Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNPW0805820RBETA is permissible when the following core electrical and mechanical parameters remain constant or are exceeded:

• Resistance value: 820 Ohms
• Tolerance: ±0.1% or tighter
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C or better
• Number of Terminations: 2
• Physical footprint compatibility: 0.079" L x 0.049" W maximum

The substitute part TNPW0805820RBEEA meets all core substitution criteria. It maintains identical resistance, tolerance, package, composition, and temperature coefficient specifications. The substitute provides enhanced power rating (0.26W versus 0.125W), extended operating temperature range (-55°C to 175°C versus -55°C to 125°C), and additional certifications including AEC-Q200 automotive qualification and anti-sulfur/moisture-resistant features.
