Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F680CS is determined by strict alignment of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 68 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)

Mechanical Parameters (Must Match Exactly):

• Package type: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated (max): 0.010" (0.26mm)
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

The CRCW020168R0FKED manufactured by Vishay Dale meets all mandatory electrical and mechanical criteria for direct substitution. Both components share identical resistance, tolerance, power rating, and package specifications. Compliance certifications are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

The CRCW020168R0FKED is a direct equivalent substitute for the RC0603F680CS based on the following engineering criteria:

Electrical Equivalence: Both components deliver identical resistance (68 Ohms), tolerance (±1%), and power dissipation (0.05W). These specifications ensure functional interchangeability in circuit applications.

Mechanical Compatibility: Identical package dimensions (0201 / 0603 Metric) and physical footprint enable direct PCB layout compatibility without design modification.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, satisfying regulatory and environmental requirements.

Performance Advantages: The Vishay Dale substitute exhibits superior temperature stability (±100ppm/°C versus ±250ppm/°C) and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C), providing enhanced performance margins in demanding thermal environments.

Product Status: Both components maintain Active product status, ensuring continued availability and manufacturing support.

Selection between these parts may be based on supplier availability, packaging format preference (Cut Tape versus Tape & Reel), or inventory requirements, as all technical and compliance parameters are equivalent or superior in the substitute part.

Frequently Asked Questions (FAQ)

Q: Can CRCW020168R0FKED replace RC0603F680CS in existing designs without PCB modification?

A: Yes. Both components share identical package dimensions (0201 / 0603 Metric), physical footprint, and electrical specifications. Direct PCB substitution is possible without layout changes.

Q: Are there differences in temperature performance between these parts?

A: The Vishay Dale CRCW020168R0FKED operates across a wider temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and exhibits superior temperature coefficient stability (±100ppm/°C versus ±250ppm/°C). These represent performance enhancements rather than limitations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC0603F680CS and CRCW020168R0FKED are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging provides individual component strips suitable for manual assembly or small-volume applications. Tape & Reel packaging supplies components on continuous reels for automated pick-and-place assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are the electrical specifications truly identical?

A: Yes. Resistance value (68 Ohms), tolerance (±1%), and power rating (0.05W / 1/20W) are identical across both parts. Substitution is electrically transparent.

Q: Can I use CRCW020168R0FKED in applications originally specified for RC0603F680CS?

A: Yes. Identical electrical and mechanical specifications, combined with equivalent or superior environmental performance, ensure functional compatibility in all applications where the original part was specified.
