RC5025F5621CS Equivalent & Substitute Parts

Part Overview

The RC5025F5621CS is a 5.62 kOhm ±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 features moisture-resistant construction with an operating temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating.

Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, and power rating) and mechanical compatibility (package dimensions and termination count). Alternative sources provide equivalent performance for applications where the primary part is unavailable or where design requirements permit higher power ratings within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5621CS is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 5.62 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Number of Terminations: 2
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as they provide equal or greater power dissipation capability within the same package envelope, ensuring thermal compatibility and mechanical fit.

Compliance Requirements:

• RoHS3 compliance required
• MSL 1 rating required
• REACH Unaffected status required

The identified substitute parts meet all mandatory criteria and allowable variations. Both CRCW20105K62FKEF and ERJ-12SF5621U maintain identical electrical performance and mechanical compatibility while offering enhanced power handling capacity.

Parameter Comparison

Engineering Selection Recommendations

CRCW20105K62FKEF (Vishay Dale) is the primary substitute for the RC5025F5621CS. This part maintains active product status and is rated for automotive applications under AEC-Q200 qualification. The 0.75W power rating provides enhanced thermal margin within the identical 2010 package footprint. All compliance requirements including ROHS3, MSL 1, and REACH Unaffected status are met. This part is suitable for new designs and production applications.

ERJ-12SF5621U (Panasonic Electronic Components) is a secondary substitute option. While electrically and mechanically equivalent to the primary substitute, this part carries a "Not For New Designs" product status designation. The part remains available in inventory and maintains full compliance with ROHS3, MSL 1, and REACH requirements. This part is appropriate for legacy system support, maintenance, and repair applications where design freeze conditions apply.

Selection between the primary and secondary substitute should be based on design phase requirements and long-term supply chain planning. Active product status of CRCW20105K62FKEF ensures continued availability and manufacturing support for ongoing production.

Frequently Asked Questions (FAQ)

Q: Can CRCW20105K62FKEF be used as a direct replacement for RC5025F5621CS?

A: Yes. Both parts share identical resistance (5.62 kOhms), tolerance (±1%), package (2010), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW20105K62FKEF is rated for 0.75W compared to the RC5025F5621CS at 0.667W, providing equivalent or superior performance in the same footprint.

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

A: The 0.75W rating of substitute parts provides additional thermal dissipation capacity. In applications where the RC5025F5621CS operates at or near its 0.667W limit, the substitute parts offer improved thermal margin and reliability. Both ratings are compatible with identical circuit board layouts and thermal management designs.

Q: Are there height differences between the main part and substitutes?

A: The RC5025F5621CS 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 mechanical compatibility or board-level integration.

Q: Why is ERJ-12SF5621U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy support only. While the part remains available and fully functional, new product designs should prioritize CRCW20105K62FKEF, which carries active product status and ensures long-term supply chain continuity.

Q: Are all three parts ROHS3 compliant?

A: Yes. The RC5025F5621CS, CRCW20105K62FKEF, and ERJ-12SF5621U are all ROHS3 compliant with MSL 1 rating and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for the substitute parts?

A: Both CRCW20105K62FKEF and ERJ-12SF5621U are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The RC5025F5621CS is available with standard packaging designation.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW20105K62FKEF carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. ERJ-12SF5621U also carries AEC-Q200 qualification but with "Not For New Designs" status. The RC5025F5621CS does not specify automotive qualification in the provided parameters.
