PVC2X122 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC2X122 is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 2000V DC voltage rating and polypropylene dielectric. This component is classified as Obsolete in current product lines. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and redesign applications where this capacitor is specified in legacy designs.

Substitute Part Grouping Explanation

Substitute parts for the PVC2X122 must satisfy the following criteria based on provided specifications:

Mandatory Matching Parameters:

• Capacitance value: 0.022 µF (exact match required)
• Voltage Rating - DC: 2000V minimum (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP) or metallized polypropylene
• Mounting Type: Through Hole Radial configuration
• Termination: PC Pins for soldering compatibility

Acceptable Variation Parameters:

• Tolerance: ±5% to ±10% (tighter tolerance acceptable)
• Voltage Rating - AC: 500V or higher
• Operating Temperature: -55°C minimum to 105°C minimum (extended range acceptable)
• Lead Spacing: Physical PCB layout must accommodate the substitute footprint

The B32672L8223J000 qualifies as a substitute based on matching capacitance, DC voltage rating, dielectric material, mounting type, and termination method. Differences in physical dimensions and lead spacing require PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The B32672L8223J000 provides electrical equivalence to the PVC2X122 across all critical parameters: identical capacitance (0.022 µF), matching DC voltage rating (2000V), and compatible polypropylene dielectric material. The substitute's tighter tolerance (±5% versus ±10%) and higher AC voltage rating (700V versus 500V) present no functional disadvantage in circuit operation.

Physical and Mechanical Considerations: The substitute part exhibits significantly different physical dimensions and lead spacing. The PVC2X122 features a larger radial package (0.728" diameter, 1.650" length, 34.10mm lead spacing), while the B32672L8223J000 is a compact metallized film capacitor (18.00mm x 9.00mm footprint, 15.00mm lead spacing). PCB layout modification is required for substitution; direct pin-for-pin replacement is not possible without redesign.

Compliance and Availability: Both parts maintain ROHS3 compliance and REACH unaffected status. The PVC2X122 is obsolete with limited inventory (949 pieces), while the B32672L8223J000 is active production with substantial availability (8610 pieces). For new designs or long-term supply assurance, the active substitute is preferable.

Application Context: The B32672L8223J000 is specified for high frequency, switching, and high pulse DV/DT applications, indicating suitability for demanding electrical environments. The original PVC2X122 is designated for general purpose applications. Substitution is appropriate when the circuit can accommodate the different physical form factor and the application requirements align with or are less stringent than the substitute's rated performance.

Frequently Asked Questions (FAQ)

Q: Can the B32672L8223J000 be used as a direct replacement for the PVC2X122 without PCB modification?

A: No. While both parts are electrically equivalent (0.022 µF, 2000V DC, polypropylene dielectric), they have different physical dimensions and lead spacing. The PVC2X122 uses 34.10mm lead spacing in a larger radial package, while the B32672L8223J000 uses 15.00mm lead spacing in a compact form factor. PCB layout redesign is required.

Q: What are the critical parameters that must match for substitution?

A: Capacitance value (0.022 µF exact), DC voltage rating (2000V minimum), dielectric material (polypropylene), mounting type (through hole radial), and termination method (PC pins) must match or be compatible. Tolerance, AC voltage rating, and operating temperature range may exceed the original specification without causing functional issues.

Q: Is the B32672L8223J000 suitable for the same applications as the PVC2X122?

A: The B32672L8223J000 is rated for high frequency, switching, and high pulse DV/DT applications, which encompasses general purpose use. The substitute is suitable for applications where the PVC2X122 was used, provided the physical form factor can be accommodated in the circuit design.

Q: What compliance certifications apply to both parts?

A: Both the PVC2X122 and B32672L8223J000 are ROHS3 compliant and REACH unaffected. No additional compliance barriers exist for substitution from a regulatory standpoint.

Q: Why is the B32672L8223J000 described as metallized polypropylene while the PVC2X122 is standard polypropylene?

A: Metallized polypropylene film capacitors have a thin metal coating applied to the dielectric, which provides advantages in compact packaging and performance characteristics. Both material variants are within the polypropylene dielectric class and are electrically compatible for this application.

Q: What is the lead spacing difference and why does it matter?

A: The PVC2X122 has 34.10mm lead spacing; the B32672L8223J000 has 15.00mm lead spacing. Lead spacing determines the PCB hole pattern and component footprint. Different spacing requires PCB redesign to accommodate the substitute part's physical layout.

Q: Is the substitute part currently available?

A: Yes. The B32672L8223J000 is active production with 8610 pieces in stock, compared to the obsolete PVC2X122 with limited inventory (949 pieces). The substitute offers superior long-term supply assurance.
