RC5025F2430CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2430CS is a 243 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the same package footprint, allowing for direct board-level replacement in applications where component availability or supply chain requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2430CS are qualified based on the following criteria:

Electrical Parameters (Critical Match):

• Resistance value: 243 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or superior range required)

Mechanical Parameters (Critical Match):

• Package / Case: 2010 (5025 Metric) (exact match required for PCB footprint compatibility)
• Composition: Thick Film (exact match required)

Power Rating (Upgrade Acceptable):

• Original part: 0.667W (2/3W)
• Substitute parts: 0.75W (3/4W) or higher (equal or greater power rating acceptable)

Compliance & Certifications:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level MSL 1 (required)
• REACH Unaffected (required)

The identified substitute parts meet all critical electrical and mechanical parameters while maintaining or exceeding power rating specifications. Both substitute parts include automotive AEC-Q200 qualification, which represents an additional reliability certification beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Criteria:

All identified substitute parts (CRCW2010243RFKEF and RMCF2010FT243R) satisfy the core electrical and mechanical requirements for direct replacement of the RC5025F2430CS. The substitution is valid based on:

1. Electrical Equivalence: Identical resistance value (243 Ohms), tolerance (±1%), and temperature coefficient (±100ppm/°C)
2. Mechanical Compatibility: Identical 2010 (5025 Metric) package footprint and thick film composition
3. Power Rating: Substitute parts rated at 0.75W (3/4W) exceed the original 0.667W (2/3W) specification, providing margin for thermal performance
4. Regulatory Compliance: All parts maintain ROHS3 compliance, MSL 1 classification, and REACH Unaffected status
5. Product Status: All parts classified as Active, ensuring ongoing availability and support

Substitute Part Distinctions:

• CRCW2010243RFKEF (Vishay Dale): Includes automotive AEC-Q200 qualification; available in Tape & Reel packaging; 5088 units in stock
• RMCF2010FT243R (Stackpole Electronics): Includes automotive AEC-Q200 qualification; available in Tape & Reel packaging; 8927 units in stock

Both substitute parts carry identical electrical specifications and automotive-grade certifications. Selection between them is determined by supply chain availability, packaging requirements, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010243RFKEF or RMCF2010FT243R be used as direct replacements for RC5025F2430CS?

A: Yes. Both parts meet all critical electrical parameters (243 Ohms ±1%, ±100ppm/°C temperature coefficient) and mechanical requirements (2010 package, thick film composition). The substitute parts are rated at 0.75W, which exceeds the original 0.667W specification. All regulatory certifications (ROHS3, MSL 1, REACH Unaffected) are maintained.

Q: What is the difference in power rating between the original and substitute parts?

A: The RC5025F2430CS is rated at 0.667W (2/3W), while both substitute parts are rated at 0.75W (3/4W). The higher power rating of the substitutes provides additional thermal margin and does not create compatibility issues in applications designed for the original part.

Q: Are there any height differences that could affect PCB assembly?

A: The original part has a maximum seated height of 0.026" (0.66mm), while substitute parts have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is negligible for standard PCB assembly processes and does not affect component placement or clearance in typical applications.

Q: Do the substitute parts have additional certifications?

A: Yes. Both CRCW2010243RFKEF and RMCF2010FT243R include automotive AEC-Q200 qualification, which is an additional reliability standard beyond the base requirements of the original RC5025F2430CS. This certification is beneficial for applications requiring enhanced reliability assurance.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly processes. The original part packaging format is not specified in the provided data.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All three parts (RC5025F2430CS, CRCW2010243RFKEF, and RMCF2010FT243R) are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), meeting current environmental and regulatory requirements.
