DME10P1K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME10P1K is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) rated for 1000V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued procurement and system maintenance. The part features radial through-hole mounting suitable for general-purpose applications requiring high voltage film capacitor performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DME10P1K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.1 µF (exact match required)
• Voltage Rating - DC: 1000V minimum (no reduction permitted)
• Voltage Rating - AC: 250V minimum (no reduction permitted)
• Dielectric Type: Polyester, Metallized (material class must match)
• Tolerance: ±10% (electrical tolerance specification)
• Operating Temperature Range: -55°C to 125°C (thermal operating envelope)
• Mounting Configuration: Through Hole, Radial (mechanical compatibility)
• Lead Spacing: 0.689" (17.50mm) (PCB layout compatibility)
• Termination Style: PC Pins (connection method)

Only parts meeting all these criteria are classified as direct substitutes. Variations in packaging format, product status, or compliance certifications do not affect functional substitutability when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The DME10P1K-F serves as the direct functional equivalent to the obsolete DME10P1K. Both parts are manufactured by Cornell Dubilier Electronics within the DME series and maintain identical electrical specifications across capacitance, voltage ratings, dielectric composition, and operating temperature range. Mechanical compatibility is confirmed through matching lead spacing (0.689" / 17.50mm) and radial through-hole mounting configuration.

The seated height difference of 0.059" (1.50mm) between the main part (0.787" maximum) and substitute (0.846" maximum) represents a minor dimensional variation within typical component tolerance ranges and does not affect functional performance or standard PCB layout compatibility.

The DME10P1K-F is classified as active product status, ensuring continued availability and supply chain reliability. The substitute part achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic component procurement in regulated industries.

Selection of the DME10P1K-F is appropriate for all applications previously served by the DME10P1K where product availability and regulatory compliance are considerations.

Frequently Asked Questions (FAQ)

Q: Can the DME10P1K-F replace the DME10P1K in existing designs?

A: Yes. The DME10P1K-F maintains identical electrical parameters (0.1 µF capacitance, 1000V DC rating, ±10% tolerance, polyester metallized dielectric) and mechanical specifications (radial through-hole, 0.689" lead spacing, PC pin termination). The 1.50mm seated height difference does not affect standard PCB layout compatibility.

Q: What is the primary reason for substitution?

A: The DME10P1K is classified as obsolete product status. The DME10P1K-F is the active equivalent part from the same manufacturer and series, ensuring continued procurement availability.

Q: Are there compliance differences between these parts?

A: The DME10P1K-F achieves ROHS3 compliance, while the original DME10P1K is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Q: Does the seated height variation affect circuit performance?

A: No. The 0.059" (1.50mm) maximum seated height difference is a mechanical dimension variation that does not impact electrical performance or standard through-hole PCB assembly processes.

Q: Are both parts from the same manufacturer?

A: Yes. Both the DME10P1K and DME10P1K-F are manufactured by Cornell Dubilier Electronics (CDE) and belong to the DME series.

Q: What packaging formats are available?

A: The original DME10P1K is available in standard packaging. The DME10P1K-F is supplied in bulk packaging format.
