RC5025F475CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F475CS is a 4.7 MOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts become necessary when Samsung Electro-Mechanics inventory is unavailable, when supply chain optimization requires secondary sourcing, or when design specifications permit higher power ratings within the same package footprint.

Substitute Part Grouping Explanation

Substitution of the RC5025F475CS is permissible only when the replacement component satisfies all critical parameters: identical resistance value (4.7 MOhms), matching or superior tolerance (±1%), equal or higher power rating within the same 2010 package footprint, identical temperature coefficient (±100ppm/°C), matching operating temperature range (-55°C ~ 155°C), and equivalent or superior regulatory compliance (ROHS3 Compliant minimum).

The RC2010FK-074M7L from YAGEO qualifies as a direct substitute because it maintains all critical electrical parameters while providing an upgraded power rating (0.75W versus 0.667W). Both components are thick film resistors with identical resistance, tolerance, temperature coefficient, and operating temperature specifications. Both maintain 2010 package dimensions and full RoHS3 compliance with MSL 1 rating. The higher power rating of the substitute provides additional thermal margin without affecting circuit functionality or introducing incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-074M7L represents a valid equivalent substitute for the RC5025F475CS based on electrical and mechanical compatibility. Both components maintain Active product status with full regulatory compliance under RoHS3 and REACH standards. The YAGEO substitute provides identical electrical performance with enhanced thermal capability (0.75W versus 0.667W), which increases design margin without introducing circuit incompatibility. The 2010 package footprint remains identical, ensuring PCB layout compatibility. Physical height variation (0.65mm maximum versus 0.66mm maximum) is negligible for surface mount assembly. Selection between these components should be based on availability, supply chain requirements, packaging format preference (bulk versus tape & reel), and cost considerations. Both components are suitable for applications requiring high-impedance resistive elements with tight tolerance and stable temperature characteristics across the full military and industrial temperature range.

Frequently Asked Questions (FAQ)

Q: Can the RC2010FK-074M7L replace the RC5025F475CS in existing designs without modification?

A: Yes. The substitute maintains identical resistance value, tolerance, temperature coefficient, and operating temperature range. The higher power rating (0.75W versus 0.667W) provides additional thermal margin. Physical dimensions are compatible with 2010 package footprints. No circuit redesign is required.

Q: What is the significance of the power rating difference between these components?

A: The RC2010FK-074M7L is rated for 0.75W compared to the RC5025F475CS at 0.667W. This represents a 12.5% increase in power dissipation capability. If the original design operates the resistor below 0.667W, the substitute will operate at lower temperature rise, improving reliability and extending component life. If the design requires exactly 0.667W dissipation, the substitute remains fully functional.

Q: Are there packaging considerations when switching from RC5025F475CS to RC2010FK-074M7L?

A: The RC5025F475CS is supplied in bulk packaging, while the RC2010FK-074M7L is supplied in Tape & Reel (TR) format. This affects procurement, handling, and assembly processes. Tape & Reel format is standard for automated pick-and-place assembly. Bulk format requires manual handling or tray feeding. Verify your assembly process compatibility before procurement.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the RC5025F475CS and RC2010FK-074M7L are RoHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, requiring no special storage or handling precautions. Compliance documentation is equivalent for both components.

Q: What is the temperature coefficient specification and why does it matter?

A: Both components specify ±100ppm/°C temperature coefficient. This means the resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. For a 4.7 MOhms resistor, this translates to approximately 470 ohms maximum change across the full -55°C to 155°C operating range. This specification is identical between both components, ensuring equivalent stability performance.

Q: Can the RC2010FK-074M7L be used in high-temperature applications?

A: Yes. The RC2010FK-074M7L maintains full specifications across the -55°C to 155°C operating temperature range, identical to the RC5025F475CS. Both components are rated for industrial and military temperature environments. Verify that your specific application does not require extended temperature operation beyond 155°C maximum.
