Engineering Selection Recommendations

Direct Replacement (Recommended First Choice):

The 32FD3702A-F is the primary direct replacement for the obsolete 32FD3702-F. Both parts are manufactured by Cornell Dubilier Electronics, share identical electrical specifications (2 µF, ±10%, 370V AC), and maintain the same physical form factor and termination style. The 32FD3702A-F is currently in active production status with higher inventory availability (1918 pcs vs. 694 pcs for the original).

Alternative Substitutes (Same Voltage Rating):

The SFA37T2K156B-F provides equivalent electrical performance with identical 370V AC rating. This part belongs to CDE's active SF series and is suitable for direct substitution where space constraints or mechanical mounting requirements align with the specified dimensions.

Higher Voltage Alternatives (440V and 660V Ratings):

Parts rated at 440V AC (SFA44T2K156B-F, SFA44T2K219B-F) and 660V AC (SFA66T2K156B-F, SFA66T2K219B-F) are electrically compatible substitutes for 370V AC applications. These higher-rated components provide additional voltage margin and are suitable for circuits where the application voltage does not exceed the original 370V specification. All substitute parts maintain ROHS3 compliance and the same operating temperature range (-40°C to 70°C).

Compliance and Certification:

All substitute parts carry ROHS3 compliance certification, matching the environmental and regulatory status of the original 32FD3702-F. Parts in the SF series include REACH Unaffected status documentation.

Frequently Asked Questions (FAQ)

Q: Can the 32FD3702A-F directly replace the obsolete 32FD3702-F?

A: Yes. The 32FD3702A-F is a direct equivalent with identical electrical ratings (2 µF, ±10%, 370V AC), dielectric material (polypropylene metallized), package style (radial can), and termination type (quick connect/disconnect). Both parts are manufactured by Cornell Dubilier Electronics and are suitable for motor run and power factor correction applications.

Q: What is the difference between the MPF series (32FD3702-F) and the SF series (SFA37T2K156B-F)?

A: Both series use identical dielectric material (polypropylene metallized) and maintain the same electrical specifications for the 2 µF, 370V AC rating. The SF series represents CDE's current active product line, while the MPF series is obsolete. Physical dimensions are comparable, with minor variations in height and lead spacing that do not affect mechanical compatibility in standard chassis-mount applications.

Q: Can I use a 440V or 660V rated capacitor in place of the 370V 32FD3702-F?

A: Yes. Higher voltage-rated capacitors (440V and 660V) are electrically compatible substitutes for 370V applications. The higher voltage rating provides additional safety margin and does not degrade circuit performance. All substitute parts maintain the same 2 µF capacitance, ±10% tolerance, and operating temperature range.

Q: Are there any physical dimension differences between substitute parts?

A: Minor variations exist in seated height and lead spacing among substitute parts. The 32FD3702-F has a maximum seated height of 2.380" (60.45mm), while SF series parts are rated at 1.680" to 2.310" (42.67mm to 58.67mm) depending on the specific model. Lead spacing is 0.813" (20.64mm) for the original and 0.810" (20.57mm) for SF series alternatives. These differences are within standard mechanical tolerances for chassis-mount applications with holder/bracket systems.

Q: What is the inventory status of substitute parts?

A: The 32FD3702A-F (active MPF series equivalent) has 1918 pcs in stock. SF series alternatives have the following availability: SFA37T2K156B-F (1035 pcs), SFA44T2K156B-F (731 pcs), SFA44T2K219B-F (1049 pcs), SFA66T2K156B-F (1116 pcs), and SFA66T2K219B-F (1196 pcs).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the environmental compliance status of the original 32FD3702-F.
