Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805634KBETA is determined by the following critical parameters:

• Resistance value: 634 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 TNPW0805634KBEEA meets all mandatory substitution criteria. While this substitute offers enhanced power rating (0.26W versus 0.125W), extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), and additional certifications (AEC-Q200, anti-sulfur, moisture resistant), the core electrical and mechanical specifications remain compatible for direct substitution in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW0805634KBETA and TNPW0805634KBEEA are active production components from Vishay Dale with identical core electrical and mechanical specifications. Selection between these parts should be based on application-specific requirements:

The TNPW0805634KBEEA is suitable for applications requiring ROHS3 compliance, automotive qualification (AEC-Q200), extended temperature operation to 175°C, or enhanced environmental protection (anti-sulfur, moisture resistant). The higher power rating (0.26W) provides additional thermal margin in power-dissipation-sensitive circuits.

The TNPW0805634KBETA remains appropriate for applications with military specifications, RoHS non-compliance acceptance, or where the 0.125W power rating and -55°C ~ 125°C operating range are sufficient.

Both parts maintain identical footprint compatibility, resistance accuracy, tolerance, and temperature coefficient, ensuring direct substitution at the PCB assembly level.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805634KBEEA be used as a direct replacement for TNPW0805634KBETA?

A: Yes. Both parts share identical resistance (634 kOhms), tolerance (±0.1%), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and physical dimensions. The substitute offers enhanced specifications (higher power rating, extended temperature range, additional certifications) without compromising compatibility.

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

A: The primary differences are power rating (0.125W versus 0.26W), maximum operating temperature (125°C versus 175°C), RoHS compliance status (non-compliant versus ROHS3 compliant), and certifications (military versus automotive AEC-Q200 with anti-sulfur and moisture-resistant features).

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package 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 TNPW0805634KBEEA affect circuit performance?

A: No. Power rating indicates thermal dissipation capability. A higher-rated component operates at lower junction temperature under the same power dissipation, improving reliability without altering electrical behavior.

Q: What is the significance of the temperature coefficient match?

A: Both parts maintain ±25ppm/°C temperature coefficient, ensuring identical resistance drift characteristics across temperature variations. This is critical for precision analog circuits and filter applications.

Q: Are both parts available in the same packaging format?

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