Substitute Part Grouping Explanation

The RQ73C2A499RBTDF from TE Connectivity Passive Product qualifies as a direct substitute based on the following critical parameters:

Resistance value matches exactly at 499 Ohms with identical ±0.1% tolerance. Composition is thin film, matching the main part specification. Package designation is 0805 (2012 Metric), ensuring mechanical and electrical compatibility. Temperature coefficient is ±10ppm/°C, identical to the main part. Both parts carry AEC-Q200 automotive qualification, anti-sulfur coating, and moisture resistance features. RoHS3 compliance and MSL 1 rating are maintained. Physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) are identical.

The substitute part operates within the allowed parameter range for this resistor category. Power rating of the substitute is 0.2W (1/5W), which is lower than the main part's 0.26W rating. Operating temperature range of the substitute extends to 155°C maximum, compared to 175°C for the main part. These differences represent acceptable trade-offs within the automotive thin film resistor specification envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW0805499RBYEA and RQ73C2A499RBTDF maintain active product status and carry identical AEC-Q200 automotive qualification. ROHS3 compliance is confirmed for both parts. The substitute part RQ73C2A499RBTDF is suitable for applications where the 0.2W power rating is sufficient and the maximum operating temperature requirement does not exceed 155°C. Selection between these parts depends on circuit power dissipation requirements and thermal operating conditions. Both parts are qualified for automotive use and meet moisture and sulfur resistance specifications.
