Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08054K30BETA is determined by the following criteria:

• Resistance value: 4.3 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Composition: Thin Film (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The TNPW08054K30BEEA qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The substitute part maintains identical resistance, tolerance, composition, package format, temperature coefficient, and termination specifications. Differences in power rating (0.26W vs. 0.125W) and operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C) represent enhanced capabilities that do not prevent substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW08054K30BEEA is a direct electrical and mechanical substitute for the TNPW08054K30BETA. Both parts are active products from Vishay Dale with identical core specifications: 4.3 kOhms resistance, ±0.1% tolerance, thin film composition, 0805 package, and ±25ppm/°C temperature coefficient.

The substitute part offers ROHS3 compliance and REACH unaffected status, whereas the original part is RoHS non-compliant and REACH affected. The TNPW08054K30BEEA includes automotive AEC-Q200 certification, anti-sulfur and moisture-resistant features, higher power rating (0.26W vs. 0.125W), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C). These enhancements provide greater design margin and regulatory compliance without altering the core electrical performance required for applications specified for the TNPW08054K30BETA.

Frequently Asked Questions (FAQ)

Q: Can TNPW08054K30BEEA replace TNPW08054K30BETA in existing designs?

A: Yes. The substitute part maintains identical resistance value (4.3 kOhms), tolerance (±0.1%), composition (thin film), package format (0805), temperature coefficient (±25ppm/°C), and physical dimensions. Electrical performance in the specified operating range is equivalent.

Q: What are the differences between these two parts?

A: The primary differences are power rating (0.26W vs. 0.125W), operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C), regulatory compliance (ROHS3 vs. RoHS non-compliant), and certifications (AEC-Q200 automotive qualification and anti-sulfur/moisture-resistant features in the substitute).

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package format with identical length (0.079"), width (0.049"), and maximum seated height (0.022"). PCB footprints are interchangeable.

Q: Does the higher power rating of TNPW08054K30BEEA affect compatibility?

A: No. Higher power rating indicates enhanced thermal capability and does not create incompatibility. The substitute part will operate within the same electrical parameters as the original part in applications designed for 0.125W rating.

Q: What is the significance of AEC-Q200 certification on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The TNPW08054K30BEEA meets automotive reliability and performance requirements, providing additional assurance for applications requiring automotive-grade components.
