Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805150KBETA is determined by the following critical parameters:

• Resistance value: 150 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package type: 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 TNPW0805150KBEEA qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. Variations in power rating (0.26W vs. 0.125W), operating temperature upper limit (175°C vs. 125°C), and additional features (anti-sulfur, automotive AEC-Q200, moisture resistant) represent enhancements that do not compromise compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805150KBEEA serves as a direct functional equivalent to the TNPW0805150KBETA. Selection between these parts should be based on application requirements and compliance mandates:

For applications requiring RoHS3 compliance, the TNPW0805150KBEEA is the appropriate choice, as the original part is RoHS non-compliant. The substitute part's higher power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C to 175°C vs. -55°C to 125°C) provide additional thermal margin without affecting electrical performance in circuits designed for the original specification.

For automotive applications or environments requiring anti-sulfur and moisture-resistant properties, the TNPW0805150KBEEA with AEC-Q200 qualification is the specified alternative. The TNPW0805150KBETA remains suitable for military applications where the original specification is explicitly required.

Both parts maintain identical resistance, tolerance, temperature coefficient, and physical dimensions, ensuring direct PCB compatibility and circuit performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805150KBEEA be used as a direct replacement for TNPW0805150KBETA on existing PCBs?

A: Yes. Both parts share identical package dimensions (0805), footprint, resistance value (150 kOhms), tolerance (±0.1%), and temperature coefficient (±25ppm/°C). No PCB layout modifications are required.

Q: What is the significance of the higher power rating on the TNPW0805150KBEEA?

A: The TNPW0805150KBEEA is rated for 0.26W compared to the TNPW0805150KBETA's 0.125W. This higher rating provides additional thermal headroom in power-dissipation-limited applications but does not alter electrical behavior in circuits designed for the original 0.125W specification.

Q: Does the extended operating temperature range of TNPW0805150KBEEA affect compatibility?

A: No. The extended range (-55°C to 175°C vs. -55°C to 125°C) is a superset of the original specification. Applications operating within the original temperature range remain fully compatible.

Q: What compliance differences exist between these parts?

A: TNPW0805150KBETA is RoHS non-compliant, while TNPW0805150KBEEA is ROHS3 compliant. TNPW0805150KBEEA also carries AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features. Select based on your application's regulatory and environmental requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable.

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

A: The ±0.1% tolerance indicates that the actual resistance value will fall within 149.85 kOhms to 150.15 kOhms. This tight tolerance is maintained on both the original and substitute part, ensuring consistent circuit performance.
