Engineering Selection Recommendations

32FD37125A-F (Primary Substitute)

The 32FD37125A-F is the direct successor to the 32FD37125-F within the same MPF series from Cornell Dubilier Electronics. This part carries active product status and maintains identical electrical specifications and mechanical compatibility. The 32FD37125A-F is ROHS3 compliant and REACH unaffected, supporting modern supply chain requirements. Physical dimensions are virtually identical to the main part, with a marginal reduction in seated height (3.130" versus 3.250"), which remains compatible with standard chassis mounting configurations. Lead spacing is identical at 0.813" (20.64mm).

SFA37T12.5K288B-F (Secondary Substitute)

The SFA37T12.5K288B-F represents an alternative from the SF series, also manufactured by Cornell Dubilier Electronics. This part maintains all critical electrical parameters and is active in production. The SFA37T12.5K288B-F exhibits a reduced seated height of 3.000" (76.20mm) and marginally tighter dimensional tolerances across length, width, and lead spacing. These dimensional variations remain within acceptable mechanical compatibility ranges for chassis-mounted applications. This part is ROHS3 compliant and REACH unaffected. The MSL rating is listed as not applicable, indicating different packaging or handling protocols compared to the main part.

Both substitute parts satisfy the electrical and mechanical requirements for direct substitution in motor run and power factor correction applications operating at 370V AC with 12.5 µF capacitance.

Frequently Asked Questions (FAQ)

Q: Can the 32FD37125A-F be used as a direct replacement for the 32FD37125-F?

A: Yes. The 32FD37125A-F is electrically and mechanically equivalent to the 32FD37125-F. Both parts share identical capacitance (12.5 µF), tolerance (±10%), voltage rating (370V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C to 70°C), package type (radial can), mounting configuration (chassis mount with holder/bracket), and termination style (quick connect/disconnect). Lead spacing is identical at 0.813" (20.64mm). The 32FD37125A-F carries active product status, making it the recommended primary substitute.

Q: What are the dimensional differences between the substitute parts and the main part?

A: The 32FD37125A-F has a seated height of 3.130" compared to the main part's 3.250", a reduction of 0.120". The SFA37T12.5K288B-F has a seated height of 3.000", a reduction of 0.250". Length and width dimensions are virtually identical across all three parts, with variations within 0.004" to 0.010". Lead spacing varies minimally: 0.813" for the main part and 32FD37125A-F, and 0.810" for the SFA37T12.5K288B-F. These dimensional variations remain compatible with standard chassis mounting brackets and holders.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the 32FD37125A-F and SFA37T12.5K288B-F are ROHS3 compliant. The 32FD37125A-F also carries REACH unaffected status. The SFA37T12.5K288B-F is REACH unaffected as well. All three parts share the same ECCN (EAR99) and HTSUS code (8532.25.0020).

Q: What is the difference between the MPF and SF series designations?

A: The 32FD37125-F and 32FD37125A-F belong to the MPF series, while the SFA37T12.5K288B-F belongs to the SF series. Both series are manufactured by Cornell Dubilier Electronics and meet identical electrical and mechanical specifications for this 12.5 µF, 370V AC application. The series designation reflects internal product line organization but does not affect functional equivalence.

Q: Can the SFA37T12.5K288B-F be used in applications where the 32FD37125-F was originally specified?

A: Yes. The SFA37T12.5K288B-F meets all electrical requirements (12.5 µF, ±10% tolerance, 370V AC, polypropylene metallized dielectric, -40°C to 70°C operating range) and mechanical requirements (radial can package, chassis mount configuration, quick connect/disconnect termination). The reduced seated height of 3.000" is compatible with standard mounting brackets. This part is suitable for motor run and power factor correction applications.

Q: What is the MSL rating difference between the parts?

A: The 32FD37125-F and 32FD37125A-F both carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The SFA37T12.5K288B-F lists MSL as not applicable, reflecting different packaging protocols. This difference does not affect functional performance or substitution suitability.

Q: Are there any inventory considerations when selecting a substitute?

A: The 32FD37125-F (obsolete) has 889 pieces in stock. The 32FD37125A-F (active) has 744 pieces available. The SFA37T12.5K288B-F (active) has 970 pieces in stock. Inventory levels should be verified at the time of procurement, as availability may change.
