PVC114 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC114 is a 0.04 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 100V DC voltage rating and ±10% tolerance. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing applications requiring through-hole radial film capacitors with polyester dielectric material.

The PVC114 operates across a temperature range of -55°C to 125°C and is designed for general-purpose applications. Due to its obsolete status, sourcing alternatives from active product lines is essential for system continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the PVC114 is determined by the following critical parameters:

Electrical Compatibility:

Capacitance value within ±10% tolerance band (0.036 µF to 0.044 µF nominal range)
Voltage rating equal to or exceeding 100V DC
Tolerance specification of ±10% or tighter

Physical & Mechanical Compatibility:

Through-hole radial mounting configuration
PC pin termination
Operating temperature range of -55°C to 125°C or broader

Regulatory & Environmental Compliance:

ROHS3 compliance
REACH unaffected status
Polyester or equivalent polyester-based dielectric material

The substitute part B32529C1473K000 meets these criteria with a capacitance of 0.047 µF (within tolerance band), 100V DC rating, polyester dielectric, and identical operating temperature range. Physical dimensions differ due to modern manufacturing standards, but electrical performance remains equivalent for general-purpose applications.

Engineering Selection Recommendations

The B32529C1473K000 from EPCOS - TDK Electronics is a qualified substitute for the obsolete PVC114 based on the following engineering criteria:

Electrical Performance: Both components maintain 100V DC voltage rating and ±10% tolerance specification. The capacitance variance (0.04 µF to 0.047 µF) falls within the ±10% tolerance band, ensuring functional equivalence in general-purpose applications.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component procurement and deployment.

Manufacturing Status: The B32529C1473K000 is classified as active product, ensuring long-term availability and supply chain continuity compared to the obsolete PVC114.

Physical Integration: Both components feature through-hole radial configuration with PC pin termination. Physical dimensions differ (PVC114: 0.350" Dia x 0.701" L; B32529C1473K000: 0.287" L x 0.098" W), requiring PCB layout verification prior to implementation.

Temperature Performance: Identical operating temperature range (-55°C to 125°C) ensures thermal compatibility across specified application environments.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1473K000 directly replace the PVC114 without circuit modification?

A: Electrical substitution is valid based on capacitance tolerance, voltage rating, and operating temperature equivalence. Physical PCB layout must be verified due to dimensional differences. Lead spacing differs (PVC114: 0.500"; B32529C1473K000: 0.197"), requiring footprint assessment.

Q: What is the significance of the capacitance difference between 0.04 µF and 0.047 µF?

A: Both values fall within the ±10% tolerance specification. In general-purpose applications, this variance is functionally equivalent. Circuit-specific tolerance requirements must be evaluated for precision applications.

Q: Are there any AC voltage considerations when substituting these parts?

A: The PVC114 is rated 70V AC while the B32529C1473K000 is rated 63V AC. For DC-only applications, this difference is not relevant. AC applications must confirm that operating voltage does not exceed 63V AC.

Q: What is the impact of different dielectric material specifications?

A: Both components use polyester-based dielectric materials. The B32529C1473K000 specifies metallized-stacked construction, which is a modern manufacturing variant of polyester film capacitors. Electrical performance remains equivalent for general-purpose applications.

Q: How should PCB layout be modified for the B32529C1473K000?

A: The substitute part has significantly smaller physical dimensions and different lead spacing (5.00mm vs 12.70mm). PCB footprint must be redesigned to accommodate the new component geometry. Height-seated maximum is 6.50mm compared to the original design.

Q: Is the B32529C1473K000 suitable for automotive applications?

A: The B32529C1473K000 is rated for automotive applications with AEC-Q200 compliance. The original PVC114 is specified for general-purpose use. Automotive-specific requirements must be confirmed if the application demands automotive-grade components.
