Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 23FB4425-F are qualified based on the following critical parameters that determine functional equivalence:

Electrical Parameters:

• Capacitance value: 25 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating (AC): 440V (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C to 70°C (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination style: Quick Connect, Disconnect (exact match required)

Compliance Parameters:

• RoHS3 Compliance (required for modern applications)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria. Physical dimensions (diameter, height, lead spacing) may vary within acceptable tolerances for chassis-mounted applications, provided the component fits within the designated holder or bracket assembly.

Parameter Comparison

Engineering Selection Recommendations

23FB4425A-F (Primary Substitute): The 23FB4425A-F is the direct successor to the obsolete 23FB4425-F within the same MPF series. This part maintains identical electrical specifications, mounting requirements, and termination style. The component is currently in active production status, ensuring long-term availability and supply chain continuity. Physical dimensions are nearly identical to the main part, with a marginal reduction in seated height (3.160" versus 3.250"). This substitute is suitable for direct replacement in existing motor run and power factor correction applications without circuit modification.

SFS44T25K291B-F (Alternative Substitute): The SFS44T25K291B-F represents an alternative from the SF series with identical electrical performance and compliance certifications. This part exhibits reduced physical dimensions compared to the main part, with a seated height of 3.030" and a marginally smaller diameter of 2.120". Lead spacing remains within acceptable tolerance (0.810" versus 0.813"). This substitute is appropriate for applications where space constraints or holder/bracket compatibility require a more compact form factor. The part is in active production status and carries ROHS3 compliance.

Both substitute parts satisfy all critical electrical and mechanical parameters required for functional equivalence. Selection between them depends on physical space availability within the equipment chassis and holder/bracket assembly specifications.

Frequently Asked Questions (FAQ)

Q: Can the 23FB4425A-F be used as a direct replacement for the 23FB4425-F?

A: Yes. The 23FB4425A-F maintains identical capacitance (25 µF), tolerance (±10%), voltage rating (440V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C to 70°C), mounting type (chassis mount with holder/bracket), package type (radial can), and termination style (quick connect/disconnect). Physical dimensions are nearly equivalent, with the substitute featuring a slightly reduced seated height. No circuit modifications are required.

Q: What is the difference between the 23FB4425A-F and SFS44T25K291B-F substitutes?

A: Both parts satisfy identical electrical specifications and compliance requirements. The primary differences are series designation (MPF versus SF) and physical dimensions. The SFS44T25K291B-F is more compact, with a seated height of 3.030" compared to 3.160" for the 23FB4425A-F. Selection depends on available space within the equipment chassis and compatibility with the existing holder/bracket assembly.

Q: Are there any compatibility concerns with the reduced height of the SFS44T25K291B-F?

A: The SFS44T25K291B-F has a seated height of 3.030" compared to the original 23FB4425-F height of 3.250". This 0.220" reduction may affect fit within certain holder/bracket assemblies. Verify that the equipment's mechanical mounting structure accommodates the reduced height before selection. Lead spacing (0.810" versus 0.813") remains within acceptable tolerance for quick connect/disconnect terminations.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both the 23FB4425A-F and SFS44T25K291B-F are ROHS3 compliant, meeting current environmental and regulatory requirements for industrial applications.

Q: What is the lead time and availability for these substitute parts?

A: Availability information is provided in the inventory data. The 23FB4425A-F has 914 units in stock, and the SFS44T25K291B-F has 812 units in stock. Contact the supplier for current lead times and delivery schedules.

Q: Can these capacitors be used in both motor run and power factor correction applications?

A: The 23FB4425A-F is rated for both motor run and power factor correction (PFC) applications. The SFS44T25K291B-F is rated for motor run applications. Verify application requirements before selecting the SFS44T25K291B-F for power factor correction circuits.
