Substitute Part Grouping Explanation

Substitution of the RC5025F180CS is permissible with the RC2010FK-0718RL based on the following alignment of critical parameters:

Electrical Equivalence:

• Identical resistance value: 18 Ohms
• Identical tolerance specification: ±1%
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C to 155°C

Mechanical & Package Equivalence:

• Identical package designation: 2010 (5025 Metric)
• Identical physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Identical termination count: 2
• Equivalent seated height: 0.026" maximum

Material & Compliance Equivalence:

• Identical composition: Thick Film
• Identical moisture resistance feature
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected

Upgrade Consideration: The RC2010FK-0718RL provides increased power dissipation capability (0.75W vs. 0.667W), representing a rated power upgrade while maintaining all other specifications. This upgrade is functionally compatible for applications where the original power rating is adequate, as the substitute accommodates equal or lower power requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F180CS): The Samsung Electro-Mechanics RC5025F180CS remains the specified component for applications where the original design parameters and manufacturer designation are required. Active product status and current inventory availability (707 pcs) support continued procurement.

Substitute Selection (RC2010FK-0718RL): The YAGEO RC2010FK-0718RL is functionally equivalent and directly substitutable in all applications where the RC5025F180CS is specified. The increased power rating (0.75W vs. 0.667W) provides design margin without introducing incompatibility. Both components maintain identical electrical performance, thermal characteristics, and regulatory compliance (RoHS3, REACH Unaffected). The substitute is available in higher inventory volume (6154 pcs) and supplied in Tape & Reel packaging format.

Compliance Basis: Both components satisfy identical regulatory requirements: RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1). No additional qualification or testing is required based on compliance certifications alone.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0718RL replace RC5025F180CS in existing designs without modification?

A: Yes. The RC2010FK-0718RL is a direct substitute. Both components share identical resistance (18 Ohms), tolerance (±1%), package (2010/5025 Metric), physical dimensions, temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and composition (thick film). The substitute's higher power rating (0.75W vs. 0.667W) does not create incompatibility for applications designed around the original 0.667W specification.

Q: What is the difference in power rating between these parts?

A: The RC5025F180CS is rated at 0.667W (2/3W), while the RC2010FK-0718RL is rated at 0.75W (3/4W). This represents an 11.4% increase in maximum power dissipation capability. For applications operating at or below the original 0.667W specification, this difference is not operationally significant and does not affect circuit performance.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.197" L x 0.098" W (5.00mm x 2.50mm) and have equivalent maximum seated heights (0.66mm vs. 0.65mm). They are mechanically interchangeable in PCB layouts designed for the 2010 (5025 Metric) package.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC5025F180CS and RC2010FK-0718RL are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. No additional compliance documentation or qualification is required for substitution.

Q: What is the packaging difference?

A: The RC5025F180CS is supplied in standard packaging format (not specified in detail). The RC2010FK-0718RL is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. Both formats are compatible with automated pick-and-place equipment.

Q: Are the temperature coefficients identical?

A: Yes. Both components specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C. Thermal performance and stability are equivalent.

Q: Can I use RC2010FK-0718RL in applications requiring the exact original manufacturer part?

A: No. If design specifications, procurement requirements, or quality agreements mandate the Samsung Electro-Mechanics RC5025F180CS specifically, the substitute cannot be used without formal design change authorization and documentation update.
