Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW080591K0BETA is determined by the following critical parameters:

• Resistance value: 91 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package type: 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)
• Physical dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)

The TNPW080591K0BEEA meets all substitution criteria. While this part 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 do not compromise compatibility. The higher power rating and extended temperature range provide additional design margin without affecting electrical performance in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW080591K0BETA and TNPW080591K0BEEA are active products from Vishay Dale with identical electrical specifications for resistance, tolerance, and temperature coefficient. Selection between these parts should be based on the following criteria:

The TNPW080591K0BEEA offers ROHS3 compliance and automotive AEC-Q200 qualification with anti-sulfur and moisture-resistant features. This part is suitable for applications requiring regulatory compliance or automotive-grade reliability. The extended operating temperature range to 175°C provides additional thermal margin for high-temperature environments.

The TNPW080591K0BETA is specified for military applications and is available in Tape & Reel packaging. This part is appropriate for applications with military specifications or where the original part number must be maintained.

Both parts are mechanically and electrically interchangeable within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can TNPW080591K0BEEA replace TNPW080591K0BETA in existing designs?

A: Yes. Both parts share identical resistance (91 kOhms), tolerance (±0.1%), composition (thin film), package (0805), temperature coefficient (±25ppm/°C), and physical dimensions. The TNPW080591K0BEEA features a higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), which represent enhanced capabilities that do not affect compatibility.

Q: What is the difference in packaging between these parts?

A: The TNPW080591K0BETA is supplied in Tape & Reel (TR) packaging, while the TNPW080591K0BEEA is supplied in Cut Tape (CT) packaging. Both packaging formats are standard for 0805 chip resistors and do not affect component performance or PCB assembly compatibility.

Q: Are there compliance differences between these parts?

A: The TNPW080591K0BETA is RoHS non-compliant, while the TNPW080591K0BEEA is ROHS3 compliant. The TNPW080591K0BEEA also carries AEC-Q200 automotive qualification and includes anti-sulfur and moisture-resistant features. Applications requiring regulatory compliance should specify the TNPW080591K0BEEA.

Q: Do these parts have the same operating temperature range?

A: No. The TNPW080591K0BETA operates from -55°C to 125°C, while the TNPW080591K0BEEA operates from -55°C to 175°C. For applications requiring operation above 125°C, the TNPW080591K0BEEA is required.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with identical dimensions: 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 components.
