PVC12122 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC12122 is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1200V DC and 475V AC operation. This radial polypropylene capacitor is designed for general-purpose applications with through-hole mounting. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, maintenance, and new design implementations where this specification remains applicable.

Substitute Part Grouping Explanation

Substitution of the PVC12122 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

Capacitance value: 0.022 µF (exact match required)
Voltage rating: DC rating must equal or exceed 1200V; AC rating must equal or exceed 475V
Dielectric material: Polypropylene (PP) or metallized polypropylene
Mounting type: Through hole radial configuration
Termination style: PC pins

Secondary Compatibility Factors:

Tolerance: ±10% or tighter tolerance acceptable
Operating temperature range: Must support -55°C minimum and 105°C maximum
RoHS and REACH compliance status

The substitute part B32652A7223J000 meets these criteria with a higher voltage rating (1250V DC, 500V AC), tighter tolerance (±5%), and active product status, making it a valid functional equivalent for the obsolete PVC12122.

Engineering Selection Recommendations

B32652A7223J000 as Primary Substitute:

The B32652A7223J000 from EPCOS - TDK Electronics is a direct functional substitute for the PVC12122. This assessment is based on the following engineering factors:

Electrical Equivalence: Both capacitors share identical capacitance (0.022 µF) and polypropylene dielectric material. The substitute's voltage ratings (1250V DC, 500V AC) exceed the original specification, providing additional safety margin in high-voltage applications.
Tolerance Improvement: The B32652A7223J000 offers ±5% tolerance compared to the PVC12122's ±10%, resulting in tighter capacitance accuracy for precision circuit requirements.
Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and deployment standards.
Product Availability: The substitute is classified as active with 10,000 units in stock, providing reliable long-term supply compared to the obsolete PVC12122.
Temperature Consideration: The substitute operates to 100°C maximum versus the original's 105°C. Applications requiring sustained operation above 100°C require verification against specific circuit thermal profiles.
Physical Dimensions: The substitute features a more compact radial package (18.00mm L x 8.50mm W x 14.50mm H) compared to the original (15.20mm Dia x 41.90mm L), requiring PCB layout verification for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can B32652A7223J000 directly replace PVC12122 in existing circuits?

A: Yes, the B32652A7223J000 is electrically equivalent for the specified 0.022 µF, 1200V DC application. Physical dimensions differ; verify PCB footprint compatibility and lead spacing (15.00mm for substitute versus 34.10mm for original) before implementation.

Q: What is the significance of the voltage rating difference?

A: The substitute's higher voltage rating (1250V DC versus 1200V DC) provides additional safety margin and is acceptable for direct substitution. No circuit redesign is required; the component will operate within its rated envelope.

Q: Does the ±5% tolerance of the substitute affect circuit performance?

A: The tighter tolerance of the substitute improves capacitance accuracy. For applications sensitive to capacitance variation, this represents an enhancement over the original ±10% specification.

Q: Are there physical mounting differences?

A: Yes. The substitute uses a compact radial package (18.00mm x 8.50mm footprint, 15.00mm lead spacing) versus the original's larger radial format (15.20mm diameter, 34.10mm lead spacing). PCB layout and mechanical clearance must be verified.

Q: What is the maximum operating temperature for the substitute?

A: The B32652A7223J000 operates to 100°C maximum, compared to the original's 105°C. For applications requiring sustained operation above 100°C, thermal analysis of the specific circuit is required to confirm suitability.

Q: Are both parts RoHS compliant?

A: Yes, both the PVC12122 and B32652A7223J000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What applications are suitable for this substitute?

A: The B32652A7223J000 is rated for automotive, DC link, DC filtering, high pulse DV/DT, and snubber applications. It carries AEC-Q200 automotive qualification, making it suitable for automotive and industrial high-reliability environments.
