DME4P15K Equivalent & Substitute Parts

Part Overview

The DME4P15K is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400V DC voltage rating and polyester metallized dielectric construction. This component is classified as obsolete, indicating that direct procurement from original manufacturing sources may be limited or unavailable. Identifying equivalent and substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this capacitor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME4P15K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.15 µF
• Tolerance: ±10%
• Voltage rating: 400V DC / 200V AC minimum
• Dielectric type: Polyester, Metallized

Mechanical Parameters:

• Mounting configuration: Through Hole, Radial
• Lead spacing: 0.591" (15.00mm)
• Termination style: PC Pins
• Physical dimensions compatible with original footprint

Environmental Parameters:

• Operating temperature range: -55°C ~ 125°C

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Parts meeting these criteria are classified as direct equivalents and may be used interchangeably in the original application.

Engineering Selection Recommendations

DME4P15K-F (Primary Substitute)

The DME4P15K-F is the direct equivalent manufactured by Cornell Dubilier Electronics and maintains identical electrical and mechanical specifications to the original DME4P15K. The primary distinction is product status: the DME4P15K-F is classified as active, ensuring ongoing availability and supply chain continuity. Additionally, the DME4P15K-F carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications requiring RoHS compliance, the DME4P15K-F is the appropriate selection.

B32522C6154J (Alternative Substitute)

The B32522C6154J, manufactured by KEMET, provides electrical and mechanical equivalence to the DME4P15K across all specified parameters. This part is active in production and carries ROHS3 compliance certification. Selection of this alternative is appropriate when CDE sourcing is constrained or when multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can the DME4P15K-F be used as a direct replacement for the DME4P15K?

A: Yes. The DME4P15K-F is electrically and mechanically equivalent to the DME4P15K. Both parts share identical capacitance, voltage rating, dielectric material, operating temperature range, and physical dimensions. The primary difference is product status and RoHS compliance.

Q: What is the significance of the obsolete status of the DME4P15K?

A: Obsolete status indicates that the original manufacturer has discontinued production. This creates supply constraints and limits long-term availability. The DME4P15K-F, as an active product, provides a path to sustained component sourcing.

Q: Are there mechanical compatibility concerns when substituting the DME4P15K?

A: No. All substitute parts listed maintain identical lead spacing (0.591" / 15.00mm), termination style (PC Pins), and radial package configuration. PCB footprints designed for the DME4P15K accommodate all listed substitutes without modification.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and manufacturing processes, not electrical characteristics. Both RoHS-compliant and non-compliant versions of this capacitor deliver identical electrical performance within the specified parameters.

Q: Can the B32522C6154J be used in applications originally designed for the DME4P15K?

A: Yes. The B32522C6154J meets all electrical and mechanical requirements specified for the DME4P15K. Cross-manufacturer substitution is valid when all critical parameters align.

Q: What parameters must remain constant for a valid substitution?

A: Capacitance value, tolerance, voltage rating (DC and AC), dielectric material, operating temperature range, lead spacing, and package configuration must all match the original specification. Deviation in any of these parameters invalidates the substitution.
