PVC2X218 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC2X218 is a 1800 pF polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 2000V DC operation with ±10% capacitance tolerance. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and procurement planning.

Film capacitors in this specification range are used in general-purpose applications requiring high voltage DC performance and stable capacitance characteristics across the operating temperature range of -55°C to 105°C. The radial through-hole mounting configuration and PC pin termination are standard for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC2X218 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 1800 pF (exact match required)
• Dielectric material: Polypropylene (PP) for equivalent electrical performance
• Mounting type: Through Hole radial configuration
• Termination style: PC Pins for PCB compatibility

Voltage Rating Consideration: The PVC2X218 operates at 2000V DC. Substitute parts must maintain voltage ratings sufficient for the application circuit. A substitute with lower voltage rating (1600V DC) is acceptable only when the circuit design does not require the full 2000V margin.

Tolerance and Temperature Range: The ±10% tolerance of the PVC2X218 establishes the acceptable capacitance variance. Substitute parts with equal or tighter tolerance (±5%) are functionally compatible. Operating temperature ranges must encompass or match the original specification to ensure performance stability.

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

Engineering Selection Recommendations

ECW-H16182JV (Panasonic) as Substitute:

The ECW-H16182JV meets the core electrical requirements of capacitance (1800 pF) and dielectric material (polypropylene). Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Voltage Rating Differential: The substitute operates at 1600V DC versus the original 2000V DC specification. This 400V reduction in voltage rating must be evaluated against the actual circuit operating voltage. If the circuit design includes sufficient safety margin and does not approach 1600V stress levels, the substitute is electrically viable.

Temperature Range Limitation: The substitute's minimum operating temperature is -40°C, compared to the original -55°C specification. Applications requiring operation below -40°C are not suitable for this substitute.

Physical Form Factor: The substitute exhibits a different package geometry (18.00mm × 7.00mm footprint with 15.00mm lead spacing) compared to the original (9.70mm diameter with 24.60mm lead spacing). PCB layout verification is required to confirm mechanical compatibility and lead hole alignment.

Tolerance Improvement: The substitute's ±5% tolerance is tighter than the original ±10%, providing improved capacitance stability if the circuit design benefits from reduced variance.

Active Production Status: The ECW-H16182JV is in active production with 2915 units in stock, providing supply continuity for the obsolete PVC2X218.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H16182JV directly replace the PVC2X218 without circuit modification?

A: Direct replacement requires verification of three factors: (1) circuit operating voltage does not exceed 1600V DC, (2) minimum operating temperature requirement does not fall below -40°C, and (3) PCB layout accommodates the different lead spacing (15.00mm versus 24.60mm) and package dimensions.

Q: What is the significance of the metallized polypropylene construction in the substitute?

A: Metallized polypropylene provides self-healing characteristics in the dielectric layer. Both the original and substitute use polypropylene as the base dielectric material, maintaining equivalent electrical performance for general-purpose applications.

Q: How does the ±5% tolerance of the substitute compare to the ±10% tolerance of the original?

A: The ±5% tolerance is tighter, meaning the substitute maintains capacitance value within a narrower range. This is functionally compatible with circuits designed for the original ±10% specification.

Q: Are there physical space constraints with the substitute component?

A: Yes. The substitute has a different form factor (18.00mm length × 7.00mm width versus 9.70mm diameter) and different lead spacing (15.00mm versus 24.60mm). PCB layout must be verified to confirm the component fits within available space and lead holes align correctly.

Q: What compliance certifications apply to both components?

A: Both the PVC2X218 and ECW-H16182JV are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance for applications subject to these standards.

Q: Is the lower voltage rating of the substitute a limiting factor?

A: The 1600V DC rating of the substitute is lower than the original 2000V DC specification. Substitution is appropriate only when the circuit design operates below 1600V and includes adequate safety margin. High-voltage applications requiring the full 2000V rating cannot use this substitute.
