PVC6122 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6122 is a 0.022 µF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600V DC operation with ±10% tolerance. This component is classified as Obsolete and is no longer in active production. Due to its discontinued status, identifying equivalent substitute parts is essential for system maintenance, repair, and redesign applications where this capacitor is specified in legacy circuits.

The PVC6122 serves general-purpose filtering and coupling applications in electronic equipment requiring high voltage DC operation. Substitute parts must maintain electrical compatibility across capacitance, voltage rating, tolerance, and dielectric properties while accommodating potential differences in physical dimensions and lead spacing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVC6122 are identified based on the following electrical and mechanical compatibility criteria:

Electrical Compatibility Requirements:

• Capacitance value: 0.022 µF (exact match required)
• Voltage rating: Minimum 600V DC (equal or higher acceptable)
• Tolerance: ±10% or tighter
• Dielectric material: Polyester or metallized polyester film
• Operating temperature range: Must encompass or exceed -55°C to 125°C

Mechanical Compatibility Considerations:

• Mounting type: Through-hole radial configuration
• Lead spacing: 0.689" (17.50mm) preferred for direct PCB compatibility; alternative spacing requires layout verification
• Package style: Radial cylindrical form factor
• Termination: PC pins (standard for radial film capacitors)

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• REACH compliance status: Unaffected
• ECCN classification: EAR99

The ECQ-E6223KF from Panasonic Electronic Components meets all electrical requirements and maintains RoHS3 compliance. Physical dimensions differ, requiring PCB layout assessment before implementation.

Engineering Selection Recommendations

Primary Substitute: ECQ-E6223KF (Panasonic Electronic Components)

The ECQ-E6223KF qualifies as an electrical equivalent to the PVC6122 based on matching capacitance (0.022 µF), tolerance (±10%), and exceeding the minimum voltage requirement (630V DC vs. 600V DC). Both components utilize polyester dielectric materials and maintain ROHS3 compliance.

Selection Criteria:

1. Electrical Compatibility: The ECQ-E6223KF meets or exceeds all electrical specifications. The higher voltage rating (630V vs. 600V) and AC rating (250V vs. 200V) provide additional safety margin in the application circuit.

2. Dielectric Performance: The metallized polyester construction of the ECQ-E6223KF offers equivalent or superior performance compared to standard polyester film, with improved volumetric efficiency and self-healing characteristics.

3. Temperature Range Limitation: The ECQ-E6223KF operating range (-40°C to 105°C) is narrower than the PVC6122 (-55°C to 125°C). Applications requiring operation below -40°C or above 105°C must verify performance or identify alternative substitutes.

4. Physical Integration: The ECQ-E6223KF has significantly different dimensions and lead spacing (0.394" vs. 0.689"). Direct PCB substitution without layout modification is not possible. PCB redesign or adapter solutions are required.

5. Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

6. Availability: The ECQ-E6223KF is in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete PVC6122.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6223KF be used as a direct drop-in replacement for the PVC6122?

A: No. While electrically compatible, the ECQ-E6223KF has different lead spacing (0.394" vs. 0.689") and physical dimensions. PCB modification or custom adapter solutions are required for installation.

Q: What is the significance of the higher voltage rating on the ECQ-E6223KF?

A: The 630V DC rating on the ECQ-E6223KF exceeds the 600V requirement of the PVC6122, providing additional safety margin and derating capability. This is acceptable and does not negatively impact circuit performance.

Q: Does the metallized polyester dielectric of the ECQ-E6223KF affect circuit behavior?

A: Metallized polyester film provides equivalent electrical performance to standard polyester film for this capacitance and voltage class. The metallized construction offers self-healing properties that can improve reliability in certain fault conditions.

Q: Are there temperature-related limitations when substituting the ECQ-E6223KF?

A: Yes. The ECQ-E6223KF operating range (-40°C to 105°C) is narrower than the PVC6122 (-55°C to 125°C). Applications requiring operation at temperatures below -40°C or above 105°C must verify performance specifications or identify alternative parts.

Q: What compliance certifications apply to both parts?

A: Both the PVC6122 and ECQ-E6223KF are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification for export control purposes.

Q: How does the more compact size of the ECQ-E6223KF affect installation?

A: The smaller physical dimensions of the ECQ-E6223KF (12.00mm x 5.30mm x 11.50mm vs. 11.40mm x 22.90mm) provide space advantages but require verification of clearance in the target enclosure and confirmation that lead spacing accommodates the PCB layout.

Q: Is the ±10% tolerance specification identical between both parts?

A: Yes. Both the PVC6122 and ECQ-E6223KF maintain ±10% capacitance tolerance, ensuring equivalent circuit performance within the specified tolerance band.
