RC5025F515CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F515CS is a 5.1 MOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). This resistor is designed for general-purpose applications requiring high resistance values with tight tolerance specifications. Equivalent and substitute parts are identified to provide procurement flexibility, ensure supply chain continuity, and support design requirements where alternative sourcing is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F515CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 5.1 MOhms (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 to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power dissipation ratings
• Manufacturer: Different manufacturers permitted
• Packaging Format: Different packaging formats (e.g., Tape & Reel vs. bulk) permitted
• Additional Features: Substitute parts may include additional certifications or features (e.g., AEC-Q200 automotive qualification)

The RMCF2010FT5M10 from Stackpole Electronics Inc qualifies as a substitute because it maintains all mandatory matching parameters while offering a higher power rating (0.75W vs. 0.667W) and includes automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT5M10 from Stackpole Electronics Inc is a qualified substitute for the RC5025F515CS based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance value (5.1 MOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute's higher power rating (0.75W vs. 0.667W) provides additional thermal margin and does not create incompatibility.

Mechanical Compatibility: Both parts use the 2010 (5025 Metric) package with matching footprint dimensions (0.197" L x 0.098" W). The seated height difference (0.028" vs. 0.026") is within acceptable PCB assembly tolerances and does not affect board-level compatibility.

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0030) codes. Both maintain MSL 1 (unlimited) moisture sensitivity level.

Product Status: Both parts are classified as Active products with established supply availability. The substitute includes automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Selection between these parts should be based on procurement availability, cost considerations, and application-specific requirements for automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2010FT5M10 be used as a direct replacement for the RC5025F515CS in existing designs?

A: Yes. Both parts share identical electrical specifications (5.1 MOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical package (2010/5025 Metric). The substitute's higher power rating (0.75W vs. 0.667W) and automotive AEC-Q200 certification do not create incompatibility. PCB footprints and assembly processes remain unchanged.

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

A: The RC5025F515CS is rated for 0.667W (2/3W) dissipation, while the RMCF2010FT5M10 is rated for 0.75W (3/4W). The substitute's higher rating provides additional thermal headroom. In applications where the original part operates near its power limit, the substitute offers improved reliability margins. No circuit redesign is required.

Q: Are there packaging format differences between these parts?

A: The RC5025F515CS is supplied in standard packaging, while the RMCF2010FT5M10 is supplied in Tape & Reel (TR) format. Both formats are compatible with automated assembly equipment. Selection depends on procurement volume and assembly process requirements.

Q: Does the RMCF2010FT5M10's AEC-Q200 certification affect its use in non-automotive applications?

A: No. AEC-Q200 certification indicates the part meets automotive reliability standards and is suitable for automotive environments. This certification does not restrict use in general-purpose or non-automotive applications. The part remains fully compatible with any application requiring the specified electrical and mechanical parameters.

Q: What is the impact of the 0.002" (0.04mm) seated height difference?

A: The height difference (0.028" vs. 0.026") is negligible for PCB assembly. Standard PCB design tolerances and component placement equipment accommodate this variation without requiring design modifications or assembly process changes.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC5025F515CS and RMCF2010FT5M10 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can these parts be intermixed in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent within the specified parameters. They can be used interchangeably in the same design and production environment without requiring separate qualification or testing procedures.
