Both parts are manufactured by Stackpole Electronics Inc and maintain Active product status. Substitution is valid where these electrical and mechanical specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both CSR2010FKR500 and CSRN2010FKR500 are Active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific requirements regarding temperature coefficient stability and physical dimensions. The CSR2010FKR500 features a tighter temperature coefficient of ±100ppm/°C compared to the CSRN2010FKR500 at ±250ppm/°C. The CSRN2010FKR500 has slightly reduced width (2.45mm vs 2.54mm) and increased seated height (0.75mm vs 0.65mm). Both parts maintain identical electrical performance in resistance, tolerance, power rating, and operating temperature range. Component selection should be based on PCB layout constraints and thermal stability requirements specific to the application.
