Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FT15L0 is determined by the following critical parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Application feature: Current Sense
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant

Two substitute parts meet these core electrical and mechanical requirements: CSR2010FK15L0 and CSRN2010FK15L0. Both maintain identical resistance, tolerance, power rating, and package specifications. Variations in temperature coefficient and physical dimensions are noted in the parameter comparison table below.

Engineering Selection Recommendations

CSR2010FK15L0 is a direct substitute for CSR2010FT15L0. Both parts share identical electrical specifications, temperature coefficient, and physical dimensions. Both are Active status products with ROHS3 compliance and MSL 1 rating.

CSRN2010FK15L0 is functionally compatible with CSR2010FT15L0 for current sense applications. The CSRN series exhibits a higher temperature coefficient (±250ppm/°C versus ±100ppm/°C) and slightly different physical dimensions (width 2.45mm versus 2.54mm, height 0.75mm versus 0.65mm). This part is suitable for applications where the dimensional and temperature coefficient variations are acceptable. CSRN2010FK15L0 is Active status and ROHS3 compliant.

Selection between these substitutes depends on design requirements regarding temperature stability and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FK15L0 replace CSR2010FT15L0 without design changes?

A: Yes. CSR2010FK15L0 is electrically and mechanically identical to CSR2010FT15L0. Both share the same resistance, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications.

Q: What are the key differences between CSR2010FK15L0 and CSRN2010FK15L0?

A: The primary differences are temperature coefficient (±100ppm/°C versus ±250ppm/°C) and physical dimensions. CSRN2010FK15L0 has a width of 2.45mm and height of 0.75mm, compared to 2.54mm width and 0.65mm height for CSR2010FK15L0. Both maintain identical electrical specifications for resistance, tolerance, and power rating.

Q: Is CSRN2010FK15L0 suitable for high-precision temperature-dependent applications?

A: CSRN2010FK15L0 has a temperature coefficient of ±250ppm/°C, which is higher than the ±100ppm/°C of CSR2010FT15L0 and CSR2010FK15L0. Application suitability depends on the specific temperature stability requirements of the circuit design.

Q: Are all three parts ROHS3 compliant?

A: Yes. CSR2010FT15L0, CSR2010FK15L0, and CSRN2010FK15L0 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Will CSRN2010FK15L0 fit in a PCB layout designed for CSR2010FT15L0?

A: CSRN2010FK15L0 has different physical dimensions. The width is 0.09mm narrower (2.45mm versus 2.54mm) and the height is 0.10mm taller (0.75mm versus 0.65mm). PCB layout compatibility must be verified based on specific design constraints and available clearances.
