Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF4S15J is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±5% (defines acceptable capacitance range)
• Voltage Rating - DC: 400V (minimum requirement for circuit protection)
• Voltage Rating - AC: 200V (defines AC stress capability)
• Dielectric Material: Polypropylene (PP), Metallized (determines frequency response and pulse handling characteristics)

Mechanical Parameters:

• Mounting Type: Through Hole (PCB assembly compatibility)
• Package Type: Radial (physical form factor)
• Lead Spacing: 0.374" (9.50mm) (PCB footprint compatibility)
• Termination: PC Pins (solder connection method)

Environmental Parameters:

• Operating Temperature Range: -55°C to 105°C (thermal operating envelope)

Substitute parts must match all electrical, mechanical, and environmental parameters. Deviations in any parameter render a component incompatible for direct substitution.

Engineering Selection Recommendations

DPFF4S15J-F as Primary Substitute:

The DPFF4S15J-F is a direct electrical and mechanical equivalent to the DPFF4S15J. Both components share identical capacitance, voltage ratings, dielectric material, physical dimensions, and lead spacing. The DPFF4S15J-F is manufactured by the same supplier (Cornell Dubilier Electronics) within the same DPFF series.

The primary distinction between these components is product status and regulatory compliance. The DPFF4S15J-F carries an Active product status, ensuring continued availability and manufacturing support. Additionally, the DPFF4S15J-F is ROHS3 compliant, whereas the original DPFF4S15J is RoHS non-compliant. For applications subject to RoHS regulations or requiring components with current manufacturing support, the DPFF4S15J-F is the appropriate selection.

715P15356KD3 Consideration:

The part number 715P15356KD3 is listed as a substitute in the provided data; however, complete electrical and mechanical specifications for this component are not included in the input parameters. Direct substitution cannot be confirmed without verification that all critical parameters (capacitance, voltage rating, dielectric material, physical dimensions, and lead spacing) match the DPFF4S15J specification.

Frequently Asked Questions (FAQ)

Q: Can the DPFF4S15J-F be used as a direct replacement for the DPFF4S15J in existing designs?

A: Yes. The DPFF4S15J-F is electrically and mechanically equivalent to the DPFF4S15J. Both components have identical capacitance (0.015 µF), voltage ratings (400V DC / 200V AC), dielectric material (polypropylene metallized), physical dimensions (0.752" x 0.449"), and lead spacing (0.374"). The components are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between DPFF4S15J and DPFF4S15J-F?

A: The DPFF4S15J-F is the active production variant of the DPFF4S15J. The original DPFF4S15J is classified as obsolete and is RoHS non-compliant. The DPFF4S15J-F maintains identical electrical and mechanical specifications but carries Active product status and is ROHS3 compliant. For new designs and applications requiring regulatory compliance, the DPFF4S15J-F is the recommended selection.

Q: Are there any physical footprint differences between these components?

A: No. Both the DPFF4S15J and DPFF4S15J-F share identical physical dimensions (0.752" L x 0.449" W / 19.10mm x 11.40mm) and lead spacing (0.374" / 9.50mm). Both components use radial through-hole mounting with PC pin termination. PCB layouts designed for the DPFF4S15J require no modification to accommodate the DPFF4S15J-F.

Q: What applications are these capacitors designed for?

A: The DPFF4S15J and DPFF4S15J-F are specified for high-pulse and DV/DT applications. The polypropylene metallized dielectric provides low ESR and excellent pulse handling characteristics. Operating temperature range of -55°C to 105°C supports industrial and demanding environmental applications.

Q: Is the DPFF4S15J-F suitable for RoHS-regulated applications?

A: Yes. The DPFF4S15J-F is ROHS3 compliant and is suitable for applications subject to RoHS regulations. The original DPFF4S15J is RoHS non-compliant and should not be used in applications requiring RoHS compliance.

Q: What is the tolerance specification for these capacitors?

A: Both the DPFF4S15J and DPFF4S15J-F carry a ±5% tolerance specification. This tolerance defines the acceptable capacitance range as 0.01425 µF to 0.01575 µF.
