Equivalent & Substitute Parts: 23FD3306-F

Part Overview

The Cornell Dubilier Electronics (CDE) 23FD3306-F is a 6 µF film capacitor rated for 330V AC operation, utilizing polypropylene (PP) metallized dielectric technology in a radial, can-style package. This component is designed for motor run and power factor correction (PFC) applications requiring chassis mount installation with holder/bracket support.

The 23FD3306-F carries an obsolete product status. Identification of functionally equivalent substitute parts is necessary to maintain system continuity and ensure procurement availability for replacement, repair, and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the 23FD3306-F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 6 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating (AC): 330V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 70°C (exact match required)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.813" (20.64mm) (exact match required)
• Termination: Quick Connect, Disconnect (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part 23FD3306A-F meets all specified electrical and mechanical parameters. Variations in product status (obsolete vs. active) and packaging designation (tape/reel vs. bulk) do not affect functional equivalence when all electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The 23FD3306A-F is a direct functional equivalent to the 23FD3306-F for all electrical and mechanical applications. Selection between these parts should be based on the following criteria:

Product Status Consideration: The 23FD3306A-F carries active product status from Cornell Dubilier Electronics, ensuring ongoing availability and manufacturing support. The 23FD3306-F is obsolete, making the substitute the preferred choice for new designs and long-term procurement planning.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical electrical specifications (6 µF, ±10%, 330V AC, polypropylene metallized dielectric, -40°C ~ 70°C operating range). Both are suitable for motor run and power factor correction applications.

Physical Dimension Variance: The 23FD3306A-F has a maximum seated height of 2.630" (66.80mm), compared to 2.880" (73.15mm) for the 23FD3306-F. This 0.250" reduction in height may provide space optimization benefits in chassis-mounted applications. Verify that the reduced height does not conflict with existing mechanical constraints or holder/bracket specifications in the target application.

Packaging and Inventory: The 23FD3306A-F is available in bulk packaging with 988 pieces in stock, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 23FD3306A-F be used as a direct replacement for the 23FD3306-F in existing applications?

A: Yes. The 23FD3306A-F meets all electrical specifications (6 µF, ±10%, 330V AC, polypropylene metallized dielectric, -40°C ~ 70°C operating range) and mechanical requirements (radial can package, 0.813" lead spacing, quick connect/disconnect termination, chassis mount with holder/bracket). The primary consideration is the 0.250" reduction in seated height, which must be verified against mechanical constraints in the specific application.

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

A: The 23FD3306A-F has a maximum seated height of 2.630" (66.80mm), while the 23FD3306-F measures 2.880" (73.15mm). This 0.250" difference may allow for improved space utilization in compact chassis designs. However, if the original design relies on the taller profile for mechanical clearance or holder/bracket compatibility, the reduced height must be evaluated against the specific mounting configuration.

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

A: No. Both parts are ROHS3 compliant and carry identical environmental and regulatory certifications. Both are suitable for motor run and power factor correction applications without compliance restrictions.

Q: Why is the 23FD3306-F listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation and market demand. The 23FD3306A-F, as an active product from the same manufacturer and series, provides continuity for applications requiring this capacitor specification.

Q: Are the lead spacing and termination type identical?

A: Yes. Both parts feature 0.813" (20.64mm) lead spacing and quick connect/disconnect termination, ensuring compatibility with existing holder/bracket assemblies and PCB layouts designed for the original part.
