Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08058K25BETA is determined by the following critical parameters:

• Resistance value: 8.25 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 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 substitute part TNPW08058K25BEEA meets all critical electrical and mechanical parameters. 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 certifications (AEC-Q200, anti-sulfur, moisture resistant), it maintains identical resistance, tolerance, package, composition, and termination specifications, making it functionally compatible for direct substitution in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

The TNPW08058K25BEEA serves as a direct functional substitute for the TNPW08058K25BETA. Both parts are manufactured by Vishay Dale and maintain identical electrical specifications (8.25 kOhms, ±0.1% tolerance, ±25ppm/°C temperature coefficient) and mechanical compatibility (0805 package, 2 terminations).

Selection between these parts should be based on application requirements and compliance mandates:

• The TNPW08058K25BETA is suitable for military applications requiring the specified military-grade designation.
• The TNPW08058K25BEEA is appropriate for automotive applications requiring AEC-Q200 certification and offers ROHS3 compliance, anti-sulfur protection, and extended temperature range to 175°C. This part also provides higher power dissipation capability (0.26W versus 0.125W).

Both parts are active in production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TNPW08058K25BEEA replace TNPW08058K25BETA in all applications?

A: Yes, from an electrical and mechanical standpoint. The substitute maintains identical resistance (8.25 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and package format (0805). However, application-specific requirements such as military qualification, RoHS compliance status, or operating temperature limits must be evaluated. The TNPW08058K25BEEA operates to 175°C versus 125°C for the original part and includes AEC-Q200 automotive certification.

Q: Are there dimensional differences between these parts?

A: No. Both parts use the 0805 (2012 Metric) package with identical physical dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm) and maximum seated height of 0.022" (0.55mm).

Q: What is the significance of the higher power rating on the substitute part?

A: The TNPW08058K25BEEA is rated for 0.26W compared to 0.125W for the TNPW08058K25BETA. This higher power rating provides additional thermal margin in applications with elevated power dissipation, though it does not change the electrical performance or resistance value.

Q: Does RoHS compliance differ between these parts?

A: Yes. The TNPW08058K25BETA is RoHS non-compliant, while the TNPW08058K25BEEA is ROHS3 compliant. Applications subject to RoHS regulations must use the TNPW08058K25BEEA.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both TNPW08058K25BETA and TNPW08058K25BEEA are supplied in Tape & Reel (TR) format suitable for automated assembly processes.
