PVC622 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC622 is a 2000 pF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600V DC operation with ±10% tolerance. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 125°C).

The PVC622 carries an Obsolete product status, indicating it is no longer in active production. Locating equivalent or substitute components is necessary for maintenance, repair, and legacy system support where original stock is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC622 is constrained by the following critical parameters:

Capacitance Equivalence: The substitute must provide 2000 pF (0.002 µF) nominal capacitance with ±10% tolerance to maintain circuit function.

Voltage Rating: The substitute must meet or exceed 600V DC rating to ensure safe operation under the original design specifications.

Dielectric Type: While the PVC622 uses polyester film, ceramic dielectrics with appropriate temperature coefficients (such as X7R) can substitute when voltage and capacitance requirements are met, provided the application does not require the specific frequency response or ESR characteristics of film capacitors.

Temperature Range: The substitute must support the full -55°C to 125°C operating window.

Mounting Configuration: The substitute must be a through-hole radial component compatible with standard PCB lead spacing and soldering processes.

Compliance: Both the main part and substitute must maintain ROHS3 compliance and REACH Unaffected status for regulatory continuity.

The identified substitute FK26X7R2J223KN000 (TDK Corporation) meets these criteria with equivalent capacitance (0.022 µF = 22000 pF nominal, which requires verification against circuit tolerance requirements), exceeds voltage rating (630V), maintains temperature range compatibility, and preserves compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Capacitance Verification Required: The FK26X7R2J223KN000 nominal capacitance (0.022 µF) differs from the PVC622 (0.002 µF) by a factor of 11. Circuit schematic review is mandatory to confirm whether this capacitance value is appropriate for the intended application. If the original design requires 2000 pF specifically, alternative substitutes with matching capacitance must be sourced.

Dielectric Transition: Substituting polyester film with ceramic X7R introduces different electrical characteristics, including frequency response and temperature stability behavior. Applications sensitive to these parameters require detailed circuit analysis.

Product Status Consideration: The FK26X7R2J223KN000 carries "Not For New Designs" status, indicating limited future availability. For long-term supply chain planning, additional alternatives should be evaluated.

Compliance Continuity: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the FK26X7R2J223KN000 directly replace the PVC622 in any circuit?

A: Direct replacement is not guaranteed due to the significant capacitance difference (0.022 µF vs. 0.002 µF). The substitute is suitable only if circuit analysis confirms the higher capacitance value does not degrade performance or violate design specifications.

Q: What is the impact of switching from polyester film to ceramic X7R dielectric?

A: Ceramic X7R capacitors exhibit different frequency response, temperature coefficient behavior, and ESR characteristics compared to polyester film. Applications requiring specific frequency filtering or low-loss characteristics may require additional evaluation.

Q: Are both components suitable for high-voltage applications?

A: Yes. Both the PVC622 (600V DC) and FK26X7R2J223KN000 (630V) exceed typical high-voltage thresholds and maintain adequate safety margins for general-purpose circuits operating within their rated voltage ranges.

Q: What is the lead spacing compatibility between these components?

A: The PVC622 specifies 0.500" (12.70mm) lead spacing, while the FK26X7R2J223KN000 specifies 0.197" (5.00mm) lead spacing. PCB layout modification is required if substituting these components.

Q: Do both components meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH Unaffected, ensuring compatibility with current environmental and safety regulations.

Q: Is the FK26X7R2J223KN000 recommended for new circuit designs?

A: No. The FK26X7R2J223KN000 carries "Not For New Designs" status. For new applications, alternative components with active production status should be prioritized to ensure long-term supply chain stability.
