Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance value: 7.87 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)

The TNPW08057K87BEEA meets all critical substitution criteria. Variations in power rating, operating temperature range, features, and compliance certifications do not disqualify substitution when the above parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW08057K87BETA and TNPW08057K87BEEA are active production components from Vishay Dale with identical electrical and mechanical specifications for resistance, tolerance, package, and thermal coefficient.

The TNPW08057K87BEEA offers the following advantages:

• Higher power rating (0.26W vs. 0.125W) provides additional thermal margin in the same package footprint
• Extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C) supports high-temperature applications
• ROHS3 compliance and REACH unaffected status for regulatory requirements
• AEC-Q200 automotive qualification for automotive and harsh environment applications
• Significantly higher inventory availability (5404 units vs. 623 units)

Selection between these parts depends on application requirements for power dissipation, maximum operating temperature, regulatory compliance, and supply chain considerations. Both parts are electrically and mechanically interchangeable in standard circuit applications where the specified parameters are not exceeded.

Frequently Asked Questions (FAQ)

Q: Can TNPW08057K87BEEA replace TNPW08057K87BETA in all applications?

A: Yes, provided the application does not require the specific military designation of the TNPW08057K87BETA. The TNPW08057K87BEEA meets all critical electrical parameters (resistance, tolerance, temperature coefficient) and physical specifications (package, dimensions, terminations). The higher power rating and extended temperature range of the BEEA variant are backward compatible with BETA applications.

Q: What is the difference in power rating between these parts?

A: The TNPW08057K87BETA is rated at 0.125W (1/8W), while the TNPW08057K87BEEA is rated at 0.26W. Both parts occupy the same 0805 package footprint. The higher power rating of the BEEA variant indicates improved thermal performance in the same physical size.

Q: Are there package or footprint differences?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.022" / 0.55mm). PCB footprints are identical.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard. The TNPW08057K87BEEA carries this certification, indicating it meets automotive industry reliability and performance requirements. The TNPW08057K87BETA does not carry this designation.

Q: How do RoHS and REACH compliance differ?

A: The TNPW08057K87BETA is RoHS non-compliant and REACH affected. The TNPW08057K87BEEA is ROHS3 compliant and REACH unaffected. For applications requiring regulatory compliance with RoHS3 or REACH standards, the BEEA variant is the appropriate selection.

Q: Is the temperature coefficient identical?

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