Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805820KBETA is determined by the following critical parameters:

• Resistance value: 820 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)

Substitute parts must maintain all electrical and mechanical specifications. Power rating may exceed the original specification, and operating temperature range may be extended, provided the minimum operating temperature does not fall below -55°C and the maximum does not fall below 125°C. Composition and thin film construction are mandatory for substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805820KBEEA qualifies as a direct substitute for the TNPW0805820KBETA. Both components are manufactured by Vishay Dale and maintain identical electrical specifications (820 kOhms ±0.1%, ±25ppm/°C) and mechanical compatibility (0805 package, identical dimensions).

The TNPW0805820KBEEA offers enhanced capabilities: increased power dissipation (0.26W versus 0.125W) and extended maximum operating temperature (175°C versus 125°C). The substitute part includes anti-sulfur and moisture-resistant features with AEC-Q200 automotive qualification. The TNPW0805820KBEEA is RoHS3 compliant, whereas the original part is RoHS non-compliant. The substitute part is REACH unaffected, compared to the original part which is REACH affected.

Selection between these parts depends on application requirements for power dissipation, temperature range, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805820KBEEA replace TNPW0805820KBETA in all applications?

A: Yes, provided the application does not require the specific military designation or RoHS non-compliant status of the original part. The substitute maintains all critical electrical parameters and physical compatibility.

Q: What is the significance of the higher power rating in TNPW0805820KBEEA?

A: The 0.26W rating in the substitute part indicates greater power dissipation capability. This does not affect compatibility in applications designed for the 0.125W original part, as the substitute can safely operate at or below the original power specification.

Q: Are there dimensional differences between these parts?

A: No. Both parts use the 0805 (2012 Metric) package 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 extended temperature range in TNPW0805820KBEEA mean for compatibility?

A: The substitute part operates from -55°C to 175°C, compared to the original -55°C to 125°C range. This extended range does not affect compatibility in applications operating within the original temperature window. Applications requiring operation above 125°C can utilize the substitute part.

Q: How do the compliance differences affect part selection?

A: The TNPW0805820KBEEA is RoHS3 compliant and REACH unaffected, whereas the original part is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must use the substitute part. Applications without such regulatory requirements may use either part based on other technical criteria.
