24FB4440-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The 24FB4440-F is a 40 µF film capacitor rated for 440V AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the MPF series. This component is designed for motor run and power factor correction (PFC) applications, featuring polypropylene metallized dielectric construction with radial can packaging and quick connect termination.

The 24FB4440-F is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and maintenance applications. Active equivalent models provide identical electrical performance with improved supply chain accessibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24FB4440-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 40 µF
• Tolerance: ±10%
• Voltage Rating (AC): 440V
• Dielectric Material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Package Type: Radial, Can
• Termination Style: Quick Connect, Disconnect
• Lead Spacing: 0.813" (20.64mm)

Environmental Parameters:

• Operating Temperature Range: -40°C to 70°C
• RoHS3 Compliance

Substitute parts must match all electrical and mechanical parameters. Dimensional variations in height are acceptable provided the component fits within the designated chassis mount holder/bracket assembly. Product status (active vs. obsolete) does not affect substitution eligibility but indicates supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The 24FB4440A-F is a direct electrical and mechanical equivalent to the 24FB4440-F. Both components are manufactured by Cornell Dubilier Electronics in the MPF series and share identical electrical specifications: 40 µF capacitance, ±10% tolerance, and 440V AC rating with polypropylene metallized dielectric construction.

The primary distinction is product status: the 24FB4440-F is obsolete, while the 24FB4440A-F is active. The 24FB4440A-F offers superior supply chain availability and is the preferred selection for new designs and replacement applications.

A dimensional difference exists in seated height: the 24FB4440-F measures 3.250" (82.55mm) maximum, while the 24FB4440A-F measures 4.160" (105.66mm) maximum. Both components maintain identical diameter (2.625" / 66.68mm) and lead spacing (0.813" / 20.64mm). Height variation is acceptable within standard chassis mount holder/bracket assemblies designed for radial can capacitors of this class.

Both parts are ROHS3 compliant and suitable for motor run and power factor correction applications across the -40°C to 70°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 24FB4440A-F replace the 24FB4440-F in existing equipment?

A: Yes. The 24FB4440A-F is electrically and mechanically equivalent. Both components have identical capacitance (40 µF), voltage rating (440V AC), tolerance (±10%), dielectric material (polypropylene metallized), mounting type (chassis mount with holder/bracket), termination style (quick connect/disconnect), and lead spacing (0.813"). The height difference (3.250" vs. 4.160") is accommodated within standard radial can capacitor mounting brackets.

Q: What is the significance of the height difference between these parts?

A: The 24FB4440A-F is 0.910" (23.11mm) taller than the 24FB4440-F. This dimension is non-critical for substitution because both components are designed for chassis mount installation with holder/bracket assemblies that accommodate standard radial can capacitor heights in this voltage and capacitance class. Verify available vertical clearance in the equipment enclosure before installation.

Q: Why is the 24FB4440-F listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 24FB4440A-F is the active equivalent and is the recommended selection for all new applications and replacements.

Q: Are there any compliance differences between these parts?

A: No. Both the 24FB4440-F and 24FB4440A-F are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level). Both are classified under ECCN EAR99 and HTSUS 8532.25.0020.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications. Operating temperature range is -40°C to 70°C for both components.

Q: Is packaging type a consideration for substitution?

A: The 24FB4440-F is packaged in standard format, while the 24FB4440A-F is packaged in bulk. Packaging does not affect electrical or mechanical performance. Select based on procurement quantity requirements.
