Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW04023K65BETD is determined by the following critical parameters:

• Resistance value: 3.65 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)
• Physical dimensions and height: Must be identical for PCB compatibility

The TNPW04023K65BEED qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. Differences in power rating (0.13W vs. 0.063W), operating temperature upper limit (175°C vs. 125°C), and compliance certifications represent enhancements rather than deviations from the core specification.

Engineering Selection Recommendations

The TNPW04023K65BEED serves as a direct electrical and mechanical substitute for the TNPW04023K65BETD. Selection between these parts should be based on application requirements and regulatory compliance:

The TNPW04023K65BETD is appropriate for applications requiring military-grade specifications within the -55°C to 125°C operating range where RoHS and REACH compliance are not mandatory constraints.

The TNPW04023K65BEED is suitable for applications requiring ROHS3 compliance, REACH unaffected status, or automotive-grade reliability (AEC-Q200 certification). The extended operating temperature range to 175°C and increased power rating of 0.13W provide additional design margin. This part is recommended for new designs and applications where regulatory compliance is required.

Both parts maintain identical resistance, tolerance, temperature coefficient, and physical dimensions, ensuring direct PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can TNPW04023K65BEED replace TNPW04023K65BETD in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance (3.65 kOhms ±0.1%), tolerance, temperature coefficient (±25ppm/°C), and 0402 package dimensions. The substitute offers enhanced power rating (0.13W vs. 0.063W) and extended temperature range (-55°C to 175°C vs. -55°C to 125°C), making it suitable for direct substitution.

Q: What are the key differences between these parts?

A: The primary differences are compliance certifications and operating specifications. TNPW04023K65BEED is ROHS3 compliant and REACH unaffected, whereas TNPW04023K65BETD is RoHS non-compliant and REACH affected. TNPW04023K65BEED includes AEC-Q200 automotive qualification, anti-sulfur and moisture-resistant features, and operates to 175°C compared to 125°C for the main part.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable on PCBs.

Q: Which part should be selected for new designs?

A: TNPW04023K65BEED is recommended for new designs due to ROHS3 compliance, REACH unaffected status, and AEC-Q200 automotive qualification. The enhanced specifications provide greater design flexibility and regulatory alignment.

Q: Is the higher power rating of TNPW04023K65BEED a concern?

A: No. A higher power rating (0.13W vs. 0.063W) indicates greater thermal capability and does not negatively impact circuit performance. The component will operate safely in applications designed for the lower-rated part.
