Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805300KBETA is determined by the following critical parameters:

  • Resistance value: 300 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)
  • Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part TNPW0805300KBEEA meets all critical 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 features (anti-sulfur, automotive AEC-Q200 certification, moisture resistant), the core electrical and mechanical parameters remain equivalent, permitting direct substitution in applications where the main part is specified.

Engineering Selection Recommendations

The TNPW0805300KBEEA substitute part is qualified for direct replacement of the TNPW0805300KBETA based on electrical and mechanical equivalence. The substitute maintains identical resistance, tolerance, temperature coefficient, and package specifications while providing enhanced capabilities.

Selection between the main part and substitute should consider the following factors:

  • RoHS compliance requirements: The substitute (TNPW0805300KBEEA) is ROHS3 compliant, whereas the main part (TNPW0805300KBETA) is RoHS non-compliant. Applications subject to RoHS regulations must use the substitute.
  • Operating temperature requirements: The substitute supports extended temperature operation to 175°C, compared to 125°C for the main part. Applications requiring operation above 125°C must use the substitute.
  • Automotive qualification: The substitute carries AEC-Q200 automotive qualification. Applications requiring automotive-grade components must use the substitute.
  • Power dissipation margin: The substitute offers 0.26W power rating versus 0.125W for the main part, providing additional thermal margin in high-dissipation applications.

Both parts are active in production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805300KBEEA be used as a direct replacement for TNPW0805300KBETA?

A: Yes. Both parts share identical resistance (300 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package (0805), and physical dimensions. The substitute is electrically and mechanically equivalent and suitable for direct substitution in circuit designs.

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

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

Q: Are there any package or footprint differences?

A: No. Both parts use the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and the same number of terminations (2). PCB footprints are interchangeable.

Q: Which part should I select for a new design?

A: Selection depends on application requirements. For RoHS-compliant designs, automotive applications, or designs requiring operation above 125°C, use TNPW0805300KBEEA. For applications with no RoHS requirement and operating temperatures below 125°C, either part is acceptable based on availability and cost considerations.

Q: Is the higher power rating of the substitute a concern?

A: No. A higher power rating does not create compatibility issues. The substitute can be used in any application designed for the main part's 0.125W rating without adverse effects.
