Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F4750CS are classified into two categories based on application requirements and compliance certifications:

Direct Substitutes (Electrical and Mechanical Equivalence): Parts that match all critical parameters including resistance value (475 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and moisture sensitivity level (MSL 1). These parts are interchangeable without circuit redesign.

Similar Substitutes (Enhanced Certifications): Parts that maintain all electrical and mechanical specifications but include additional automotive-grade AEC-Q200 certification. These parts are suitable for applications requiring automotive qualification while maintaining full compatibility with standard industrial designs.

Key Parameters Determining Substitution:

• Resistance: 475 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C to 155°C (exact match required)
• Terminations: 2 (exact match required)

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications (ROHS3 Compliant Required):

The CR0603-FX-4750ELF (Bourns Inc.) and RC0603FR-07475RL (YAGEO) are direct electrical and mechanical equivalents to the RC1608F4750CS. Both maintain identical electrical specifications and ROHS3 compliance. Selection between these options depends on packaging preference: CR0603-FX-4750ELF is supplied in Tape & Reel format, while RC0603FR-07475RL is available in Cut Tape & Digi-Reel format.

For Automotive and Enhanced Reliability Applications (AEC-Q200 Certification Required):

The AC0603FR-07475RL (YAGEO), CRCW0603475RFKEA (Vishay Dale), ERJ-3EKF4750V (Panasonic Electronic Components), RMCF0603FG475R (Stackpole Electronics Inc), and RMCF0603FT475R (Stackpole Electronics Inc) all provide AEC-Q200 automotive-grade certification while maintaining full electrical and mechanical compatibility. These parts are suitable for automotive, medical, and mission-critical applications requiring enhanced qualification standards.

Compliance Considerations:

The CRCW0603475RFKTA (Vishay Dale) is RoHS non-compliant and REACH Affected. This part should be selected only when legacy design requirements or specific supply chain constraints mandate its use, as it does not meet current environmental compliance standards.

Packaging Format Selection:

For automated assembly processes requiring Tape & Reel packaging, select from CR0603-FX-4750ELF, AC0603FR-07475RL, CRCW0603475RFKEA, CRCW0603475RFKTA, ERJ-3EKF4750V, or RMCF0603FT475R. For manual assembly or cut tape applications, RC0603FR-07475RL and RMCF0603FG475R are available in alternative packaging formats.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F4750CS with any of the listed equivalent parts without circuit redesign?

A: Yes, all listed parts maintain identical electrical specifications (475 Ohms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical dimensions (0603 package, 2 terminations). Direct substitution is possible without circuit modification. However, verify packaging format compatibility with your assembly process.

Q: What is the difference between Direct Substitutes and Similar Substitutes?

A: Direct substitutes (CR0603-FX-4750ELF, RC0603FR-07475RL) match all electrical and mechanical parameters without additional certifications. Similar substitutes include AEC-Q200 automotive-grade certification, making them suitable for automotive and high-reliability applications while maintaining full compatibility with standard designs.

Q: Is the CRCW0603475RFKTA suitable for new designs?

A: The CRCW0603475RFKTA is RoHS non-compliant and REACH Affected. It should not be selected for new designs unless legacy compatibility or specific supply chain requirements mandate its use. ROHS3-compliant alternatives are recommended for all new product development.

Q: How do I choose between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is standard for automated pick-and-place assembly equipment. Cut Tape & Digi-Reel formats are suitable for manual assembly, lower-volume production, or when specific reel quantities are not required. Verify your assembly equipment compatibility before selecting packaging format.

Q: Are all substitute parts available in the same moisture sensitivity level?

A: Yes, all listed substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level, identical to the RC1608F4750CS. No special moisture handling or baking procedures are required for any of these parts.

Q: Can I use AEC-Q200 certified parts in non-automotive applications?

A: Yes, AEC-Q200 certified parts exceed standard industrial requirements and are fully compatible with non-automotive applications. Using automotive-grade components in standard industrial designs provides enhanced reliability margin without circuit compatibility issues.

Q: What are the physical dimension differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package specification. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width ranges from 0.031" to 0.033" (0.80mm to 0.85mm), and height ranges from 0.020" to 0.022" (0.50mm to 0.55mm). These variations remain within standard PCB pad design tolerances and do not affect assembly compatibility.
