Variations in physical dimensions, series designation, and product status are noted but do not affect functional interchangeability within the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

38FB4460A-F is the direct parametric equivalent within the MPF series. This part maintains identical physical dimensions, lead spacing, and height specifications as the original 38FB4460. The 38FB4460A-F carries active product status and ROHS3 compliance, providing a direct replacement path for applications requiring series continuity and identical form factor.

SFD44T60K391B-F is a cross-series substitute from the SF series. This part delivers equivalent electrical performance and mechanical compatibility with a reduced seated height of 4.030 inches compared to the original 5.000 inches. The SFD44T60K391B-F is ROHS3 compliant and carries active product status. The height reduction may require mechanical evaluation in space-constrained installations.

SFD44S60K391B is an active-status substitute within the SF series with identical electrical and mechanical specifications to the SFD44T60K391B-F. This part maintains RoHS non-compliant status and is available in standard packaging configurations.

Selection between these substitutes depends on compliance requirements and physical space constraints. For applications requiring ROHS3 compliance, both SFD44T60K391B-F and 38FB4460A-F are suitable. For applications with height restrictions, SFD44T60K391B-F and SFD44S60K391B offer reduced profile options.

Frequently Asked Questions (FAQ)

Q: Can the 38FB4460A-F be used as a direct replacement for the 38FB4460?

A: Yes. The 38FB4460A-F maintains identical capacitance (60 µF), voltage rating (440V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 70°C), mounting type, package type, and termination specifications. Physical dimensions and lead spacing are identical. The primary difference is active product status and ROHS3 compliance.

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

A: The SF series substitutes (SFD44S60K391B and SFD44T60K391B-F) deliver identical electrical performance and mechanical compatibility. The primary differences are series designation, reduced seated height (4.030 inches versus 5.000 inches), and minor lead spacing variation (0.810 inches versus 0.813 inches). These dimensional differences are within typical mechanical tolerance ranges for chassis-mounted applications.

Q: Are there RoHS compliance considerations for substitute selection?

A: Yes. The original 38FB4460 is RoHS non-compliant. The 38FB4460A-F and SFD44T60K391B-F are ROHS3 compliant. The SFD44S60K391B remains RoHS non-compliant. Applications subject to RoHS regulatory requirements must specify either 38FB4460A-F or SFD44T60K391B-F.

Q: Will the reduced height of the SF series substitutes affect installation?

A: The SF series substitutes (SFD44S60K391B and SFD44T60K391B-F) have a maximum seated height of 4.030 inches compared to 5.000 inches for the original 38FB4460 and 38FB4460A-F. This 0.970-inch reduction may provide installation advantages in space-constrained applications. Mechanical evaluation is necessary only if the original installation space was designed with minimal clearance above the capacitor.

Q: What applications are these film capacitors suitable for?

A: All listed parts are rated for motor run and power factor correction (PFC) applications. The 38FB4460 and 38FB4460A-F specifically list both applications. The SF series substitutes list motor run applications. All parts operate within the -40°C ~ 70°C temperature range and maintain 440V AC rating across the full operating spectrum.

Q: How do lead spacing variations affect circuit board compatibility?

A: Lead spacing differences between the MPF series (0.813 inches) and SF series (0.810 inches) represent a 0.003-inch variation. This difference is negligible for chassis-mounted applications using quick connect termination. For applications with fixed mounting holes, mechanical verification of the specific installation configuration is necessary.
