CSR2010FK10L0 Equivalent & Substitute Parts

Part Overview

The CSR2010FK10L0 is a 10 mOhms ±1% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This current sense thick film resistor is designed for precision low-resistance applications requiring high power dissipation in compact form factors. The part is Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FK10L0 is determined by the following critical parameters:

• Resistance value: 10 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 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 (exact match required)
• RoHS3 compliance (required for regulatory compatibility)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The substitute parts CSRN2010FK10L0 and CSRN2010FT10L0 meet all critical electrical and mechanical parameters. Both are manufactured by Stackpole Electronics Inc in the same CSRN series, maintain identical resistance, tolerance, power rating, package configuration, and environmental specifications. The primary difference is the temperature coefficient specification, which varies between the main part and substitutes but does not affect substitution eligibility within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CSR2010FK10L0, CSRN2010FK10L0, and CSRN2010FT10L0—are Active status components with full RoHS3 compliance and REACH Unaffected certification, making them suitable for regulated applications. Selection between these parts should be based on availability and lead time requirements, as all meet the specified electrical and mechanical criteria for 10 mOhms ±1% 1W current sense resistor applications in 2010 package format.

The CSRN2010FT10L0 offers the highest inventory availability (12,084 pcs) among the substitute options, followed by CSRN2010FK10L0 (6,175 pcs), while the original CSR2010FK10L0 maintains 699 pcs in stock. Physical dimensions vary slightly between the original part and substitutes, with the original CSR2010FK10L0 measuring 0.100" width and 0.026" maximum seated height, compared to 0.097" width and 0.030" maximum seated height for both CSRN variants. These dimensional differences must be evaluated against specific PCB layout and assembly constraints.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK10L0 and CSRN2010FT10L0 be used interchangeably with CSR2010FK10L0?

A: Both CSRN variants meet the core electrical specifications (10 mOhms ±1%, 1W, thick film, current sense, -55°C to 155°C operating range) and package classification (2010/5025 Metric). However, physical dimensions differ slightly. The CSRN parts are 0.097" wide and 0.030" maximum height, while the CSR2010FK10L0 is 0.100" wide and 0.026" maximum height. PCB layout compatibility must be confirmed before substitution.

Q: What is the significance of the temperature coefficient difference?

A: The CSR2010FK10L0 specifies ±100ppm/°C, while both CSRN substitutes specify ±250ppm/°C. This parameter was provided in the input data and represents a specification difference between the parts. Application-specific thermal stability requirements should be evaluated against these values.

Q: Are all three parts RoHS3 compliant?

A: Yes. CSR2010FK10L0, CSRN2010FK10L0, and CSRN2010FT10L0 are all ROHS3 Compliant with REACH Unaffected status, suitable for applications requiring regulatory compliance.

Q: What is the moisture sensitivity rating?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Which substitute part has the best availability?

A: CSRN2010FT10L0 has the highest inventory at 12,084 pcs, followed by CSRN2010FK10L0 at 6,175 pcs. Both are available in Tape & Reel packaging.
