RC5025F110CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F110CS is an 11 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) package. This component is classified as Active product status with moisture resistant characteristics and ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's functional requirements, enabling direct replacement in circuit designs where the original part becomes unavailable or inventory constraints necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F110CS are qualified based on the following criteria:

Electrical Parameters (Mandatory Match):

• Resistance value: 11 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Mandatory Match):

• Package type: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Composition: Thick Film
• Number of terminations: 2

Power Rating Consideration: Substitute parts may exceed the original 0.667W rating (up to 0.75W) without compromising compatibility, as higher power ratings provide equal or superior thermal performance in the same package footprint.

Compliance Parameters (Maintained):

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

Engineering Selection Recommendations

CRCW201011R0FKEF (Vishay Dale) is the primary substitute for the RC5025F110CS. This part maintains all electrical and mechanical compatibility parameters while offering increased power rating (0.75W versus 0.667W) in the identical 2010 package footprint. The CRCW201011R0FKEF carries Active product status and includes automotive AEC-Q200 qualification, providing enhanced reliability documentation. RoHS3 compliance and MSL 1 rating are maintained.

ERJ-12SF11R0U (Panasonic Electronic Components) is a secondary substitute option. While electrically and mechanically equivalent to the RC5025F110CS, this part carries "Not For New Designs" product status, indicating it is suitable for legacy system maintenance and repair applications only. The ERJ-12SF11R0U also includes AEC-Q200 automotive qualification and maintains all compliance requirements. Selection of this part should be limited to replacement scenarios where existing inventory or design continuity is the primary driver.

For new circuit designs, CRCW201011R0FKEF is the recommended substitute due to its Active product status and superior long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can CRCW201011R0FKEF replace RC5025F110CS in existing designs?

A: Yes. The CRCW201011R0FKEF is electrically and mechanically compatible with the RC5025F110CS. Both parts share identical resistance (11 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2010 package dimensions (5.00mm x 2.50mm). The higher power rating (0.75W versus 0.667W) of the CRCW201011R0FKEF does not create compatibility issues and provides thermal margin.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: Both ratings are valid for the 2010 package form factor. The 0.75W rating of substitute parts indicates higher thermal dissipation capability within the same physical dimensions. In circuit applications, the 0.667W-rated RC5025F110CS and 0.75W-rated substitutes are interchangeable; the higher rating of the substitute provides additional thermal headroom without affecting electrical performance.

Q: Why is ERJ-12SF11R0U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and long-term production commitment for this part. While the ERJ-12SF11R0U remains functionally equivalent and suitable for repair or legacy system applications, it should not be selected for new circuit designs where long-term component availability is a requirement. CRCW201011R0FKEF is the recommended choice for new designs.

Q: Are there height differences between these parts?

A: Minor height variations exist. The RC5025F110CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts (CRCW201011R0FKEF and ERJ-12SF11R0U) have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is negligible for standard PCB assembly and does not affect mechanical compatibility or board-level clearance in typical applications.

Q: Do all three parts maintain the same compliance certifications?

A: Yes. The RC5025F110CS, CRCW201011R0FKEF, and ERJ-12SF11R0U all carry ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status. Additionally, both substitute parts include AEC-Q200 automotive qualification, which the main part does not specify. This additional qualification does not create incompatibility and may provide enhanced reliability documentation for applications requiring automotive-grade components.
