RC5025J303CS Equivalent & Substitute Parts

Part Overview

The RC5025J303CS is a 30 kOhms ±5% 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 and is RoHS3 compliant with MSL 1 moisture sensitivity rating. Substitute parts are identified when equivalent resistance values and package dimensions are required but alternative manufacturers or improved electrical specifications are preferred for specific application requirements.

Substitute Part Grouping Explanation

Substitution of the RC5025J303CS is based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 30 kOhms
• Package / Case: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance capability
• RoHS3 compliance
• MSL 1 rating

Allowable Variations:

• Tolerance: May be tighter (±1% acceptable for ±5% requirement)
• Power rating: May be equal or higher (0.75W acceptable for 0.667W requirement)
• Manufacturer: Different manufacturer acceptable if all parameters match
• Packaging format: May differ (Tape & Reel acceptable for alternative to standard packaging)

The RC2010FK-0730KL from YAGEO meets all mandatory parameters while providing improved tolerance specification (±1% versus ±5%) and increased power rating (0.75W versus 0.667W).

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-0730KL from YAGEO is a direct substitute for the RC5025J303CS from Samsung Electro-Mechanics. Both components are Active product status and maintain full RoHS3 compliance and REACH unaffected status. The YAGEO substitute provides enhanced specifications with tighter tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W), making it suitable for applications requiring improved accuracy or thermal margin. Physical footprint and package dimensions are equivalent, ensuring PCB layout compatibility. Both components share identical operating temperature range, temperature coefficient, and moisture resistance characteristics. Selection between these parts depends on availability, cost considerations, and application-specific tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0730KL replace RC5025J303CS in existing designs?

A: Yes. Both components share identical resistance value (30 kOhms), package type (2010 / 5025 Metric), physical dimensions (5.00mm x 2.50mm), and operating temperature range (-55°C ~ 155°C). The substitute provides tighter tolerance and higher power rating, which are compatible with applications designed for the original part.

Q: What are the key differences between these two resistors?

A: The primary differences are tolerance specification (±1% for YAGEO versus ±5% for Samsung) and power rating (0.75W for YAGEO versus 0.667W for Samsung). Both differences favor the substitute part. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both the RC5025J303CS and RC2010FK-0730KL are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified as Active product status.

Q: Does package format affect substitution?

A: The RC5025J303CS is supplied in standard packaging, while the RC2010FK-0730KL is supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical compatibility. Component selection should account for manufacturing and procurement requirements.

Q: Are the physical dimensions identical?

A: Yes. Both resistors measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated heights of 0.026" (0.66mm and 0.65mm respectively). PCB footprints and land patterns are compatible.

Q: Can the substitute handle the same thermal conditions?

A: Yes. Both components operate across the identical temperature range of -55°C ~ 155°C with matching temperature coefficient of ±100ppm/°C. The substitute's higher power rating (0.75W) provides additional thermal margin in power dissipation scenarios.
