Equivalent & Substitute Parts: Cornell Dubilier Electronics 23FD3306

Part Overview

The Cornell Dubilier Electronics 23FD3306 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 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure design continuity, and support ongoing maintenance and repair operations where original inventory may become unavailable.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical 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)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Termination style: Quick Connect, Disconnect (exact match required)
• Lead spacing: 0.813" (20.64mm) (exact match required)
• Mounting type: Chassis Mount, Requires Holder/Bracket (exact match required)

Environmental Parameters:

• Operating temperature range: -40°C to 70°C (exact match required)

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation. Physical dimensions (diameter and height) may vary within the constraints of the radial can package format, provided the part maintains mechanical compatibility with standard holder/bracket installations.

Parameter Comparison

Engineering Selection Recommendations

The 23FD3306A-F is a direct functional equivalent to the obsolete 23FD3306. Both parts are manufactured by Cornell Dubilier Electronics within the MPF series and satisfy identical electrical, mechanical, and environmental specifications for motor run and power factor correction applications.

Product Status Consideration: The 23FD3306 is classified as obsolete, while the 23FD3306A-F maintains active product status. Selection of the 23FD3306A-F ensures access to current manufacturing, ongoing availability, and manufacturer support.

Compliance Advantage: The 23FD3306A-F achieves ROHS3 compliance and REACH unaffected status, whereas the 23FD3306 is RoHS non-compliant. For applications subject to regulatory requirements or environmental standards, the 23FD3306A-F provides improved compliance posture.

Physical Dimension Variation: The seated height differs between parts (2.880" for 23FD3306 versus 2.630" for 23FD3306A-F). This 0.250" reduction in height remains compatible with standard radial can holder/bracket installations and does not affect electrical performance or mechanical mounting integrity.

Selection Basis: Choose 23FD3306A-F for new designs, system upgrades, and replacement applications where regulatory compliance and product availability are required. The 23FD3306 may be retained only where existing inventory is available and regulatory constraints do not apply.

Frequently Asked Questions (FAQ)

Q: Can the 23FD3306A-F directly replace the 23FD3306 in existing applications?

A: Yes. The 23FD3306A-F satisfies all electrical, mechanical, and environmental parameters of the 23FD3306. Both parts share identical capacitance (6 µF), voltage rating (330V AC), dielectric material (polypropylene metallized), package type (radial can), termination style (quick connect/disconnect), and lead spacing (0.813"). The seated height variation (0.250" difference) does not affect compatibility with standard holder/bracket installations.

Q: What is the significance of the product status difference?

A: The 23FD3306 is obsolete, indicating discontinued manufacturing and limited availability. The 23FD3306A-F is active, ensuring current production, ongoing supply chain access, and manufacturer technical support. For maintenance and repair operations, the active status of 23FD3306A-F provides long-term component availability.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical capacitance, voltage rating, and operating characteristics. The ROHS3 compliance of 23FD3306A-F addresses regulatory requirements in applications subject to environmental standards.

Q: Are there any dimensional constraints I should consider?

A: The 23FD3306A-F has a maximum seated height of 2.630" compared to 2.880" for the 23FD3306. This 0.250" reduction is compatible with standard radial can holder/bracket designs. Verify available space in your specific installation, but this variation typically does not create mounting conflicts.

Q: Can I use these parts interchangeably in motor run and PFC applications?

A: Yes. Both parts are rated for motor run and power factor correction applications and maintain identical operating temperature ranges (-40°C to 70°C). Electrical performance and application suitability are equivalent.

Q: What should I verify before substitution?

A: Confirm that your application requires 6 µF capacitance at 330V AC with ±10% tolerance. Verify that the radial can package with quick connect/disconnect termination and 0.813" lead spacing matches your circuit board or holder/bracket design. Confirm that the 0.250" height difference does not create space constraints in your installation.
