RT0402FRE076K65L Equivalent & Substitute Parts

Part Overview

The RT0402FRE076K65L is a 6.65 kOhms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, design upgrades, or performance optimization needs.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Resistance Value: Must be 6.65 kOhms
Package Type: Must be 0402 (1005 Metric)
Composition: Must be Thin Film
Power Rating: Must be 0.063W (1/16W) minimum
Termination Count: Must be 2
RoHS Compliance: Must be ROHS3 Compliant
MSL Rating: Must be 1 (Unlimited)
Operating Temperature Range: Must support -55°C to 155°C minimum

Tolerance and temperature coefficient variations are permitted within the substitute group, as these represent performance enhancements or alternative specifications that do not compromise circuit functionality when the primary electrical and mechanical parameters remain constant.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection between RT0402FRE076K65L and its substitutes is based on the following criteria:

RT0402BRD076K65L and RT0402BRE076K65L (YAGEO): These parts offer improved tolerance (±0.1% versus ±1%) while maintaining identical package dimensions and operating temperature range. RT0402BRD076K65L provides tighter temperature coefficient (±25ppm/°C). Both are direct upgrades in precision specification.

CPF0402B6K65E1 (TE Connectivity Passive Product): Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with identical package and thermal specifications. Neohm series designation indicates specialized thin film construction.

ERA-2AEB6651X (Panasonic Electronic Components): Provides ±0.1% tolerance with AEC-Q200 automotive qualification. Height-seated maximum is 0.40mm versus 0.35mm for YAGEO parts. Suitable for automotive applications requiring AEC-Q200 certification.

RR0510P-6651-D (Susumu): Offers ±0.5% tolerance with ±25ppm/°C temperature coefficient. Operating temperature range is -55°C to 125°C, which is 30°C lower than the main part. Height-seated maximum is 0.40mm. Selection requires verification that the reduced upper temperature limit (-125°C versus 155°C) is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD076K65L replace RT0402FRE076K65L directly?

A: Yes. Both parts share identical resistance (6.65 kOhms), package (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). RT0402BRD076K65L provides superior tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0402BRD076K65L and RT0402BRE076K65L?

A: Both parts have ±0.1% tolerance and identical package specifications. The primary difference is temperature coefficient: RT0402BRD076K65L is ±25ppm/°C while RT0402BRE076K65L is ±50ppm/°C. Selection depends on thermal stability requirements.

Q: Is ERA-2AEB6651X compatible with the original RT0402FRE076K65L?

A: ERA-2AEB6651X is mechanically and electrically compatible. The seated height maximum is 0.40mm versus 0.35mm for RT0402FRE076K65L. Verify PCB layout clearance before substitution. ERA-2AEB6651X includes AEC-Q200 automotive qualification, which is not required for non-automotive applications.

Q: Can RR0510P-6651-D be used as a substitute?

A: RR0510P-6651-D is compatible for applications where the operating temperature range does not exceed 125°C. The original part supports -55°C to 155°C, while RR0510P-6651-D supports -55°C to 125°C. Verify that the application's maximum operating temperature does not exceed 125°C before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including the main part RT0402FRE076K65L and all substitutes, maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of tolerance differences?

A: Tolerance specifies the acceptable resistance deviation from the nominal 6.65 kOhms value. RT0402FRE076K65L allows ±1% deviation (6.54–6.76 kOhms), while substitute parts with ±0.1% tolerance allow only ±0.0067 kOhms deviation (6.64–6.66 kOhms). Tighter tolerance is beneficial for precision analog circuits but is not required for general-purpose applications.
