PVC6033 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6033 is a 0.33 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600V DC operation with polyester dielectric material. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The radial through-hole mounting configuration and ±10% tolerance make this capacitor suitable for general-purpose applications requiring stable capacitance performance across extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC6033 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 0.33 µF
• Tolerance: ±10%
• Voltage rating: Minimum 600V DC
• Dielectric type: Polyester
• Mounting configuration: Through-hole radial

Acceptable Variation Parameters:

• Voltage rating may exceed 600V DC (higher ratings provide design margin)
• AC voltage rating may differ based on dielectric construction
• Physical dimensions may vary within PCB layout constraints
• Operating temperature range may differ if application requirements are met

The ECQ-E6334KF from Panasonic Electronic Components qualifies as a direct substitute based on matching capacitance, tolerance, dielectric material, and exceeding the minimum voltage requirement at 630V DC.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6334KF is electrically equivalent to the PVC6033 for applications requiring 0.33 µF capacitance at 600V DC with ±10% tolerance. Both components are ROHS3 compliant and suitable for general-purpose applications.

Electrical Compatibility: The ECQ-E6334KF exceeds the voltage specification of the original part (630V vs. 600V), providing additional design margin. The metallized polyester dielectric construction of the substitute offers equivalent performance characteristics.

Temperature Consideration: The PVC6033 operates across -55°C to 125°C, while the ECQ-E6334KF operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must retain the original PVC6033 specification or identify alternative parts with extended temperature ratings.

Physical Layout: Lead spacing differs between parts (38.90mm vs. 22.50mm). PCB layout modifications are required when substituting the ECQ-E6334KF for the PVC6033. Physical dimensions must be verified against available board space.

Procurement Status: The ECQ-E6334KF is active production status with 1022 units in stock, compared to the obsolete PVC6033 with 792 units remaining inventory.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6334KF directly replace the PVC6033 without circuit modification?

A: Electrical substitution is valid. The ECQ-E6334KF meets all electrical requirements (0.33 µF, ±10%, 630V DC minimum). However, PCB layout modification is required due to different lead spacing (38.90mm vs. 22.50mm) and physical dimensions.

Q: What is the significance of the metallized polyester dielectric in the ECQ-E6334KF?

A: Metallized polyester construction provides equivalent capacitance stability and voltage performance compared to standard polyester. Both dielectric types are suitable for general-purpose applications and maintain the specified tolerance across the operating temperature range.

Q: Are there temperature limitations when using the ECQ-E6334KF as a substitute?

A: The ECQ-E6334KF operates from -40°C to 105°C, compared to the PVC6033 range of -55°C to 125°C. Applications requiring operation outside the -40°C to 105°C window must use the original PVC6033 or identify alternative parts with extended temperature specifications.

Q: Do both parts meet current regulatory compliance standards?

A: Both the PVC6033 and ECQ-E6334KF are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the lead spacing difference and why does it matter?

A: The PVC6033 has 1.531" (38.90mm) lead spacing, while the ECQ-E6334KF has 0.886" (22.50mm) lead spacing. This difference requires PCB footprint redesign. Verify hole spacing and trace routing compatibility before implementing the substitute.
