TNPW080591R0BEEA Equivalent & Substitute Parts

Part Overview

The TNPW080591R0BEEA is a 91 Ohm ±0.1% thin film chip resistor manufactured by Vishay Dale in 0805 (2012 Metric) package format. This component is rated for 0.26W power dissipation and is designed for automotive applications with AEC-Q200 qualification, anti-sulfur coating, and moisture resistance. The part is currently in active production status with 959 units available in inventory. Equivalent and substitute parts are identified when circuit designs require alternative sourcing due to supply constraints, lead time considerations, or design flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TNPW080591R0BEEA are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 91 Ohms
• Tolerance: ±0.1%
• Temperature coefficient: ±25ppm/°C
• Composition: Thin Film

Mechanical Parameters (Must Match):

• Package format: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance & Environmental (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range capability

Power Rating Consideration: Substitute parts with equal or greater power rating (≥0.26W) are acceptable. Parts with lower power ratings (0.125W) may be used in applications where circuit design confirms power dissipation does not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB910V (Panasonic Electronic Components): This part is a direct substitute for automotive applications. It maintains AEC-Q200 qualification, identical electrical specifications (91 Ohms ±0.1%, ±25ppm/°C), and matching 0805 package dimensions. The operating temperature range extends to 155°C (versus 175°C for the main part). Power rating is 0.125W; circuit design must confirm that actual power dissipation does not exceed this value. Inventory availability is 28,688 units.

RT0805BRD0791RL (YAGEO): This part matches all electrical parameters and package specifications. It is ROHS3 compliant with MSL 1 rating. The operating temperature range is -55°C ~ 155°C. This part does not carry AEC-Q200 automotive qualification. Power rating is 0.125W; circuit design must confirm that actual power dissipation does not exceed this value. Inventory availability is 6,000 units.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB910V or RT0805BRD0791RL be used as direct replacements for TNPW080591R0BEEA?

A: Both parts are electrically and mechanically compatible. ERA-6AEB910V maintains AEC-Q200 automotive qualification. RT0805BRD0791RL does not carry automotive qualification. Both have lower power ratings (0.125W versus 0.26W); substitution is valid only if circuit analysis confirms actual power dissipation remains below 0.125W.

Q: What is the impact of the lower power rating on the substitute parts?

A: Power rating defines maximum continuous power dissipation. If the circuit design requires sustained power dissipation above 0.125W, the substitute parts are not suitable. If actual dissipation is below 0.125W, the lower rating does not affect performance.

Q: Are there temperature range differences between the main part and substitutes?

A: The main part operates to 175°C; both substitutes operate to 155°C. If the application requires operation above 155°C, the substitutes are not suitable. For applications within -55°C ~ 155°C, the substitutes are compatible.

Q: Does package height variation matter?

A: The main part height is 0.022" (0.55mm); substitutes are 0.024" (0.60mm). This 0.002" difference is within typical PCB assembly tolerances for 0805 components. Verify clearance in specific board designs if height-constrained applications exist.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors. ERA-6AEB910V carries this qualification; RT0805BRD0791RL does not. For automotive applications requiring AEC-Q200 compliance, ERA-6AEB910V is the appropriate substitute.

Q: Are all three parts RoHS3 compliant?

A: Yes. TNPW080591R0BEEA, ERA-6AEB910V, and RT0805BRD0791RL are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
