PVC6139 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC6139 is a 0.039 µF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600V DC operation with ±10% tolerance. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The radial through-hole configuration and general-purpose application profile support direct substitution with compatible alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Parameter	Value	Substitution Relevance
Capacitance	0.039 µF	Critical - must match exactly
Tolerance	±10%	Critical - determines circuit accuracy
Voltage Rating (DC)	600V	Critical - minimum requirement for substitution
Voltage Rating (AC)	200V	Important - application-dependent
Dielectric Material	Polyester	Important - affects performance characteristics
Mounting Type	Through Hole Radial	Critical - determines PCB compatibility
Operating Temperature Range	-55°C to 125°C	Important - environmental suitability
Lead Spacing	0.969" (24.60mm)	Critical - PCB hole pattern compatibility
RoHS Status	ROHS3 Compliant	Important - regulatory compliance

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6139 is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Criteria:

Capacitance value must equal 0.039 µF
Tolerance must be ±10% or tighter
DC voltage rating must be equal to or greater than 600V
AC voltage rating should support the application requirement of 200V or higher
Dielectric material must be polyester-based

Mechanical Criteria:

Mounting configuration must be through-hole radial
Lead spacing must accommodate 0.969" (24.60mm) PCB hole patterns
Package dimensions must fit within the original footprint constraints

Compliance Criteria:

RoHS3 compliance required for new designs
REACH compliance status must be unaffected or compliant

The ECQ-E6393KF from Panasonic Electronic Components meets all substitution criteria with enhanced specifications in voltage rating (630V DC) and AC rating (250V), while maintaining identical capacitance and tolerance values.

RoHS Status	ROHS3 Compliant	ROHS3 Compliant	Identical
Product Status	Obsolete	Active	Substitute is current production

Engineering Selection Recommendations

Direct PCB Substitution: The ECQ-E6393KF cannot be used as a direct pin-compatible replacement due to significantly different lead spacing (0.394" versus 0.969"). The substitute part requires PCB redesign or mechanical adaptation to accommodate the reduced lead pitch.

Electrical Suitability: The ECQ-E6393KF exceeds the electrical requirements of the PVC6139 in both DC (630V vs. 600V) and AC (250V vs. 200V) voltage ratings, making it electrically suitable for applications requiring the original specifications.

Temperature Consideration: The PVC6139 operates across -55°C to 125°C, while the ECQ-E6393KF is rated -40°C to 105°C. Applications requiring operation below -40°C or above 105°C cannot use the Panasonic substitute without thermal performance verification.

Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing standards.

Product Availability: The PVC6139 is obsolete with limited inventory (1120 pcs). The ECQ-E6393KF is active production with current availability (1406 pcs), providing supply chain continuity for new designs.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6393KF be soldered directly into a PVC6139 footprint?

A: No. The lead spacing differs significantly (0.394" vs. 0.969"), making direct PCB substitution impossible without footprint modification. PCB redesign or mechanical adapter solutions are required.

Q: Are the electrical specifications of the ECQ-E6393KF sufficient for PVC6139 applications?

A: Yes. The substitute part exceeds the original specifications with higher voltage ratings (630V DC and 250V AC) and identical capacitance and tolerance values, supporting all electrical requirements of the original design.

Q: What is the impact of the metallized polyester dielectric in the ECQ-E6393KF?

A: Metallized polyester film provides self-healing properties and improved performance characteristics compared to standard polyester. This represents an enhancement over the original PVC6139 specification.

Q: Does the narrower operating temperature range of the ECQ-E6393KF affect substitution suitability?

A: Temperature range compatibility depends on application requirements. If the system operates within -40°C to 105°C, the substitute is suitable. Applications requiring -55°C operation require alternative solutions.

Q: Are both components RoHS compliant?

A: Yes. Both the PVC6139 and ECQ-E6393KF are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: What is the lead time and availability status for each part?

A: The PVC6139 is obsolete with limited stock (1120 pcs). The ECQ-E6393KF is active production with current availability (1406 pcs), providing better long-term supply assurance.
