RC5025F4750CS Equivalent & Substitute Parts

Part Overview

The RC5025F4750CS is a 475 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status and is moisture resistant with unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, making it suitable for industrial and commercial applications requiring stable resistive elements with tight tolerance specifications.

Equivalent and substitute parts are identified based on matching critical electrical and mechanical parameters: resistance value (475 Ohms), tolerance (±1%), package form factor (2010/5025 Metric), composition (thick film), and operating temperature range (-55°C to 155°C). Substitute parts may differ in power rating, packaging format, or application-specific certifications while maintaining functional compatibility within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F4750CS is based on the following critical parameters that must be maintained or exceeded:

Mandatory Matching Parameters:

• Resistance value: 475 Ohms (exact match required)
• Tolerance: ±1% (substitute tolerance must be equal or tighter)
• Package form factor: 2010 (5025 Metric) (physical and electrical compatibility requirement)
• Composition: Thick film (determines frequency response and stability characteristics)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Temperature coefficient: ±100ppm/°C (stability specification)

Allowable Variation Parameters:

• Power rating: Substitute must equal or exceed 0.667W; higher power ratings are acceptable
• Packaging format: Original part uses bulk packaging; substitutes may use Tape & Reel (TR) format
• Application certifications: Substitutes may include additional certifications (e.g., AEC-Q200 automotive qualification) without affecting base functionality

The identified substitute CRCW2010475RFKEF meets all mandatory parameters while providing a higher power rating (0.75W vs. 0.667W) and automotive-grade qualification (AEC-Q200), making it suitable for applications requiring enhanced reliability margins.

Parameter Comparison

Engineering Selection Recommendations

RC5025F4750CS (Samsung Electro-Mechanics) - Primary Part

Selection criteria: Use as primary component when Samsung supply chain is established and bulk packaging format is acceptable for manufacturing processes. Active product status ensures continued availability. ROHS3 compliance and REACH unaffected status satisfy standard regulatory requirements. Moisture resistant construction with MSL 1 rating provides unlimited shelf life under standard storage conditions.

CRCW2010475RFKEF (Vishay Dale) - Substitute Part

Selection criteria: Use as direct substitute when Vishay supply chain is preferred or when automotive-grade reliability is required. AEC-Q200 qualification provides enhanced reliability assurance for mission-critical applications. Higher power rating (0.75W vs. 0.667W) offers additional thermal margin in power-dissipation-sensitive circuits. Tape & Reel packaging format is standard for high-volume automated assembly processes. ROHS3 compliance and REACH unaffected status maintain regulatory alignment with primary part.

Substitution Compatibility Assessment:

Both parts are electrically and mechanically interchangeable within the specified parameter envelope. The 0.002" (0.04mm) difference in seated height is within standard PCB assembly tolerances and does not affect functional performance or mechanical fit. Selection between primary and substitute parts should be based on supply availability, packaging format requirements, and application-specific reliability certifications rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010475RFKEF be used as a direct replacement for RC5025F4750CS in existing designs?

A: Yes. Both parts share identical resistance (475 Ohms), tolerance (±1%), package form factor (2010/5025 Metric), composition (thick film), and operating temperature range (-55°C to 155°C). The substitute part's higher power rating (0.75W vs. 0.667W) and automotive qualification do not create compatibility issues. Physical dimensions are equivalent within standard assembly tolerances.

Q: What is the significance of the power rating difference (0.667W vs. 0.75W)?

A: The substitute part's higher power rating indicates greater thermal capacity and allows operation at higher current levels without exceeding temperature limits. In circuits designed for the original 0.667W specification, the substitute part operates with additional thermal margin, which is beneficial for reliability. No circuit redesign is required.

Q: Does the AEC-Q200 automotive qualification on the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 is an additional qualification that indicates enhanced reliability testing and quality assurance. Parts meeting automotive standards are fully compatible with industrial and commercial applications. The qualification does not restrict use to automotive applications only.

Q: Are the packaging format differences (bulk vs. Tape & Reel) significant for substitution?

A: Packaging format affects manufacturing process compatibility, not electrical or mechanical performance. Bulk packaging (original part) is suitable for manual assembly or small-batch processes. Tape & Reel format (substitute part) is optimized for automated high-volume assembly. Selection should match manufacturing process requirements. Both formats contain identical components.

Q: What is the importance of matching the 2010 (5025 Metric) package specification?

A: The package form factor determines physical fit on printed circuit boards and electrical connection compatibility. The 2010 package specifies exact dimensions (5.00mm length x 2.50mm width), pad spacing, and termination configuration. Substituting with a different package size (e.g., 1206, 0805) requires PCB redesign and is not considered a direct substitute.

Q: Are there any temperature-related performance differences between the two parts?

A: No. Both parts share identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C). Resistance stability across the full temperature range is equivalent. The substitute part's higher power rating provides additional thermal headroom but does not alter temperature-dependent performance characteristics.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean for component handling?

A: MSL 1 rating indicates the component has unlimited shelf life under standard storage conditions (typically 30°C/85% relative humidity). No special moisture-control packaging, baking procedures, or time-limited storage windows are required. Both the primary and substitute parts can be stored and handled using standard component management practices.

Q: Can the substitute part be used in applications where the original part is specified in design documentation?

A: Yes, provided the design documentation specifies the critical parameters (475 Ohms, ±1%, 2010 package, thick film, -55°C to 155°C) rather than the specific manufacturer part number. If the design calls for the exact Samsung part number, engineering change documentation should be prepared to formally approve the substitution. The electrical and mechanical equivalence supports such approvals.
