Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM4S15K-F is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.015 µF (exact match required)
• Voltage rating: 400V DC minimum
• Tolerance: ±10% or tighter
• Mounting configuration: Through-hole radial
• Regulatory compliance: ROHS3 Compliant

Allowable Variations:

• Dielectric material: Alternative film types (polyester, polypropylene) permitted if electrical specifications are maintained
• Physical dimensions: Variations acceptable within PCB layout constraints
• Lead spacing: Minor variations acceptable if through-hole mounting is preserved
• Operating temperature range: Substitute may have narrower range if minimum requirements are met
• AC voltage rating: May differ from original specification

The identified substitute part 225P15394XD3 meets all mandatory matching parameters while utilizing a polyester dielectric instead of polypropylene, resulting in different physical dimensions and thermal characteristics.

Engineering Selection Recommendations

DPM4S15K-F Selection Criteria:

• Primary choice for applications requiring polypropylene dielectric characteristics and low ESR/ESL performance
• Suitable for high-frequency switching applications with thermal requirements up to 105°C
• Compact form factor (13.00mm x 7.00mm) for space-constrained PCB layouts
• 220V AC rating supports broader AC voltage applications
• ROHS3 compliant for regulated manufacturing environments

225P15394XD3 Selection Criteria:

• Alternative selection when DPM4S15K-F availability is limited
• Polyester dielectric suitable for audio and DC filtering applications
• Larger physical footprint (20.30mm x 7.10mm) requires PCB layout verification
• Operating temperature maximum of 85°C limits use in high-temperature environments
• 200V AC rating is lower than main part; verify AC voltage requirements
• Closer lead spacing (9.50mm vs 10.00mm) requires PCB hole pattern confirmation
• ROHS3 compliant for regulated manufacturing environments

Both parts maintain identical DC voltage rating (400V), capacitance (0.015 µF), and tolerance (±10%), ensuring electrical equivalence for DC link and DC filtering functions. Physical dimension differences necessitate PCB layout review before substitution.

Frequently Asked Questions (FAQ)

Q: Can 225P15394XD3 be used as a direct replacement for DPM4S15K-F?

A: Electrical substitution is valid for DC link and DC filtering applications. However, physical dimensions differ: the substitute is larger (20.30mm vs 13.00mm length) and has closer lead spacing (9.50mm vs 10.00mm). PCB layout compatibility must be confirmed before installation.

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

A: The DPM4S15K-F uses polypropylene with metallized construction, providing lower ESR and ESL characteristics suitable for high-frequency switching. The 225P15394XD3 uses polyester, which has different frequency response and temperature stability characteristics. Both maintain the same 400V DC rating and 0.015 µF capacitance.

Q: Does the substitute part have the same temperature rating?

A: No. The DPM4S15K-F operates from -55°C to 105°C, while the 225P15394XD3 operates from -55°C to 85°C. Applications requiring operation above 85°C must use the DPM4S15K-F.

Q: Are both parts RoHS compliant?

A: Yes. Both DPM4S15K-F and 225P15394XD3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of the different AC voltage ratings?

A: The DPM4S15K-F has a 220V AC rating while the 225P15394XD3 has a 200V AC rating. For applications involving AC voltage stress, the lower rating of the substitute must be verified against circuit requirements. Both maintain identical 400V DC ratings.

Q: Can I use these capacitors interchangeably in audio applications?

A: The 225P15394XD3 is specified for audio applications. The DPM4S15K-F is specified for DC link and high-frequency switching. While both can function in audio circuits, the polyester dielectric of the substitute may be more suitable for audio frequency response characteristics.

Q: What should I verify before substituting these parts?

A: Confirm PCB hole spacing compatibility (10.00mm vs 9.50mm lead spacing), verify available vertical clearance (14.00mm vs 14.70mm height), confirm operating temperature requirements do not exceed 85°C for the substitute, and validate AC voltage stress levels if present in the application.
