Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 32FB4405-F are identified based on strict electrical and mechanical parameter matching within the allowed specifications for this product category. The substitution logic is based on the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 5 µF
• Tolerance: ±10%
• Voltage Rating (AC): 440V
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 70°C

Mechanical Parameters (Must Match):

• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Package / Case: Radial, Can
• Termination Type: Quick Connect, Disconnect

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

All substitute parts listed meet these criteria and are therefore electrically and mechanically compatible with the original 32FB4405-F component.

Parameter Comparison

Engineering Selection Recommendations

32FB4405A-F (Primary Substitute): The 32FB4405A-F is the direct successor to the 32FB4405-F within the same MPF series from Cornell Dubilier Electronics. Both components share identical electrical specifications and mechanical dimensions. The 32FB4405A-F carries an active product status, ensuring ongoing availability and supply chain support. This part is the preferred substitute for direct replacement applications. The primary dimensional difference is a reduced seated height (2.440" versus 2.880"), which may provide space advantages in certain mounting configurations while maintaining full electrical compatibility.

SFA44T5K219B-F (Alternative Substitute): The SFA44T5K219B-F is an alternative substitute from the SF series, also manufactured by Cornell Dubilier Electronics. This component meets all critical electrical and mechanical parameters required for substitution. The SFA44T5K219B-F features a further reduced seated height (2.310") and carries an active product status. The lead spacing is nominally equivalent (0.810" versus 0.813"), and the physical dimensions remain within acceptable tolerance for chassis-mounted applications. This part is suitable for applications where space constraints or mounting geometry favor a more compact profile.

Both substitute parts are ROHS3 compliant and maintain the same operating temperature range and dielectric material specifications as the original 32FB4405-F.

Frequently Asked Questions (FAQ)

Q: Can the 32FB4405A-F be used as a direct replacement for the 32FB4405-F?

A: Yes. The 32FB4405A-F is electrically and mechanically equivalent to the 32FB4405-F. Both components have identical capacitance (5 µF), tolerance (±10%), voltage rating (440V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 70°C), and termination type (quick connect/disconnect). The primary difference is the reduced seated height of the 32FB4405A-F (2.440" versus 2.880"), which does not affect electrical performance and may provide mounting advantages.

Q: What is the difference between the 32FB4405A-F and SFA44T5K219B-F?

A: Both parts are electrically equivalent and meet the same electrical specifications. The differences are dimensional and series-based. The 32FB4405A-F belongs to the MPF series with a seated height of 2.440", while the SFA44T5K219B-F belongs to the SF series with a seated height of 2.310". The SFA44T5K219B-F offers a more compact profile. Lead spacing is nominally equivalent (0.813" versus 0.810"). Selection between these two should be based on available mounting space and chassis geometry.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 32FB4405A-F and SFA44T5K219B-F are both ROHS3 compliant, matching the compliance status of the original 32FB4405-F.

Q: Can these capacitors be used in power factor correction (PFC) applications?

A: The 32FB4405A-F is rated for both motor run and power factor correction applications. The SFA44T5K219B-F is rated for motor run applications. Verify application requirements before selecting the SFA44T5K219B-F for PFC-specific installations.

Q: What is the lead spacing tolerance, and does it affect interchangeability?

A: The 32FB4405-F and 32FB4405A-F have identical lead spacing of 0.813" (20.64mm). The SFA44T5K219B-F has a lead spacing of 0.810" (20.57mm), a difference of 0.003". This nominal difference is within acceptable tolerance for quick connect/disconnect termination systems and does not prevent interchangeability in standard chassis-mount applications.

Q: Why is the 32FB4405-F listed as obsolete?

A: The 32FB4405-F carries an obsolete product status, indicating it is no longer in active production. The 32FB4405A-F and SFA44T5K219B-F are active products and represent the current manufacturing alternatives from Cornell Dubilier Electronics.

Q: What is the moisture sensitivity level (MSL) difference?

A: The 32FB4405-F and 32FB4405A-F both have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The SFA44T5K219B-F has MSL listed as Not Applicable, which is typical for film capacitors with can-style packaging. This difference does not affect substitution compatibility.
