Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FTR300 is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 300 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Features: Current Sense
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Allowable Variations:

• Temperature coefficient may vary within acceptable engineering margins
• Physical dimensions may have minor tolerances within package specification
• Height seated maximum may vary within package class limits

The identified substitutes CSR2010FKR300 and CSRN2010FKR300 maintain all primary matching parameters while operating within the defined package and performance envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CSR2010FTR300, CSR2010FKR300, and CSRN2010FKR300—are Active status components manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance and MSL 1 rating.

CSR2010FTR300 and CSR2010FKR300 are direct equivalents with identical electrical and mechanical specifications, including temperature coefficient of ±100ppm/°C and physical dimensions.

CSRN2010FKR300 differs in temperature coefficient (±250ppm/°C) and physical dimensions (width 0.097" vs 0.100", height 0.030" vs 0.026"). These variations remain within the 2010 package class specification. Selection between CSR and CSRN series depends on application temperature stability requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FKR300 directly replace CSR2010FTR300?

A: Yes. Both parts share identical resistance (300 mOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), package (2010), and physical dimensions. They are functionally equivalent.

Q: What is the key difference between CSR2010FTR300 and CSRN2010FKR300?

A: The CSRN2010FKR300 has a higher temperature coefficient (±250ppm/°C vs ±100ppm/°C) and slightly different physical dimensions (width 0.097" vs 0.100", height 0.030" vs 0.026"). Both remain within 2010 package specifications. Selection depends on temperature stability and PCB space requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. CSR2010FTR300, CSR2010FKR300, and CSRN2010FKR300 are all ROHS3 compliant with MSL 1 rating.

Q: Can CSRN2010FKR300 be used in high-precision temperature applications?

A: The CSRN2010FKR300 has a temperature coefficient of ±250ppm/°C, which is higher than the CSR series (±100ppm/°C). Application suitability depends on specific temperature stability requirements.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in Tape & Reel (TR) packaging. Physical dimensions vary slightly: CSR2010FTR300 and CSR2010FKR300 are 0.197" L x 0.100" W x 0.026" H, while CSRN2010FKR300 is 0.197" L x 0.097" W x 0.030" H. Verify PCB layout compatibility before selection.
