Substitute Part Grouping Explanation

Substitution of the 32FB4402-F is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

Capacitance: 2 µF
Tolerance: ±10%
Dielectric Material: Polypropylene (PP), Metallized
Package / Case: Radial, Can
Termination: Quick Connect, Disconnect
Mounting Type: Chassis Mount, Requires Holder/Bracket
Operating Temperature Range: -40°C ~ 70°C

Voltage Rating Considerations: Substitute parts are grouped into two voltage categories: 440V AC rated and 660V AC rated. Parts rated at 660V AC are electrically compatible with 440V AC circuits and provide enhanced voltage margin. Parts rated at 440V AC provide direct voltage equivalence.

Physical Dimension Variations: Substitute parts exhibit variations in seated height and lead spacing within acceptable mechanical tolerances. These variations require verification against specific mounting bracket and holder specifications in the target application.

Series Designation: The 32FB4402-F (MPF series) is succeeded by active production parts in the SF series (SFA44T2K156B-F, SFA44T2K219B-F, SFA66T2K156B-F, SFA66T2K219B-F) and the direct successor 32FB4402A-F (MPF series).

Engineering Selection Recommendations

Direct Series Successor (Recommended for MPF Series Replacement):

The 32FB4402A-F is the active production equivalent within the same MPF series. This part maintains identical electrical specifications (2 µF, ±10%, 440V AC, PP metallized dielectric) and mechanical compatibility with the 32FB4402-F. The primary difference is reduced seated height (2.440" versus 3.250"), which requires verification against existing mounting bracket clearances. This part is ROHS3 compliant and carries active product status.

Alternative Series Substitutes (SF Series):

The SFA44T2K156B-F and SFA44T2K219B-F are active production alternatives in the SF series, maintaining 440V AC voltage rating equivalence. These parts feature compact form factors with seated heights of 1.680" and 2.150" respectively. Lead spacing is nominally equivalent (0.810" versus 0.813"). Selection between these two SF series options depends on available mounting height in the target application.

Higher Voltage Rated Alternatives (660V AC):

The SFA66T2K156B-F and SFA66T2K219B-F provide 660V AC rating, suitable for applications where enhanced voltage margin is required. These parts are electrically compatible with 440V AC circuits and offer the same capacitance and tolerance specifications. Seated heights are 1.680" and 2.310" respectively.

Compliance and Availability:

All substitute parts are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain continuity. The 32FB4402-F, classified as obsolete, should be replaced with one of the active alternatives listed above.

Frequently Asked Questions (FAQ)

Q: Can the 32FB4402A-F directly replace the 32FB4402-F?

A: The 32FB4402A-F is electrically and mechanically equivalent to the 32FB4402-F, with identical capacitance (2 µF), tolerance (±10%), voltage rating (440V AC), and dielectric material (PP metallized). The primary difference is seated height: 2.440" versus 3.250". Verify that the reduced height accommodates the existing mounting bracket and holder configuration.

Q: What is the difference between 440V and 660V rated parts?

A: The 440V rated parts (32FB4402A-F, SFA44T2K156B-F, SFA44T2K219B-F) are rated for direct operation at 440V AC. The 660V rated parts (SFA66T2K156B-F, SFA66T2K219B-F) are rated for higher voltage operation and are electrically compatible with 440V AC circuits, providing additional voltage safety margin. Selection depends on application voltage requirements and design margin specifications.

Q: Are there physical dimension differences between substitute parts?

A: Yes. The 32FB4402-F has a seated height of 3.250" (82.55mm) and lead spacing of 0.813" (20.64mm). The SF series substitutes have seated heights ranging from 1.680" to 2.310" and lead spacing of 0.810" (20.57mm). These variations require verification against specific mounting bracket and holder specifications to ensure proper fit and electrical connection.

Q: Which substitute part should I select for a space-constrained application?

A: The SFA44T2K156B-F and SFA66T2K156B-F offer the most compact form factor with seated heights of 1.680" (42.67mm). Selection between 440V and 660V rating depends on circuit voltage requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (32FB4402A-F, SFA44T2K156B-F, SFA44T2K219B-F, SFA66T2K156B-F, SFA66T2K219B-F) are ROHS3 compliant.

Q: What is the lead spacing tolerance between the original and substitute parts?

A: The 32FB4402-F has lead spacing of 0.813" (20.64mm). The SF series substitutes have lead spacing of 0.810" (20.57mm), a difference of 0.003" (0.07mm). This nominal variation is within standard mechanical tolerances for quick connect/disconnect termination systems.

Q: Can I use a 660V rated part in a 440V application?

A: Yes. The 660V rated parts (SFA66T2K156B-F, SFA66T2K219B-F) are electrically compatible with 440V AC circuits. The higher voltage rating provides additional safety margin and does not affect circuit performance at 440V operation.
