Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 32FD37075 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 7.5 µF
• Tolerance: ±10%
• Voltage Rating (AC): 370V
• Dielectric Material: Polypropylene (PP), Metallized
• Package Type: Radial, Can
• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Termination: Quick Connect, Disconnect
• Operating Temperature Range: -40°C to 70°C
• Applications: Motor Run

All substitute parts listed maintain these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) and lead spacing remain within acceptable tolerances for chassis-mounted can-style capacitors. Product status transitions from obsolete to active represent supply availability improvements rather than functional changes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 32FD37075A-F

The 32FD37075A-F is the direct successor to the obsolete 32FD37075. Both parts belong to the Cornell Dubilier MPF series and maintain identical electrical specifications. The 32FD37075A-F carries active product status with ROHS3 compliance, providing improved regulatory alignment for new designs and ongoing production. Physical dimensions show minimal variation (height difference of 0.190 inches / 4.82 mm), compatible with existing chassis mount installations. This part is the preferred choice for direct replacement applications.

Secondary Substitutes: SFA37T7.5K219B-F, SFA37S7.5K156B-F, SFA37S7.5K219B

These parts represent the SF series alternative from Cornell Dubilier, maintaining all critical electrical parameters. The SFA37T7.5K219B-F offers ROHS3 compliance and active status, making it suitable for applications requiring regulatory certification. The SFA37S7.5K156B-F provides the most compact form factor (height 1.680 inches / 42.67 mm) while maintaining full electrical equivalence, applicable where space constraints exist. The SFA37S7.5K219B remains available with active status but carries RoHS non-compliance designation.

All substitute parts share identical capacitance, voltage rating, tolerance, dielectric material, and operating temperature specifications with the original 32FD37075.

Frequently Asked Questions (FAQ)

Q: Can the 32FD37075A-F directly replace the obsolete 32FD37075 in existing equipment?

A: Yes. The 32FD37075A-F is electrically and mechanically equivalent to the 32FD37075. Both parts feature identical capacitance (7.5 µF), voltage rating (370V AC), tolerance (±10%), dielectric material (PP metallized), and termination type (Quick Connect, Disconnect). The height difference of 0.190 inches is within acceptable tolerance for chassis-mounted can-style capacitors. Existing holder/bracket installations accommodate this variation.

Q: What is the difference between the MPF series (32FD37075A-F) and SF series (SFA37T7.5K219B-F) substitutes?

A: Both series maintain identical electrical specifications for this 7.5 µF, 370V AC application. The primary differences are series designation and physical dimensions. The SF series parts feature slightly different case geometry (length 2.160 inches versus 2.156 inches, width 1.310 inches versus 1.313 inches). These variations remain within acceptable mechanical tolerances for radial can-style capacitor installations.

Q: Which substitute part offers the best regulatory compliance?

A: The 32FD37075A-F and SFA37T7.5K219B-F both carry ROHS3 compliance certification. For applications requiring RoHS compliance, either part is suitable. The 32FD37075A-F maintains the original MPF series lineage, while the SFA37T7.5K219B-F represents the SF series alternative with equivalent compliance status.

Q: Are there space constraints that would favor one substitute over another?

A: The SFA37S7.5K156B-F offers the most compact height at 1.680 inches (42.67 mm), compared to 2.310-2.440 inches for other substitutes. If chassis space is limited, this part provides full electrical equivalence in a reduced form factor. All parts maintain compatible lead spacing (0.810-0.813 inches) for quick connect/disconnect terminations.

Q: Can these substitutes be used in motor run and power factor correction (PFC) applications?

A: Yes. All listed substitute parts carry motor run and power factor correction application designations. The 7.5 µF capacitance, 370V AC rating, and polypropylene metallized dielectric are specified for these applications across all equivalent parts.

Q: What is the inventory status for these substitute parts?

A: Current inventory levels are: 32FD37075A-F (845 pcs), SFA37S7.5K156B-F (687 pcs), SFA37S7.5K219B (1104 pcs), and SFA37T7.5K219B-F (777 pcs). All parts are listed as new original stock.
