Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance Value: Must be 91 Ohms
• Tolerance: Must be ±0.1%
• Package Type: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Compliance: Must maintain ROHS3 and MSL 1 ratings

The identified substitute parts meet these core electrical and mechanical requirements. Power rating differences are noted where they occur, as lower-rated substitutes may be acceptable in applications with reduced power dissipation requirements.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB910V (Panasonic Electronic Components): This substitute maintains AEC-Q200 automotive qualification and identical electrical specifications. The reduced power rating (0.125W vs. 0.26W) is acceptable for applications where power dissipation does not exceed 0.125W. Operating temperature range is limited to -55°C ~ 155°C compared to the original -55°C ~ 175°C. Selection is appropriate for standard automotive and industrial circuits within the specified thermal envelope.

RT0805BRD0791RL (YAGEO): This substitute provides identical electrical parameters and package specifications. The part lacks explicit AEC-Q200 certification; applications requiring automotive qualification should reference YAGEO documentation for compliance verification. Power rating is 0.125W, with operating temperature range of -55°C ~ 155°C. This option is suitable for non-automotive applications or where automotive certification is not mandated.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB910V be used in place of TNPW080591R0BEEN in all applications?

A: ERA-6AEB910V is electrically compatible for circuits where power dissipation does not exceed 0.125W. If the circuit requires operation above 155°C, the original part's extended temperature range (-55°C ~ 175°C) is necessary. Both parts carry AEC-Q200 certification and MSL 1 rating.

Q: What is the significance of the power rating difference?

A: The TNPW080591R0BEEN is rated for 0.26W, while both substitutes are rated for 0.125W. Power dissipation in a resistor is calculated as P = I²R or P = V²/R. If circuit analysis confirms power dissipation remains below 0.125W, the lower-rated substitutes are acceptable. Exceeding this threshold requires the original part.

Q: Are all three parts suitable for automotive applications?

A: TNPW080591R0BEEN and ERA-6AEB910V both carry AEC-Q200 certification. RT0805BRD0791RL does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, use TNPW080591R0BEEN or ERA-6AEB910V.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts carry this rating, eliminating moisture sensitivity concerns.

Q: Can RT0805BRD0791RL replace TNPW080591R0BEEN in a design requiring -55°C ~ 175°C operation?

A: No. RT0805BRD0791RL is rated only to 155°C maximum. For applications requiring operation up to 175°C, the original TNPW080591R0BEEN or ERA-6AEB910V (if limited to 155°C) must be used.
