DPM2S15K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2S15K-F is a 0.015 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for DC filtering and high-frequency switching applications. This radial through-hole component features a polypropylene metallized dielectric with a 250V DC voltage rating and ±10% capacitance tolerance. The part is currently in active production status with 787 units in stock. Substitute parts are identified when equivalent capacitance and tolerance specifications are required but alternative voltage ratings, dielectric materials, or physical dimensions are acceptable for the application circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DPM2S15K-F is based on the following criteria:

Mandatory Match Parameters:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±10% (substitute tolerance must be equal or tighter)
• Mounting type: Through-hole radial configuration
• Termination: PC pins for PCB insertion

Allowable Variation Parameters:

• Voltage rating: Substitute must equal or exceed 250V DC
• Dielectric material: Alternative dielectric types acceptable if electrical performance is maintained
• Physical dimensions: Variations permitted within PCB layout constraints
• Operating temperature: Substitute range must cover minimum -55°C to 105°C or application-specific subset

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required

The substitute part 225P15394XD3 meets all mandatory parameters with a higher voltage rating (400V DC) and alternative polyester dielectric, making it suitable for applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (DPM2S15K-F): Use the DPM2S15K-F when polypropylene dielectric characteristics are required for the application. This part offers low ESR and low ESL performance suitable for high-frequency switching and DC link filtering. The 250V DC rating is appropriate for standard industrial and consumer electronics applications. Active production status and 787 units in stock ensure availability.

Substitute Part Selection (225P15394XD3): The 225P15394XD3 (Orange Drop® 225P series) serves as a substitute when the DPM2S15K-F is unavailable. This part provides identical capacitance and tolerance with a higher 400V DC voltage rating, offering additional safety margin in voltage-stressed circuits. The polyester dielectric provides alternative ESR/ESL characteristics compared to polypropylene. Active production status and 1086 units in stock provide superior availability.

Selection Constraints:

• Lead spacing differs by 0.020" (0.50mm); verify PCB hole pattern compatibility before substitution
• Operating temperature upper limit of 85°C for the substitute part is lower than the main part's 105°C; confirm application temperature requirements
• Dielectric material change from polypropylene to polyester affects frequency response and ESR characteristics; evaluate circuit performance requirements

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), suitable for standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 225P15394XD3 be used as a direct replacement for the DPM2S15K-F?

A: The 225P15394XD3 is functionally compatible for capacitance and tolerance requirements. However, verify two factors before substitution: (1) PCB hole pattern compatibility due to 0.020" lead spacing difference, and (2) application operating temperature, as the substitute part is rated to 85°C maximum versus 105°C for the original part.

Q: What is the difference between polypropylene and polyester dielectrics in these capacitors?

A: Polypropylene (DPM2S15K-F) offers lower ESR and ESL, making it preferred for high-frequency switching applications. Polyester (225P15394XD3) provides higher voltage density and different frequency response characteristics. Selection depends on circuit-specific performance requirements.

Q: Are both parts RoHS compliant?

A: Yes, both DPM2S15K-F and 225P15394XD3 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: The 400V DC rating of the 225P15394XD3 versus 250V DC of the DPM2S15K-F provides additional voltage margin but does not negatively affect performance in circuits designed for 250V operation. The capacitance value and tolerance remain identical.

Q: What is the lead spacing difference and why does it matter?

A: The DPM2S15K-F has 0.394" (10.00mm) lead spacing while the 225P15394XD3 has 0.374" (9.50mm) spacing. This 0.020" difference requires verification against PCB hole pattern specifications to ensure proper component insertion and solder joint formation.

Q: Can I use the substitute part in high-temperature applications?

A: The 225P15394XD3 is rated to 85°C maximum, which is 20°C lower than the DPM2S15K-F's 105°C rating. For applications requiring sustained operation above 85°C, the original DPM2S15K-F is required.

Q: Are both parts available in the same packaging format?

A: Both parts use through-hole radial packaging with PC pins. The DPM2S15K-F is specified as "-" packaging while the 225P15394XD3 is supplied in bulk packaging. Both are suitable for standard PCB assembly processes.
