PVC10218 Equivalent & Substitute Parts

Part Overview

The PVC10218 is a 1800 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 1000V DC voltage rating and ±10% tolerance. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. The radial through-hole configuration and polyester dielectric construction define its primary application profile.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC10218 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 1800 pF
• Tolerance: ±10%
• Voltage Rating - DC: 1000V (1kV) minimum
• Mounting Type: Through Hole
• Package / Case: Radial
• Termination: PC Pins
• RoHS3 Compliance

Allowable Variations:

• Dielectric material may differ (polyester to polypropylene metallized)
• AC voltage rating may exceed the original specification
• Operating temperature range may be narrower or broader
• Physical dimensions may vary within radial package constraints
• Lead spacing may differ based on package geometry

The DPPM10D18K-F qualifies as a substitute based on matching all mandatory criteria while maintaining electrical performance at the specified 1000V DC rating.

Parameter Comparison

Engineering Selection Recommendations

The DPPM10D18K-F serves as a direct functional substitute for the obsolete PVC10218 based on the following engineering considerations:

Electrical Equivalence: Both components maintain identical capacitance (1800 pF), tolerance (±10%), and critical DC voltage rating (1000V). The DPPM10D18K-F provides enhanced AC voltage capability (450V versus 200V), which presents no compatibility constraint in applications designed for the original part.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing and procurement standards. The substitute part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete PVC10218.

Physical Integration: The DPPM10D18K-F exhibits larger physical dimensions and increased lead spacing (0.827" versus 0.500"). PCB layout verification is required to confirm mechanical fit within existing designs. The radial through-hole configuration and PC pin termination remain consistent with the original specification.

Dielectric Consideration: The substitution introduces polypropylene metallized dielectric in place of polyester. This material change alters frequency response and temperature stability characteristics. The DPPM10D18K-F operates within a narrower temperature range (-40°C ~ 105°C versus -55°C ~ 125°C), which must be evaluated against application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the DPPM10D18K-F directly replace the PVC10218 without circuit modification?

A: Electrical substitution is valid based on matching capacitance, tolerance, and 1000V DC rating. Physical substitution requires PCB layout verification due to increased component dimensions and lead spacing (0.827" versus 0.500").

Q: What is the significance of the dielectric material change from polyester to polypropylene metallized?

A: Dielectric material affects frequency response, temperature coefficient, and ESR characteristics. Polypropylene metallized construction typically provides lower ESR and improved high-frequency performance. Application-specific frequency requirements must be evaluated.

Q: Does the narrower operating temperature range of the DPPM10D18K-F (-40°C ~ 105°C) present a limitation?

A: The substitute part operates within a narrower range than the original (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C cannot use this substitute without thermal analysis confirmation.

Q: Why does the DPPM10D18K-F have higher AC voltage rating (450V versus 200V)?

A: The higher AC rating reflects the polypropylene metallized dielectric construction, which exhibits superior AC performance. This parameter does not constrain substitution in applications designed for the original 200V AC specification.

Q: Is PCB layout modification necessary for the DPPM10D18K-F substitution?

A: Yes. The lead spacing increases from 0.500" (12.70mm) to 0.827" (21.00mm), and physical dimensions change significantly. PCB footprint verification is mandatory before component placement.

Q: Are both parts compliant with current regulatory standards?

A: Both the PVC10218 and DPPM10D18K-F maintain ROHS3 compliance and REACH unaffected status. The substitute part's active product status ensures compliance with evolving regulatory requirements.
