Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 32FB4410-F is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 10 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage rating (AC): 440V (exact match)
• Dielectric material: Polypropylene (PP), Metallized (exact match)
• Operating temperature range: -40°C to 70°C (exact match or better)

Mechanical Equivalence Requirements:

• Package type: Radial, Can (exact match)
• Mounting type: Chassis Mount, Requires Holder/Bracket (exact match)
• Termination: Quick Connect, Disconnect (exact match)
• Lead spacing: 0.813" ±0.003" (20.64mm ±0.08mm tolerance)

Compliance Requirements:

• RoHS3 Compliant status
• ECCN and HTSUS classifications maintained

The two substitute parts listed—32FB4410A-F and SFA44T10K388B-F—meet all electrical and mechanical equivalence criteria. Both are active products from Cornell Dubilier Electronics, offering direct functional replacement for the obsolete 32FB4410-F.

Parameter Comparison

Engineering Selection Recommendations

32FB4410A-F Selection Criteria:

The 32FB4410A-F is the primary active equivalent for the obsolete 32FB4410-F. Both components belong to the same MPF series from Cornell Dubilier Electronics. The 32FB4410A-F maintains identical electrical specifications and mechanical compatibility. The primary difference is reduced seated height (3.130" versus 4.000"), which provides a space advantage in compact chassis designs while maintaining all functional equivalence. This part carries active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance.

SFA44T10K388B-F Selection Criteria:

The SFA44T10K388B-F represents an alternative from the SF series, also manufactured by Cornell Dubilier Electronics. This part meets all electrical equivalence requirements and maintains mechanical compatibility within acceptable tolerances. The lead spacing of 0.810" (20.57mm) differs marginally from the 0.813" specification but remains within standard manufacturing tolerances for quick connect termination systems. The seated height of 3.870" positions this option between the original and the 32FB4410A-F. This part is active with ROHS3 compliance and REACH unaffected status.

Compliance and Availability:

Both substitute parts maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory alignment with the original component. Current inventory levels support immediate procurement: 32FB4410A-F (830 units) and SFA44T10K388B-F (999 units).

Frequently Asked Questions (FAQ)

Q: Can the 32FB4410A-F directly replace the obsolete 32FB4410-F in existing motor run applications?

A: Yes. The 32FB4410A-F provides direct electrical and mechanical replacement. Both components share identical capacitance (10 µF), voltage rating (440V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 70°C), and termination style (quick connect/disconnect). The reduced seated height (3.130" versus 4.000") is a physical advantage that does not affect functional performance in motor run circuits.

Q: What is the significance of the lead spacing difference between 32FB4410A-F and SFA44T10K388B-F?

A: The lead spacing difference (0.813" versus 0.810") represents a 0.03" variance. For quick connect termination systems, this difference falls within standard manufacturing tolerances and does not prevent mechanical compatibility with standard holder/bracket assemblies. Component selection should be based on specific bracket specifications for your application.

Q: Are both substitute parts suitable for power factor correction applications?

A: The 32FB4410A-F is explicitly rated for power factor correction applications. The SFA44T10K388B-F specifications provided do not list power factor correction as an application, though the electrical parameters are identical. For power factor correction circuits, the 32FB4410A-F is the recommended selection.

Q: What is the impact of the height difference between the three parts?

A: The original 32FB4410-F has a seated height of 4.000" (101.60mm), while the 32FB4410A-F measures 3.130" (79.50mm) and the SFA44T10K388B-F measures 3.870" (98.30mm). These differences affect physical mounting space but do not impact electrical performance. Selection should be based on available chassis clearance and holder/bracket specifications.

Q: Do both substitute parts maintain the same RoHS and regulatory compliance as the original?

A: Yes. Both 32FB4410A-F and SFA44T10K388B-F are ROHS3 compliant with EAR99 ECCN classification and REACH unaffected status, matching the regulatory profile of the obsolete 32FB4410-F.

Q: Which substitute part should be selected for new designs?

A: The 32FB4410A-F is the primary recommendation for new designs due to active product status within the same MPF series, explicit power factor correction application rating, and superior space efficiency. The SFA44T10K388B-F serves as an alternative when specific height or series requirements necessitate the SF series option.
