RT0603FRE0797K6L Equivalent & Substitute Parts

Part Overview

The RT0603FRE0797K6L is a 97.6 kOhms ±1% thin film chip resistor in 0603 (1608 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.1W (1/10W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, making it suitable for general industrial and commercial applications. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while offering improved tolerance, temperature coefficient performance, or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Resistance value must equal 97.6 kOhms
• Package must be 0603 (1608 Metric)
• Power rating must be ≥0.1W
• Composition must be thin film
• Operating temperature range must encompass -55°C ~ 155°C
• RoHS3 compliance required
• MSL rating must be ≤1

Tolerance and temperature coefficient may vary within acceptable engineering margins. Automotive-grade certifications (AEC-Q200) and enhanced tolerance specifications represent performance upgrades. Physical dimensions must remain compatible with 0603 package specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with the original RT0603FRE0797K6L in standard PCB assembly processes.

RT0603BRD0797K6L (YAGEO) provides improved tolerance (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. This represents a direct performance upgrade from the same manufacturer.

8-2176089-9 (TE Connectivity) offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with increased power rating (0.167W vs 0.1W), providing thermal margin in power-constrained applications.

ERA-3AEB9762V (Panasonic) combines ±0.1% tolerance with AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability without anti-sulfur protection.

RG1608P-9762-D-T5 (Susumu) provides AEC-Q200 automotive qualification with anti-sulfur protection and ±25ppm/°C temperature coefficient. Tolerance is ±0.5%, which remains within acceptable substitution parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0797K6L replace RT0603FRE0797K6L in any application?

A: Yes. RT0603BRD0797K6L maintains identical resistance, power rating, package, and operating temperature range. The improved tolerance and temperature coefficient represent performance enhancements with no compatibility concerns.

Q: What is the difference between the TE Connectivity 8-2176089-9 and the original part?

A: The TE Connectivity part offers ±0.1% tolerance (vs ±1%), ±25ppm/°C temperature coefficient (vs ±50ppm/°C), and higher power rating (0.167W vs 0.1W). Physical dimensions are 0.061" L × 0.031" W (vs 0.063" L × 0.031" W), remaining within 0603 package specifications.

Q: Are the Panasonic ERA-3AEB9762V and Susumu RG1608P-9762-D-T5 suitable for automotive applications?

A: Both parts carry AEC-Q200 automotive qualification. ERA-3AEB9762V is suitable for standard automotive environments. RG1608P-9762-D-T5 includes anti-sulfur protection for applications exposed to corrosive atmospheres.

Q: Does tolerance affect PCB assembly compatibility?

A: No. All substitute parts use identical 0603 (1608 Metric) package with compatible termination specifications. Tolerance differences affect circuit performance precision, not physical assembly.

Q: Can I use a substitute part with higher power rating in a design rated for 0.1W?

A: Yes. Parts with higher power ratings (such as 8-2176089-9 at 0.167W) are backward compatible and provide additional thermal margin. No design modification is required.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts share this rating, ensuring identical storage and handling procedures.
