Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08055K49BETA is determined by the following criteria:

• Identical resistance value: 5.49 kOhms
• Identical tolerance: ±0.1%
• Identical package / case: 0805 (2012 Metric)
• Identical composition: Thin Film
• Identical temperature coefficient: ±25ppm/°C
• Identical number of terminations: 2
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Identical height - seated (max): 0.022" (0.55mm)

The substitute part TNPW08055K49BEEA meets all these criteria. Variations in power rating, operating temperature range, and product certifications do not affect mechanical or electrical substitutability within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The TNPW08055K49BEEA serves as a direct substitute for the TNPW08055K49BETA with the following considerations based on provided specifications:

The substitute part offers higher power dissipation capability (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), providing enhanced thermal margin in applications requiring sustained power delivery or elevated temperature operation.

The TNPW08055K49BEEA carries AEC-Q200 automotive qualification and incorporates anti-sulfur and moisture-resistant features, making it suitable for automotive and harsh environment applications. This part achieves ROHS3 compliance and REACH unaffected status, whereas the original part is RoHS non-compliant and REACH affected.

Both parts maintain identical electrical characteristics: 5.49 kOhms resistance, ±0.1% tolerance, ±25ppm/°C temperature coefficient, and 0805 package footprint with matching physical dimensions and termination count.

Frequently Asked Questions (FAQ)

Q: Can TNPW08055K49BEEA be used as a direct replacement for TNPW08055K49BETA in existing designs?

A: Yes. Both parts share identical resistance value (5.49 kOhms), tolerance (±0.1%), package (0805), physical dimensions, and temperature coefficient (±25ppm/°C). The substitute part is mechanically and electrically compatible for PCB assembly and circuit operation.

Q: What are the 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), product certifications (AEC-Q200 for the substitute), and compliance status (ROHS3 compliant and REACH unaffected for the substitute versus non-compliant for the original).

Q: Does the higher power rating of TNPW08055K49BEEA affect circuit performance?

A: No. Higher power rating does not alter electrical performance. It provides additional thermal headroom and allows operation in higher dissipation scenarios without degradation.

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

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) format with identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm).

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The TNPW08055K49BEEA is suitable for automotive applications, high-temperature environments, and designs requiring RoHS3 compliance. The TNPW08055K49BETA remains appropriate for applications within its specified operating range where compliance status is not a constraint.
