RT0402FRE079K76L Equivalent & Substitute Parts

Part Overview

The RT0402FRE079K76L is a 9.76 kOhms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This component is rated for 0.063W (1/16W) power dissipation with a temperature coefficient of ±50ppm/°C and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status.

Substitute parts are identified based on matching the core electrical specifications: 9.76 kOhms resistance value, 0402 package format, 0.063W power rating, and thin film composition. Alternatives are available with improved tolerance grades (±0.5% and ±0.1%) and enhanced temperature coefficients, as well as automotive-qualified variants meeting AEC-Q200 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance Value: Must be 9.76 kOhms (exact match)
• Package Format: Must be 0402 (1005 Metric)
• Power Rating: Must be 0.063W (1/16W)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Termination Count: Must be 2 terminations
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories:

Category A - Standard Industrial Grade: Parts with tolerance grades of ±0.5% or ±1%, suitable for general industrial applications.

Category B - Precision & Automotive Grade: Parts with tolerance grades of ±0.1%, including automotive AEC-Q200 qualified variants with enhanced reliability for automotive and high-precision applications.

All substitute parts maintain identical physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and electrical operating parameters as the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): RT0402DRE079K76L (YAGEO) provides the closest match with identical temperature coefficient (±50ppm/°C) while offering improved tolerance (±0.5% vs ±1%). This part maintains the same operating characteristics as the original with enhanced precision.

For Improved Tolerance Applications: RT0402DRD079K76L (YAGEO) offers ±0.5% tolerance with reduced temperature coefficient (±25ppm/°C), suitable for circuits requiring tighter resistance accuracy without automotive qualification requirements.

For Precision Circuit Design: CPF0402B9K76E1 (TE Connectivity Passive Product) and RN73C1E9K76BTDF (TE Connectivity Passive Product) both provide ±0.1% tolerance. RN73C1E9K76BTDF features the lowest temperature coefficient (±10ppm/°C) for applications demanding maximum stability across temperature ranges.

For Automotive Applications: ERA-2AEB9761X (Panasonic Electronic Components) and RG1005P-9761-B-T5 (Susumu) are both AEC-Q200 qualified. RG1005P-9761-B-T5 includes anti-sulfur protection, recommended for harsh automotive environments.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRE079K76L be used as a direct replacement for RT0402FRE079K76L?

A: Yes. Both parts share identical resistance (9.76 kOhms), package (0402), power rating (0.063W), and operating temperature range (-55°C ~ 155°C). RT0402DRE079K76L offers improved tolerance (±0.5% vs ±1%) and identical temperature coefficient (±50ppm/°C), making it a compatible upgrade.

Q: What is the difference between tolerance grades ±1%, ±0.5%, and ±0.1%?

A: Tolerance specifies the maximum deviation from the nominal resistance value. ±1% allows ±97.6 Ohms deviation; ±0.5% allows ±48.8 Ohms; ±0.1% allows ±9.76 Ohms. Tighter tolerances are required for precision analog circuits, measurement equipment, and high-accuracy signal conditioning.

Q: Are automotive-qualified parts (AEC-Q200) compatible with industrial applications?

A: Yes. AEC-Q200 qualification exceeds industrial requirements and ensures enhanced reliability through rigorous testing. ERA-2AEB9761X and RG1005P-9761-B-T5 can be used in any application where the original part is specified, with added reliability margin.

Q: What does temperature coefficient (ppm/°C) indicate?

A: Temperature coefficient specifies resistance change per degree Celsius. ±50ppm/°C means 0.005% change per °C; ±10ppm/°C means 0.001% change per °C. Lower values indicate better stability across temperature extremes, critical for precision circuits and wide-temperature-range applications.

Q: Can I substitute parts with different packaging (Tape & Reel vs Cut Tape)?

A: Packaging format (Tape & Reel vs Cut Tape) affects supply and handling only. Electrical and mechanical specifications remain identical. Selection depends on assembly process requirements and order quantities, not circuit compatibility.

Q: Is RoHS3 compliance maintained across all substitute parts?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.

Q: Which substitute offers the best temperature stability?

A: RN73C1E9K76BTDF features the lowest temperature coefficient at ±10ppm/°C, providing superior resistance stability across the -55°C ~ 155°C operating range. This part is recommended for applications requiring maximum thermal stability.
