Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FKR220 is determined by strict equivalence across the following critical parameters:

• Resistance value: 220 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS3 compliance

The RCWE2010R220FKEA from Vishay Dale meets all these core electrical and mechanical requirements. Additional features such as AEC-Q200 automotive qualification and moisture-resistant construction in the substitute part represent enhanced capabilities that do not compromise compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR2010FKR220 and RCWE2010R220FKEA are Active status components with full RoHS3 compliance and unlimited moisture sensitivity ratings. The RCWE2010R220FKEA provides additional AEC-Q200 automotive qualification and moisture-resistant construction, making it suitable for applications requiring automotive-grade reliability. Selection between these parts should be based on application requirements: the CSR2010FKR220 for general industrial current sensing applications, and the RCWE2010R220FKEA for automotive or moisture-critical environments where enhanced qualification is beneficial.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R220FKEA replace CSR2010FKR220 in existing designs?

A: Yes. Both parts share identical electrical specifications (220 mOhms ±1%, 1W, ±100ppm/°C) and mechanical package (2010/5025 Metric). The substitute part has minor dimensional variations (width 2.50mm vs 2.54mm, height 0.70mm vs 0.65mm) that remain within standard PCB footprint tolerances for this package class.

Q: What is the significance of AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. This qualification indicates the RCWE2010R220FKEA meets automotive reliability and testing requirements. It is not required for non-automotive applications but provides additional assurance for automotive or high-reliability environments.

Q: Are there any thermal performance differences between these parts?

A: Both parts have identical temperature coefficients (±100ppm/°C) and operating ranges (-55°C ~ 155°C). Thermal performance in current sensing applications is equivalent.

Q: Do package dimensions require PCB layout changes?

A: Minor dimensional differences exist (width and height variations under 0.1mm). Standard 2010 package footprints accommodate both parts without layout modification.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both CSR2010FKR220 and RCWE2010R220FKEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly.
