Substitute Part Grouping Explanation

The CSR2010FKR300 qualifies as a direct substitute for the CSRN2010FTR300 based on the following matching parameters:

• Identical resistance value: 300 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)
• Identical number of terminations: 2

The primary difference between these parts is the temperature coefficient specification, where CSR2010FKR300 provides improved stability at ±100ppm/°C compared to CSRN2010FTR300 at ±250ppm/°C. Both parts are manufactured by Stackpole Electronics Inc and belong to different series within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2010FTR300 and CSR2010FKR300 are Active status components with full RoHS3 compliance and REACH unaffected designation. Selection between these parts should be based on temperature coefficient requirements for the specific application. The CSR2010FKR300 offers superior temperature stability with ±100ppm/°C specification, making it suitable for applications requiring tighter resistance tolerance maintenance across the full operating temperature range. The CSRN2010FTR300 with ±250ppm/°C is appropriate for applications with less stringent temperature coefficient requirements. Both parts maintain identical electrical performance in resistance, tolerance, and power rating, with only minor dimensional variations in width and height that are within standard PCB layout tolerances for 2010 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FKR300 be used as a direct replacement for CSRN2010FTR300?

A: Yes. Both parts share identical electrical specifications for resistance (300 mOhms), tolerance (±1%), power rating (1W), and package (2010). The primary difference is temperature coefficient performance. Dimensional variations are minimal and within standard PCB design tolerances for this package class.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates how much the resistance value changes per degree Celsius within the operating range. CSR2010FKR300 at ±100ppm/°C provides better resistance stability across temperature extremes compared to CSRN2010FTR300 at ±250ppm/°C. Selection depends on application accuracy requirements.

Q: Are there any PCB layout considerations when substituting between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical footprint specifications. Minor dimensional differences (width: 0.097" vs 0.100", height: 0.030" vs 0.026") do not affect standard PCB layout compatibility. Existing footprints accommodate both parts without modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CSRN2010FTR300 and CSR2010FKR300 are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Compliance profiles are identical.

Q: Which part should be selected for current sensing applications?

A: Both parts are designated as current sense resistors with identical specifications. Selection should be based on temperature coefficient requirements and available inventory. The CSR2010FKR300 is preferred for applications requiring tighter temperature stability.
