32FB44075A-F Film Capacitor 7.5µF 440VAC Equivalent & Substitute Parts

Part Overview

The 32FB44075A-F is a 7.5 µF film capacitor rated for 440V AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the MPF series. This radial, metallized polypropylene capacitor is designed for motor run and power factor correction (PFC) applications requiring chassis mount installation with a holder or bracket. The part is currently active in production with 1016 units in stock. Substitute parts are identified when the primary part becomes unavailable, when inventory levels require alternative sourcing, or when equivalent electrical and mechanical specifications are required for system continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (32FB44075A-F): The 32FB44075A-F remains the primary selection for new designs and standard procurement. This part carries active product status with higher inventory availability (1016 units). It is ROHS3 compliant and REACH unaffected, meeting all current regulatory requirements for motor run and PFC applications.

Substitute Part Selection (SFA44T7.5K288B-F): The SFA44T7.5K288B-F is a direct electrical and mechanical equivalent suitable for use when the primary part is unavailable or when inventory constraints require alternative sourcing. This part maintains identical electrical specifications, operating temperature range, and regulatory compliance. Physical dimensions are within acceptable tolerances for chassis-mounted applications. Both parts are manufactured by the same supplier, ensuring consistent quality and performance characteristics.

Interchangeability Basis: Both parts satisfy the complete set of electrical, mechanical, and environmental requirements for motor run and power factor correction applications operating at 440V AC. The dimensional variations between parts are negligible for chassis-mounted installations using standard holder/bracket assemblies. Selection between these parts may be based on inventory availability, lead time, or procurement preference without affecting circuit performance or system reliability.

Frequently Asked Questions (FAQ)

Q: Can the SFA44T7.5K288B-F be used as a direct replacement for the 32FB44075A-F in existing installations?

A: Yes. Both parts are electrically identical with 7.5 µF capacitance, ±10% tolerance, and 440V AC rating. Both use metallized polypropylene dielectric and operate across the same temperature range (-40°C to 70°C). Physical dimensions are within acceptable tolerances for chassis-mounted applications. No circuit modifications are required.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution requires identical capacitance (7.5 µF), tolerance (±10%), voltage rating (440V AC), and dielectric material (polypropylene, metallized). Any deviation in these parameters disqualifies a part from substitution.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 32FB44075A-F measures 2.156" L × 1.313" W with a maximum seated height of 3.130". The SFA44T7.5K288B-F measures 2.160" L × 1.310" W with a maximum seated height of 3.000". These differences are within acceptable tolerances for standard chassis-mounted holder/bracket installations.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 32FB44075A-F and SFA44T7.5K288B-F are ROHS3 compliant and REACH unaffected. Both carry active product status from Cornell Dubilier Electronics.

Q: What is the lead spacing for each part?

A: The 32FB44075A-F has a lead spacing of 0.813" (20.64mm). The SFA44T7.5K288B-F has a lead spacing of 0.810" (20.57mm). This minimal difference does not affect compatibility with standard quick connect/disconnect termination systems.

Q: Can these parts be used interchangeably in motor run applications?

A: Yes. Both parts are rated for motor run applications and maintain identical electrical specifications required for this use case. They are also suitable for power factor correction (PFC) applications.

Q: What is the moisture sensitivity level for these parts?

A: The 32FB44075A-F has an MSL rating of 1 (Unlimited). The SFA44T7.5K288B-F is not applicable for MSL rating. Both parts are suitable for standard industrial storage and handling conditions.
