Substitute Part Grouping Explanation

Substitute parts for the CSRF2010JT3L00 are qualified based on the following criteria:

Allowed Substitution Parameters:

• Identical resistance value: 3 mOhms
• Identical package: 2010 (5025 Metric)
• Identical termination count: 2
• Identical features: Current Sense, Moisture Resistant
• Identical RoHS compliance: ROHS3 Compliant
• Identical REACH status: REACH Unaffected

Acceptable Variations:

• Tolerance may be improved (tighter than ±5%)
• Power rating may be equal or higher
• Composition may differ (Metal Foil or Metal Element)
• Operating temperature range may be extended
• Temperature coefficient may be specified

The two qualified substitutes meet all mandatory criteria while offering enhanced specifications in tolerance and/or power rating.

Parameter Comparison

Engineering Selection Recommendations

CSRF2010FT3L00 provides a direct upgrade path with improved tolerance (±1% versus ±5%) while maintaining identical power rating, composition, and operating temperature range. This part is suitable for applications requiring tighter resistance accuracy without thermal or power constraints.

CSNL2010FT3L00 offers enhanced specifications across multiple parameters: ±1% tolerance, 1.5W power rating (50% increase), and extended operating temperature range to 170°C. The metal element composition differs from the original metal foil construction. This part is suitable for applications with higher power dissipation requirements or extended temperature operation.

Both substitutes maintain full compliance with ROHS3 and REACH requirements, identical package dimensions, and current sense functionality. Selection depends on specific application requirements for tolerance, power handling, and operating temperature.

Frequently Asked Questions (FAQ)

Q: Can CSRF2010FT3L00 be used as a direct replacement for CSRF2010JT3L00?

A: Yes. Both parts share identical resistance, power rating, package, composition, and operating temperature range. The CSRF2010FT3L00 provides improved tolerance specification (±1% versus ±5%), making it suitable for applications where the original tolerance is acceptable or where tighter tolerance is beneficial.

Q: What is the primary difference between CSRF2010FT3L00 and CSNL2010FT3L00?

A: The CSNL2010FT3L00 offers higher power rating (1.5W versus 1W), extended operating temperature range (-55°C to 170°C versus -55°C to 125°C), and uses metal element composition instead of metal foil. Both maintain ±1% tolerance and identical package specifications.

Q: Are the physical dimensions identical across all three parts?

A: The CSRF2010JT3L00 and CSRF2010FT3L00 share identical dimensions (0.197" L x 0.098" W, 0.037" max height). The CSNL2010FT3L00 has slightly larger dimensions (0.200" L x 0.100" W, 0.041" max height) but uses the same 2010 (5025 Metric) package classification and maintains PCB footprint compatibility.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0030) codes.

Q: Which substitute should be selected for high-temperature applications?

A: The CSNL2010FT3L00 is specified for operation up to 170°C, compared to 125°C for both CSRF variants. This part is required for applications exceeding 125°C operating temperature.
