PVC1021 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC1021 is a 1000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring polyester dielectric construction. This component features a 1 kV DC voltage rating with ±10% capacitance tolerance and radial through-hole mounting configuration.

The PVC1021 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC1021 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 1000 pF
• Capacitance tolerance: ±10%
• Voltage rating - DC: 1000V (1kV) minimum
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Dielectric material: Alternative film dielectrics (polyester, polypropylene) are acceptable provided electrical performance remains within specification
• Voltage rating - AC: May exceed the original 200V specification
• Operating temperature range: May differ if minimum and maximum bounds support the application environment
• Physical dimensions: May vary within radial package constraints
• Lead spacing: May differ if PCB layout accommodates the variation

The DPPM10D1K-F qualifies as a substitute based on matching capacitance, tolerance, DC voltage rating, mounting type, package configuration, and termination style. Dielectric material differs (polypropylene versus polyester), and AC voltage rating is elevated (450V versus 200V), representing acceptable parameter variations for this component category.

Parameter Comparison

Engineering Selection Recommendations

PVC1021 (Obsolete Status): The PVC1021 is classified as obsolete. Continued sourcing is limited to existing inventory. Current stock availability is 726 pieces. For new designs or long-term production requirements, transition to an active substitute is recommended to ensure supply chain continuity.

DPPM10D1K-F (Active Status): The DPPM10D1K-F is an active product with significantly higher inventory availability (2501 pieces). This substitute maintains electrical equivalence across all critical parameters: capacitance, tolerance, and DC voltage rating. The component is manufactured by the same supplier (CDE), ensuring consistent quality and reliability standards.

Compliance Considerations: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Physical Integration: The DPPM10D1K-F exhibits different physical dimensions and lead spacing compared to the PVC1021. PCB layout verification is required to confirm mechanical compatibility. The substitute features a longer body (25.00mm versus 8.40mm) and increased lead spacing (0.827" versus 0.500"), which may necessitate PCB redesign or component repositioning.

Frequently Asked Questions (FAQ)

Q: Can the DPPM10D1K-F directly replace the PVC1021 without circuit modification?

A: Electrical substitution is valid. The DPPM10D1K-F maintains identical capacitance (1000 pF), tolerance (±10%), and DC voltage rating (1000V). However, physical dimensions and lead spacing differ significantly. PCB layout compatibility must be verified before implementation. No circuit electrical modifications are required if physical placement is accommodated.

Q: Why does the DPPM10D1K-F have a higher AC voltage rating (450V versus 200V)?

A: The AC voltage rating difference reflects the dielectric material composition. The DPPM10D1K-F uses polypropylene (PP) metallized film, which exhibits different electrical characteristics compared to the polyester dielectric in the PVC1021. The elevated AC rating does not affect DC circuit operation and represents an acceptable parameter variation for substitution purposes.

Q: What is the impact of the different operating temperature ranges?

A: The PVC1021 operates from -55°C to 125°C, while the DPPM10D1K-F operates from -40°C to 105°C. If the application requires operation below -40°C or above 105°C, the DPPM10D1K-F is not suitable. For applications within the -40°C to 105°C range, both components are compatible.

Q: Are there any compliance or certification differences between these components?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance or certification barriers exist for substitution.

Q: What is the lead spacing difference, and does it affect PCB design?

A: The PVC1021 has 0.500" (12.70mm) lead spacing, while the DPPM10D1K-F has 0.827" (21.00mm) lead spacing. This difference requires PCB footprint modification. The substitute cannot be installed in a PCB designed for the original component without layout revision.

Q: Is the DPPM10D1K-F available in the same packaging as the PVC1021?

A: Both components use radial through-hole packaging with PC pin termination. However, the physical dimensions differ. The PVC1021 is 0.331" diameter by 0.701" length, while the DPPM10D1K-F is 0.984" length by 0.256" width with 0.512" seated height. Packaging category differs (PVC1021 is tape/reel; DPPM10D1K-F is bulk).
