23FD3304-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The 23FD3304-F is a 4 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) from the MPF series, rated for 330V AC operation. This component is designed for motor run and power factor correction (PFC) applications, utilizing polypropylene (PP) metallized dielectric technology in a radial, can-style package with quick connect/disconnect termination.

The 23FD3304-F is classified as obsolete. Locating active production alternatives is necessary to ensure long-term supply chain continuity and support for new designs or replacement requirements in existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23FD3304-F is based on strict electrical and mechanical parameter matching within the allowed tolerances for this product category:

Electrical Equivalence Criteria:

• Capacitance value: 4 µF (exact match required)
• Voltage rating: 330V AC minimum (equal or higher acceptable)
• Tolerance: ±10% (matching tolerance ensures circuit performance)
• Dielectric material: Polypropylene (PP), Metallized (same technology required)

Mechanical Compatibility Criteria:

• Package type: Radial, Can (form factor must match)
• Mounting: Chassis Mount, Requires Holder/Bracket (installation method must be compatible)
• Termination: Quick Connect, Disconnect (connection interface must match)
• Lead spacing: 0.813" (20.64mm) (must fit existing holder/bracket)
• Physical dimensions: Must accommodate existing mechanical constraints

Compliance & Availability:

• RoHS3 compliance required for regulatory alignment
• Product status (Active vs. Obsolete) affects supply chain viability
• Moisture Sensitivity Level (MSL): 1 (Unlimited) for handling and storage

The substitute part 23FD3304A-F meets all electrical and mechanical criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Feasibility:

The 23FD3304A-F is a direct electrical and mechanical substitute for the 23FD3304-F. All critical electrical parameters—capacitance, voltage rating, tolerance, and dielectric material—are identical. The mechanical interface, including lead spacing, termination type, and mounting configuration, is fully compatible.

Height Consideration:

The 23FD3304A-F has a maximum seated height of 2.630" (66.80mm) compared to the 23FD3304-F at 2.880" (73.15mm). This 0.250" (6.35mm) reduction in height is within typical mechanical tolerances for chassis-mounted capacitor holders and does not affect electrical performance. Verify that the application's mechanical envelope accommodates this dimension.

Product Status Advantage:

The 23FD3304A-F carries Active product status, ensuring ongoing manufacturing support and supply chain availability. The 23FD3304-F is classified as Obsolete, making the substitute the preferred choice for new designs and long-term supply continuity.

Compliance Alignment:

Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent handling and storage requirements. The 23FD3304A-F includes REACH Unaffected status, providing additional regulatory clarity.

Selection Conclusion:

For motor run and power factor correction applications requiring a 4 µF, 330V AC film capacitor with radial can packaging, the 23FD3304A-F is the recommended active production equivalent to the obsolete 23FD3304-F.

Frequently Asked Questions (FAQ)

Q: Can the 23FD3304A-F be used as a direct replacement for the 23FD3304-F in existing equipment?

A: Yes. The 23FD3304A-F is electrically and mechanically equivalent. All critical parameters—capacitance, voltage rating, tolerance, dielectric material, lead spacing, and termination type—are identical. The substitute's reduced height (2.630" vs. 2.880") is compatible with standard chassis-mounted capacitor holders.

Q: What is the significance of the height difference between these two parts?

A: The 23FD3304A-F is 0.250" (6.35mm) shorter than the 23FD3304-F. This difference is within normal mechanical tolerances for radial can capacitor holders and does not affect electrical performance. Verify that your application's mechanical envelope accommodates this dimension.

Q: Why is the 23FD3304-F listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. The 23FD3304A-F, classified as Active, represents the current production equivalent and is the recommended choice for new designs and ongoing supply requirements.

Q: Are there any compliance or handling differences between these parts?

A: No. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Handling, storage, and environmental requirements are identical. The 23FD3304A-F includes REACH Unaffected status, providing additional regulatory documentation.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications. The 330V AC rating and 4 µF capacitance are standard for these uses in industrial and commercial equipment.

Q: Is the ±10% tolerance the same for both parts?

A: Yes. Both the 23FD3304-F and 23FD3304A-F carry ±10% tolerance, ensuring equivalent capacitance accuracy and circuit performance.

Q: Can these capacitors operate outside the -40°C to 70°C temperature range?

A: No. Both parts are rated for operation within -40°C to 70°C. Operation outside this range may affect performance and reliability.

Q: What is the lead spacing, and why is it important?

A: Both parts have 0.813" (20.64mm) lead spacing. This dimension determines compatibility with chassis-mounted capacitor holders and brackets. Matching lead spacing ensures proper mechanical fit and electrical connection.
