Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRF2010JK7L00 is determined by strict equivalence in the following parameters:

• Resistance value: 7 mOhms
• Power rating: 1W
• Package / Case: 2010 (5025 Metric)
• Composition: Metal Foil
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 125°C
• Features: Current Sense, Moisture Resistant
• RoHS and environmental compliance

Tolerance variation is permitted within the substitute group. The CSRF2010JT7L00 provides direct equivalence with identical tolerance (±5%), while the CSRF2010FT7L00 offers improved tolerance (±1%) as an upgrade option. Both substitute parts maintain all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CSRF2010JK7L00 is obsolete; therefore, active substitute parts are required for new designs and ongoing production.

CSRF2010JT7L00 is the direct functional equivalent, maintaining the ±5% tolerance specification of the original part. This substitute is suitable for applications where the original tolerance specification is a design requirement.

CSRF2010FT7L00 is an upgrade option with improved ±1% tolerance while maintaining all other electrical and mechanical characteristics. This part is appropriate for applications requiring tighter tolerance control without design modification.

Both substitute parts are active products with ROHS3 compliance and identical environmental certifications (REACH Unaffected, ECCN EAR99). Packaging is available in Tape & Reel (TR) format for both substitutes.

Frequently Asked Questions (FAQ)

Q: Can CSRF2010JT7L00 replace CSRF2010JK7L00 directly?

A: Yes. The CSRF2010JT7L00 is a direct substitute with identical electrical specifications (7 mOhms, ±5% tolerance, 1W) and mechanical package (2010 / 5025 Metric). Both parts share the same composition, temperature coefficient, and operating range.

Q: What is the difference between CSRF2010JT7L00 and CSRF2010FT7L00?

A: The primary difference is tolerance: CSRF2010JT7L00 has ±5% tolerance, while CSRF2010FT7L00 has ±1% tolerance. All other specifications are identical. The upgrade part provides improved accuracy for precision current sensing applications.

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

A: Yes. All three parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.037" (0.95mm). They are mechanically interchangeable on PCBs designed for this package.

Q: What packaging formats are available for the substitute parts?

A: Both CSRF2010JT7L00 and CSRF2010FT7L00 are available in Tape & Reel (TR) packaging format.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CSRF2010JT7L00 and CSRF2010FT7L00 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.
