PVC12222 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC12222 is a 2200 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1.2 kV DC operation with polypropylene dielectric material. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The radial through-hole configuration and general-purpose application profile make this capacitor suitable for replacement with functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC12222 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 2200 pF (exact match required)
• Voltage rating: Substitute must equal or exceed 1200V DC
• Dielectric material: Polypropylene (PP) composition
• Operating temperature range: Must accommodate -55°C ~ 105°C or equivalent operational envelope

Mechanical Equivalence Criteria:

• Mounting type: Through-hole radial configuration
• Termination style: PC pins
• Lead spacing: Compatible with 0.969" (24.60mm) pitch or PCB layout accommodation

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status maintained

The ECW-H12222JV from Panasonic Electronic Components satisfies these substitution parameters with the following considerations: identical capacitance value, higher voltage rating (1.25 kV DC), tighter tolerance (±5%), and active product status.

Engineering Selection Recommendations

Primary Substitute: ECW-H12222JV (Panasonic Electronic Components)

The ECW-H12222JV qualifies as a functional equivalent based on the following engineering criteria:

1. Electrical Compatibility: Identical 2200 pF capacitance with superior voltage rating (1.25 kV DC vs. 1.2 kV DC) and tighter tolerance specification (±5% vs. ±10%) provide enhanced performance margin and precision.

2. Dielectric Composition: Polypropylene (PP) metallized construction maintains the same dielectric family, ensuring comparable frequency response and stability characteristics.

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

4. Product Status: The ECW-H12222JV is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete PVC12222.

5. Mechanical Consideration: Lead spacing differs (15.00mm vs. 24.60mm). PCB layout modification is required for direct substitution. Physical dimensions are substantially smaller (18.00mm L x 6.50mm W vs. 10.70mm Dia x 31.80mm L), necessitating board redesign evaluation.

6. Temperature Range: The original PVC12222 supports extended low-temperature operation (-55°C vs. -40°C). Applications requiring sub-40°C operation require design review.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H12222JV directly replace the PVC12222 without PCB modification?

A: No. The lead spacing differs significantly (15.00mm vs. 24.60mm), and physical dimensions are substantially different. PCB layout modification is required for mechanical mounting. Electrical functionality is compatible; mechanical integration requires redesign.

Q: What is the impact of the tighter tolerance (±5% vs. ±10%) on circuit performance?

A: The ECW-H12222JV tolerance of ±5% provides improved capacitance precision compared to the original ±10% specification. This reduces circuit parameter variation and improves performance consistency. No negative impact occurs; performance is enhanced.

Q: Is the lower AC voltage rating (354V vs. 475V) a limitation?

A: The AC voltage rating difference reflects different test standards and dielectric construction. The DC voltage rating (1.25 kV) exceeds the original (1.2 kV), providing superior voltage margin. AC rating applicability depends on specific circuit requirements. Verify AC voltage stress in your application.

Q: Why is the operating temperature range narrower (-40°C vs. -55°C)?

A: The ECW-H12222JV minimum operating temperature is -40°C compared to -55°C for the PVC12222. Applications requiring operation below -40°C must retain the original component or identify alternative substitutes with extended low-temperature ratings.

Q: Are both components RoHS3 compliant?

A: Yes. Both the PVC12222 and ECW-H12222JV are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of metallized polypropylene in the ECW-H12222JV?

A: Metallized polypropylene construction provides self-healing properties and compact form factor compared to film-only construction. This is a standard industry advancement and does not affect substitution compatibility for general-purpose applications.
