RC5025F5113CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F5113CS is a 511 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the 2010 package footprint, allowing for direct board-level replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5113CS is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance value: 511 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Allowable Variation:

• Power rating may be equal to or greater than 0.667W (substitute parts rated at 0.75W are acceptable as they provide equivalent or superior power dissipation capability within the same package footprint)

The identified substitute parts CRCW2010511KFKEF and ERJ-12SF5113U meet all mandatory parameters. Both maintain identical resistance, tolerance, package dimensions, and environmental specifications while providing increased power rating (0.75W) within the same 2010 package envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW2010511KFKEF (Vishay Dale)

The CRCW2010511KFKEF is the preferred substitute for the RC5025F5113CS. Both components maintain Active product status, ensuring continued manufacturer support and availability. The Vishay Dale part provides identical electrical specifications (511 kOhms ±1%, ±100ppm/°C) and mechanical compatibility within the 2010 package footprint. The increased power rating (0.75W versus 0.667W) presents no compatibility risk and provides additional thermal margin. AEC-Q200 automotive qualification of the CRCW2010511KFKEF extends application scope beyond the original part's specification.

Secondary Substitute: ERJ-12SF5113U (Panasonic Electronic Components)

The ERJ-12SF5113U meets all mandatory electrical and mechanical parameters with identical resistance, tolerance, temperature coefficient, and operating temperature range. However, this part carries "Not For New Designs" product status, indicating Panasonic has discontinued active development and support. The ERJ-12SF5113U is suitable only for legacy system maintenance or replacement applications where existing design validation has already been completed. New design implementations should prioritize the CRCW2010511KFKEF.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2010511KFKEF replace the RC5025F5113CS in existing designs?

A: Yes. The CRCW2010511KFKEF provides identical electrical specifications (511 kOhms ±1%, ±100ppm/°C) and maintains the same 2010 package footprint. The increased power rating (0.75W) is compatible with all applications designed for the original 0.667W part. Physical dimensions remain equivalent within specified tolerances.

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

A: The RC5025F5113CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts are rated at 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect board-level compatibility or clearance in standard 2010 package applications.

Q: Why is the ERJ-12SF5113U marked "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic has transitioned this part to end-of-life status and is no longer actively supporting new product development with this component. While the part remains functionally equivalent and suitable for legacy system support, new designs should specify the CRCW2010511KFKEF to ensure long-term availability and manufacturer support.

Q: Are the substitute parts AEC-Q200 qualified?

A: Yes. Both CRCW2010511KFKEF and ERJ-12SF5113U carry AEC-Q200 automotive qualification. The original RC5025F5113CS does not specify automotive qualification. Applications requiring AEC-Q200 compliance should select either substitute part.

Q: What is the impact of the power rating increase from 0.667W to 0.75W?

A: The higher power rating of the substitute parts indicates improved thermal performance and greater power dissipation capability within the same package envelope. This change is unidirectional compatible—a part rated for higher power can safely replace a lower-rated part in any application. No circuit redesign or thermal analysis modification is required.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC5025F5113CS, CRCW2010511KFKEF, and ERJ-12SF5113U are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with modern manufacturing processes and environmental regulations.
