Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4R75CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 4.75 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.063W minimum (1/16W)

Mechanical Equivalence Requirements:

• Package format: 0402 (1005 Metric) (exact match)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height seated maximum: 0.016" (0.40mm)
• Termination count: 2 (exact match)

Compliance & Environmental Requirements:

• Composition: Thick Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The RMCF0402FT4R75 from Stackpole Electronics Inc meets all mandatory electrical, mechanical, and compliance criteria for direct substitution. Packaging format differs (Tape & Reel versus Cut Tape) but does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0402FT4R75 (Stackpole Electronics Inc) is a direct electrical and mechanical equivalent to the RC1005F4R75CS (Samsung Electro-Mechanics). Both components satisfy identical specifications for resistance value, tolerance, power rating, package dimensions, and operating temperature range.

Compliance Status: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory equivalence for applications requiring these certifications.

Performance Characteristics: The Stackpole RMCF0402FT4R75 demonstrates a superior temperature coefficient of ±200ppm/°C compared to the Samsung RC1005F4R75CS at ±300ppm/°C. This represents improved temperature stability across the operating range.

Automotive Qualification: The Stackpole part carries AEC-Q200 automotive qualification, which is not specified for the Samsung part. This qualification is relevant only for applications requiring automotive-grade component certification.

Packaging Consideration: The primary difference is packaging format. The Samsung part is supplied in Cut Tape (CT) format with 1225 pieces in stock, while the Stackpole equivalent is supplied in Tape & Reel (TR) format with 51254 pieces available. Both formats are compatible with standard pick-and-place assembly equipment; format selection depends on production volume and assembly line configuration.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0402FT4R75 replace the RC1005F4R75CS in existing designs?

A: Yes. Both components are electrically and mechanically equivalent. They share identical resistance (4.75 Ohms), tolerance (±1%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). Direct substitution is valid without circuit redesign.

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

A: Cut Tape (CT) packaging supplies components in shorter tape segments, typically used for lower-volume orders or manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain the same component; packaging selection depends on production volume and assembly equipment capability.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: No. The Stackpole part's superior temperature coefficient (±200ppm/°C versus ±300ppm/°C) represents enhanced performance, not a limitation. Both values fall within acceptable ranges for standard thick film resistor applications. The Stackpole part is suitable for applications requiring tighter temperature stability.

Q: Is AEC-Q200 qualification required for substitution?

A: No. AEC-Q200 is an automotive qualification present on the Stackpole part but not specified for the Samsung part. This qualification is relevant only if your application requires automotive-grade components. For non-automotive applications, both parts are equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.039" L x 0.020" W (1.00mm x 0.50mm) with a maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable in PCB layouts designed for 0402 (1005 Metric) package format.

Q: What compliance certifications apply to both parts?

A: Both the RC1005F4R75CS and RMCF0402FT4R75 are ROHS3 compliant and REACH unaffected. Both carry unlimited moisture sensitivity level (MSL 1), indicating no special moisture handling requirements during storage or assembly.
