PVC6118 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6118 is a 0.018 µF polyester film capacitor rated for 600V DC operation, manufactured by Cornell Dubilier Electronics (CDE) in the PVC series. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The radial through-hole configuration and general-purpose application profile support direct substitution with compatible alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete PVC6118 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.018 µF (exact match required)
• Tolerance: ±10% (matching tolerance band)
• Voltage rating: Substitute must equal or exceed 600V DC rating
• Dielectric material: Polyester composition

Mechanical Equivalence Criteria:

• Mounting type: Through hole configuration
• Package style: Radial lead arrangement
• Termination: PC pins
• Lead spacing: Compatible with 0.689" (17.50mm) pitch or smaller

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required

The ECQ-E6183KF from Panasonic Electronic Components meets all electrical and mechanical substitution criteria, with enhanced voltage rating (630V DC) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6183KF qualifies as a direct electrical substitute for the obsolete PVC6118 based on matched capacitance, tolerance, and dielectric material specifications. The substitute component provides enhanced voltage ratings (630V DC / 250V AC) relative to the original specification (600V DC / 200V AC), ensuring operation within design margins.

The ECQ-E6183KF maintains active product status with established supply availability (1876 pcs in stock), eliminating obsolescence risk associated with the PVC6118. Both components carry ROHS3 compliance and REACH unaffected certification, satisfying regulatory requirements.

Physical footprint differences exist: the ECQ-E6183KF exhibits reduced lead spacing (0.394" versus 0.689") and smaller overall dimensions (12.00mm L x 4.90mm W versus 11.40mm Dia x 22.90mm L). PCB layout verification is required to confirm mechanical compatibility in existing designs.

Operating temperature range differs: the PVC6118 supports -55°C to 125°C operation, while the ECQ-E6183KF operates within -40°C to 105°C. Applications requiring sub-zero temperatures below -40°C must evaluate alternative substitutes or retain original components.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6183KF directly replace the PVC6118 in all applications?

A: Electrical substitution is valid for applications operating within the ECQ-E6183KF temperature range (-40°C to 105°C). Physical footprint differences require PCB layout verification. Applications requiring operation below -40°C must use alternative components.

Q: What is the significance of the lead spacing difference between these parts?

A: The PVC6118 has 0.689" (17.50mm) lead spacing, while the ECQ-E6183KF has 0.394" (10.00mm) spacing. Existing PCB designs with through-hole pads spaced at 17.50mm cannot accommodate the smaller 10.00mm pitch without modification. New designs can utilize the more compact ECQ-E6183KF footprint.

Q: Does the metallized polyester dielectric in the ECQ-E6183KF affect performance compared to standard polyester?

A: Metallized polyester dielectric is electrically equivalent to standard polyester for this capacitance and voltage class. The metallization provides self-healing properties under overvoltage conditions, enhancing reliability without altering nominal electrical characteristics.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the PVC6118 and ECQ-E6183KF carry ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for industrial and commercial applications.

Q: Why is the PVC6118 classified as obsolete?

A: Obsolescence reflects discontinuation by the manufacturer (Cornell Dubilier Electronics). The ECQ-E6183KF from Panasonic maintains active product status with established supply chains, making it the preferred substitute for new designs and ongoing maintenance applications.

Q: What tolerance band applies to both capacitors?

A: Both components carry ±10% tolerance, ensuring equivalent capacitance accuracy across the specified range (0.0162 µF to 0.0198 µF).
