Engineering Selection Recommendations

The TNPW08058K06BEEA serves as a direct substitute for the TNPW08058K06BETA based on identical electrical specifications and package compatibility. Selection between these parts should consider the following factors:

RoHS Compliance: The TNPW08058K06BEEA is ROHS3 compliant, while the TNPW08058K06BETA is RoHS non-compliant. Applications subject to RoHS regulations require the BEEA variant.

Operating Temperature Range: The TNPW08058K06BEEA extends the upper operating limit to 175°C compared to 125°C for the BETA variant. Applications requiring operation at elevated temperatures benefit from this extended range.

Power Dissipation Margin: The TNPW08058K06BEEA provides 0.26W power rating versus 0.125W for the BETA variant. This increased margin accommodates higher power dissipation scenarios within the same package footprint.

Automotive Qualification: The TNPW08058K06BEEA carries AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features. Automotive and harsh environment applications should specify the BEEA variant.

Both parts maintain identical resistance value, tolerance, temperature coefficient, and physical dimensions, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can TNPW08058K06BEEA replace TNPW08058K06BETA in existing designs?

A: Yes. Both parts share identical resistance (8.06 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and 0805 package dimensions. The BEEA variant is electrically and mechanically compatible with designs specified for the BETA variant.

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

A: The primary differences are power rating (0.26W versus 0.125W), operating temperature range (-55°C to 175°C versus -55°C to 125°C), RoHS compliance status (ROHS3 compliant versus non-compliant), and additional features (anti-sulfur, automotive AEC-Q200, moisture resistant in the BEEA variant).

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use identical 0805 (2012 Metric) package dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with 0.022" (0.55mm) maximum seated height. PCB footprints and assembly processes remain unchanged.

Q: Which part should be selected for RoHS-regulated applications?

A: The TNPW08058K06BEEA is ROHS3 compliant and must be specified for applications subject to RoHS directives. The TNPW08058K06BETA is RoHS non-compliant.

Q: Does the higher power rating of TNPW08058K06BEEA affect circuit performance?

A: No. The higher power rating (0.26W versus 0.125W) represents increased thermal capacity and does not alter electrical performance. Resistance value, tolerance, and temperature coefficient remain identical.

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

A: Yes. Both TNPW08058K06BETA and TNPW08058K06BEEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
