Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0791RL is determined by the following critical parameters:

• Resistance Value: Must be 91 Ohms
• Package Type: Must be 0805 (2012 Metric)
• Power Rating: Must be 0.125W (1/8W) minimum
• Composition: Thin film construction
• Operating Temperature Range: Must cover -55°C to 155°C
• Termination Count: 2 terminations required
• Compliance: ROHS3 and MSL 1 minimum

Two substitute parts meet these criteria with enhanced electrical characteristics. RT0805BRD0791RL offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package and power specifications. ERA-6AEB910V provides the same tolerance and temperature coefficient improvements as RT0805BRD0791RL with the addition of automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0791RL is suitable for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C) compared to the original RT0805FRE0791RL. Both components are manufactured by YAGEO and maintain identical package, power, and compliance specifications. This substitute provides direct functional improvement for precision analog circuits.

ERA-6AEB910V is the appropriate selection for automotive applications requiring AEC-Q200 qualification. Manufactured by Panasonic Electronic Components, this part delivers the same tolerance and temperature coefficient performance as RT0805BRD0791RL with automotive-grade reliability certification. The significantly higher inventory level (28688 units) supports extended production runs.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0791RL replace RT0805FRE0791RL in any circuit?

A: Yes. RT0805BRD0791RL is a direct substitute with superior electrical characteristics. The ±0.1% tolerance and ±25ppm/°C temperature coefficient represent improvements over the original ±1% tolerance and ±50ppm/°C specification. All mechanical, thermal, and compliance parameters are identical.

Q: What is the primary difference between RT0805BRD0791RL and ERA-6AEB910V?

A: Both parts share identical electrical specifications (91 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient). ERA-6AEB910V includes AEC-Q200 automotive qualification, making it suitable for automotive applications. RT0805BRD0791RL is the standard industrial-grade equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 0805 (2012 Metric) package with 2 terminations. Physical dimensions, footprint, and soldering requirements are identical across RT0805FRE0791RL, RT0805BRD0791RL, and ERA-6AEB910V.

Q: Which substitute should be selected for high-reliability applications?

A: ERA-6AEB910V is recommended for high-reliability requirements due to AEC-Q200 automotive qualification. For non-automotive precision applications, RT0805BRD0791RL provides equivalent electrical performance with ROHS3 compliance and MSL 1 rating.

Q: Is there a performance penalty when substituting with either part?

A: No. Both substitutes provide equal or superior performance. RT0805BRD0791RL and ERA-6AEB910V offer tighter tolerance and lower temperature coefficient, resulting in improved circuit stability and reduced drift across the operating temperature range.
