RC5025F6492CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F6492CS is a 64.9 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 is classified as Active product status with moisture resistant characteristics and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor. The RC5025F6492CS serves as a reference baseline for locating functionally compatible alternatives from other manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the RC5025F6492CS are identified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 64.9 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package form factor: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (required for regulatory compatibility)

Secondary Consideration:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher satisfy applications requiring 0.667W (2/3W) due to derating capability
• Packaging format: Tape & Reel (TR) packaging is compatible with applications originally specified for standard packaging

The identified substitutes maintain all critical electrical parameters while offering equal or superior power handling capability within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

CRCW201064K9FKEF (Vishay Dale) is the primary substitute for new designs. This part maintains all electrical specifications of the RC5025F6492CS while providing increased power rating (0.75W versus 0.667W). The component carries Active product status, ensuring continued availability and manufacturing support. Automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications. Tape & Reel packaging format supports automated assembly processes.

ERJ-12SF6492U (Panasonic Electronic Components) is functionally equivalent but carries Not For New Designs product status. This designation indicates the manufacturer is discontinuing active development and support for this part number. While electrically and mechanically compatible, this substitute should be reserved for legacy system maintenance or applications where existing supply chains are established. Automotive AEC-Q200 qualification is maintained.

For applications requiring the RC5025F6492CS, CRCW201064K9FKEF is the recommended substitute due to Active product status and superior long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can CRCW201064K9FKEF replace RC5025F6492CS in existing designs?

A: Yes. Both parts share identical resistance value (64.9 kOhms), tolerance (±1%), package form factor (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The CRCW201064K9FKEF provides higher power rating (0.75W versus 0.667W), making it suitable for direct substitution with no circuit modifications required.

Q: What is the difference between 2/3W and 3/4W power ratings?

A: The RC5025F6492CS is rated for 0.667W continuous power dissipation, while CRCW201064K9FKEF and ERJ-12SF6492U are rated for 0.75W. The higher rating in substitute parts provides additional thermal margin and derating capability. In applications where the original part dissipates less than 0.667W, the substitute parts operate with increased safety margin.

Q: Why is ERJ-12SF6492U marked "Not For New Designs"?

A: This product status indicates Panasonic has transitioned this part number to end-of-life status. While currently in stock and functionally equivalent, the manufacturer is not actively supporting new design implementations. For new product development, CRCW201064K9FKEF is the recommended alternative.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F6492CS, CRCW201064K9FKEF, and ERJ-12SF6492U all carry ROHS3 Compliant status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly. Standard warehouse conditions are acceptable without desiccant packaging or controlled humidity environments.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, with packaging format consideration. RC5025F6492CS is supplied in standard packaging, while CRCW201064K9FKEF and ERJ-12SF6492U are supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly equipment. Both formats are compatible with standard surface mount assembly processes.
