PVC625 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC625 is a 5000 pF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600V DC operation with ±10% tolerance. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing maintenance and repair applications. The radial through-hole configuration and general-purpose design make it suitable for legacy electronic equipment requiring film capacitor technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC625 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must match or fall within the ±10% tolerance band (4500 pF to 5500 pF)
• Voltage rating must equal or exceed 600V DC to maintain circuit safety margins
• Tolerance specification must be ±10% or tighter

Physical Compatibility:

• Mounting type must be through-hole radial configuration
• Lead spacing must accommodate 0.500" (12.70mm) PCB hole patterns
• Operating temperature range must span -55°C to 125°C minimum

Compliance Requirements:

• RoHS3 compliance required for modern manufacturing standards
• REACH unaffected status acceptable

The substitute part FK26X7R2J153KN000 (TDK Corporation) presents a capacitance value of 0.015 µF (15000 pF), which exceeds the PVC625 specification by a factor of three. This represents a different capacitance class and does not meet the strict substitution criteria for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Based on provided specifications and compliance data:

PVC625 Direct Substitution Status: No equivalent substitute meeting all electrical parameters has been identified in the provided dataset. The FK26X7R2J153KN000 differs fundamentally in capacitance value (15000 pF versus 5000 pF) and dielectric technology (ceramic X7R versus polyester), making it unsuitable for direct replacement in circuits designed for the PVC625 specification.

Compliance Considerations: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying modern regulatory requirements. The PVC625 remains available in inventory (982 units), providing continued access to the original specification for legacy system support.

Product Status Impact: The PVC625 obsolete status indicates CDE has discontinued production. For new equipment designs, alternative capacitor families with matching 5000 pF capacitance, 600V rating, and polyester dielectric should be sourced from active manufacturers.

Frequently Asked Questions (FAQ)

Q: Can FK26X7R2J153KN000 replace PVC625 in my circuit?

A: No. The FK26X7R2J153KN000 has a capacitance of 15000 pF, which is three times the PVC625 specification of 5000 pF. Additionally, it uses ceramic X7R dielectric technology rather than polyester. These differences make it electrically incompatible for direct substitution.

Q: What makes capacitance value critical for substitution?

A: Capacitance determines circuit frequency response, filtering characteristics, and timing functions. A 15000 pF capacitor will produce significantly different circuit behavior than a 5000 pF capacitor, potentially causing circuit malfunction or performance degradation.

Q: Are the physical dimensions compatible?

A: Both components use through-hole radial mounting with compatible lead spacing (0.500" for PVC625, 0.197" for FK26X7R2J153KN000). However, physical compatibility alone does not justify substitution when electrical parameters diverge.

Q: Why is dielectric material important?

A: Polyester and ceramic dielectrics exhibit different temperature coefficients, frequency response, and aging characteristics. Polyester film capacitors provide superior stability for general-purpose applications, while ceramic capacitors offer different performance trade-offs. Substitution between technologies requires circuit-level analysis.

Q: What should I do if PVC625 inventory is depleted?

A: Source alternative 5000 pF polyester film capacitors rated for 600V DC from active manufacturers. Verify capacitance tolerance (±10%), operating temperature range (-55°C to 125°C), and through-hole radial package compatibility before selection.

Q: Is the voltage rating difference significant?

A: The FK26X7R2J153KN000 630V rating exceeds the PVC625 600V requirement. However, voltage rating alone does not compensate for the three-fold capacitance mismatch, which is the primary incompatibility.
