Cornell Dubilier Electronics 32FD3710 Film Capacitor - Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier Electronics 32FD3710 is a 10 µF film capacitor rated for 370V AC operation, utilizing polypropylene (PP) metallized dielectric technology in a radial, can-style package. This component is designed for motor run and power factor correction (PFC) applications requiring chassis mount installation with holder/bracket support. The part maintains active product status with 927 units currently in stock. Alternative equivalent parts may be required due to inventory constraints, application-specific packaging needs, or compliance requirements for new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 32FD3710 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 10 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating (AC): 370V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C to 70°C (exact match required)
• Package Configuration: Radial, Can (exact match required)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination Style: Quick Connect, Disconnect (exact match required)
• Application Compatibility: Motor Run and Power Factor Correction (PFC)

The substitute part SFA37T10K288B-F meets all critical electrical and mechanical parameters, with minor dimensional variations within acceptable tolerances for the specified mounting configuration.

Engineering Selection Recommendations

Primary Selection (32FD3710): Use when existing designs specify this exact part number and RoHS non-compliance is acceptable for the application. Adequate inventory is available for current production requirements.

Substitute Selection (SFA37T10K288B-F): Use when:

• RoHS3 compliance is required for new designs or updated product lines
• Higher inventory availability is needed for extended production runs
• Dimensional variations within the specified ranges are acceptable for the mounting configuration
• The substitute part's increased height (3.000" vs. 2.880") does not conflict with enclosure or assembly constraints

Both parts are manufactured by Cornell Dubilier Electronics and maintain identical electrical performance across all critical parameters. The choice between them is determined by compliance requirements and physical space availability in the target application.

Frequently Asked Questions (FAQ)

Q: Can SFA37T10K288B-F be used as a direct replacement for 32FD3710 in existing assemblies?

A: Yes, provided that the increased height of 3.000" (76.20mm) versus 2.880" (73.15mm) does not create clearance conflicts within the chassis or enclosure. All electrical parameters, capacitance, voltage rating, tolerance, and termination style are identical. Lead spacing differences (0.810" vs. 0.813") are within acceptable tolerances for quick connect/disconnect terminations.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (10 µF), tolerance (±10%), AC voltage rating (370V), dielectric material (polypropylene metallized), and operating temperature range (-40°C to 70°C) must be identical. These parameters determine functional equivalence in motor run and power factor correction applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS3 compliance in the SFA37T10K288B-F indicates adherence to material restriction standards and does not alter electrical characteristics. The difference is relevant only for regulatory and procurement requirements in specific markets or customer specifications.

Q: Are there any packaging or inventory considerations?

A: The 32FD3710 is available in standard packaging with 927 units in stock. The SFA37T10K288B-F is supplied in bulk packaging with 2100 units available. Bulk packaging may require different handling or storage procedures depending on your supply chain requirements.

Q: What mounting considerations apply to both parts?

A: Both parts require chassis mount installation with holder/bracket support. Dimensional compatibility must be verified for the specific mounting configuration, particularly the height specification, which differs by 0.120" (3.05mm) between the two parts.
