Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Primary Matching Criteria:

• Resistance value: 4.7 Ohms (exact match required)
• Power rating: 0.063W / 1/16W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Physical dimensions: 0.039" L x 0.020" W / 1.00mm x 0.50mm (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or wider range acceptable)
• Composition: Thick Film (exact match required)

Secondary Variation Parameters (Allowed Differences):

• Tolerance grade: ±5% (main part) or ±1% (substitute acceptable; tighter tolerance is compatible)
• Temperature coefficient: ±300ppm/°C (main part) or ±200ppm/°C (substitute acceptable; lower coefficient indicates improved stability)
• Manufacturer: Samsung Electro-Mechanics, YAGEO, or Stackpole Electronics Inc
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Specialized certifications: Automotive AEC-Q200 (optional enhancement)

All identified substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and Active product status. Substitutes with tighter tolerance (±1%) or lower temperature coefficient (±200ppm/°C) represent performance upgrades while maintaining full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance Grade):

RC0402JR-074R7L (YAGEO) and RMCF0402JT4R70 (Stackpole Electronics Inc) are direct functional equivalents to RC1005J4R7CS, maintaining the ±5% tolerance specification. Both parts are Active status with ROHS3 compliance and MSL Level 1 rating. RMCF0402JT4R70 includes Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability standards.

Performance-Enhanced Substitutes (Tighter Tolerance):

RC0402FR-074R7L (YAGEO) and RMCF0402FT4R70 (Stackpole Electronics Inc) offer ±1% tolerance with improved temperature coefficient (±200ppm/°C versus ±300ppm/°C). These parts are suitable for applications requiring higher precision and improved thermal stability. RMCF0402FT4R70 combines ±1% tolerance with Automotive AEC-Q200 certification.

Packaging Considerations:

RC1005J4R7CS is supplied in Tape & Reel (TR) format. YAGEO substitutes (RC0402JR-074R7L and RC0402FR-074R7L) are available in Cut Tape (CT) & Digi-Reel® format. Stackpole substitutes maintain TR packaging (RMCF0402FT4R70) or CT & Digi-Reel® format (RMCF0402JT4R70). Packaging format selection depends on assembly process requirements and inventory management protocols.

All substitute parts maintain identical physical dimensions, electrical ratings, and environmental compliance specifications, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-074R7L replace RC1005J4R7CS in my circuit?

A: Yes. RC0402FR-074R7L is a direct functional substitute with identical resistance (4.7 Ohms), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). The ±1% tolerance of RC0402FR-074R7L is tighter than the ±5% specification of RC1005J4R7CS, making it compatible for all applications where the original part is specified. The lower temperature coefficient (±200ppm/°C) provides improved thermal stability.

Q: What is the difference between YAGEO and Stackpole substitute parts?

A: YAGEO RC0402JR-074R7L and RC0402FR-074R7L are standard industrial-grade thick film resistors with moisture-resistant construction. Stackpole RMCF0402JT4R70 and RMCF0402FT4R70 are Automotive AEC-Q200 certified, meeting automotive industry reliability and qualification standards. Both manufacturers provide ROHS3 compliance and MSL Level 1 rating. Selection depends on application requirements: industrial applications can use YAGEO parts; automotive or high-reliability applications benefit from Stackpole AEC-Q200 certification.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All substitute parts maintain identical 0402 (1005 Metric) package dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). Board layout and assembly processes require no modification when substituting between these parts.

Q: What does ±1% tolerance mean compared to ±5%?

A: Tolerance specifies the acceptable deviation from the nominal 4.7 Ohm resistance value. ±5% tolerance allows resistance between 4.465 Ohms and 4.935 Ohms. ±1% tolerance allows resistance between 4.653 Ohms and 4.747 Ohms. Tighter tolerance (±1%) provides more precise resistance values, beneficial for circuits requiring accurate impedance matching or precision signal conditioning. Standard tolerance (±5%) is suitable for general-purpose applications where component variation has minimal circuit impact.

Q: What is the significance of temperature coefficient?

A: Temperature coefficient (±300ppm/°C versus ±200ppm/°C) indicates how resistance changes with temperature. Lower temperature coefficient means more stable resistance across the operating temperature range (-55°C ~ 155°C). Substitute parts with ±200ppm/°C provide improved performance in temperature-sensitive applications, though both specifications meet the stated operating range.

Q: Can I use Tape & Reel packaging interchangeably with Cut Tape & Digi-Reel® packaging?

A: Packaging format affects supply and assembly logistics, not electrical or mechanical compatibility. Tape & Reel (TR) is continuous reel format for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® is pre-cut tape format for lower-volume or mixed-component assembly. Component selection should align with your assembly equipment and inventory management requirements. Electrical and physical specifications are identical regardless of packaging format.

Q: Is ROHS3 compliance important for my application?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All listed parts (RC1005J4R7CS and all substitutes) are ROHS3 compliant. This is standard for commercial and industrial applications. Compliance status is identical across all parts in this reference.

Q: What does MSL Level 1 (Unlimited) mean?

A: Moisture Sensitivity Level (MSL) 1 indicates the component has unlimited shelf life and requires no special moisture-control storage or handling. All parts in this reference carry MSL Level 1 rating, eliminating moisture-related storage or assembly constraints. Standard warehouse storage conditions are acceptable.
