PVC4039 Equivalent & Substitute Parts

Part Overview

The PVC4039 is a 0.39 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400VDC voltage rating. This component is classified as obsolete, making substitution with active equivalent parts necessary for ongoing design and procurement requirements. The PVC series capacitor is a through-hole radial device designed for general-purpose applications requiring polyester dielectric film construction.

Key Parameters

Substitute Part Grouping Explanation

The ECQ-E4394KF (Panasonic Electronic Components) qualifies as a direct electrical substitute for the PVC4039 based on the following matching parameters:

• Capacitance: 0.39 µF (identical)
• Tolerance: ±10% (identical)
• Voltage Rating - DC: 400V (identical)
• Voltage Rating - AC: 200V (identical)
• Dielectric Material: Polyester (same material family)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Termination: PC Pins (identical)

Both components meet ROHS3 compliance and REACH unaffected status. The substitute maintains the same electrical performance envelope for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E4394KF is suitable as an electrical substitute for the PVC4039 where:

• Capacitance, tolerance, and voltage ratings match application requirements exactly
• Through-hole radial mounting configuration is compatible with PCB layout
• Operating temperature range of -40°C to 105°C (ECQ-E4394KF) covers the application environment
• Both components maintain ROHS3 compliance and REACH unaffected certification status
• The substitute is an active product with current inventory availability

The reduced lead spacing on the ECQ-E4394KF (15.00mm versus 34.10mm) and smaller physical dimensions require PCB layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for the ECQ-E4394KF to substitute the PVC4039?

A: Capacitance (0.39 µF), tolerance (±10%), DC voltage rating (400V), AC voltage rating (200V), and dielectric material (polyester) must remain identical. These parameters determine circuit performance and reliability.

Q: Are there physical compatibility concerns when using ECQ-E4394KF?

A: Yes. The ECQ-E4394KF has a significantly reduced lead spacing (15.00mm) compared to the PVC4039 (34.10mm), and smaller overall dimensions. PCB footprint verification is required before substitution.

Q: What is the operating temperature difference between these components?

A: The PVC4039 operates from -55°C to 125°C, while the ECQ-E4394KF operates from -40°C to 105°C. Applications requiring extended low-temperature performance below -40°C are limited to the original PVC4039.

Q: Do both components meet current environmental compliance standards?

A: Yes. Both the PVC4039 and ECQ-E4394KF are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
