Engineering Selection Recommendations
All identified substitute parts maintain active production status and ROHS3 compliance. Selection among substitutes should be based on the following criteria derived from provided specifications:
RT0402DRE0773R2L offers improved tolerance (±0.5%) over the main part while maintaining identical temperature coefficient and YAGEO manufacturer continuity.
CPF0402B73R2E1 and RN73C1E73R2BTDF provide the highest tolerance specification (±0.1%) with reduced temperature coefficients (±25ppm/°C and ±10ppm/°C respectively), suitable for applications requiring tighter resistance stability.
ERA-2AEB73R2X is the only substitute carrying AEC-Q200 automotive qualification, appropriate for automotive and high-reliability applications requiring automotive-grade component certification.
All substitutes are available in Tape & Reel packaging and maintain identical physical dimensions and electrical ratings as the main part.
Frequently Asked Questions (FAQ)
Q: Can RT0402DRE0773R2L replace RT0402FRE0773R2L in any application?
A: Yes. Both parts share identical resistance value (73.2 Ohms), package (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). RT0402DRE0773R2L offers improved tolerance (±0.5% vs ±1%), making it suitable for all applications where the main part is specified.
Q: What is the difference between CPF0402B73R2E1 and ERA-2AEB73R2X?
A: Both parts provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. ERA-2AEB73R2X carries AEC-Q200 automotive qualification and is manufactured by Panasonic, while CPF0402B73R2E1 is manufactured by TE Connectivity. Physical dimensions differ slightly in maximum seated height (0.014" vs 0.016").
Q: Is RN73C1E73R2BTDF compatible with the original part?
A: Yes. RN73C1E73R2BTDF maintains all mandatory parameters: 73.2 Ohms resistance, 0402 package, 0.063W power rating, and -55°C to 155°C operating range. It offers superior temperature coefficient performance (±10ppm/°C) compared to the main part.
Q: Which substitute should be selected for automotive applications?
A: ERA-2AEB73R2X is the appropriate selection for automotive applications, as it is the only substitute carrying AEC-Q200 qualification while maintaining all electrical and mechanical compatibility requirements.
Q: Are all substitutes available in Tape & Reel packaging?
A: Yes. All identified substitutes are supplied in Tape & Reel (TR) packaging, matching the packaging format of the main part RT0402FRE0773R2L.
