Key Parameters

Substitute Part Grouping Explanation

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

Critical Matching Parameters:

• Resistance value: 3.01 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package designation: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Number of terminations: 2 (exact match required)

Acceptable Variation Parameters:

• Temperature coefficient: ±250ppm/°C (main) vs. ±100ppm/°C (substitute) — substitute exhibits superior stability
• Operating temperature upper limit: 125°C (main) vs. 155°C (substitute) — substitute provides extended thermal range
• Composition features: Moisture Resistant (main) vs. standard thick film (substitute) — both meet MSL 1 classification

Compliance Alignment:

• RoHS3 Compliant (both parts)
• REACH Unaffected (both parts)
• ECCN: EAR99 (both parts)
• HTSUS: 8533.21.0030 (both parts)

The substitute part CRCW02013K01FKED meets all critical electrical and mechanical requirements while offering improved temperature performance characteristics.

Engineering Selection Recommendations

Primary Selection (RC0603F3011CS): The Samsung Electro-Mechanics RC0603F3011CS is the specified original component. Selection is appropriate when design documentation explicitly requires this manufacturer part number or when moisture-resistant thick film construction is a documented design requirement. Current inventory status: 750 Pcs New Original In Stock.

Substitute Selection (CRCW02013K01FKED): The Vishay Dale CRCW02013K01FKED is a direct electrical and mechanical equivalent with enhanced performance characteristics. This substitute is appropriate when:

• Original part availability is constrained
• Extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C) provides design margin
• Superior temperature coefficient (±100ppm/°C vs. ±250ppm/°C) improves circuit stability
• Both parts maintain identical RoHS3 and REACH compliance status
• Both parts carry MSL 1 (Unlimited) moisture sensitivity classification

Current inventory status: 20,363 Pcs New Original In Stock.

Compliance Verification: Both parts satisfy ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classifications. No regulatory barriers exist for substitution in applications where the original specification permits equivalent thick film 0201 package resistors with ±1% tolerance and 0.05W power rating.

Frequently Asked Questions (FAQ)

Q: Can CRCW02013K01FKED be used as a direct replacement for RC0603F3011CS in all applications?

A: Yes, within the constraints of the original design specification. Both parts are electrically identical (3.01 kOhms ±1%, 0.05W) and mechanically identical (0201 package, 0.60mm x 0.30mm). The substitute offers extended temperature range and improved temperature coefficient, which are compatible with or superior to the original specification. Verify that your design does not explicitly require Samsung Electro-Mechanics as the sole source manufacturer.

Q: What is the difference in temperature coefficient between these parts?

A: The RC0603F3011CS has a temperature coefficient of ±250ppm/°C, while the CRCW02013K01FKED has ±100ppm/°C. The substitute exhibits superior temperature stability, meaning its resistance value changes less with temperature variations. This is a beneficial characteristic for precision analog circuits.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and reflow profiles are interchangeable.

Q: Do both parts have the same moisture sensitivity classification?

A: Yes. Both RC0603F3011CS and CRCW02013K01FKED are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply to both parts.

Q: What is the operating temperature difference?

A: The RC0603F3011CS operates from -55°C to 125°C, while the CRCW02013K01FKED operates from -55°C to 155°C. The substitute provides a 30°C higher upper temperature limit, offering additional thermal margin for high-temperature applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC0603F3011CS and CRCW02013K01FKED are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the tolerance specification for both parts?

A: Both parts are specified at ±1% tolerance on the 3.01 kOhms resistance value. This tight tolerance is suitable for precision applications requiring accurate resistor values.

Q: Can I mix these parts in the same production batch?

A: From an electrical and mechanical standpoint, yes. Both parts are functionally equivalent and will perform identically in circuit operation. However, verify your quality assurance and traceability procedures, as the parts carry different manufacturer part numbers and may require separate documentation tracking.
