Substitute Part Grouping Explanation

Substitution validity is determined by strict equivalence across the following parameters: resistance value (931 Ohms), package type (0402 / 1005 Metric), power rating (0.063W / 1/16W), operating temperature range (-55°C ~ 155°C), composition (thin film), and physical dimensions (0.039" L x 0.020" W). Substitute parts identified in this reference maintain all these core parameters. Tolerance specifications may vary (±1%, ±0.5%, ±0.1%), and temperature coefficient values differ by manufacturer. All substitute parts listed are Active status with ROHS3 compliance.

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance. Selection between RT0402FRE07931RL and substitute options depends on tolerance and temperature coefficient requirements for the application circuit.

RT0402BRD07931RL and RT0402DRD07931RL offer tighter tolerance specifications (±0.1% and ±0.5% respectively) within the YAGEO RT series, with improved temperature coefficient performance (±25ppm/°C) compared to the base part (±50ppm/°C).

CPF0402B931RE1 provides TE Connectivity sourcing with ±0.1% tolerance and ±25ppm/°C temperature coefficient, maintaining identical package dimensions and height specifications.

ERA-2AEB9310X is qualified to Automotive AEC-Q200 standard and manufactured by Panasonic. This part carries automotive-grade certification and exhibits a maximum seated height of 0.016" (0.40mm), which is 0.002" greater than other options.

RN73C1E931RBTDF from TE Connectivity offers the lowest temperature coefficient specification at ±10ppm/°C with ±0.1% tolerance, suitable for precision applications requiring minimal thermal drift.
