PVC6268 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6268 is a 6800 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the PVC series. This radial through-hole component features polyester dielectric construction with a 600V DC voltage rating and ±10% capacitance tolerance. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVC6268 are identified based on the following electrical and mechanical compatibility criteria:

Primary Matching Criteria:

• Capacitance value of 6800 pF (exact match required)
• DC voltage rating of 630V or higher (exceeds 600V minimum requirement)
• Radial through-hole mounting configuration
• Operating temperature range of -55°C minimum and 105°C or higher maximum
• RoHS3 compliance for regulatory alignment

Acceptable Parameter Variations:

• Tolerance tighter than ±10% (±5% is acceptable)
• Dielectric material substitution from polyester to polypropylene metallized construction, provided electrical performance remains equivalent
• Lead spacing differences within PCB layout accommodation limits

Non-Negotiable Parameters:

• Capacitance value must be 6800 pF
• Voltage rating must not fall below 600V DC
• Mounting type must remain through-hole radial
• RoHS compliance status must be maintained

Engineering Selection Recommendations

B32621A6682J000 Substitution Assessment:

The B32621A6682J000 from EPCOS - TDK Electronics meets the core electrical requirements for substitution: identical 6800 pF capacitance, higher 630V DC voltage rating, and tighter ±5% tolerance. Both components maintain ROHS3 compliance and RoHS3 compliance status.

Critical Considerations:

1. Lead Spacing Incompatibility: The substitute part has 0.394" (10.00mm) lead spacing compared to the original 0.500" (12.70mm). This difference prevents direct pin-for-pin replacement on existing PCBs designed for the PVC6268. PCB modification or adapter solutions are required.

2. Physical Dimensions: The substitute exhibits a more compact profile (0.512" L x 0.157" W versus 0.402" Dia x 0.701" L). Verify clearance in the target application before implementation.

3. Operating Temperature Maximum: The substitute operates to 105°C maximum versus the original 125°C. Applications requiring operation above 105°C are not suitable for this substitute.

4. Dielectric Material Change: Substitution from polyester to polypropylene metallized construction alters frequency response and ESR characteristics. Applications sensitive to these parameters require electrical performance validation.

5. Product Status: The substitute is active production, ensuring long-term availability compared to the obsolete PVC6268.

Frequently Asked Questions (FAQ)

Q: Can the B32621A6682J000 be used as a direct replacement for the PVC6268 without PCB modification?

A: No. The lead spacing differs (0.394" versus 0.500"), preventing direct insertion into existing PVC6268 footprints. PCB rework or adapter solutions are necessary.

Q: Does the higher voltage rating of the substitute (630V versus 600V) create any compatibility issues?

A: No. Higher voltage rating provides additional safety margin and is acceptable for applications designed for 600V operation.

Q: What is the impact of the tighter tolerance (±5% versus ±10%) on circuit performance?

A: Tighter tolerance improves capacitance accuracy and reduces circuit parameter variation. This is beneficial for applications requiring precise capacitance values.

Q: Is the operating temperature range difference significant?

A: The substitute maximum of 105°C versus the original 125°C represents a 20°C reduction. Applications operating continuously above 105°C are not suitable for this substitute. Verify your application's maximum operating temperature requirement.

Q: How does the dielectric material change from polyester to polypropylene affect performance?

A: Polypropylene metallized construction typically offers lower ESR, better frequency response, and higher pulse capability compared to polyester. For general purpose applications, this substitution is acceptable. Applications with specific frequency or pulse requirements require electrical performance validation.

Q: Is the B32621A6682J000 available in sufficient quantity for production use?

A: Yes. The substitute is listed as active production with 3019 pieces in stock, ensuring availability compared to the obsolete PVC6268.

Q: Are both parts RoHS compliant?

A: Yes. Both the PVC6268 and B32621A6682J000 are ROHS3 compliant, maintaining regulatory compliance in substitution.
