Substitute Part Grouping Explanation

The CSR2010FKR100 qualifies as a direct substitute for the CSRN2010FTR100 based on the following critical parameters:

• Identical resistance value: 100 mOhms
• Identical tolerance: ±1%
• Identical power rating: 1W
• Identical package: 2010 (5025 Metric)
• Identical composition: Thick Film
• Identical features: Current Sense
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

Both parts are manufactured by Stackpole Electronics Inc and maintain Active product status. The substitute part is suitable for direct replacement in applications where the CSRN2010FTR100 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2010FTR100 and CSR2010FKR100 maintain Active product status with full ROHS3 compliance and identical MSL ratings. The CSR2010FKR100 features an improved temperature coefficient of ±100ppm/°C compared to ±250ppm/°C for the CSRN2010FTR100, providing superior thermal stability in applications subject to temperature fluctuations. Mechanical dimensions are compatible within standard PCB assembly tolerances, with the CSR2010FKR100 offering a slightly reduced seated height. Selection between these parts should be based on inventory availability and application-specific thermal performance requirements.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FKR100 be used as a direct replacement for CSRN2010FTR100?

A: Yes. Both parts share identical electrical specifications (100 mOhms, ±1%, 1W), composition (Thick Film), features (Current Sense), operating temperature range (-55°C ~ 155°C), and package designation (2010 / 5025 Metric). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between these two parts?

A: The primary differences are temperature coefficient (±100ppm/°C for CSR2010FKR100 versus ±250ppm/°C for CSRN2010FTR100) and minor mechanical dimensions. The CSR2010FKR100 width is 0.100" (2.54mm) versus 0.097" (2.45mm), and seated height is 0.026" (0.65mm) versus 0.030" (0.75mm).

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts use identical 2-termination configurations in the 2010 (5025 Metric) package. Mechanical dimension variations are within standard PCB assembly tolerances and do not affect footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CSRN2010FTR100 and CSR2010FKR100 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings.

Q: Which part should be selected for temperature-sensitive applications?

A: The CSR2010FKR100 is suitable for applications requiring superior thermal stability due to its lower temperature coefficient of ±100ppm/°C.
