RC5025F2873CS Equivalent & Substitute Parts

Part Overview

The RC5025F2873CS is a 287 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) continuous power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status and carries ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when design requirements shift toward automotive-grade components, or when alternative sourcing strategies are implemented to optimize supply chain resilience and cost management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2873CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 287 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may exceed the 0.667W specification, provided the higher power rating does not introduce incompatibility with the circuit design or thermal management requirements.

The ERJ-12SF2873U from Panasonic Electronic Components meets all mandatory parameters while providing an increased power rating of 0.75W (3/4W), making it a valid electrical and mechanical substitute.

Engineering Selection Recommendations

RC5025F2873CS (Primary Selection): The RC5025F2873CS maintains Active product status and carries ROHS3 compliance certification, making it the preferred choice for new designs and applications requiring regulatory adherence to current environmental standards. This component is suitable for general-purpose applications where moisture resistance and standard thick film performance are required.

ERJ-12SF2873U (Conditional Substitute): The ERJ-12SF2873U is classified as Not For New Designs and carries RoHS non-compliant status. This part is suitable only for legacy system maintenance, field replacements in existing equipment, or applications where automotive-grade AEC-Q200 qualification is a specific requirement. The increased power rating of 0.75W provides additional thermal margin compared to the primary part. The marginal height difference (0.028" versus 0.026") remains within typical PCB assembly tolerances for 2010 package components.

Selection between these parts must be driven by product lifecycle stage, regulatory compliance requirements, and specific application demands rather than general substitution preference.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF2873U be used as a direct replacement for the RC5025F2873CS in new designs?

A: No. The ERJ-12SF2873U carries Not For New Designs status and RoHS non-compliant certification. New designs should utilize the RC5025F2873CS, which maintains Active status and ROHS3 compliance.

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

A: The RC5025F2873CS is rated for 0.667W while the ERJ-12SF2873U is rated for 0.75W. Both ratings are sufficient for circuits designed around the 287 kOhm resistance value. The higher power rating of the substitute part does not create incompatibility; it provides additional thermal headroom. Circuit design must ensure actual power dissipation does not exceed the lower rating of the primary part.

Q: Are there physical compatibility concerns between these two parts?

A: Both components use the 2010 (5025 Metric) package with identical length and width dimensions (0.197" x 0.098"). The seated height differs by 0.002" (0.04mm), which is negligible for standard PCB assembly processes and does not affect electrical performance or mechanical fit.

Q: What compliance certifications differ between these parts?

A: The RC5025F2873CS is ROHS3 compliant, while the ERJ-12SF2873U is RoHS non-compliant. Both parts are REACH Unaffected. The ERJ-12SF2873U carries AEC-Q200 automotive qualification, which the RC5025F2873CS does not specify.

Q: Under what circumstances would the ERJ-12SF2873U be an appropriate selection?

A: The ERJ-12SF2873U is appropriate for field replacements in legacy systems already deployed with this component, for maintenance of existing equipment, or for applications where automotive-grade AEC-Q200 qualification is a mandatory design requirement and RoHS compliance is not a constraint.

Q: Do these parts have identical electrical performance characteristics?

A: Yes. Both parts share identical resistance value (287 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Electrical performance is equivalent within the specified parameters.
