RC5025F4220CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F4220CS is a 422 Ohm ±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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 993 units currently in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package format, dimensions, termination count). Alternative sources become necessary for supply chain continuity, extended lead time mitigation, or when specific certifications such as automotive qualification are required for application requirements.

Substitute Part Grouping Explanation

Substitution logic for the RC5025F4220CS is based on the following criteria:

Electrical Equivalence Requirements:

• Resistance value: 422 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: minimum 0.667W (equal or higher acceptable)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (equal or wider acceptable)

Mechanical Compatibility Requirements:

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

Regulatory & Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

Identified substitute parts meet all electrical and mechanical criteria. Power ratings of substitute parts (0.75W / 3/4W) exceed the minimum requirement of 0.667W, providing thermal margin. Automotive AEC-Q200 certification is present in substitute parts but not required for general substitution compatibility.

Engineering Selection Recommendations

Primary Substitute: CRCW2010422RFKEF (Vishay Dale)

The CRCW2010422RFKEF is the preferred substitute for the RC5025F4220CS. This part maintains Active product status, ensuring continued availability and manufacturing support. All electrical parameters match the original specification, with power rating increased to 0.75W, providing additional thermal margin. The component carries AEC-Q200 automotive qualification, which extends application scope without compromising general-purpose use. RoHS3 compliance and MSL 1 rating align with the original part's regulatory and handling requirements.

Secondary Substitute: ERJ-12SF4220U (Panasonic Electronic Components)

The ERJ-12SF4220U meets all electrical and mechanical substitution criteria with identical resistance, tolerance, temperature coefficient, and operating temperature range. Power rating of 0.75W exceeds the minimum requirement. However, this part carries a "Not For New Designs" product status designation, indicating that Panasonic has discontinued active development and support for this component line. This part remains suitable for legacy system maintenance and repair applications where existing inventory is available, but should not be selected for new circuit designs or long-term production requirements.

Selection Criteria Summary:

• For new designs and active production: Select CRCW2010422RFKEF
• For legacy system support with existing inventory: ERJ-12SF4220U is acceptable
• All three parts are electrically and mechanically interchangeable within the specified parameters
• Height variation (0.66mm vs 0.70mm) is negligible for standard PCB assembly processes

Frequently Asked Questions (FAQ)

Q: Can CRCW2010422RFKEF directly replace RC5025F4220CS in existing designs?

A: Yes. Both parts share identical electrical specifications (422 Ohms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions, 2 terminations). The higher power rating (0.75W vs 0.667W) provides additional thermal capacity. Height difference of 0.04mm (0.70mm vs 0.66mm) is within standard PCB assembly tolerances.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF4220U?

A: This designation indicates that Panasonic has transitioned this product line to end-of-life status. While the part remains electrically and mechanically equivalent, the manufacturer no longer actively develops or guarantees long-term availability. This part should be used only for repair and maintenance of existing systems where inventory exists. New circuit designs should specify CRCW2010422RFKEF or RC5025F4220CS.

Q: Are there any thermal performance differences between the substitute parts?

A: The RC5025F4220CS is rated for 0.667W continuous dissipation, while both CRCW2010422RFKEF and ERJ-12SF4220U are rated for 0.75W. In applications operating near the original 0.667W limit, the substitute parts provide approximately 12% additional thermal margin. This difference does not affect electrical performance but may extend component life in thermally constrained environments.

Q: Do the substitute parts require different PCB layout considerations?

A: No. All three parts use the identical 2010 (5025 Metric) package format with matching pad dimensions and spacing. PCB footprints, trace routing, and assembly processes remain unchanged. The maximum height variation of 0.04mm is negligible for standard reflow soldering and component placement processes.

Q: Which substitute part should be selected for automotive applications?

A: CRCW2010422RFKEF carries AEC-Q200 automotive qualification, making it the appropriate choice for automotive circuit designs. ERJ-12SF4220U also carries AEC-Q200 certification but has "Not For New Designs" status. RC5025F4220CS does not list automotive certification. For automotive applications, CRCW2010422RFKEF is the recommended selection.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F4220CS, CRCW2010422RFKEF, and ERJ-12SF4220U all carry ROHS3 Compliant status. All parts are REACH Unaffected and classified under ECCN EAR99 for export purposes.

Q: What is the practical difference in moisture sensitivity between these parts?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. Standard storage conditions (room temperature, normal humidity) are acceptable. No special desiccant packaging or baking procedures are required prior to assembly.
