RT0402FRE07681RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07681RL is a 681 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and active product status. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while allowing variations in tolerance, temperature coefficient, and manufacturer-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0402FRE07681RL is permissible when the following core parameters remain constant:

• Resistance value: 681 Ohms
• Package / Case: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Termination count: 2
• Packaging format: Tape & Reel (TR)

Tolerance, temperature coefficient, operating temperature range, and manufacturer-specific certifications (such as AEC-Q200) may vary. All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct PCB compatibility and functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions. Selection between substitutes depends on application-specific tolerance and temperature requirements:

RT0402BRD07681RL and CPF0402B681RE1 offer improved tolerance (±0.1%) compared to the original part (±1%), with lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). These are suitable for precision applications requiring tighter resistance stability.

ERA-2AEB6810X includes AEC-Q200 automotive qualification, appropriate for automotive and high-reliability applications. Operating temperature range matches the original specification (-55°C ~ 155°C).

RR0510P-6810-D from Susumu provides ±0.5% tolerance with ±25ppm/°C temperature coefficient. Operating temperature range is limited to -55°C ~ 125°C, making it suitable for applications not requiring the full 155°C upper limit.

All parts are active products with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07681RL replace RT0402FRE07681RL directly on the PCB?

A: Yes. Both parts share identical 0402 package dimensions, 681 Ohm resistance, and 0.063W power rating. RT0402BRD07681RL offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient, making it a direct upgrade with improved performance characteristics.

Q: What is the difference between ERA-2AEB6810X and other substitutes?

A: ERA-2AEB6810X is qualified to AEC-Q200 automotive standard, distinguishing it for automotive applications. All other electrical and mechanical parameters align with standard industrial-grade substitutes. Height when seated is 0.016" (0.40mm) versus 0.014" (0.35mm) for the original part, remaining within typical PCB assembly tolerances.

Q: Is RR0510P-6810-D suitable for all applications using RT0402FRE07681RL?

A: RR0510P-6810-D is suitable for applications operating within -55°C to 125°C. Applications requiring operation at temperatures between 125°C and 155°C require alternative substitutes. All other electrical specifications and package dimensions are compatible.

Q: Do all substitutes maintain the same moisture sensitivity level?

A: Yes. All identified substitutes carry MSL 1 (Unlimited) rating, matching the original part. Storage and handling requirements are identical across all parts.

Q: Are there tolerance considerations when selecting a substitute?

A: Tolerance selection depends on circuit requirements. The original RT0402FRE07681RL specifies ±1%. Substitutes offering ±0.1% (RT0402BRD07681RL, CPF0402B681RE1, ERA-2AEB6810X) provide tighter tolerance for precision applications. RR0510P-6810-D offers intermediate ±0.5% tolerance. Verify circuit design specifications before selection.
