TNPW08051K50BETA Equivalent & Substitute Parts

Part Overview

The TNPW08051K50BETA is a 1.5 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. This military-grade component is designed for precision applications requiring tight tolerance and stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with 1034 units in stock. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08051K50BETA is determined by the following critical parameters:

• Resistance value: 1.5 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The TNPW08051K50BEEA meets all mandatory substitution criteria. This part maintains identical electrical specifications (resistance, tolerance, temperature coefficient) and mechanical compatibility (0805 package, 2-terminal configuration, MSL rating). The substitute part is qualified to higher operating temperature limits (-55°C to 175°C) and includes additional certifications (AEC-Q200, anti-sulfur, moisture resistant) with improved power rating (0.26W versus 0.125W).

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW08051K50BETA and TNPW08051K50BEEA are active production components from Vishay Dale with identical core electrical specifications. Selection between these parts should be based on application requirements and regulatory compliance:

The TNPW08051K50BETA is suitable for applications requiring military-grade thin film resistors with the specified -55°C to 125°C operating range. This part is RoHS non-compliant and REACH-affected.

The TNPW08051K50BEEA provides equivalent electrical performance with extended operating temperature capability (-55°C to 175°C), higher power dissipation capacity (0.26W), and includes AEC-Q200 automotive qualification, anti-sulfur coating, and moisture-resistant construction. This part is ROHS3 compliant and REACH-unaffected, making it suitable for applications with regulatory compliance requirements or automotive environments.

Frequently Asked Questions (FAQ)

Q: Can TNPW08051K50BEEA be used as a direct replacement for TNPW08051K50BETA?

A: Yes. Both parts share identical resistance (1.5 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package (0805), and termination configuration (2-terminal). The substitute part meets or exceeds all electrical and mechanical specifications of the original part.

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

A: The primary differences are power rating (0.26W versus 0.125W), operating temperature range (-55°C to 175°C versus -55°C to 125°C), and compliance certifications. TNPW08051K50BEEA includes AEC-Q200 automotive qualification, anti-sulfur coating, and moisture-resistant construction, and is ROHS3 compliant.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0805 (2012 Metric) with identical length (0.079"), width (0.049"), and maximum seated height (0.022"). They are mechanically interchangeable on PCBs designed for 0805 components.

Q: What does the ±0.1% tolerance specification mean?

A: The tolerance indicates that the actual resistance value will be within ±0.1% of the nominal 1.5 kOhms specification. Both parts maintain this tight tolerance specification.

Q: Does the higher power rating of TNPW08051K50BEEA affect circuit performance?

A: No. The higher power rating (0.26W) indicates the part can safely dissipate more power without exceeding temperature limits. In applications where the original 0.125W rating was adequate, the substitute part will perform identically with additional thermal margin.

Q: Are there packaging format differences?

A: Yes. TNPW08051K50BETA is supplied in Tape & Reel (TR) format. TNPW08051K50BEEA is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for 0805 components and do not affect component performance or PCB assembly compatibility.
