RC5025F4643CS Equivalent & Substitute Parts

Part Overview

The RC5025F4643CS is a 464 kOhms ±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 and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements permit higher performance ratings within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025F4643CS is permissible when the following criteria are met:

Mandatory Matching Parameters:

• Resistance value: 464 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power dissipation ratings, provided physical dimensions remain compatible with the 2010 package specification.

The CRCW2010464KFKEF from Vishay Dale meets all mandatory parameters and provides an increased power rating of 0.75W (3/4W), making it a valid substitute for applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

RC5025F4643CS (Samsung Electro-Mechanics): Use as the primary component selection when available. This part is Active status with full ROHS3 compliance and unlimited moisture sensitivity rating. Suitable for general industrial and consumer applications requiring 464 kOhms ±1% resistance in the 2010 package format.

CRCW2010464KFKEF (Vishay Dale): Use as a direct substitute when RC5025F4643CS is unavailable. This part maintains identical electrical specifications and package dimensions while providing increased power dissipation capability (0.75W versus 0.667W). The CRCW2010464KFKEF carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. Both parts are Active status with ROHS3 compliance and unlimited moisture sensitivity. The marginal increase in seated height (0.028" versus 0.026") is within typical PCB assembly tolerances for 2010 package components.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010464KFKEF replace RC5025F4643CS in all applications?

A: Yes, within the scope of electrical and mechanical compatibility. The CRCW2010464KFKEF provides identical resistance value, tolerance, temperature coefficient, and operating temperature range. The increased power rating (0.75W versus 0.667W) is a performance enhancement that does not create incompatibility. Physical dimensions are equivalent within standard PCB assembly tolerances.

Q: What is the significance of the power rating difference?

A: The RC5025F4643CS is rated for 0.667W continuous dissipation, while the CRCW2010464KFKEF is rated for 0.75W. In applications where the original part operates below its power rating, the substitute part provides additional thermal margin. No derating or design modification is required when substituting to a higher power rating within the same package.

Q: Are there packaging differences between these parts?

A: The RC5025F4643CS is supplied in standard packaging format. The CRCW2010464KFKEF is supplied in Tape & Reel (TR) format. Both parts use identical 2010 (5025 Metric) package geometry. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC5025F4643CS and CRCW2010464KFKEF are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry unlimited moisture sensitivity rating (MSL 1). The CRCW2010464KFKEF additionally carries AEC-Q200 automotive qualification.

Q: What is the maximum seated height difference?

A: The RC5025F4643CS has a maximum seated height of 0.026" (0.66mm), while the CRCW2010464KFKEF has a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect component placement or board-level compatibility.
