RT0805FRE07665KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07665KL is a 665 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching resistance value, package format, power rating, and operating temperature specifications to ensure direct functional compatibility in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE07665KL are qualified based on the following mandatory parameters:

• Resistance value: 665 kOhms (exact match required)
• Package format: 0805 (2012 Metric) with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm)
• Power rating: 0.125W (1/8W) minimum
• Operating temperature range: -55°C to 155°C (minimum coverage required)
• Composition: Thin film construction
• Termination count: 2 terminations
• Compliance: RoHS3 compliant, REACH unaffected

The ERA-6AEB6653V qualifies as a direct substitute based on these parameters. While this part offers enhanced tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance improvements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE07665KL and ERA-6AEB6653V maintain Active product status with full regulatory compliance (RoHS3, REACH unaffected). The ERA-6AEB6653V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Selection between these parts depends on application requirements: the YAGEO part is suitable for general industrial and commercial applications, while the Panasonic part is specified for automotive and high-reliability environments where tighter tolerance and lower temperature coefficient are beneficial.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB6653V directly replace the RT0805FRE07665KL in existing designs?

A: Yes. Both parts share identical resistance value (665 kOhms), power rating (0.125W), package format (0805), operating temperature range (-55°C to 155°C), and physical dimensions. The ERA-6AEB6653V offers superior tolerance and temperature stability, making it a direct functional substitute.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance specifies the maximum deviation from the nominal resistance value. The ±0.1% tolerance of the ERA-6AEB6653V provides tighter resistance accuracy compared to the ±1% tolerance of the RT0805FRE07665KL. Applications requiring precise resistance values benefit from the tighter tolerance specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts conform to the 0805 (2012 Metric) package standard with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on PCB layouts designed for 0805 components.

Q: What does AEC-Q200 qualification mean for the ERA-6AEB6653V?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability for automotive applications. The ERA-6AEB6653V meets this standard, making it suitable for automotive and high-reliability applications where enhanced quality assurance is required.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RT0805FRE07665KL and ERA-6AEB6653V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
