Equivalent & Substitute Parts for 32FD3705A-F

Part Overview

The 32FD3705A-F is a 5 µF film capacitor rated for 370V AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the MPF series. This polypropylene metallized radial capacitor is designed for motor run and power factor correction applications in industrial and commercial equipment. The part is currently active in production with 1,032 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 32FD3705A-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 5 µF
• Tolerance: ±10%
• Voltage rating (AC): 370V
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

• Package type: Radial, Can
• Mounting type: Chassis Mount, Requires Holder/Bracket
• Termination style: Quick Connect, Disconnect
• Operating temperature range: -40°C to 70°C

Compliance Parameters:

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part SFA37T5K219B-F meets all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Cornell Dubilier Electronics and share identical capacitance, tolerance, voltage rating, dielectric composition, and operating temperature specifications. Dimensional variations are within acceptable tolerances for chassis-mounted applications using standard holder/bracket assemblies.

Parameter Comparison

Engineering Selection Recommendations

Both the 32FD3705A-F and SFA37T5K219B-F are active production parts manufactured by Cornell Dubilier Electronics with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Primary Selection (32FD3705A-F): Higher current inventory (1,032 units) supports immediate availability for high-volume production requirements and reduces lead time risk.

Secondary Selection (SFA37T5K219B-F): Acceptable alternative when primary part allocation is exhausted. The SF series variant provides equivalent electrical performance with minor dimensional variations that remain compatible with standard chassis-mount holder/bracket assemblies. Moisture sensitivity level classification differs (SF series listed as Not Applicable versus MPF series MSL 1), but this does not affect substitution eligibility for this application category.

Both parts are 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 SFA37T5K219B-F replace 32FD3705A-F in existing designs?

A: Yes. Both parts share identical electrical specifications (5 µF, ±10%, 370V AC), dielectric composition (polypropylene metallized), and mechanical mounting requirements (chassis mount with holder/bracket). Dimensional variations are within acceptable tolerances for this package category.

Q: What are the key differences between these two parts?

A: The parts differ in series designation (MPF versus SF), manufacturer series classification, and minor dimensional variations. The 32FD3705A-F has a maximum seated height of 2.440 inches, while the SFA37T5K219B-F measures 2.310 inches maximum. Lead spacing differs by 0.003 inches (0.813" versus 0.810"). These variations do not affect functional compatibility in standard chassis-mount applications.

Q: Are both parts RoHS compliant?

A: Yes. Both 32FD3705A-F and SFA37T5K219B-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial equipment.

Q: Which part should be specified for new designs?

A: Either part is acceptable for new designs. Selection should consider current inventory availability and supply chain lead times. The 32FD3705A-F offers higher stock levels (1,032 units), while the SFA37T5K219B-F provides a qualified alternative (905 units in stock).

Q: Do these capacitors require any special handling or installation considerations?

A: Both parts are chassis-mount radial can capacitors that require a holder or bracket assembly for mechanical support. Installation follows standard quick-connect/disconnect termination procedures. Operating temperature limits of -40°C to 70°C must be observed during application design.

Q: Can these parts be used interchangeably in motor run and power factor correction circuits?

A: Yes. Both parts are rated for motor run and power factor correction applications with identical 370V AC voltage ratings and 5 µF capacitance values. They operate across the same temperature range and maintain equivalent performance characteristics in these application categories.
