Substitute Part Grouping Explanation

Substitution eligibility for the 23FD3303-F is determined by strict equivalence across the following critical parameters:

Mandatory Match Criteria:

• Capacitance: 3 µF (exact)
• Tolerance: ±10% (exact)
• Voltage Rating - AC: 330V (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 70°C (minimum)
• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Package / Case: Radial, Can
• Termination: Quick Connect, Disconnect
• Lead Spacing: 0.813" (20.64mm)
• Applications: Motor Run and/or Power Factor Correction (PFC)

Compliance Requirements:

• RoHS3 Compliant status required for new production and regulated markets

The substitute part 23FD3303A-F meets all mandatory criteria. Physical dimensions (diameter and height) may vary within the radial can package envelope while maintaining the same lead spacing and termination method. Inventory status and product lifecycle stage (active vs. obsolete) do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

The 23FD3303A-F is a direct electrical and functional equivalent to the 23FD3303-F. Both components share identical electrical specifications, dielectric composition, voltage rating, capacitance value, tolerance, operating temperature range, and termination method.

Substitution Basis:

The 23FD3303A-F is classified as active product status, whereas the 23FD3303-F is obsolete. This makes the 23FD3303A-F the appropriate selection for new production, repair, and maintenance applications requiring a 3 µF, 330V AC film capacitor in the MPF series.

Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.25.0020), ensuring compatibility with environmental and trade regulations.

Physical Dimension Consideration:

The 23FD3303A-F has a smaller physical envelope (1.875" diameter, 2.630" height) compared to the 23FD3303-F (2.125" diameter, 2.880" height). Lead spacing remains constant at 0.813" (20.64mm). Mechanical installation compatibility depends on the available space within the chassis mount bracket or holder. If space constraints exist in the original design, physical verification of the mounting location is necessary before component selection.

Frequently Asked Questions (FAQ)

Q: Can the 23FD3303A-F replace the 23FD3303-F in motor run applications?

A: Yes. Both components are rated for motor run applications with identical 3 µF capacitance, 330V AC voltage rating, and polypropylene metallized dielectric. The electrical performance is equivalent.

Q: Are there any voltage or capacitance differences between these parts?

A: No. Both parts have 3 µF capacitance with ±10% tolerance and 330V AC voltage rating. They are electrically identical.

Q: What is the difference between these two parts?

A: The primary differences are product status (23FD3303-F is obsolete; 23FD3303A-F is active) and physical dimensions. The 23FD3303A-F is smaller in diameter (1.875" vs. 2.125") and height (2.630" vs. 2.880"). Lead spacing and all electrical parameters remain identical.

Q: Will the 23FD3303A-F fit in the same mounting bracket as the 23FD3303-F?

A: Lead spacing is identical (0.813"), so hole alignment is compatible. However, the smaller diameter and height of the 23FD3303A-F may affect mechanical fit depending on bracket design. Physical verification of available space is required.

Q: Are both parts RoHS compliant?

A: Yes. Both the 23FD3303-F and 23FD3303A-F are ROHS3 compliant.

Q: Can these parts be used in power factor correction (PFC) circuits?

A: Yes. Both components are rated for power factor correction applications and share identical electrical specifications required for PFC circuits.

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 0.813" (20.64mm), which determines PCB or mounting bracket hole alignment.

Q: Is the 23FD3303A-F available in stock?

A: Inventory status is subject to current availability. The 23FD3303A-F is classified as active product, making it more likely to be available through distribution channels compared to the obsolete 23FD3303-F.
