin while maintaining dimensional compatibility.

Similar Substitutes (Tolerance Match): Parts with identical ±5% tolerance and core specifications but featuring automotive AEC-Q200 qualification or anti-sulfur protection. These provide feature enhancement without tolerance change.

Key Parameters Determining Substitution:

Resistance value: 2 kOhms (mandatory match)
Package: 0402 (1005 Metric) (mandatory match)
Operating temperature: -55°C to 155°C (mandatory match)
Temperature coefficient: ±100ppm/°C (mandatory match)
Composition: Thick Film (mandatory match)
Tolerance: ±5% minimum (upgradeable to ±1%)
