Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08052K40BETA is determined by the following critical parameters:

• Resistance value: 2.4 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, Height 0.022" max (exact match required)

The substitute part TNPW08052K40BEEA meets all mandatory electrical and mechanical parameters. Differences in power rating, operating temperature range, and product certifications do not affect functional substitutability in applications where the original part specifications are met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW08052K40BETA and TNPW08052K40BEEA are active production components from Vishay Dale with identical electrical specifications and package geometry. Selection between these parts is based on application compliance and environmental requirements:

The TNPW08052K40BETA is suitable for military applications requiring the specified thin film resistor characteristics within the -55°C to 125°C operating range.

The TNPW08052K40BEEA provides ROHS3 compliance and REACH unaffected status, making it appropriate for applications subject to environmental regulations. The extended operating temperature range (-55°C to 175°C) and higher power rating (0.26W versus 0.125W) provide additional design margin. AEC-Q200 automotive qualification indicates suitability for automotive applications.

Both parts are electrically and mechanically interchangeable in 0805 package footprints where the specified resistance, tolerance, and thin film composition are required.

Frequently Asked Questions (FAQ)

Q: Can TNPW08052K40BEEA replace TNPW08052K40BETA in all applications?

A: Yes, from an electrical and mechanical standpoint. The substitute part meets or exceeds all critical parameters: identical resistance (2.4 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package (0805), and physical dimensions. The higher power rating (0.26W versus 0.125W) and extended temperature range (-55°C to 175°C) do not create incompatibility. Application-specific compliance requirements (RoHS, REACH, AEC-Q200) must be evaluated separately.

Q: Are there physical footprint differences between these parts?

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 of 0.022" (0.55mm). PCB layout and assembly processes require no modification.

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

A: TNPW08052K40BETA is rated at 0.125W (1/8W), while TNPW08052K40BEEA is rated at 0.26W. The higher power rating of the substitute part provides additional thermal margin and does not affect electrical performance in circuits designed for the original part's specifications.

Q: Which part should be selected for automotive applications?

A: TNPW08052K40BEEA carries AEC-Q200 automotive qualification and is the appropriate choice for automotive applications. It also provides ROHS3 compliance and REACH unaffected status.

Q: Are there temperature range considerations for substitution?

A: TNPW08052K40BETA operates from -55°C to 125°C, while TNPW08052K40BEEA operates from -55°C to 175°C. The substitute part's extended upper temperature limit provides additional design margin but does not restrict its use in applications limited to the original part's temperature range.
