RC5025F11R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F11R5CS is a 11.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor. The primary substitute listed is the ERJ-12SF11R5U from Panasonic Electronic Components, which shares identical resistance, tolerance, and package dimensions while offering increased power rating and automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F11R5CS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 11.5 Ohms
• Tolerance: ±1%
• Package form factor: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.667W
• Height - Seated: Within manufacturing tolerance
• Packaging format: May differ (bulk, tape & reel, etc.)
• Product status: May vary
• Certifications and ratings: May include additional qualifications

The ERJ-12SF11R5U from Panasonic meets all mandatory matching parameters while providing a higher power rating of 0.75W (3/4W) and automotive AEC-Q200 qualification, making it a valid electrical and mechanical substitute.

Engineering Selection Recommendations

RC5025F11R5CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures ongoing manufacturer support and availability
• Suitable for general industrial and commercial applications
• ROHS3 compliant with unlimited moisture sensitivity rating
• 1154 units in current inventory

ERJ-12SF11R5U (Panasonic Electronic Components) - Substitute Selection:

• Provides identical electrical performance with 12.5% higher power rating margin (0.75W vs 0.667W)
• AEC-Q200 automotive qualification enables use in automotive-grade applications
• ROHS3 compliant with unlimited moisture sensitivity rating
• Product status is "Not For New Designs," indicating this part is in mature/legacy phase
• 7580 units in current inventory
• Suitable for applications requiring automotive-grade reliability or higher thermal margin

Selection between these parts depends on application requirements. The RC5025F11R5CS is recommended for new designs requiring active product support. The ERJ-12SF11R5U is suitable for applications where automotive qualification or higher power dissipation capability is required, with the understanding that it is not recommended for new design initiation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF11R5U replace RC5025F11R5CS in existing designs?

A: Yes. The ERJ-12SF11R5U meets all mandatory electrical and mechanical parameters. The higher power rating (0.75W vs 0.667W) and identical package dimensions ensure direct substitution. The 0.002" (0.04mm) difference in seated height is within standard manufacturing tolerance for 2010 package components.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF11R5U?

A: This designation indicates the part is in mature production phase and Panasonic does not recommend its use in new product designs. However, it remains fully functional and available for replacement, repair, and legacy system applications. Existing designs using this part may continue to source it.

Q: Are there differences in thermal performance between these parts?

A: Both parts share identical temperature coefficient (±100ppm/°C) and operating range (-55°C to 155°C). The ERJ-12SF11R5U has a 12.5% higher power rating, which provides additional thermal margin in applications approaching the RC5025F11R5CS power limit.

Q: Do packaging format differences affect substitution?

A: The RC5025F11R5CS is supplied in standard packaging format, while the ERJ-12SF11R5U is supplied in Tape & Reel (TR) format. Both are compatible with standard pick-and-place assembly equipment. Format selection depends on production volume and assembly process requirements.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030. Both maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the basis for substitution between these specific parts?

A: Substitution is based on identical resistance (11.5 Ohms), tolerance (±1%), composition (thick film), package form (2010/5025 Metric), physical dimensions, temperature characteristics, and operating range. The ERJ-12SF11R5U additionally qualifies through higher power rating and automotive certification, both of which are compatible with or exceed the original specification.
