RC5025F5231CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F5231CS is a 5.23 kOhms ±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).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and critical performance parameters. Alternative sources become necessary for supply chain optimization, inventory availability, or application-specific certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5231CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 5.23 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

Allowable Variation:

• Power rating: Substitute parts may exceed the original 0.667W specification, provided the package dimensions remain within the 2010 footprint constraints and do not introduce thermal or mechanical incompatibilities in the target application.

The RMCF2010FT5K23 from Stackpole Electronics Inc meets all mandatory parameters while providing an increased power rating of 0.75W (3/4W) within the identical package footprint.

Parameter Comparison

Engineering Selection Recommendations

RC5025F5231CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring the specified 0.667W power rating
• ROHS3 compliant and MSL 1 rated for standard industrial and consumer applications
• Active product status ensures continued availability and supply chain stability

RMCF2010FT5K23 (Stackpole Electronics Inc):

• Direct substitute with increased power rating of 0.75W within identical 2010 package footprint
• AEC-Q200 automotive qualification provides additional reliability assurance for automotive-grade applications
• ROHS3 compliant and MSL 1 rated, maintaining environmental and compliance equivalence
• Identical electrical parameters (5.23 kOhms ±1%, ±100ppm/°C, -55°C to 155°C) ensure functional interchangeability
• Marginal height increase (0.028" vs 0.026") remains within standard PCB assembly tolerances for 2010 package format

Both parts are Active status with equivalent compliance certifications. Selection between these parts depends on application power dissipation requirements and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT5K23 replace RC5025F5231CS in all applications?

A: The RMCF2010FT5K23 is electrically and mechanically compatible with the RC5025F5231CS. The substitute part maintains identical resistance value (5.23 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The increased power rating (0.75W vs 0.667W) and marginal height difference (0.028" vs 0.026") do not introduce incompatibility within standard 2010 package assembly specifications. Verification of application-specific thermal and mechanical constraints is the responsibility of the design engineer.

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

A: The primary differences are manufacturer source and power rating. The RC5025F5231CS is rated for 0.667W, while the RMCF2010FT5K23 is rated for 0.75W. The Stackpole part includes AEC-Q200 automotive qualification. All other electrical, mechanical, and compliance parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC5025F5231CS and RMCF2010FT5K23 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: What is the significance of the 2010 package format?

A: The 2010 (5025 Metric) package format specifies the physical footprint dimensions of 5.00mm length by 2.50mm width. Both parts conform to this standard, ensuring PCB layout and assembly compatibility. Height variations (0.026" vs 0.028") remain within acceptable tolerances for this package class.

Q: Can I use the higher power-rated RMCF2010FT5K23 in place of the RC5025F5231CS?

A: Yes. A substitute part with higher power rating does not create functional or thermal incompatibility. The application will operate within the lower power dissipation envelope of the original specification. No design modification is required.

Q: What does ±100ppm/°C temperature coefficient mean?

A: The temperature coefficient specifies the resistance value change per degree Celsius across the operating temperature range. ±100ppm/°C indicates that the resistance value will vary by a maximum of 100 parts per million for each degree of temperature change. Both parts share this specification.

Q: Are there any packaging differences between these parts?

A: The RC5025F5231CS is specified with standard packaging notation (-), while the RMCF2010FT5K23 is supplied in Tape & Reel (TR) format. This affects procurement and assembly handling but does not alter electrical or mechanical compatibility.
