Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFS44S25-7.5K400E-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance values: 7.5µF and 25µF
• Voltage rating: 440 V
• Tolerance: ±10%
• Number of capacitors: 2
• Circuit configuration: Bussed

Physical & Mechanical Parameters:

• Dielectric material: Polypropylene (PP) Film, Metallized
• Mounting type: Chassis Mount, Requires Holder/Bracket
• Package type: Radial, Can

Compliance & Status:

• RoHS3 Compliance required
• REACH Unaffected status required
• Active product status preferred for long-term availability

Substitute parts must maintain identical electrical specifications and dielectric composition. Physical dimensions may vary within the constraints of the radial can package format, provided the component remains compatible with standard chassis mount holder/bracket systems.

Parameter Comparison

Engineering Selection Recommendations

The SFS44T25-7.5K384E-F is a direct electrical and functional equivalent to the SFS44S25-7.5K400E-F. Both components share identical capacitance values, voltage ratings, tolerance specifications, and dielectric composition. The substitute part maintains full compliance with RoHS3 and REACH requirements.

The primary distinction between the two parts is product status: the SFS44S25-7.5K400E-F is classified as obsolete, while the SFS44T25-7.5K384E-F is active. This status difference ensures continued availability and supply chain support for the substitute part.

Physical dimensions differ between the two models. The substitute part (SFS44T25-7.5K384E-F) has a larger diameter (2.620" versus 2.120") but a slightly reduced height (3.960" versus 4.120"). Both components are designed for chassis mount applications with holder/bracket systems. Dimensional compatibility with existing mounting hardware must be verified for the specific application.

Selection of the SFS44T25-7.5K384E-F is appropriate for applications requiring active product status, long-term availability, and equivalent electrical performance.
