TNPW080573R2BEEA Equivalent & Substitute Parts

Part Overview

The TNPW080573R2BEEA is a 73.2 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 active in production with 895 units in stock. Equivalent and substitute parts are identified when identical electrical specifications (resistance value, tolerance, composition, and temperature coefficient) are maintained across the same package format, with allowable variations in power rating and operating temperature range within automotive-grade standards.

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW080573R2BEEA is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria (Non-Negotiable):

• Resistance value: 73.2 Ohms
• Tolerance: ±0.1%
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Package / Case: 0805 (2012 Metric)
• Number of Terminations: 2

Allowable Variations:

• Power rating may be equal to or greater than 0.26W
• Operating temperature range may be narrower than -55°C ~ 175°C, provided it encompasses the application's required operating window
• Automotive AEC-Q200 qualification is maintained across all listed substitutes
• RoHS3 compliance is maintained

The identified substitute parts meet all core criteria while maintaining automotive-grade reliability standards and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB73R2V (Panasonic Electronic Components): This substitute maintains full AEC-Q200 automotive qualification and all core electrical specifications. The power rating of 0.125W is lower than the main part; this substitute is suitable only for applications where the actual power dissipation does not exceed 0.125W. The operating temperature range of -55°C ~ 155°C is narrower than the main part; this substitute is suitable for applications where the maximum operating temperature does not exceed 155°C. This part is recommended for cost-optimized designs where thermal and power constraints permit the lower rating.

1-2176091-1 (TE Connectivity Passive Product): This substitute meets all core electrical specifications and maintains RoHS3 compliance. However, this part does not carry AEC-Q200 automotive qualification. The power rating of 0.25W is lower than the main part; this substitute is suitable only for applications where the actual power dissipation does not exceed 0.25W. The operating temperature range of -55°C ~ 155°C is narrower than the main part; this substitute is suitable for applications where the maximum operating temperature does not exceed 155°C. This part is suitable for non-automotive or non-safety-critical applications only.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB73R2V be used as a direct replacement for TNPW080573R2BEEA in automotive applications?

A: ERA-6AEB73R2V is electrically and mechanically compatible and maintains AEC-Q200 qualification. However, the power rating is 0.125W versus 0.26W on the main part. Substitution is valid only if the actual circuit power dissipation does not exceed 0.125W. Additionally, the maximum operating temperature is 155°C versus 175°C; substitution is valid only if the application does not require operation above 155°C.

Q: What is the difference between the three parts in terms of power handling?

A: TNPW080573R2BEEA is rated for 0.26W, ERA-6AEB73R2V for 0.125W (1/8W), and 1-2176091-1 for 0.25W (1/4W). The power rating indicates the maximum continuous power dissipation the resistor can safely handle. Selection must be based on the actual power dissipation in the circuit.

Q: Is 1-2176091-1 suitable for automotive applications?

A: 1-2176091-1 does not carry AEC-Q200 automotive qualification. This part is not recommended for automotive or safety-critical applications. It is suitable for industrial or consumer-grade applications only.

Q: Are all three parts in the same physical package?

A: All three parts use the 0805 (2012 Metric) package format with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height varies slightly: TNPW080573R2BEEA at 0.022" (0.55mm), ERA-6AEB73R2V at 0.024" (0.60mm), and 1-2176091-1 at 0.026" (0.65mm). These height differences are within typical PCB assembly tolerances and do not affect interchangeability in standard applications.

Q: What does ±0.1% tolerance mean?

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 73.2 Ohm specification. ±0.1% means the actual resistance will be between 73.127 Ohms and 73.273 Ohms. All three substitute parts maintain this same tight tolerance specification.

Q: What is the significance of the ±25ppm/°C temperature coefficient?

A: Temperature coefficient indicates how much the resistance value changes with temperature. ±25ppm/°C means the resistance will change by a maximum of 25 parts per million for each degree Celsius change in temperature. All three parts maintain this specification, ensuring stable performance across the operating temperature range.
