Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 32FB4404-F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 4 µF (exact match required)
• Voltage Rating - AC: 440V (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 70°C (exact match required)

Mechanical Compatibility Criteria:

• Package / Case: Radial, Can (exact match required)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination: Quick Connect, Disconnect (exact match required)
• Lead Spacing: Tolerance within 0.810" to 0.813" (20.57mm to 20.64mm)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (required)

All three substitute parts meet these criteria. Dimensional variations in height and overall length are acceptable within the constraints of chassis-mount holder/bracket systems, provided lead spacing remains compatible.

Parameter Comparison

Engineering Selection Recommendations

32FB4404A-F (Direct Successor)

The 32FB4404A-F is the recommended primary substitute. This part maintains the MPF series designation and shares identical electrical specifications with the main part. Product status is active, ensuring long-term availability. The height reduction from 2.630" to 2.440" represents a minor dimensional change that remains compatible with standard chassis-mount holder/bracket systems. Lead spacing is identical at 0.813" (20.64mm).

SFA44T4K156B-F and SFA44T4K219B-F (Alternative Series)

Both SF series parts meet all electrical and mechanical substitution criteria. These parts represent alternative product lines from the same manufacturer. The SFA44T4K156B-F offers the most compact height at 1.680" (42.67mm), suitable for space-constrained applications. The SFA44T4K219B-F provides an intermediate height of 2.310" (58.67mm). Both parts have lead spacing of 0.810" (20.57mm), which is within acceptable tolerance for quick-connect termination systems. Both are active products with ROHS3 compliance and REACH unaffected status.

Selection between these three substitutes depends on available space within the chassis-mount holder/bracket assembly and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 32FB4404A-F directly replace the obsolete 32FB4404-F?

A: Yes. The 32FB4404A-F is electrically and mechanically equivalent. All electrical parameters (capacitance, voltage rating, tolerance, dielectric material, operating temperature) are identical. Lead spacing is identical at 0.813" (20.64mm). The seated height is reduced by 0.190" (1.82mm), which is compatible with standard chassis-mount holder/bracket systems.

Q: What is the difference between the MPF series (32FB4404A-F) and the SF series (SFA44T4K156B-F and SFA44T4K219B-F)?

A: All three substitute parts are electrically equivalent. The primary differences are product series designation and physical height. The MPF series part (32FB4404A-F) maintains the original series lineage. The SF series parts (SFA44T4K156B-F and SFA44T4K219B-F) represent an alternative product line with different height specifications. Lead spacing differs slightly (0.813" versus 0.810"), but both are compatible with quick-connect termination systems.

Q: Are there dimensional constraints I should consider when selecting a substitute?

A: Yes. The main part has a seated height of 2.630" (66.80mm). The 32FB4404A-F reduces this to 2.440" (61.98mm). The SFA44T4K156B-F is significantly more compact at 1.680" (42.67mm), while the SFA44T4K219B-F is 2.310" (58.67mm). Verify that your chassis-mount holder/bracket system accommodates the selected height. Lead spacing is 0.813" (20.64mm) for the MPF part and 0.810" (20.57mm) for both SF parts.

Q: Do all substitute parts have the same compliance certifications?

A: All four parts (main and three substitutes) are ROHS3 compliant. The 32FB4404A-F, SFA44T4K156B-F, and SFA44T4K219B-F are all REACH unaffected. All parts have ECCN classification EAR99 and HTSUS code 8532.25.0020.

Q: What is the moisture sensitivity level for these capacitors?

A: The main part 32FB4404-F has MSL 1 (Unlimited). The substitute 32FB4404A-F also has MSL 1 (Unlimited). The SF series parts (SFA44T4K156B-F and SFA44T4K219B-F) have MSL listed as Not Applicable, indicating no moisture sensitivity constraints.

Q: Can I use these capacitors in both motor run and power factor correction applications?

A: Yes. The main part and 32FB4404A-F are specified for both motor run and power factor correction (PFC) applications. The SF series parts (SFA44T4K156B-F and SFA44T4K219B-F) are specified for motor run applications. Verify application compatibility with your system requirements.
