RC5025F303CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F303CS is a 30 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is RoHS3 compliant with MSL Level 1 rating, indicating unlimited moisture resistance capability.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor. The primary substitute listed maintains identical resistance value, tolerance, and package dimensions while offering increased power rating capability.

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F303CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 30 kOhms (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 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power dissipation rating than the main part, provided all other electrical and mechanical specifications remain identical.

The RC2010FK-0730KL meets all mandatory matching criteria and provides an increased power rating of 0.75W (3/4W) compared to the main part's 0.667W rating, making it a valid substitute for applications requiring equal or greater power handling capability.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-0730KL from YAGEO is a direct substitute for the RC5025F303CS from Samsung Electro-Mechanics based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical resistance value (30 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part's increased power rating (0.75W versus 0.667W) provides additional thermal margin without introducing any electrical incompatibility.

Mechanical Compatibility: Both parts utilize the identical 2010 (5025 Metric) package form factor with matching footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and equivalent seated heights (0.66mm versus 0.65mm). This ensures direct PCB layout compatibility without redesign requirements.

Regulatory Compliance: Both components are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. No compliance degradation occurs with substitution.

Product Status: Both components maintain Active product status, ensuring continued availability and supply chain stability.

Selection of the RC2010FK-0730KL is appropriate for applications where the original RC5025F303CS specification can be met or where the increased power rating provides design margin benefits.

Frequently Asked Questions (FAQ)

Q: Can the RC2010FK-0730KL be used as a direct replacement for RC5025F303CS in existing designs?

A: Yes. The RC2010FK-0730KL is electrically and mechanically compatible with the RC5025F303CS. Both components share identical resistance value, tolerance, package dimensions, and environmental operating range. No PCB layout modifications are required.

Q: What is the significance of the higher power rating on the RC2010FK-0730KL?

A: The RC2010FK-0730KL is rated at 0.75W compared to the RC5025F303CS at 0.667W. This higher rating indicates greater thermal dissipation capability. In applications where the original part operates near its power limit, the substitute provides additional thermal margin. In applications where power dissipation is well below the original rating, both parts perform identically.

Q: Are there any differences in package dimensions that would affect PCB assembly?

A: No. Both components use the 2010 (5025 Metric) package with identical footprint dimensions (5.00mm length × 2.50mm width). Seated heights are equivalent (0.66mm versus 0.65mm), representing negligible variation. Standard pick-and-place equipment and reflow processes are compatible with both parts.

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

A: Yes. Both the RC5025F303CS and RC2010FK-0730KL are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. No compliance differences exist between the two components.

Q: What is the difference between the RC and RC_L series designations?

A: The RC5025F303CS belongs to the RC series (Samsung Electro-Mechanics), while the RC2010FK-0730KL belongs to the RC_L series (YAGEO). These are manufacturer-specific series designations. The series designation does not affect electrical or mechanical compatibility when all other parameters match.

Q: Are there any temperature coefficient differences between these parts?

A: No. Both components specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C ~ 155°C. Temperature stability characteristics are equivalent.

Q: What packaging format is the RC2010FK-0730KL supplied in?

A: The RC2010FK-0730KL is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The RC5025F303CS packaging format is not specified in the provided data. Verify packaging requirements for your procurement and assembly workflow.
