CSR1206FKR220 Equivalent & Substitute Parts

Part Overview

The CSR1206FKR220 is a 220 mOhms ±1% thick film chip resistor in 1206 (3216 Metric) package rated for 0.5W power dissipation. Manufactured by Stackpole Electronics Inc., this current sense resistor is designed for precision low-resistance applications requiring tight tolerance and stable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings align with the original component's functional requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FKR220 is determined by strict alignment of the following parameters:

  • Electrical Specifications: Resistance value (220 mOhms), tolerance (±1%), power rating (0.5W), and temperature coefficient (±100ppm/°C) must match exactly
  • Package Compatibility: 1206 (3216 Metric) package form factor with equivalent termination count (2 terminations)
  • Environmental Compliance: RoHS3 compliance, MSL rating of 1 or better, and operating temperature range of -55°C ~ 155°C or wider
  • Composition & Function: Thick film construction with current sense capability

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the original component.

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS3 compliance with identical core electrical and thermal specifications. Selection between these substitutes should be based on:

CSR1206FKR220 (Stackpole Electronics Inc.): Standard current sense resistor for general industrial applications. Suitable for designs where component availability and cost are primary considerations.

CRM1206-FX-R220ELF (Bourns Inc.): Functionally equivalent with identical electrical performance. Available in Cut Tape and Digi-Reel packaging options, offering flexibility in procurement quantities.

RCWE1206R220FKEA (Vishay Dale): Includes Automotive AEC-Q200 qualification and moisture-resistant construction in addition to base specifications. Appropriate for automotive applications or environments requiring enhanced reliability certifications.

Frequently Asked Questions (FAQ)

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All three parts share identical electrical specifications (220 mOhms ±1%, 0.5W, ±100ppm/°C), package form factor (1206), and environmental ratings. They are mechanically and electrically interchangeable.

Q: What is the significance of the AEC-Q200 rating on the Vishay part? A: AEC-Q200 is an automotive qualification standard. The RCWE1206R220FKEA meets this specification, making it suitable for automotive applications where such certification is required. The other parts do not carry this designation.

Q: Are there packaging differences that affect assembly? A: The CSR1206FKR220 and RCWE1206R220FKEA are supplied in Tape & Reel format. The CRM1206-FX-R220ELF is available in Cut Tape and Digi-Reel options. All are compatible with standard pick-and-place assembly equipment for 1206 packages.

Q: Do all parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity). They share identical ECCN (EAR99) and HTSUS classifications.

Q: What determines if a part can substitute for the CSR1206FKR220? A: Substitution requires matching resistance value (220 mOhms), tolerance (±1%), power rating (0.5W), package (1206), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance certifications (RoHS3, MSL 1). All identified parts meet these criteria.
