Equivalent & Substitute Parts for 32FB4401A-F

Part Overview

The 32FB4401A-F is a 1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) from the MPF series, rated for 440V AC operation. This polypropylene metallized radial capacitor is designed for motor run and power factor correction applications in industrial equipment. The part is currently active in production with 1,149 units in stock. Substitute parts become necessary when the original specification requires higher voltage ratings, different physical dimensions, or when inventory constraints require alternative sourcing from the same manufacturer's product line.

Substitute Part Grouping Explanation

Substitution for the 32FB4401A-F is limited to parts that maintain identical electrical characteristics while permitting higher voltage ratings. The substitute parts SFA66T1K156B-F and SFA66T1K219B-F are qualified substitutes based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 1 µF (identical)
• Tolerance: ±10% (identical)
• Dielectric Material: Polypropylene (PP), Metallized (identical)
• Operating Temperature Range: -40°C ~ 70°C (identical)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (identical)
• Package / Case: Radial, Can (identical)
• Termination: Quick Connect, Disconnect (identical)
• RoHS Status: ROHS3 Compliant (identical)

Allowable Variation:

• Voltage Rating - AC: 660V (higher than 440V, acceptable for uprating)
• Physical Dimensions: Minor variations within radial can form factor
• Series Designation: Different series (MPF vs. SF) permitted within same manufacturer

The substitute parts operate at higher voltage ratings (660V AC) than the original specification (440V AC), making them suitable for applications requiring enhanced voltage margin or for use in higher-voltage system designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 32FB4401A-F remains the preferred choice for applications with 440V AC system voltage specifications. All three parts are active products from Cornell Dubilier Electronics with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial applications.

Substitute Selection Logic:

SFA66T1K156B-F and SFA66T1K219B-F are electrically interchangeable with the 32FB4401A-F for motor run and power factor correction applications. The 660V AC rating of both substitutes provides a 220V margin above the original 440V specification, making them suitable for:

• System designs requiring higher voltage margin
• Applications where 660V rated components are standardized
• Inventory consolidation strategies favoring the SF series

Physical Dimension Considerations:

Height differences exist between the main part and substitutes. The 32FB4401A-F has a maximum seated height of 2.440" (61.98mm), while SFA66T1K156B-F measures 1.680" (42.67mm) and SFA66T1K219B-F measures 2.310" (58.67mm). Lead spacing remains consistent across all three parts (approximately 0.81" / 20.6mm), ensuring mechanical compatibility with standard radial can holders and brackets.

Compliance Status:

All three parts maintain identical RoHS3 compliance and REACH unaffected status, supporting use in regulated industrial equipment without additional environmental or safety documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can SFA66T1K156B-F or SFA66T1K219B-F be used as direct replacements for 32FB4401A-F in a 440V AC circuit?

A: Yes. Both substitute parts are rated for 660V AC, which exceeds the 440V AC requirement of the original specification. The higher voltage rating does not affect performance in lower-voltage applications. All three parts share identical capacitance (1 µF), tolerance (±10%), dielectric material (polypropylene metallized), and operating temperature range (-40°C ~ 70°C).

Q: What are the physical dimension differences between these parts?

A: The main differences are in maximum seated height. The 32FB4401A-F measures 2.440" (61.98mm), SFA66T1K156B-F measures 1.680" (42.67mm), and SFA66T1K219B-F measures 2.310" (58.67mm). Length and width dimensions are nearly identical (approximately 2.16" x 1.31" / 54.8mm x 33.3mm). Lead spacing is consistent at approximately 0.81" (20.6mm) across all parts. Height variation may affect mounting bracket selection or enclosure fit.

Q: Are all three parts suitable for motor run applications?

A: Yes. All three parts list motor run as an application. The 32FB4401A-F additionally lists power factor correction (PFC) as an application. The electrical characteristics supporting motor run operation are identical across all three parts.

Q: What is the difference between SFA66T1K156B-F and SFA66T1K219B-F?

A: Both parts are identical in electrical specifications (1 µF, ±10%, 660V AC, polypropylene metallized, -40°C ~ 70°C). The primary difference is maximum seated height: SFA66T1K156B-F measures 1.680" (42.67mm) while SFA66T1K219B-F measures 2.310" (58.67mm). Selection between these two depends on available mounting space in the application.

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

A: All three parts are chassis mount components requiring a holder or bracket. Termination is via quick connect/disconnect terminals. Lead spacing of approximately 0.81" (20.6mm) is consistent across all parts, supporting use with standard radial can capacitor holders. Moisture sensitivity level for the main part is 1 (unlimited); substitute parts list MSL as not applicable.

Q: Are all three parts currently in stock?

A: Yes. The 32FB4401A-F has 1,149 units in stock, SFA66T1K156B-F has 908 units in stock, and SFA66T1K219B-F has 1,076 units in stock. All are listed as active products.
