Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE0786R6L are qualified based on the following criteria:

• Resistance Value: Exact match at 86.6 Ohms
• Package / Case: Identical 0402 (1005 Metric) form factor
• Power Rating: Equal or greater than 0.063W (1/16W)
• Composition: Thin film construction
• Operating Temperature Range: Minimum coverage of -55°C ~ 155°C
• Termination Count: 2 terminations (standard SMD configuration)
• RoHS Compliance: ROHS3 Compliant

The identified substitutes meet or exceed these parameters. Tolerance and temperature coefficient variations are noted as performance differentiators but do not disqualify substitution in applications where the main part's specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

RT0402FRE0786R6L (YAGEO): Primary choice for standard applications requiring ±1% tolerance. Active product status with 961 units in stock. Suitable for general-purpose analog circuits where the specified tolerance and temperature coefficient are acceptable.

ERA-2AEB86R6X (Panasonic): Upgrade option offering ±0.1% tolerance and ±25ppm/°C temperature coefficient. Qualified to AEC-Q200 automotive standard, indicating enhanced reliability and process control. Highest inventory availability at 3624 units. Recommended for precision applications and automotive-grade designs where tighter tolerance is required.

RN73C1E86R6BTDF (TE Connectivity): Premium option with ±0.1% tolerance and ±10ppm/°C temperature coefficient, the lowest temperature coefficient among the three options. Suitable for high-precision measurement and signal conditioning circuits. Limited inventory at 635 units.

All three parts are ROHS3 compliant, MSL 1 rated, and mechanically compatible with 0402 PCB footprints. Selection should be based on tolerance requirements, temperature stability needs, and application-specific reliability standards.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEB86R6X or RN73C1E86R6BTDF be used as direct replacements for RT0402FRE0786R6L?

A: Yes. All three parts share identical resistance values (86.6 Ohms), package form factor (0402), power rating (0.063W), and operating temperature range (-55°C ~ 155°C). The substitute parts offer improved tolerance (±0.1% vs. ±1%) and lower temperature coefficients, making them electrically compatible and functionally superior in precision applications.

Q: What is the impact of tolerance differences on circuit performance?

A: The RT0402FRE0786R6L has ±1% tolerance, while ERA-2AEB86R6X and RN73C1E86R6BTDF have ±0.1% tolerance. In applications where resistor accuracy directly affects circuit gain, frequency response, or measurement precision, the tighter tolerance of the substitute parts reduces circuit-level error. For general-purpose applications, ±1% tolerance is typically sufficient.

Q: Are there height clearance concerns when substituting these parts?

A: The RT0402FRE0786R6L and RN73C1E86R6BTDF have a maximum seated height of 0.014" (0.35mm), while ERA-2AEB86R6X is 0.016" (0.40mm). This 0.002" (0.05mm) difference is negligible for most PCB designs. Verify clearance only if the application has strict height constraints (e.g., stacked components or confined spaces).

Q: Which substitute part is recommended for automotive applications?

A: ERA-2AEB86R6X is qualified to AEC-Q200 automotive standard, making it the appropriate choice for automotive-grade designs. The other parts do not carry automotive certification.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance value drift with temperature. RT0402FRE0786R6L has ±50ppm/°C, ERA-2AEB86R6X has ±25ppm/°C, and RN73C1E86R6BTDF has ±10ppm/°C. Lower temperature coefficients provide better stability across the operating temperature range (-55°C ~ 155°C), critical for precision analog circuits and temperature-sensitive applications.
