PVC12212 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC12212 is a 1200 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the PVC series. This radial polypropylene capacitor is rated for 1.2 kV DC and 475 V AC operation across a temperature range of -55°C to 105°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where legacy specifications must be maintained or exceeded.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC12212 is determined by the following critical parameters:

Capacitance Match: The substitute must provide 1200 pF capacitance to maintain circuit function.

Voltage Rating Compatibility: The substitute must meet or exceed the 1200V DC rating. A higher voltage rating (1600V DC) provides additional safety margin and is acceptable for substitution.

Dielectric Material: Polypropylene (PP) dielectric is maintained in the substitute to preserve electrical characteristics and frequency response.

Mounting and Package: Through-hole radial mounting with PC pin termination ensures mechanical compatibility with existing PCB layouts.

Temperature Range: The substitute operating temperature range must encompass or exceed the original -55°C to 105°C specification.

Tolerance: The substitute tolerance of ±5% is tighter than the original ±10%, providing improved capacitance accuracy without compromising compatibility.

The B32671L1122J000 from EPCOS - TDK Electronics meets all substitution criteria while offering enhanced specifications in voltage rating and temperature range.

Engineering Selection Recommendations

The B32671L1122J000 is a direct functional substitute for the obsolete PVC12212. Selection of this substitute is supported by the following factors:

Compliance and Availability: The B32671L1122J000 is an active product with high inventory availability (20,069 pcs in stock), ensuring reliable procurement for both immediate replacement and future production requirements. Both parts maintain ROHS3 compliance and REACH unaffected status.

Electrical Performance: The substitute meets all electrical requirements of the original specification. The 1600V DC rating provides a 33% safety margin above the 1200V requirement. The ±5% tolerance improves circuit accuracy compared to the original ±10% tolerance.

Thermal Capability: The extended operating temperature range (-55°C to 110°C) accommodates the original specification with an additional 5°C upper limit, supporting applications in elevated temperature environments.

Physical Compatibility: Radial through-hole mounting with PC pin termination ensures direct PCB layout compatibility. Physical dimensions differ (substitute is more compact), but this does not affect electrical function or circuit board integration.

Series Classification: The B32671L1122J000 belongs to the EPCOS B3267L MKP High Current series, designed for high-frequency switching and high pulse DV/DT applications, making it suitable for demanding circuit conditions.

Frequently Asked Questions (FAQ)

Q: Can the B32671L1122J000 be used as a direct replacement for PVC12212 in existing designs?

A: Yes. Both parts share identical capacitance (1200 pF), mounting type (through-hole radial), termination style (PC pins), and dielectric material (polypropylene). The substitute exceeds the voltage and temperature specifications of the original part.

Q: What is the difference between the physical dimensions of these two capacitors?

A: The PVC12212 measures 0.421" diameter × 1.252" length with 0.969" lead spacing. The B32671L1122J000 measures 0.512" length × 0.157" width with 0.394" lead spacing. The substitute is more compact. PCB layout modifications may be required if the original footprint was tightly constrained.

Q: Does the metallized polypropylene construction of the substitute affect circuit performance?

A: Metallized polypropylene is a standard construction method for film capacitors and maintains the electrical characteristics of polypropylene dielectric. The substitute is suitable for general purpose and high-frequency switching applications.

Q: Are there any compliance or certification differences between the original and substitute?

A: Both parts are ROHS3 compliant and REACH unaffected. The substitute carries AEC-Q200 automotive qualification, providing additional reliability assurance for demanding applications.

Q: What is the lead spacing consideration for PCB layout?

A: The original PVC12212 has 0.969" (24.60mm) lead spacing, while the B32671L1122J000 has 0.394" (10.00mm) lead spacing. PCB footprints must be verified and potentially redesigned to accommodate the substitute's narrower lead spacing.

Q: Is the tighter tolerance of the substitute (±5% vs ±10%) beneficial?

A: Yes. The ±5% tolerance of the B32671L1122J000 provides improved capacitance accuracy, which is beneficial for precision circuits where capacitance value stability is critical.
