RT0805CRE0791RL Equivalent & Substitute Parts

Part Overview

The RT0805CRE0791RL is a 91 Ohm thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount device delivers 0.125W (1/8W) power dissipation with ±0.25% tolerance and operates across -55°C to 155°C. The part is ROHS3 compliant and carries MSL 1 rating, indicating unlimited moisture sensitivity protection. As an active product with established supply availability, substitute parts are identified for applications requiring enhanced tolerance specifications or automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE0791RL 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 specifications:

1. RT0805BRD0791RL (YAGEO): Tighter tolerance (±0.1% vs ±0.25%) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C)
2. ERA-6AEB910V (Panasonic): Tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), and automotive AEC-Q200 qualification

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0791RL is suitable for applications requiring improved tolerance and temperature stability within standard industrial environments. Both substitute parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

ERA-6AEB910V is specified for automotive applications requiring AEC-Q200 qualification. This part provides identical electrical performance to RT0805BRD0791RL with additional automotive-grade reliability certification.

Selection between the main part and substitutes depends on application tolerance requirements and environmental qualification needs, not on electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0791RL replace RT0805CRE0791RL in any application?

A: Yes. Both parts share identical resistance, power rating, package, and operating temperature range. RT0805BRD0791RL offers tighter tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for precision applications.

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

A: Both provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. ERA-6AEB910V carries AEC-Q200 automotive qualification; RT0805BRD0791RL does not. Electrical performance is equivalent.

Q: Is ERA-6AEB910V compatible with standard PCB assembly processes?

A: Yes. ERA-6AEB910V maintains 0805 package dimensions, 2 terminations, MSL 1 rating, and ROHS3 compliance. No assembly process modifications are required.

Q: Can the main part RT0805CRE0791RL be used in automotive applications?

A: RT0805CRE0791RL is not AEC-Q200 qualified. For automotive applications, ERA-6AEB910V is the appropriate selection.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. RT0805CRE0791RL, RT0805BRD0791RL, and ERA-6AEB910V are all supplied in Tape & Reel (TR) packaging.
