Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08051K00BETA is determined by the following critical parameters:

Resistance value and tolerance must remain 1 kOhms ±0.1%. Package format must be 0805 (2012 Metric) with identical physical dimensions (0.079" L x 0.049" W). Composition must be thin film. Temperature coefficient must be ±25ppm/°C. Moisture Sensitivity Level must be 1 (Unlimited). Number of terminations must be 2.

The substitute part TNPW08051K00BEEA meets all these core requirements. While this substitute offers enhanced power rating (0.26W versus 0.125W), extended operating temperature range (-55°C to 175°C versus -55°C to 125°C), and additional features (anti-sulfur, automotive AEC-Q200, moisture resistant), these represent improvements that do not compromise compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW08051K00BEEA serves as a direct substitute for the TNPW08051K00BETA based on matching core electrical and mechanical specifications. The substitute part is ROHS3 Compliant and REACH Unaffected, compared to the original part which is RoHS non-compliant and REACH Affected. The substitute carries AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features, making it suitable for applications requiring enhanced environmental performance. Both parts share identical package geometry, termination count, and moisture sensitivity classification, ensuring PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can TNPW08051K00BEEA replace TNPW08051K00BETA in existing designs?

A: Yes. Both parts maintain identical resistance (1 kOhms ±0.1%), package format (0805), physical dimensions, and termination configuration. The substitute offers higher power dissipation capability and extended temperature range, which do not create incompatibility with circuits designed for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are power rating (0.26W versus 0.125W), maximum operating temperature (175°C versus 125°C), and compliance certifications. TNPW08051K00BEEA includes AEC-Q200 automotive qualification, anti-sulfur coating, and moisture-resistant features. TNPW08051K00BEEA is ROHS3 Compliant and REACH Unaffected, while TNPW08051K00BETA is RoHS non-compliant and REACH Affected.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with 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 designed for 0805 resistors.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±25ppm/°C, ensuring equivalent frequency stability and thermal performance characteristics.
