PVC4268 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC4268 is a 6800 pF polyester film capacitor rated for 400V DC operation, manufactured by Cornell Dubilier Electronics (CDE) in the PVC series. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The radial through-hole configuration and general-purpose application profile support direct substitution with compatible film capacitor designs meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC4268 is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Requirements (Non-Negotiable):

• Capacitance value: 6800 pF (exact match)
• DC voltage rating: minimum 400V
• AC voltage rating: minimum 200V
• Tolerance: ±10% or tighter

Mechanical Requirements (Non-Negotiable):

• Mounting configuration: Through-hole radial
• Termination type: PC pins
• Package form: Radial lead spacing compatible with 0.500" (12.70mm) or tighter spacing

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required

The substitute part B32620A4682J000 meets all critical electrical parameters with improved tolerance (±5%), maintains through-hole radial configuration, and holds active product status with full regulatory compliance. Dielectric material variation from polyester to polypropylene is acceptable within the functional envelope of general-purpose film capacitor applications at these voltage and frequency ratings.

Engineering Selection Recommendations

Primary Substitute: B32620A4682J000

The B32620A4682J000 qualifies as a direct functional substitute for the PVC4268 based on the following engineering criteria:

1. Electrical Equivalence: Identical capacitance (6800 pF) and voltage ratings (400V DC / 200V AC) satisfy the core electrical requirements. The improved tolerance specification (±5% versus ±10%) provides enhanced circuit performance without introducing incompatibility.

2. Mechanical Compatibility: Both components utilize through-hole radial mounting with PC pin termination. The substitute features tighter lead spacing (0.295" versus 0.500") and more compact physical dimensions, enabling direct board-level substitution with potential PCB layout optimization.

3. Product Status and Availability: The substitute maintains active manufacturing status with 2948 units in stock, ensuring procurement continuity and long-term supply security compared to the obsolete PVC4268.

4. Regulatory Compliance: Both components hold ROHS3 compliance and REACH unaffected status, maintaining full regulatory alignment for applications requiring these certifications.

5. Operating Temperature Consideration: The substitute operates across -55°C to 105°C, which is narrower than the original -55°C to 125°C range. This difference is acceptable for general-purpose applications operating within standard industrial temperature ranges. Applications requiring operation above 105°C require specific thermal analysis.

6. Dielectric Material Transition: The shift from polyester to polypropylene (metallized, stacked configuration) represents a material upgrade in the film capacitor category. Polypropylene dielectrics in this voltage class provide equivalent or superior performance characteristics for general-purpose and high-pulse applications.

Frequently Asked Questions (FAQ)

Q: Can B32620A4682J000 be used as a direct replacement for PVC4268 in existing designs?

A: Yes, for applications operating within -55°C to 105°C. The substitute meets all critical electrical parameters (6800 pF, 400V DC, 200V AC) and maintains through-hole radial configuration. PCB layout verification is required due to tighter lead spacing (0.295" versus 0.500").

Q: What is the significance of the tolerance difference (±10% versus ±5%)?

A: The substitute's tighter tolerance (±5%) provides improved capacitance accuracy. This is a performance enhancement that does not create substitution barriers. Circuits designed for ±10% tolerance will operate within specification with ±5% components.

Q: Does the dielectric material change from polyester to polypropylene affect circuit performance?

A: For general-purpose applications at 400V DC / 200V AC, polypropylene film capacitors provide equivalent or superior performance. Polypropylene exhibits lower dissipation factor and better frequency response characteristics. No functional degradation occurs in standard circuit applications.

Q: Why is the operating temperature range narrower for the substitute?

A: The B32620A4682J000 is rated to 105°C maximum versus 125°C for the original. This reflects the design specifications of the polypropylene dielectric in this product series. Applications requiring operation above 105°C must use alternative components or conduct thermal analysis to confirm safe operation.

Q: Are there any PCB layout considerations when substituting?

A: Yes. The substitute has tighter lead spacing (0.295" versus 0.500"). Verify that PCB pad spacing accommodates the narrower lead pitch. The more compact physical dimensions (10.00mm x 4.00mm versus 8.40mm x 17.80mm) may allow improved board layout efficiency.

Q: What is the inventory status for procurement planning?

A: The PVC4268 (obsolete) has 725 units in stock. The B32620A4682J000 (active) has 2948 units in stock, providing superior long-term availability and supply chain security.

Q: Are both components compliant with current regulatory requirements?

A: Yes. Both the PVC4268 and B32620A4682J000 hold ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.
