PVC6127 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6127 is a 0.027 µF polyester film capacitor rated for 600V DC operation, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The radial through-hole configuration and general-purpose application profile make this capacitor suitable for replacement with modern active alternatives that maintain electrical and mechanical compatibility within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC6127 is based on the following electrical and mechanical criteria:

Electrical Compatibility Requirements:

• Capacitance value must equal 0.027 µF
• DC voltage rating must be ≥600V
• AC voltage rating must be ≥200V
• Tolerance must be ≤±10% (equal or tighter)
• Dielectric material must be compatible with polyester film applications

Mechanical Compatibility Requirements:

• Mounting type must be through-hole radial
• Lead spacing must accommodate 0.969" (24.60mm) PCB hole patterns
• Physical dimensions must fit within existing PCB layouts
• Termination must be PC pins

Regulatory Compliance:

• RoHS3 compliance required
• REACH compliance status must be unaffected or compliant

The identified substitute ECW-F6273JL meets these criteria with the following considerations: it maintains the 0.027 µF capacitance value, exceeds the voltage rating (630V DC vs. 600V DC), provides tighter tolerance (±5% vs. ±10%), and maintains through-hole radial configuration. However, the lead spacing differs (0.394" vs. 0.969"), requiring PCB layout verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The PVC6127 is classified as obsolete, making ECW-F6273JL the identified active substitute from Panasonic Electronic Components. This substitute maintains production status and supply chain availability.

Electrical Suitability: The ECW-F6273JL satisfies all critical electrical parameters: capacitance value matches exactly at 0.027 µF, DC voltage rating exceeds the requirement (630V vs. 600V), and AC voltage rating exceeds the requirement (223V vs. 200V). The substitute's tighter tolerance (±5% vs. ±10%) provides improved circuit performance.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Physical Integration Limitation: The lead spacing differs significantly (0.394" vs. 0.969"), requiring PCB layout modification. The substitute component is physically smaller, necessitating either PCB redesign or use of adapter solutions for direct replacement in existing assemblies.

Temperature Range Consideration: The substitute's operating temperature range (-40°C to 105°C) is narrower than the original (-55°C to 125°C). Applications requiring operation below -40°C or above 105°C require alternative solutions.

Dielectric Material Difference: The substitute uses polypropylene (PP) metallized film instead of polyester. This material change affects frequency response characteristics and may impact performance in high-frequency or switching applications. Circuit-level validation is required for applications sensitive to dielectric properties.

Frequently Asked Questions (FAQ)

Q: Can ECW-F6273JL be used as a direct drop-in replacement for PVC6127?

A: Electrical substitution is feasible based on capacitance, voltage rating, and tolerance parameters. However, mechanical substitution requires PCB modification due to different lead spacing (0.394" vs. 0.969"). Direct PCB mounting without layout changes is not possible.

Q: What is the significance of the different dielectric materials (polyester vs. polypropylene)?

A: Polyester and polypropylene film capacitors exhibit different frequency response, temperature stability, and ESR characteristics. Polypropylene typically offers lower ESR and better high-frequency performance. Circuit-level testing is necessary to confirm functional equivalence in frequency-dependent applications.

Q: Does the tighter tolerance of ECW-F6273JL (±5% vs. ±10%) provide any advantage?

A: Yes. The ±5% tolerance of ECW-F6273JL provides improved capacitance accuracy compared to the ±10% tolerance of PVC6127. This results in tighter circuit performance and reduced tolerance stack-up in multi-component designs.

Q: Are there temperature range limitations when substituting with ECW-F6273JL?

A: Yes. The ECW-F6273JL operating range (-40°C to 105°C) is narrower than PVC6127 (-55°C to 125°C). Applications requiring operation below -40°C or above 105°C cannot use this substitute without additional thermal management or alternative component selection.

Q: What compliance certifications apply to both components?

A: Both PVC6127 and ECW-F6273JL are ROHS3 compliant and REACH unaffected, satisfying standard regulatory requirements for electronic component substitution in regulated industries.

Q: How does the voltage rating difference affect circuit design?

A: ECW-F6273JL exceeds both AC and DC voltage ratings of PVC6127 (630V DC vs. 600V DC; 223V AC vs. 200V AC). This provides additional safety margin and allows operation in higher voltage applications without derating.

Q: What inventory status should be considered for procurement?

A: PVC6127 has 1158 pieces in stock as new original inventory. ECW-F6273JL has 1423 pieces in stock. The substitute offers superior supply chain availability due to active product status versus obsolete classification.
