Substitute Part Grouping Explanation

Substitution of the RC0603F5111CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.11 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package / Case: 0201 (0603 Metric)
• Composition: Thick Film
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• RoHS3 compliance
• MSL 1 rating

The substitute part CRCW02015K11FKED from Vishay Dale meets all mandatory parameters. Both components share identical resistance, tolerance, power rating, package specification, and physical dimensions. Both are RoHS3 compliant with MSL 1 moisture sensitivity rating, ensuring direct functional and mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F5111CS and CRCW02015K11FKED are Active product status components with full RoHS3 compliance and MSL 1 ratings. The components are electrically and mechanically equivalent for standard circuit applications requiring 5.11 kOhms ±1% resistance at 0.05W power dissipation in 0201 package form factor.

The CRCW02015K11FKED exhibits a lower temperature coefficient (±100ppm/°C versus ±250ppm/°C) and an extended upper operating temperature limit (155°C versus 125°C). These characteristics provide enhanced performance stability in temperature-sensitive applications and environments with elevated thermal conditions. Selection between these parts should be based on application-specific temperature performance requirements and supply availability.

Both components satisfy identical regulatory and compliance requirements, including RoHS3, REACH Unaffected status, and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can CRCW02015K11FKED be used as a direct replacement for RC0603F5111CS?

A: Yes. Both components share identical resistance value (5.11 kOhms), tolerance (±1%), power rating (0.05W), package specification (0201), physical dimensions (0.024" L x 0.012" W), and compliance certifications (RoHS3, MSL 1). Direct substitution is supported for circuit applications within the RC0603F5111CS operating temperature range of -55°C to 125°C.

Q: What are the differences between these two parts?

A: The primary differences are temperature coefficient and maximum operating temperature. The CRCW02015K11FKED has a temperature coefficient of ±100ppm/°C compared to ±250ppm/°C for the RC0603F5111CS, and supports operation up to 155°C versus 125°C. These differences provide improved thermal stability and extended temperature range capability with the Vishay Dale component.

Q: Are both parts available in the same packaging format?

A: Yes. Both RC0603F5111CS and CRCW02015K11FKED are supplied in Tape & Reel (TR) packaging in 0201 (0603 Metric) case format with identical physical dimensions and termination configuration.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for high-temperature applications?

A: The CRCW02015K11FKED is suitable for applications requiring operation up to 155°C. The RC0603F5111CS is rated to 125°C maximum. Selection depends on the specific thermal requirements of the application.
