Parameter Comparison

Engineering Selection Recommendations

The SFS44T35-5K384E-F serves as the direct electrical equivalent for the obsolete SFS44S35-5K475E-F. Both components are manufactured by Cornell Dubilier Electronics within the SF series and maintain identical electrical specifications across capacitance, voltage rating, tolerance, and dielectric composition.

Product Status Consideration: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Status: Both components satisfy ROHS3 compliance requirements, supporting regulatory requirements for new designs and system upgrades.

Physical Dimensions: The substitute part exhibits different physical dimensions. The SFS44T35-5K384E-F has a larger diameter (2.620" versus 2.120") but reduced height (3.960" versus 4.870"). Mechanical fit within the application enclosure and mounting bracket must be evaluated based on specific installation geometry.

Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics identical between SFS44S35-5K475E-F and SFS44T35-5K384E-F?

A: Yes. Both components provide identical capacitance values (5µF and 35µF), voltage rating (440 V), tolerance (±10%), and dielectric material (Polypropylene Film, Metallized). Electrical substitution is direct.

Q: What is the primary reason for substitution?

A: The SFS44S35-5K475E-F is classified as obsolete. The SFS44T35-5K384E-F is an active product from the same manufacturer and series, providing equivalent electrical performance with assured ongoing availability.

Q: Do the physical dimensions affect substitution compatibility?

A: Physical dimensions differ between the two parts. The substitute is larger in diameter (2.620" versus 2.120") but shorter in height (3.960" versus 4.870"). Mechanical fit within the application enclosure and mounting bracket assembly must be verified for the specific installation.

Q: Are both parts RoHS compliant?

A: Yes. Both SFS44S35-5K475E-F and SFS44T35-5K384E-F are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: Can SFS44T35-5K384E-F be used in existing equipment designed for SFS44S35-5K475E-F?

A: Electrical substitution is valid. Mechanical compatibility depends on available space within the equipment enclosure and mounting bracket configuration. Physical dimensions must be confirmed against installation constraints before implementation.

Q: What mounting configuration is required for both parts?

A: Both components are chassis mount types requiring a holder or bracket. The mounting interface is identical; however, bracket dimensions may require adjustment based on the physical size differences of the substitute part.
