Key Parameters

Substitute Part Grouping Explanation

Substitution for the TNPW0805750KBETA is determined by strict equivalence in the following parameters:

• Resistance value: 750 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2

The substitute part TNPW0805750KBEEA maintains all critical electrical and mechanical parameters. Differences 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 TNPW0805750KBEEA serves as a direct electrical and mechanical substitute for the TNPW0805750KBETA. Both parts share identical resistance, tolerance, temperature coefficient, and package specifications. The substitute part offers enhanced capabilities including higher power dissipation (0.26W vs. 0.125W), extended operating temperature range (-55°C to 175°C vs. -55°C to 125°C), and additional environmental protection features (Anti-Sulfur, Automotive AEC-Q200 certification, Moisture Resistant).

The TNPW0805750KBEEA achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Selection between these parts depends on application requirements for regulatory compliance, thermal performance margin, and environmental durability. Both parts maintain identical footprint and electrical characteristics for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805750KBEEA replace TNPW0805750KBETA in existing designs?

A: Yes. Both parts maintain identical resistance (750 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and 0805 package dimensions. Electrical performance and PCB footprint compatibility are preserved.

Q: What are the key differences between these parts?

A: The substitute part offers higher power rating (0.26W vs. 0.125W), extended operating temperature range (175°C vs. 125°C), Anti-Sulfur and Automotive AEC-Q200 features, and ROHS3 compliance. The original part carries military designation.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 1.25mm W (2.00mm x 1.25mm) with 0.022" (0.55mm) maximum seated height in 0805 (2012 Metric) package format.

Q: Does the higher power rating of the substitute affect circuit operation?

A: No. Higher power rating indicates greater thermal capability and does not alter electrical behavior. The part operates within the same voltage and current parameters as the original.

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

A: AEC-Q200 certification indicates automotive-grade reliability qualification. This certification is provided on the substitute part but not on the original military-grade part.

Q: Are both parts suitable for high-temperature applications?

A: The original part operates to 125°C. The substitute part extends to 175°C, providing additional thermal margin for elevated-temperature environments.
