RT0402FRE07665RL Equivalent & Substitute Parts
Part Overview
The RT0402FRE07665RL is a 665 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant with MSL 1 rating.
Substitute parts are identified when they maintain identical electrical specifications (resistance value, package, power rating, operating temperature range) while offering improved tolerance, temperature coefficient, or enhanced certifications. Alternative sources ensure supply continuity and may provide performance upgrades for precision applications.

Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence in the following parameters:
- Resistance value: 665 Ohms (exact match required)
- Package: 0402 (1005 Metric) (exact match required)
- Power rating: 0.063W, 1/16W (exact match required)
- Operating temperature range: -55°C to 155°C (exact match required)
- Composition: Thin Film (exact match required)
- Number of terminations: 2 (exact match required)
Substitute parts identified below meet all core electrical and mechanical requirements. Variations in tolerance, temperature coefficient, and certifications represent performance enhancements or application-specific qualifications rather than functional incompatibilities.

Engineering Selection Recommendations
All identified substitute parts maintain Active product status and ROHS3 compliance. Selection among equivalents depends on application-specific requirements:
RT0402BRD07665RL (YAGEO) provides improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) while maintaining the same manufacturer and package ecosystem.
CPF0402B665RE1 (TE Connectivity Passive Product) offers equivalent tolerance and temperature coefficient performance with alternative manufacturer sourcing for supply diversification.
ERA-2AEB6650X (Panasonic Electronic Components) includes Automotive AEC-Q200 qualification, suitable for automotive and high-reliability applications requiring automotive-grade components.
RG1005V-6650-P-T1 (Susumu) provides the highest precision tolerance (±0.02%) and lowest temperature coefficient (±5ppm/°C), with Anti-Sulfur and Automotive AEC-Q200 features for demanding precision and automotive environments.
Frequently Asked Questions (FAQ)
Q: Can RT0402BRD07665RL directly replace RT0402FRE07665RL?
A: Yes. Both parts share identical resistance (665 Ω), package (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). RT0402BRD07665RL offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C).
Q: What is the difference between standard and automotive-qualified substitutes?
A: ERA-2AEB6650X and RG1005V-6650-P-T1 carry Automotive AEC-Q200 qualification. This certification indicates compliance with automotive reliability and environmental stress testing standards. Use automotive-qualified parts in automotive applications or systems requiring automotive-grade component reliability.
Q: Are all substitutes available in the same packaging format?
A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging in 0402 (1005 Metric) format, matching the original part's packaging specification.
Q: Which substitute offers the best tolerance and temperature stability?
A: RG1005V-6650-P-T1 provides ±0.02% tolerance and ±5ppm/°C temperature coefficient, representing the highest precision among identified substitutes.
Q: Can substitutes be mixed in the same production batch?
A: All substitutes meet identical core electrical and mechanical specifications. However, verify with your quality and procurement procedures regarding multi-source component usage in production environments.
