Key Parameters

Substitute Part Grouping Explanation

Substitution of the 32FB44075-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 7.5 µF
• Tolerance: ±10%
• Voltage rating (AC): 440V
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

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

Environmental Parameters:

• Operating temperature range: -40°C to 70°C
• RoHS3 compliance

Substitute parts must satisfy all electrical and mechanical parameters listed above. Physical dimensions (length, width, height) may vary within the constraints of the radial can package format, provided the component fits within the mechanical envelope of the original application and maintains the specified lead spacing.

Parameter Comparison

Engineering Selection Recommendations

The 32FB44075A-F is a direct electrical and mechanical equivalent to the 32FB44075-F. Both components are manufactured by Cornell Dubilier Electronics within the MPF series and satisfy identical electrical specifications: 7.5 µF capacitance at ±10% tolerance, 440V AC rating, and polypropylene metallized dielectric construction.

The primary distinction between these parts is product status: the 32FB44075-F is obsolete, while the 32FB44075A-F is active. The 32FB44075A-F is therefore the recommended selection for new designs, maintenance replacements, and ongoing supply requirements.

Physical dimension differences exist between the two parts. The 32FB44075A-F has a maximum seated height of 3.130" (79.50mm) compared to 2.880" (73.15mm) for the 32FB44075-F. Both maintain identical lead spacing of 0.813" (20.64mm) and radial can package configuration. Mechanical fit verification within the application enclosure is required prior to installation.

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

Frequently Asked Questions (FAQ)

Q: Can the 32FB44075A-F be used as a direct replacement for the 32FB44075-F?

A: Yes. The 32FB44075A-F is electrically and mechanically equivalent. Both components have identical capacitance (7.5 µF), tolerance (±10%), voltage rating (440V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C to 70°C), mounting type, package type, termination style, and lead spacing (0.813"). The primary difference is product status: 32FB44075-F is obsolete; 32FB44075A-F is active.

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

A: The 32FB44075A-F has a maximum seated height of 3.130" (79.50mm) versus 2.880" (73.15mm) for the 32FB44075-F. This 0.250" (6.35mm) difference must be evaluated against the mechanical constraints of the application enclosure. Lead spacing remains constant at 0.813" (20.64mm), ensuring electrical connection compatibility. Physical fit verification is required before installation.

Q: Are both parts suitable for motor run and power factor correction applications?

A: Yes. Both the 32FB44075-F and 32FB44075A-F are rated for motor run and power factor correction (PFC) applications. Electrical specifications, operating temperature range, and dielectric material are identical across both components.

Q: What is the packaging difference between these parts?

A: The 32FB44075-F is supplied in standard packaging, while the 32FB44075A-F is supplied in bulk packaging. This distinction affects procurement and inventory management but does not alter electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 32FB44075-F and 32FB44075A-F are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the 32FB44075-F classified as obsolete?

A: The 32FB44075-F is no longer in active production. The 32FB44075A-F serves as the active equivalent within the MPF series. For new designs and ongoing supply requirements, the 32FB44075A-F is the recommended selection.
