Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08052K49BETA is determined by the following critical parameters:

• Resistance value: 2.49 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package / Case: 0805 (2012 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: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)

The TNPW08052K49BEEA meets all substitution criteria. This part maintains identical electrical specifications and mechanical form factor while offering enhanced power rating (0.26W versus 0.125W), extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), and additional certifications including AEC-Q200 automotive qualification and anti-sulfur coating.

Parameter Comparison

Engineering Selection Recommendations

The TNPW08052K49BEEA is a direct substitute for the TNPW08052K49BETA. Both parts are active products from Vishay Dale with identical core electrical and mechanical specifications. Selection between these parts depends on application requirements:

The TNPW08052K49BETA is suitable for applications requiring military-grade specifications within the -55°C ~ 125°C operating range.

The TNPW08052K49BEEA is suitable for applications requiring ROHS3 compliance, AEC-Q200 automotive qualification, extended operating temperature range to 175°C, anti-sulfur coating, moisture resistance, and REACH compliance. The higher power rating (0.26W) provides additional thermal margin in power-dissipation-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can TNPW08052K49BEEA replace TNPW08052K49BETA in all applications?

A: Yes, the TNPW08052K49BEEA is electrically and mechanically compatible with the TNPW08052K49BETA. Both parts share identical resistance, tolerance, temperature coefficient, and 0805 package dimensions. The substitute part offers enhanced specifications including higher power rating and extended temperature range, making it suitable for all applications where the original part is used.

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

A: The primary differences are power rating (0.125W versus 0.26W), operating temperature range (-55°C ~ 125°C versus -55°C ~ 175°C), and compliance certifications. The TNPW08052K49BEEA includes AEC-Q200 automotive qualification, anti-sulfur coating, moisture resistance, ROHS3 compliance, and REACH compliance, while the TNPW08052K49BETA is designated as military-grade.

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 pin-compatible and footprint-compatible.

Q: What is the significance of the higher power rating in TNPW08052K49BEEA?

A: The 0.26W power rating in the substitute part provides greater thermal dissipation capability compared to the 0.125W rating in the original part. This allows the substitute to operate safely in applications with higher power dissipation requirements without exceeding maximum junction temperature limits.

Q: Does the extended temperature range of TNPW08052K49BEEA affect compatibility?

A: No. The extended operating range of -55°C ~ 175°C in the substitute part is a superset of the original part's -55°C ~ 125°C range. The substitute part maintains full compatibility and can be used in all temperature environments where the original part operates.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry qualification standard for passive components. This certification indicates that the TNPW08052K49BEEA meets automotive reliability and quality requirements, making it suitable for automotive and harsh-environment applications.
