Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F203CS are qualified based on the following critical parameters:

Electrical Equivalence:

• Resistance value: 20 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

• Package type: 2010 (5025 Metric) (exact match required)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

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

The identified substitute parts meet all electrical and mechanical requirements. Power rating variations (0.75W vs. 0.667W) represent increased capability and are acceptable in substitution scenarios where the original power rating is sufficient for the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—CRCW201020K0FKEF (Vishay Dale) and RMCF2010FT20K0 (Stackpole Electronics Inc)—are qualified equivalents for the RC5025F203CS based on electrical and mechanical parameter alignment.

CRCW201020K0FKEF (Vishay Dale):

• Meets all electrical specifications with identical resistance, tolerance, and temperature coefficient
• Maintains 2010 package compatibility with identical footprint dimensions
• Rated for 0.75W, providing increased power handling margin
• AEC-Q200 automotive qualification available
• ROHS3 and REACH compliant
• Active product status with established supply chain

RMCF2010FT20K0 (Stackpole Electronics Inc):

• Meets all electrical specifications with identical resistance, tolerance, and temperature coefficient
• Maintains 2010 package compatibility with identical footprint dimensions
• Rated for 0.75W, providing increased power handling margin
• AEC-Q200 automotive qualification available
• ROHS3 and REACH compliant
• Active product status with high inventory availability (23,952 Pcs)

Both substitutes are suitable for direct replacement in applications where the original RC5025F203CS component is specified. Selection between substitutes may be based on supply chain availability, lead time, or established vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can CRCW201020K0FKEF or RMCF2010FT20K0 be used as direct replacements for RC5025F203CS?

A: Yes. Both parts meet the critical electrical parameters (20 kOhms ±1%, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and mechanical requirements (2010 package, 5.00mm x 2.50mm dimensions, thick film composition). All three components are ROHS3 compliant with MSL 1 rating and REACH Unaffected status.

Q: What is the difference in power rating between the main part and substitutes?

A: The RC5025F203CS is rated at 0.667W (2/3W), while CRCW201020K0FKEF and RMCF2010FT20K0 are rated at 0.75W (3/4W). The higher power rating of the substitutes represents increased thermal capability and does not affect compatibility in applications where 0.667W is the design requirement.

Q: Are there height differences between these parts?

A: The RC5025F203CS has a maximum seated height of 0.026" (0.66mm), while both substitutes have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect board-level compatibility.

Q: Do the substitute parts have automotive qualification?

A: Both CRCW201020K0FKEF and RMCF2010FT20K0 carry AEC-Q200 automotive qualification. The RC5025F203CS does not list this certification in the provided specifications.

Q: What is the packaging format for these parts?

A: The RC5025F203CS is supplied in standard packaging format. Both substitutes (CRCW201020K0FKEF and RMCF2010FT20K0) are supplied in Tape & Reel (TR) format, which is standard for high-volume SMD component distribution.

Q: Are all three parts currently in active production?

A: Yes. RC5025F203CS, CRCW201020K0FKEF, and RMCF2010FT20K0 all maintain Active product status, indicating ongoing manufacturing and availability through authorized distributors.
