Substitute Part Grouping Explanation

Substitution of the TNPW080571K5BETA is permissible when the following core parameters remain constant:

• Resistance value: 71.5 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts may differ in power rating (provided it meets or exceeds application requirements), operating temperature range (provided it covers the application's thermal envelope), and compliance certifications. The TNPW080571K5BEEA meets all core substitution criteria while offering enhanced specifications and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The TNPW080571K5BEEA serves as a direct substitute for the TNPW080571K5BETA in applications where the following conditions are met:

• Power dissipation does not exceed 0.26W
• Operating temperature range of -55°C to 175°C is acceptable
• ROHS3 compliance is required or beneficial
• Automotive AEC-Q200 qualification is required or beneficial
• Anti-sulfur and moisture-resistant properties are acceptable

The TNPW080571K5BEEA provides higher power handling capacity (0.26W versus 0.125W), extended upper operating temperature limit (175°C versus 125°C), and ROHS3 compliance. Both parts maintain identical resistance, tolerance, temperature coefficient, and package dimensions, ensuring direct functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TNPW080571K5BEEA replace TNPW080571K5BETA in all applications?

A: Yes, provided the application's power dissipation does not exceed 0.26W and the operating temperature range falls within -55°C to 175°C. The substitute part exceeds the original specifications in both power rating and temperature range.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCBs.

Q: What is the difference in RoHS compliance?

A: TNPW080571K5BETA is RoHS non-compliant, while TNPW080571K5BEEA is ROHS3 compliant. Applications requiring RoHS3 compliance must use the substitute part.
