Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FT20L0 is determined by the following critical parameters:

• Resistance value: 20 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum required)
• RoHS compliance: ROHS3 Compliant (required)
• Moisture sensitivity: MSL 1 (required)

The CSRN2010FK20L0 qualifies as a direct substitute based on matching all critical electrical specifications, package dimensions, and compliance certifications. Variations in temperature coefficient and minor dimensional tolerances remain within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both CSR2010FT20L0 and CSRN2010FK20L0 maintain Active product status and satisfy ROHS3 compliance and REACH requirements.

Both parts are certified for identical operating temperature ranges and moisture sensitivity classifications, ensuring functional equivalence in standard PCB assembly and deployment environments.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK20L0 be used as a direct replacement for CSR2010FT20L0?

A: Yes. Both parts share identical resistance (20 mOhms), tolerance (±1%), power rating (1W), package (2010), composition (Thick Film), and current sense functionality. Compliance certifications and operating temperature ranges are equivalent.

Q: What is the difference in temperature coefficient between these parts?

A: CSR2010FT20L0 has a temperature coefficient of ±100ppm/°C, while CSRN2010FK20L0 has ±250ppm/°C. Both remain within acceptable ranges for thick film current sense resistors across the -55°C to 155°C operating window.

Q: Are there dimensional differences between these parts?

A: Minor variations exist within supplier device package tolerances. CSR2010FT20L0 measures 0.197" L x 0.100" W with 0.026" max seated height. CSRN2010FK20L0 measures 0.197" L x 0.097" W with 0.030" max seated height. Both conform to 2010 (5025 Metric) package specifications and are compatible with standard PCB footprints.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, requiring no special moisture control during storage or handling.

Q: Are there supply chain or availability considerations?

A: CSRN2010FK20L0 maintains significantly higher inventory levels, reducing lead time risk for high-volume procurement or time-sensitive applications.
