Engineering Selection Recommendations

Primary Substitute - 32FD37075A-F: This part is the direct successor within the MPF series, offering active product status while maintaining identical electrical specifications and lead spacing. The reduced height-seated dimension (61.98mm vs. 66.80mm) provides improved space efficiency in compact applications. This part is recommended as the first choice for direct replacement in existing designs.

Alternative Substitutes - SFA37S7.5K156B-F and SFA37T7.5K219B-F: These parts belong to the SF series and provide equivalent electrical performance with active product status. The SFA37S7.5K156B-F offers the most compact form factor (42.67mm height), suitable for space-constrained applications. The SFA37T7.5K219B-F provides an intermediate height option (58.67mm). Both SF series parts maintain ROHS3 compliance and are suitable for motor run applications.

All substitute parts are ROHS3 compliant and carry identical regulatory classifications (EAR99, HTSUS 8532.25.0020), ensuring compliance with environmental and export requirements.

Frequently Asked Questions (FAQ)

Q: Can 32FD37075A-F directly replace 32FD37075-F in existing applications?

A: Yes. The 32FD37075A-F maintains identical electrical specifications (7.5 µF, ±10%, 370V AC), dielectric material, operating temperature range, and lead spacing. The reduced height-seated dimension (61.98mm vs. 66.80mm) is compatible with standard motor run and PFC applications using holder/bracket mounting.

Q: What is the primary difference between the MPF series (32FD37075A-F) and SF series (SFA37S7.5K156B-F, SFA37T7.5K219B-F) substitutes?

A: The MPF and SF series are both manufactured by Cornell Dubilier Electronics with identical electrical ratings. The primary differences are physical dimensions and series designation. The SF series offers compact form factors with active product status. Selection between series depends on available mounting space and mechanical constraints.

Q: Are there height restrictions when selecting between substitute parts?

A: Yes. The substitute parts exhibit different height-seated measurements: 32FD37075A-F (61.98mm), SFA37T7.5K219B-F (58.67mm), and SFA37S7.5K156B-F (42.67mm). Verify available mounting space before selection. All parts maintain compatible lead spacing (approximately 20.6mm) for standard quick connect termination.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts are ROHS3 compliant with EAR99 ECCN classification and HTSUS code 8532.25.0020, matching the regulatory profile of the 32FD37075-F.

Q: Which substitute part is recommended for new designs?

A: For new designs, select from the active product status parts: 32FD37075A-F (MPF series), SFA37S7.5K156B-F, or SFA37T7.5K219B-F (SF series). The 32FD37075A-F is recommended if direct compatibility with existing MPF series designs is required. The SF series parts offer alternative form factors for space-optimized applications.
