TNPW080554R9BEEA Equivalent & Substitute Parts

Part Overview

The TNPW080554R9BEEA is a 54.9 Ohm ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated for 0.26W continuous power dissipation. Manufactured by Vishay Dale, this component is designed for automotive applications with AEC-Q200 qualification, anti-sulfur coating, and moisture resistance. The part is currently active in production with 778 units in stock. Equivalent and substitute parts may be required due to supply chain constraints, design revisions, or specific application requirements where alternative power ratings or manufacturer specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW080554R9BEEA is determined by the following critical parameters:

• Resistance Value: Must be 54.9 Ohms
• Tolerance: Must be ±0.1%
• Package: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The following parameters may vary within acceptable limits for substitution:

• Power Rating: Substitute parts may have equal or higher power ratings (0.125W, 0.25W, or higher)
• Operating Temperature Range: Substitute parts may have equal or narrower upper temperature limits
• Automotive Rating: AEC-Q200 qualification is preferred but not mandatory for all applications
• RoHS Compliance: May differ based on application requirements

Two substitute parts meet the core electrical and mechanical criteria:

1. ERA-6AEB54R9V (Panasonic Electronic Components) – Direct substitute with 0.125W power rating and AEC-Q200 qualification
2. 9-1625868-8 (TE Connectivity Passive Product) – Manufacturer-recommended substitute with 0.25W power rating

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB54R9V (Panasonic Electronic Components) is the primary equivalent substitute. This part maintains full compliance with ROHS3 standards, carries AEC-Q200 automotive qualification, and matches all critical electrical parameters. The 0.125W power rating is lower than the original 0.26W specification; this part is suitable only for applications where the actual power dissipation does not exceed 0.125W. The maximum seated height of 0.024" (0.60mm) is marginally higher than the original 0.022" (0.55mm) and must be evaluated for PCB layout clearance.

9-1625868-8 (TE Connectivity Passive Product) is the manufacturer-recommended alternative. This part provides a 0.25W power rating closer to the original specification and maintains the ±25ppm/°C temperature coefficient. However, this part is RoHS non-compliant and does not carry AEC-Q200 qualification. Selection of this part requires confirmation that the application does not mandate RoHS compliance or automotive-grade certification. The maximum seated height of 0.026" (0.65mm) requires PCB layout verification.

For applications requiring full compliance with automotive standards and environmental regulations, ERA-6AEB54R9V is the recommended choice. For applications with relaxed compliance requirements and higher power dissipation tolerance, 9-1625868-8 provides an alternative with improved power handling.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB54R9V be used as a direct replacement for TNPW080554R9BEEA?

A: ERA-6AEB54R9V is electrically compatible for applications where power dissipation does not exceed 0.125W. The lower power rating is the primary constraint. All other electrical parameters (resistance, tolerance, temperature coefficient) are identical. Physical height difference (0.024" vs 0.022") must be evaluated for PCB clearance.

Q: What is the key difference between the two substitute parts?

A: ERA-6AEB54R9V offers ROHS3 compliance and AEC-Q200 automotive qualification with a 0.125W power rating. 9-1625868-8 provides a higher 0.25W power rating but lacks RoHS compliance and automotive certification. Selection depends on application compliance requirements and actual power dissipation.

Q: Is the 0805 package identical across all three parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated heights differ slightly: TNPW080554R9BEEA at 0.022" (0.55mm), ERA-6AEB54R9V at 0.024" (0.60mm), and 9-1625868-8 at 0.026" (0.65mm). PCB layout must accommodate the maximum height of the selected part.

Q: Can 9-1625868-8 be used in automotive applications?

A: 9-1625868-8 does not carry AEC-Q200 qualification. Use in automotive applications requires confirmation that the specific application does not mandate this certification. RoHS non-compliance must also be evaluated against application requirements.

Q: What is the impact of the ±0.1% tolerance on circuit performance?

A: All three parts maintain ±0.1% tolerance, ensuring identical precision in resistance value. At 54.9 Ohms, the tolerance band is ±0.0549 Ohms, providing consistent circuit performance across all three options.

Q: Are there any height clearance concerns when substituting these parts?

A: Yes. The original part has a maximum seated height of 0.022" (0.55mm). Both substitutes are taller: ERA-6AEB54R9V at 0.024" (0.60mm) and 9-1625868-8 at 0.026" (0.65mm). PCB layout must be verified to ensure adequate clearance above the component.
