Equivalent & Substitute Parts for RC0603F433CS

Part Overview

The RC0603F433CS is a 43 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RC0603F433CS serves as a precision resistive element in applications requiring stable resistance values across industrial temperature ranges. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when supply chain diversification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC0603F433CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 43 kOhms (exact match required)
• Tolerance: ±1% (precision class equivalence)
• Power rating: 0.05W / 1/20W (thermal rating equivalence)
• Package: 0201 (0603 Metric) (physical and electrical footprint equivalence)
• Composition: Thick Film (manufacturing process equivalence)
• Termination count: 2 (circuit interface equivalence)
• RoHS3 compliance (regulatory equivalence)
• MSL 1 rating (moisture handling equivalence)

Allowable Variation Parameters:

• Temperature coefficient: May vary within industrial specifications
• Operating temperature range: May extend beyond the main part specification
• Packaging format: Cut Tape (CT) or Tape & Reel (TR) formats are interchangeable for component selection purposes

The substitute part CRCW020143K0FKED from Vishay Dale meets all mandatory matching parameters and is therefore classified as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CRCW020143K0FKED from Vishay Dale is a direct substitute for the RC0603F433CS based on electrical and mechanical equivalence. Both components are Active product status with full RoHS3 compliance and MSL 1 rating, confirming regulatory and environmental compatibility.

The substitute part demonstrates superior performance characteristics in two areas: a lower temperature coefficient (±100ppm/°C versus ±250ppm/°C) and an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). These characteristics do not create incompatibility; rather, they indicate the substitute part operates within a broader specification envelope suitable for the same applications.

Packaging format differs between the main part (Cut Tape) and substitute (Tape & Reel). This variation affects procurement and assembly logistics but does not impact electrical or mechanical performance. Component selection should be based on assembly process requirements and inventory management practices.

Both parts carry identical HTSUS and ECCN classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CRCW020143K0FKED replace RC0603F433CS in existing designs without modification?

A: Yes. Both components share identical electrical specifications (43 kOhms ±1%, 0.05W), physical dimensions (0201 package), and regulatory compliance (RoHS3, MSL 1). No circuit design changes are required.

Q: What is the significance of the different temperature coefficients?

A: The substitute part exhibits a lower temperature coefficient (±100ppm/°C) compared to the main part (±250ppm/°C). This indicates the substitute maintains more stable resistance values across temperature variations. This difference does not create incompatibility; it represents an allowable variation within thick film resistor manufacturing specifications.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The substitute part operates across -55°C to 155°C, which encompasses the main part's -55°C to 125°C range. Extended operating range does not create incompatibility for applications designed within the original temperature specification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

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

Q: Are there any compliance or certification differences between these parts?

A: No. Both components carry identical RoHS3 compliance, MSL 1 rating, HTSUS code (8533.21.0030), and ECCN classification (EAR99). Regulatory and environmental certifications are equivalent.

Q: Can these parts be used interchangeably in high-precision applications?

A: Yes, within the tolerance specifications. Both parts are rated ±1% tolerance. The substitute part's lower temperature coefficient may provide superior stability in temperature-sensitive applications, but both parts meet the ±1% precision requirement.

Q: What inventory considerations apply to substitution?

A: The RC0603F433CS has 2,373 pieces in stock. The CRCW020143K0FKED has 12,701 pieces in stock. Substitute sourcing provides significantly higher inventory availability for supply chain continuity.
