DPP4S15K-F

Part Overview

The DPP4S15K-F is a 0.015 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) from the DPP series. This radial polypropylene (PP) metallized capacitor is rated for 400V DC operation and is currently in active production status. Film capacitors of this specification are essential in high-frequency and switching applications where low ESR performance and reliable dielectric stability are required. Identifying equivalent substitute parts ensures design flexibility and supply chain continuity when the primary part becomes unavailable or when alternative electrical characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for film capacitors is determined by the following criteria, all of which must be satisfied:

1. Matching Capacitance Value: The substitute must have identical capacitance of 0.015 µF to maintain circuit performance and signal integrity.

2. Voltage Rating Compatibility: The substitute's DC voltage rating must equal or exceed 400V. Higher voltage ratings provide design margin but do not compromise electrical performance.

3. Dielectric Material: Both the main part and substitute use polypropylene (PP) metallized dielectric, ensuring equivalent frequency response, ESR characteristics, and environmental stability.

4. Temperature Range: Operating temperature range of -55°C ~ 105°C is consistent across parts, meeting reliability requirements across industrial temperature extremes.

5. Mounting and Mechanical Compatibility: Through-hole radial mounting with 0.394" (10.00mm) lead spacing ensures physical interchangeability on PCB layouts designed for the DPP4S15K-F.

6. Compliance Standards: RoHS3 compliance and REACH unaffected status are mandatory for equivalent substitution in regulated applications.

The PHE426MA5150JR05 from KEMET satisfies all substitution criteria, with enhanced voltage rating (630V DC) providing additional design margin.

Parameter Comparison

Engineering Selection Recommendations

Both the DPP4S15K-F and PHE426MA5150JR05 are active production components with full RoHS3 compliance and REACH unaffected status, making them suitable for modern manufacturing environments and regulated applications.

The PHE426MA5150JR05 offers tighter capacitance tolerance (±5% versus ±10%) and elevated DC voltage rating (630V versus 400V). The reduced physical envelope (13.00mm × 4.00mm versus 15.00mm × 9.00mm) may present design constraints or advantages depending on PCB layout requirements.

Selection between these parts should be based on:

• Tolerance requirements: Choose PHE426MA5150JR05 if ±5% tolerance is specified.
• Voltage margin: Choose PHE426MA5150JR05 if enhanced voltage headroom is required.
• Physical constraints: Verify PCB layout compatibility with differing component dimensions.
• Supply availability: Both parts maintain active inventory status.

Frequently Asked Questions (FAQ)

Q: Can the PHE426MA5150JR05 directly replace the DPP4S15K-F?

A: Yes, the PHE426MA5150JR05 is electrically and mechanically compatible. Both parts share identical capacitance (0.015 µF), polypropylene dielectric, temperature range (-55°C ~ 105°C), and lead spacing (10.00mm). The KEMET part provides higher voltage rating and tighter tolerance, representing equivalent or superior performance. Verify PCB layout compatibility given dimensional differences.

Q: Why does the KEMET part have a higher voltage rating?

A: Higher voltage ratings reflect different internal dielectric layer thicknesses designed for greater electrical stress capability. This provides additional design margin and is common across manufacturer product lines for the same capacitance value. The higher rating does not degrade performance at the 400V operating point.

Q: Are there tolerance differences between these parts?

A: The DPP4S15K-F carries ±10% tolerance, while the PHE426MA5150JR05 carries ±5% tolerance. If circuit design requires tighter initial capacitance specification, the KEMET part is the appropriate selection. For applications tolerating ±10% variation, both parts are equivalent.

Q: What are the dimensional differences?

A: The DPP4S15K-F measures 15.00mm × 9.00mm with 18.00mm maximum seated height. The PHE426MA5150JR05 measures 13.00mm × 4.00mm with 9.00mm maximum seated height. Despite these differences, both use identical 10.00mm lead spacing, maintaining PCB footprint compatibility. Physical spacing on the circuit board must accommodate the taller DPP4S15K-F component.

Q: Do both parts have identical RoHS and environmental compliance?

A: Yes. Both the DPP4S15K-F and PHE426MA5150JR05 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level differs (MSL 1 for CDE versus Not Applicable for KEMET), but both are suitable for standard manufacturing handling and storage conditions.
