Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805280KBETA is determined by the following critical parameters:

• Resistance Value: Must be 280 kOhms
• Tolerance: Must be ±0.1% or tighter
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Number of Terminations: Must be 2
• Moisture Sensitivity Level: Must be 1 (Unlimited) or equivalent

The substitute part TNPW0805280KBEEA meets all these criteria. While it features a higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), these represent enhanced capabilities that maintain full compatibility with the original specification requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW0805280KBETA and TNPW0805280KBEEA are active production parts with identical electrical specifications (280 kOhms, ±0.1% tolerance, ±25ppm/°C temperature coefficient) and identical mechanical form factors (0805 package, 2.00mm x 1.25mm dimensions).

The TNPW0805280KBEEA offers enhanced compliance status with ROHS3 certification and REACH Unaffected designation, compared to the TNPW0805280KBETA which is RoHS non-compliant and REACH Affected. The substitute part also provides automotive AEC-Q200 qualification, anti-sulfur and moisture-resistant features, higher power dissipation capability (0.26W), and extended operating temperature range (-55°C ~ 175°C).

Selection between these parts depends on regulatory compliance requirements, environmental operating conditions, and application-specific certifications. Both parts maintain identical performance in circuits designed for the original TNPW0805280KBETA specification.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805280KBEEA be used as a direct replacement for TNPW0805280KBETA?

A: Yes. Both parts share identical resistance value (280 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package type (0805), and physical dimensions. The substitute part meets or exceeds all electrical and mechanical requirements of the original part.

Q: What are the differences between these two parts?

A: The primary differences are power rating (0.125W versus 0.26W), operating temperature range (-55°C ~ 125°C versus -55°C ~ 175°C), compliance certifications (RoHS and REACH status), and feature set (military versus automotive AEC-Q200 with anti-sulfur and moisture-resistant properties).

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCBs designed for 0805 resistors.

Q: Does the higher power rating of TNPW0805280KBEEA affect compatibility?

A: No. A higher power rating represents enhanced capability and does not compromise compatibility. The substitute part can safely operate in circuits designed for the lower power rating of the original part.

Q: What is the significance of the RoHS and REACH compliance differences?

A: ROHS3 compliance and REACH Unaffected status indicate the substitute part meets current environmental and hazardous substance regulations. Selection depends on application regulatory requirements and regional compliance mandates.

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

A: Yes. Both TNPW0805280KBETA and TNPW0805280KBEEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
