DME2P27K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME2P27K is a 0.27 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating and ±10% tolerance. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing system maintenance and new production applications. The radial through-hole configuration and polyester metallized dielectric make this capacitor suitable for general-purpose filtering and coupling applications in electronic circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME2P27K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.27 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (minimum requirement; higher ratings are acceptable)
• Voltage Rating - AC: 160V (minimum requirement; higher ratings are acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required for PCB compatibility)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility with existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The DME2P27K-F serves as the direct substitute for the obsolete DME2P27K. Both components are manufactured by Cornell Dubilier Electronics within the same DME series and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The DME2P27K-F is classified as active and carries ROHS3 compliance certification, whereas the original DME2P27K is obsolete and RoHS non-compliant. For new designs and ongoing production requiring compliance with current environmental regulations, the DME2P27K-F is the appropriate selection.

Both parts maintain identical performance characteristics: 0.27 µF capacitance, ±10% tolerance, 250V DC / 160V AC voltage ratings, polyester metallized dielectric, and -55°C to 125°C operating temperature range. Physical dimensions, lead spacing, and mounting configuration are identical, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the DME2P27K-F be used as a direct replacement for the DME2P27K?

A: Yes. The DME2P27K-F is electrically and mechanically equivalent to the DME2P27K. All critical parameters—capacitance, voltage rating, tolerance, dielectric material, operating temperature range, physical dimensions, and lead spacing—are identical. Direct substitution is possible without circuit or PCB modifications.

Q: What is the difference between the DME2P27K and DME2P27K-F?

A: The primary differences are product status and regulatory compliance. The DME2P27K is obsolete and RoHS non-compliant. The DME2P27K-F is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the DME2P27K-F for the DME2P27K?

A: No compatibility concerns exist. Both components feature identical lead spacing (0.394" / 10.00mm), radial through-hole mounting, PC pin termination, and physical dimensions (0.492" L x 0.236" W). PCB layouts designed for the DME2P27K will accommodate the DME2P27K-F without modification.

Q: Does the DME2P27K-F meet current environmental regulations?

A: Yes. The DME2P27K-F carries ROHS3 compliance certification and is REACH unaffected. The original DME2P27K is RoHS non-compliant. For applications requiring regulatory compliance, the DME2P27K-F is the appropriate selection.

Q: What is the operating temperature range for both parts?

A: Both the DME2P27K and DME2P27K-F operate across the temperature range of -55°C to 125°C, ensuring performance stability across industrial and commercial applications.

Q: Are the voltage ratings identical between the two parts?

A: Yes. Both components are rated for 250V DC and 160V AC, providing equivalent electrical performance in circuit applications.
