DME6P27K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME6P27K is a 0.27 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 630V DC voltage rating and ±10% tolerance. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and system maintenance. The part features polyester metallized dielectric construction in a radial through-hole package suitable for general-purpose applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME6P27K is determined by strict equivalence across electrical and mechanical parameters. The substitute part must maintain identical capacitance value (0.27 µF), tolerance (±10%), voltage ratings (630V DC / 250V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), mounting configuration (through-hole radial), and lead spacing (0.886" / 22.50mm).

The DME6P27K-F qualifies as a direct substitute based on complete parameter alignment across all critical electrical specifications and mechanical dimensions. The primary distinction between these parts is product status and compliance certification, not functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DME6P27K-F is the direct equivalent for the obsolete DME6P27K. Both parts are manufactured by Cornell Dubilier Electronics within the DME series and share identical electrical specifications and core mechanical dimensions.

Product Status Consideration: The DME6P27K is classified as obsolete, while the DME6P27K-F maintains active production status. For new designs and ongoing procurement, the DME6P27K-F is the appropriate selection.

Compliance Consideration: The DME6P27K-F carries RoHS3 compliance certification, whereas the original DME6P27K is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. Both parts maintain REACH Unaffected status and carry EAR99 ECCN classification.

Physical Dimension Note: The seated height differs marginally between parts (0.650" versus 0.709"). This 0.059" (1.50mm) variation requires verification against PCB layout constraints and clearance specifications in the target application.

Frequently Asked Questions (FAQ)

Q: Can DME6P27K-F replace DME6P27K in existing designs?

A: Yes. The DME6P27K-F is electrically and mechanically equivalent across all critical parameters: capacitance, tolerance, voltage ratings, dielectric material, operating temperature range, mounting type, and lead spacing. The seated height difference of 0.059" (1.50mm) must be evaluated against available PCB clearance.

Q: What is the primary reason to transition from DME6P27K to DME6P27K-F?

A: The DME6P27K is obsolete and no longer in production. The DME6P27K-F is the active equivalent from the same manufacturer and series, ensuring continued component availability and supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The DME6P27K-F is RoHS3 compliant, while the DME6P27K is RoHS non-compliant. For applications requiring RoHS compliance, the DME6P27K-F is the required selection. Both parts are REACH Unaffected.

Q: Does the height difference affect PCB compatibility?

A: The DME6P27K-F has a maximum seated height of 0.709" compared to 0.650" for the original part. This 0.059" (1.50mm) increase must be confirmed against PCB layout clearance specifications, component spacing, and enclosure constraints.

Q: Are both parts from the same manufacturer?

A: Yes. Both the DME6P27K and DME6P27K-F are manufactured by Cornell Dubilier Electronics and belong to the DME series.

Q: What packaging options are available?

A: The DME6P27K is available in standard packaging, while the DME6P27K-F is supplied in bulk packaging. Both maintain identical electrical and mechanical specifications.
