RC5025F47R5CS Equivalent & Substitute Parts

Part Overview

The RC5025F47R5CS is a 47.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F47R5CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 47.5 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1 or better

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power dissipation capacity without affecting circuit compatibility, provided all other parameters remain constant.

The CRCW201047R5FKEF from Vishay Dale meets all mandatory matching criteria and exceeds the power rating specification (0.75W versus 0.667W), making it a valid electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The CRCW201047R5FKEF is electrically and mechanically compatible with the RC5025F47R5CS for direct substitution in applications requiring a 47.5 Ohm ±1% thick film resistor in 2010 package format. Both components maintain identical electrical characteristics across the specified operating temperature range and comply with ROHS3 environmental standards.

The Vishay Dale substitute provides higher power dissipation capacity (0.75W versus 0.667W), which presents no compatibility concerns in circuits designed for the original Samsung component. The increased power rating offers additional thermal margin without introducing any electrical or mechanical incompatibilities.

Both parts are classified as Active product status, ensuring continued availability and manufacturing support. Selection between these components may be based on supply chain availability, packaging requirements (the substitute is available in Tape & Reel format), or application-specific certifications such as AEC-Q200 automotive qualification present in the Vishay Dale variant.

Frequently Asked Questions (FAQ)

Q: Can the CRCW201047R5FKEF replace the RC5025F47R5CS in existing designs?

A: Yes. Both components share identical resistance value, tolerance, package dimensions, and operating temperature range. The substitute's higher power rating (0.75W) does not create compatibility issues in circuits designed for the original 0.667W component.

Q: Are the physical dimensions identical between these parts?

A: The package format is identical (2010 / 5025 Metric). Both components measure 0.197" L × 0.098" W (5.00mm × 2.50mm). Maximum seated heights differ slightly (0.026" for Samsung versus 0.028" for Vishay Dale), which remains within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: What is the significance of the higher power rating in the substitute?

A: The CRCW201047R5FKEF's 0.75W rating provides additional thermal capacity compared to the 0.667W original specification. This allows the component to dissipate more power without exceeding temperature limits, offering improved reliability margin in applications operating near maximum power dissipation levels.

Q: Are both components RoHS compliant?

A: Yes. Both the RC5025F47R5CS and CRCW201047R5FKEF are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity ratings, meeting identical environmental and regulatory requirements.

Q: What packaging formats are available?

A: The RC5025F47R5CS is supplied in standard packaging. The CRCW201047R5FKEF is available in Tape & Reel (TR) format, which may be advantageous for high-volume automated assembly operations.

Q: Does the Vishay Dale part include automotive qualification?

A: Yes. The CRCW201047R5FKEF carries AEC-Q200 automotive qualification. This certification is not specified for the Samsung component and may be relevant for applications requiring automotive-grade component validation.
