RC5025F300CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F300CS is a 30 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F300CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: MSL 1 (minimum requirement)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power dissipation capacity
• Packaging Format: Tape & Reel (TR) acceptable for equivalent bulk component selection
• Manufacturer: Different manufacturers permitted if all electrical and mechanical specifications align

The RC2010FK-0730RL from YAGEO qualifies as a substitute because it maintains all mandatory parameters while providing increased power rating (0.75W vs. 0.667W), representing a higher-capacity alternative within the same mechanical footprint.

Parameter Comparison

Engineering Selection Recommendations

RC5025F300CS (Samsung Electro-Mechanics):

• Primary selection when Samsung component availability and supply chain continuity are prioritized
• Active product status with established manufacturing support
• Suitable for applications with power dissipation requirements at or below 0.667W
• ROHS3 and REACH compliance confirmed for regulated markets

RC2010FK-0730RL (YAGEO):

• Alternative selection when higher power margin is required within the same package footprint
• 0.75W rating provides 12.5% additional thermal capacity compared to primary part
• Active product status with higher inventory availability (5042 Pcs vs. 784 Pcs)
• Identical electrical performance and environmental specifications
• Tape & Reel packaging suitable for automated assembly processes
• ROHS3 and REACH compliance confirmed for regulated markets

Both parts are functionally interchangeable in circuit designs where the 30 Ohm ±1% specification and 2010 package are required. Selection between them depends on supply availability, packaging format requirements, and thermal design margin preferences.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0730RL replace RC5025F300CS in all applications?

A: Yes, within the scope of electrical and mechanical specifications. The YAGEO part maintains identical resistance, tolerance, temperature coefficient, and operating range. The higher power rating (0.75W vs. 0.667W) does not create incompatibility; it provides additional thermal capacity. Physical dimensions and package type are equivalent, ensuring PCB layout compatibility.

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

A: The power rating indicates maximum continuous power dissipation capability. RC2010FK-0730RL can safely dissipate 12.5% more power than RC5025F300CS. In circuits where actual power dissipation is below 0.667W, both parts perform identically. The substitute part is suitable for designs with higher current demands or thermal stress conditions.

Q: Are the physical dimensions truly identical?

A: Yes. Both parts conform to the 2010 (5025 Metric) package standard with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated heights are equivalent (0.66mm vs. 0.65mm), representing negligible variation within manufacturing tolerance. PCB footprints and assembly processes are interchangeable.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (bulk vs. Tape & Reel) does not affect electrical or mechanical compatibility. RC5025F300CS is supplied in standard packaging, while RC2010FK-0730RL is available in Tape & Reel format. Selection depends on assembly process requirements and inventory management preferences, not component performance.

Q: Are both parts compliant with RoHS3 and REACH regulations?

A: Yes. Both RC5025F300CS and RC2010FK-0730RL carry ROHS3 Compliant status and REACH Unaffected designation. Both are suitable for applications in regulated markets requiring environmental compliance documentation.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity classification. Components with this rating require no special moisture control during storage, handling, or assembly. Both parts can be stored and processed under standard industrial conditions without desiccant packaging or baking procedures.

Q: Can these parts be used interchangeably on existing PCBs without design changes?

A: Yes. Identical package dimensions, footprint compatibility, and electrical specifications allow direct substitution on existing PCBs. No circuit redesign, layout modification, or assembly process adjustment is required.
