PVC2X239 Equivalent & Substitute Parts

Part Overview

The PVC2X239 is a 3900 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 2000V DC voltage rating and polypropylene dielectric. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design support and procurement requirements. The radial through-hole configuration and ±10% tolerance make this capacitor suitable for general-purpose applications requiring high-voltage film capacitor performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC2X239 is based on the following critical parameters that must be maintained or exceeded:

Mandatory Matching Parameters:

• Capacitance value: 3900 pF
• DC voltage rating: minimum 2000V
• Dielectric material: Polypropylene (PP)
• Mounting type: Through Hole
• Package configuration: Radial
• Termination style: PC Pins

Allowable Variations:

• Tolerance may be tighter (lower percentage acceptable)
• AC voltage rating may be higher
• Operating temperature range may be extended
• Physical dimensions may differ within PCB layout constraints
• Lead spacing may differ if board layout permits

The B32672L8392J000 from EPCOS - TDK Electronics meets all mandatory parameters while providing improved tolerance (±5% versus ±10%) and extended temperature range (-55°C ~ 110°C versus -55°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The B32672L8392J000 is a direct functional substitute for the obsolete PVC2X239. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The substitute part provides the following advantages:

• Active Product Status: The B32672L8392J000 is an active product with 10,791 units in stock, ensuring long-term availability compared to the obsolete PVC2X239.
• Improved Tolerance: The ±5% tolerance specification provides tighter capacitance control than the original ±10% tolerance.
• Extended Temperature Range: Operating temperature extends to 110°C, providing additional thermal margin beyond the original 105°C specification.
• Higher AC Voltage Rating: The 700V AC rating exceeds the original 500V AC specification.
• Metallized Dielectric: The metallized polypropylene construction is suitable for high-frequency and switching applications.

Physical dimensions differ between the two parts. The substitute is more compact (18.00mm x 5.00mm versus 11.90mm x 31.80mm), which may provide layout advantages. Lead spacing remains identical at 0.591" (15.00mm), supporting direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B32672L8392J000 be used as a direct replacement for the PVC2X239?

A: Yes. Both components share identical capacitance (3900 pF), DC voltage rating (2000V), dielectric material (polypropylene), mounting type (through hole), package configuration (radial), and lead spacing (0.591"). The substitute meets or exceeds all critical electrical parameters.

Q: What is the difference between standard and metallized polypropylene film?

A: The B32672L8392J000 uses metallized polypropylene, where a thin metal layer is deposited on the dielectric surface. This construction is standard for high-frequency and switching applications. Both dielectric types maintain the same electrical properties for DC voltage rating and capacitance value.

Q: Will the physical size difference affect PCB layout?

A: The substitute part is more compact (18.00mm x 5.00mm versus 11.90mm x 31.80mm). Lead spacing is identical at 0.591" (15.00mm), ensuring footprint compatibility. Physical dimensions should be verified against available PCB space, but the smaller profile typically provides layout advantages.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the PVC2X239 and B32672L8392J000 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

Q: What is the significance of the ±5% tolerance improvement?

A: The substitute part's ±5% tolerance provides tighter capacitance control compared to the original ±10% specification. This tighter tolerance reduces capacitance variation across production batches, which may improve circuit performance in applications sensitive to capacitance drift.

Q: Why is the substitute part listed as active while the original is obsolete?

A: The PVC2X239 is an older Cornell Dubilier design that has been discontinued. The B32672L8392J000 is a current EPCOS - TDK product with active manufacturing and distribution, ensuring availability for new designs and ongoing production requirements.
