PVC12112 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC12112 is a 0.012 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1200V DC operation with polypropylene dielectric material and radial through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The radial configuration and high voltage rating position this capacitor for general-purpose applications requiring reliable DC voltage withstand capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC12112 is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 0.012 µF (exact match required)
• Dielectric material: Polypropylene (PP)
• Mounting type: Through Hole Radial
• Voltage rating: DC rating must equal or exceed 1200V
• Termination: PC Pins

Secondary Compatibility Factors:

• Tolerance: ±10% or tighter acceptable
• Operating temperature range: Must encompass or match -55°C to +105°C
• Physical dimensions and lead spacing: Must accommodate existing PCB layouts
• Regulatory compliance: ROHS3 and REACH status alignment

The ECW-H12123JV from Panasonic Electronic Components meets the primary matching criteria with identical capacitance, polypropylene dielectric, radial through-hole configuration, and PC pin termination. The substitute part exceeds the DC voltage requirement (1250V vs. 1200V) and maintains ROHS3 compliance.

Engineering Selection Recommendations

ECW-H12123JV Substitution Basis:

The ECW-H12123JV qualifies as a direct substitute for the PVC12112 based on the following engineering factors:

1. Electrical Equivalence: Identical 0.012 µF capacitance with tighter ±5% tolerance provides superior performance stability compared to the original ±10% specification.

2. Voltage Compliance: The 1250V DC rating exceeds the original 1200V requirement, ensuring adequate safety margin in high-voltage applications.

3. Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

4. Availability: The substitute part is classified as Active with 15,784 units in stock, compared to the obsolete status of the original PVC12112.

5. Physical Compatibility: Radial through-hole configuration with PC pin termination ensures mechanical compatibility with existing PCB designs, though lead spacing differs (15.00mm vs. 24.60mm) and must be verified for specific board layouts.

Application Considerations:

The lower AC voltage rating (354V vs. 475V) of the substitute part requires verification for applications involving AC voltage stress. The narrower operating temperature range (-40°C to +105°C vs. -55°C to +105°C) must be confirmed for systems operating below -40°C.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H12123JV directly replace the PVC12112 without PCB modification?

A: Electrical substitution is valid. However, physical lead spacing differs (15.00mm vs. 24.60mm), requiring PCB layout verification. Direct socket replacement is not guaranteed without dimensional assessment.

Q: What is the significance of the tighter ±5% tolerance in the substitute part?

A: The ECW-H12123JV tolerance of ±5% provides narrower capacitance variation compared to the original ±10%, resulting in improved circuit performance consistency and reduced tolerance stack-up in precision applications.

Q: Is the lower AC voltage rating of the substitute part a limitation?

A: The ECW-H12123JV AC rating of 354V is lower than the original 475V. Applications involving AC voltage stress must confirm that circuit AC voltage requirements do not exceed 354V.

Q: Why does the substitute part have a narrower operating temperature range?

A: The ECW-H12123JV operates from -40°C to +105°C, compared to the original -55°C to +105°C. Systems requiring operation below -40°C must retain the original PVC12112 or identify alternative substitutes with extended low-temperature ratings.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the PVC12112 and ECW-H12123JV are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the practical advantage of the substitute part's higher DC voltage rating?

A: The 1250V DC rating of the ECW-H12123JV provides a 50V safety margin above the original 1200V specification, enhancing reliability in high-voltage DC applications and reducing stress-related degradation risk.
