DME4P15K-F Equivalent & Substitute Parts

Part Overview

The DME4P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) designed for general-purpose applications. This radial through-hole component operates across a temperature range of -55°C to 125°C with a 400V DC voltage rating and ±10% capacitance tolerance. The part is currently in active production status with 873 units available in inventory.

Substitute parts become necessary when the original component reaches end-of-life status, inventory depletion occurs, or when design requirements permit tolerance or performance parameter variations. The B32522C6154J represents an available alternative that maintains critical electrical specifications while offering improved tolerance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME4P15K-F with the B32522C6154J is permissible based on the following alignment of critical parameters:

Electrical Equivalence:

• Capacitance value: Both parts rated at 0.15 µF
• Voltage rating: Both rated 400V DC / 200V AC
• Dielectric material: Both utilize polyester, metallized construction
• Operating temperature: Both support -55°C to 125°C range
• Termination: Both feature PC pins for through-hole mounting

Mechanical Compatibility:

• Lead spacing: Both maintain 0.591" (15.00mm) pitch for standard PCB hole patterns
• Mounting type: Both are radial through-hole components

Tolerance Consideration: The substitute part B32522C6154J offers ±5% tolerance compared to the original ±10% tolerance. Tighter tolerance is acceptable in substitution scenarios and does not create incompatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: The DME4P15K-F remains the primary selection. This component maintains active product status, ensuring long-term availability and supply chain stability. Current inventory of 873 units supports immediate procurement requirements.

For Replacement and Retrofit Applications: The B32522C6154J serves as a direct electrical and mechanical substitute when the DME4P15K-F becomes unavailable. The substitute part satisfies all critical electrical parameters: identical capacitance, voltage rating, temperature range, and lead spacing. The ±5% tolerance of the substitute part provides improved precision compared to the original ±10% specification, which is advantageous in applications where tighter capacitance control is beneficial.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between these parts does not introduce regulatory compliance risk.

Physical Integration: The B32522C6154J exhibits a lower seated height (0.433" versus 0.488") and slightly different length and width dimensions. These variations remain within acceptable tolerances for standard through-hole PCB layouts with 15.00mm lead spacing. Physical clearance verification is recommended for applications with space constraints.

Product Status Impact: The B32522C6154J carries "Not For New Designs" status, indicating EPCOS has discontinued active development for this component. This designation does not affect its suitability for replacement applications but suggests the DME4P15K-F should remain the preferred choice for new product development.

Frequently Asked Questions (FAQ)

Q: Can the B32522C6154J directly replace the DME4P15K-F in existing circuits?

A: Yes. Both components share identical capacitance (0.15 µF), voltage ratings (400V DC / 200V AC), operating temperature range (-55°C to 125°C), and lead spacing (15.00mm). The substitute part's ±5% tolerance is tighter than the original ±10%, which does not create incompatibility. Physical dimensions vary slightly, but both maintain standard radial through-hole form factors compatible with conventional PCB layouts.

Q: What is the significance of the "Not For New Designs" status on the B32522C6154J?

A: This designation indicates that EPCOS has discontinued active development and marketing of this component for new product applications. However, the part remains electrically and mechanically equivalent to the DME4P15K-F and is suitable for replacement, retrofit, and legacy system applications. For new product development, the DME4P15K-F is the recommended selection.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist. The B32522C6154J is slightly shorter (0.433" seated height versus 0.488") and has marginally different length and width measurements. These differences do not affect lead spacing (both 15.00mm) and remain compatible with standard through-hole PCB designs. Applications with severe height constraints should verify clearance before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DME4P15K-F and B32522C6154J are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards for electronic components.

Q: Which part should be selected for new product development?

A: The DME4P15K-F is the recommended selection for new designs. This component maintains active product status with established supply chain support and 873 units currently in inventory. The B32522C6154J should be reserved for replacement and retrofit applications where the original part is unavailable.

Q: How does the tolerance difference affect circuit performance?

A: The B32522C6154J offers ±5% tolerance compared to the DME4P15K-F's ±10% tolerance. Tighter tolerance provides improved capacitance precision and is generally advantageous in applications sensitive to capacitance variation. This difference does not create incompatibility and may enhance circuit performance in precision-critical applications.
