RC5025F2870CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2870CS is a 287 Ohm ±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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 1147 units currently in stock inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format, resistance value, tolerance, and operating temperature range. Alternative sources provide design flexibility, supply chain redundancy, and access to components with enhanced automotive qualification or higher power ratings within the same footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2870CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 287 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Allowable Variation:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or greater power dissipation capability within the same package footprint
• Packaging format: Original Tape & Reel (TR) packaging differs from the main part but does not affect electrical or mechanical compatibility

Identified Substitutes:

1. CRCW2010287RFKEF (Vishay Dale) – Meets all mandatory parameters with 0.75W power rating and AEC-Q200 automotive qualification
2. ERJ-12SF2870U (Panasonic Electronic Components) – Meets all mandatory parameters with 0.75W power rating and AEC-Q200 automotive qualification; marked as Not For New Designs

Engineering Selection Recommendations

Primary Substitute: CRCW2010287RFKEF (Vishay Dale)

The CRCW2010287RFKEF is the preferred substitute for new designs and ongoing production. This component maintains Active product status, meets all electrical and mechanical specifications of the RC5025F2870CS, and provides enhanced power rating (0.75W versus 0.667W) within the identical 2010 package footprint. AEC-Q200 automotive qualification provides additional reliability assurance for applications requiring automotive-grade components. Inventory availability is substantial at 8796 units.

Secondary Substitute: ERJ-12SF2870U (Panasonic Electronic Components)

The ERJ-12SF2870U meets all electrical and mechanical compatibility requirements and carries AEC-Q200 automotive qualification. However, this component is designated as Not For New Designs, indicating that Panasonic has discontinued active development and support for this product line. Use of this substitute is limited to legacy system maintenance, repair, or applications where existing design validation has already been completed. Inventory availability is 7089 units.

Height Consideration:

Both substitute parts exhibit a maximum seated height of 0.028" (0.70mm) compared to the main part's 0.026" (0.66mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect mechanical compatibility in standard surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010287RFKEF be used as a direct replacement for RC5025F2870CS in existing designs?

A: Yes. Both components share identical resistance (287 Ohms), tolerance (±1%), package format (2010/5025 Metric), composition (Thick Film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW2010287RFKEF provides higher power rating (0.75W versus 0.667W), which is compatible with all applications designed for the original part.

Q: What is the significance of the 0.002" height difference between the main part and substitutes?

A: The height difference (0.026" versus 0.028" maximum seated height) is negligible in standard PCB assembly processes. This variation falls within normal manufacturing tolerances and does not affect component placement, solder reflow profiles, or clearance requirements in typical circuit board designs.

Q: Why is ERJ-12SF2870U marked as "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this product line to end-of-life status and is no longer actively developing or supporting new applications. While the component remains functionally equivalent and is suitable for repair or legacy system maintenance, new product designs should prioritize the CRCW2010287RFKEF or the original RC5025F2870CS.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC5025F2870CS, CRCW2010287RFKEF, and ERJ-12SF2870U are all ROHS3 Compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What packaging formats are available for these substitutes?

A: The RC5025F2870CS is supplied in standard packaging format. Both CRCW2010287RFKEF and ERJ-12SF2870U are available in Tape & Reel (TR) format, which is standard for high-volume surface-mount production and automated assembly processes.

Q: Can these 287 Ohm resistors be used in automotive applications?

A: The CRCW2010287RFKEF and ERJ-12SF2870U carry AEC-Q200 automotive qualification, confirming suitability for automotive-grade applications. The RC5025F2870CS does not specify AEC-Q200 qualification; verification with Samsung Electro-Mechanics is required for automotive use.
