RT0402FRE073K65L Equivalent & Substitute Parts

Part Overview

The RT0402FRE073K65L is a 3.65 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 is active and ROHS3 compliant, making it suitable for standard commercial and industrial applications requiring precision resistive elements.

Equivalent and substitute parts are identified when design requirements allow for relaxed tolerance specifications, alternative manufacturers, or enhanced performance characteristics while maintaining identical resistance value, package form factor, and power rating.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE073K65L is determined by the following criteria:

• Identical resistance value: 3.65 kOhms
• Identical package: 0402 (1005 Metric)
• Identical power rating: 0.063W (1/16W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Tolerance equal to or tighter than ±1%
• Active product status
• ROHS3 compliance

Four substitute parts meet these criteria, differentiated by tolerance grade, manufacturer, and temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes depends on application-specific tolerance and temperature stability requirements:

RT0402BRD073K65L (YAGEO) offers tighter tolerance at ±0.1% with improved temperature coefficient of ±25ppm/°C, suitable for applications requiring enhanced precision over the standard ±1% specification.

RT0402DRE073K65L (YAGEO) provides mid-range tolerance at ±0.5%, maintaining the original ±50ppm/°C temperature coefficient while offering a compromise between cost and precision.

ERA-2AEB3651X (Panasonic) delivers ±0.1% tolerance with AEC-Q200 automotive qualification and ±25ppm/°C temperature coefficient, appropriate for automotive and high-reliability applications.

RN73C1E3K65BTDF (TE Connectivity) provides the tightest temperature coefficient specification at ±10ppm/°C with ±0.1% tolerance, optimized for applications with stringent thermal stability requirements.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRE073K65L replace RT0402FRE073K65L in any application?

A: Yes. RT0402DRE073K65L maintains identical resistance, package, power rating, and operating temperature range. The ±0.5% tolerance is tighter than the original ±1%, making it a direct substitute for all applications accepting the original specification.

Q: What is the primary difference between RT0402BRD073K65L and RT0402FRE073K65L?

A: The primary difference is tolerance grade. RT0402BRD073K65L specifies ±0.1% tolerance versus ±1% for RT0402FRE073K65L. Both use identical 0402 packages and power ratings. The tighter tolerance and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) make RT0402BRD073K65L suitable for precision-critical circuits.

Q: Is ERA-2AEB3651X suitable for non-automotive applications?

A: Yes. ERA-2AEB3651X meets all electrical and mechanical requirements for the RT0402FRE073K65L. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in standard commercial or industrial applications.

Q: How does RN73C1E3K65BTDF differ from other substitutes?

A: RN73C1E3K65BTDF is manufactured by TE Connectivity and features the lowest temperature coefficient specification at ±10ppm/°C. This characteristic makes it optimal for applications requiring maximum thermal stability across the -55°C to 155°C operating range.

Q: Are all substitutes available in identical packaging formats?

A: Yes. All substitute parts use 0402 (1005 Metric) package in Tape & Reel (TR) format, ensuring compatibility with standard pick-and-place assembly equipment and PCB footprints designed for the original RT0402FRE073K65L.

Q: Can tolerance grades be mixed within a single circuit design?

A: Tolerance selection depends on circuit requirements. Applications tolerating ±1% variation can use RT0402FRE073K65L or RT0402DRE073K65L. Precision circuits requiring ±0.1% or better should use RT0402BRD073K65L, ERA-2AEB3651X, or RN73C1E3K65BTDF consistently across all resistive elements in the critical signal path.
