Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23FD3305-F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 5 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating (AC): 330V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Package Style: Radial, Can (exact match required)
• Termination Type: Quick Connect, Disconnect (exact match required)
• Operating Temperature Range: -40°C ~ 70°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

The substitute part 23FD3305A-F meets all these criteria. The primary difference is product status (active vs. obsolete) and minor dimensional variation in seated height, which does not affect electrical performance or mechanical compatibility in standard chassis mount applications.

Parameter Comparison

Engineering Selection Recommendations

The 23FD3305A-F is the direct substitute for the obsolete 23FD3305-F. Both parts are manufactured by Cornell Dubilier Electronics within the MPF series and share identical electrical specifications, dielectric composition, and regulatory compliance certifications.

Selection Basis:

• Electrical Equivalence: All critical electrical parameters (capacitance, tolerance, voltage rating, temperature range) are identical.
• Mechanical Compatibility: Lead spacing and termination type are identical. The substitute part is 0.250" shorter in seated height, which is compatible with standard chassis mount applications using holder/bracket assemblies.
• Regulatory Compliance: Both parts are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).
• Product Availability: The 23FD3305A-F is active production status with 762 units in stock, compared to the obsolete 23FD3305-F with 986 units in stock.

The 23FD3305A-F is suitable for direct substitution in motor run and power factor correction (PFC) applications where the 23FD3305-F was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the 23FD3305A-F replace the 23FD3305-F in all applications?

A: Yes. The 23FD3305A-F meets all electrical and mechanical specifications of the 23FD3305-F. Both parts are identical in capacitance (5 µF), tolerance (±10%), voltage rating (330V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 70°C), and termination type (quick connect/disconnect). The substitute part is 0.250" shorter in seated height, which does not affect compatibility in standard chassis mount applications.

Q: What is the difference between the 23FD3305-F and 23FD3305A-F?

A: The primary differences are: (1) Product status—23FD3305-F is obsolete while 23FD3305A-F is active production; (2) Seated height—23FD3305-F is 2.880" maximum while 23FD3305A-F is 2.630" maximum; (3) Packaging—23FD3305-F is packaged as individual units while 23FD3305A-F is bulk packaged. All electrical parameters and mechanical interfaces are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 23FD3305-F and 23FD3305A-F are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: What applications are these capacitors designed for?

A: Both parts are specified for motor run and power factor correction (PFC) applications. They are chassis mount components requiring a holder/bracket assembly.

Q: Does the height difference affect installation?

A: The 23FD3305A-F is 0.250" shorter than the 23FD3305-F. In standard chassis mount applications with holder/bracket assemblies, this dimensional difference does not affect installation compatibility. Verify available space in your specific application before substitution.

Q: What is the lead spacing for these capacitors?

A: Both parts have identical lead spacing of 0.813" (20.64mm), ensuring compatibility with standard holder/bracket assemblies designed for the 23FD3305-F.
