Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F753CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 75 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Composition: Thick Film (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Allowable Variation Parameters:

• Temperature Coefficient: ±250ppm/°C (main) vs. ±100ppm/°C (substitute) — tighter specification acceptable
• Operating Temperature Range: -55°C ~ 125°C (main) vs. -55°C ~ 155°C (substitute) — extended range acceptable
• Packaging format: Cut Tape (CT) vs. Tape & Reel (TR) — logistics variation only

The substitute part CRCW020175K0FKED meets all critical matching parameters and demonstrates superior temperature coefficient performance and extended operating range, qualifying it as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC0603F753CS): The RC0603F753CS maintains Active product status with established supply chain availability (1017 Pcs in stock). This component is suitable for applications requiring standard operating temperature range (-55°C ~ 125°C) with standard temperature coefficient performance (±250ppm/°C). Full RoHS3 compliance and MSL 1 rating support unrestricted handling and storage protocols.

Substitute Component (CRCW020175K0FKED): The CRCW020175K0FKED is qualified as a direct substitute based on identical electrical specifications, mechanical dimensions, and regulatory compliance. The substitute demonstrates enhanced performance characteristics: tighter temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C). These performance enhancements present no compatibility risk and are fully backward compatible with the original design. The substitute is available in higher inventory volume (62239 Pcs), supporting extended production runs. Both components carry identical ROHS3, REACH, and ECCN classifications, ensuring regulatory equivalence.

Selection between these components is determined by supply availability, lead time requirements, and packaging format preference (Cut Tape vs. Tape & Reel). No circuit redesign or performance validation is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can CRCW020175K0FKED replace RC0603F753CS in existing designs without modification?

A: Yes. Both components share identical resistance value (75 kOhms), tolerance (±1%), power rating (0.05W), package dimensions (0201 / 0603 Metric), and composition (Thick Film). The substitute meets or exceeds all critical electrical and mechanical specifications. No circuit redesign is required.

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

A: The RC0603F753CS specifies ±250ppm/°C temperature coefficient, while the CRCW020175K0FKED specifies ±100ppm/°C. The substitute exhibits tighter temperature stability, representing improved performance. This difference does not create incompatibility; the substitute is suitable for applications originally designed for the primary component.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in 0201 (0603 Metric) format 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 assembly processes are interchangeable.

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

A: Cut Tape (CT) packaging is supplied in individual tape segments suitable for small-volume or manual assembly operations. Tape & Reel (TR) packaging is supplied on continuous reels optimized for high-speed automated assembly equipment. Both formats contain identical components; packaging selection depends on production volume and assembly equipment capability.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both RC0603F753CS and CRCW020175K0FKED are ROHS3 Compliant, REACH Unaffected, classified as EAR99 for export control, and assigned identical HTSUS code 8533.21.0030. Regulatory equivalence is confirmed.

Q: What is MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 (Unlimited) indicates the component requires no special moisture control during storage, handling, or assembly. Both components carry this classification, eliminating moisture-related handling restrictions and enabling standard warehouse storage protocols.

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

A: Yes. Electrical and mechanical equivalence permits interchangeable use within the same assembly. However, component traceability documentation should reflect the specific manufacturer and part number used in each unit for warranty and field service purposes.

Q: What is the operating temperature range difference?

A: The RC0603F753CS operates from -55°C to 125°C, while the CRCW020175K0FKED operates from -55°C to 155°C. The substitute supports extended high-temperature operation. For applications within the primary component's range (-55°C ~ 125°C), both are functionally equivalent. For applications requiring operation above 125°C, only the substitute is qualified.
