Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF12D47J is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution validity:

Electrical Parameters:

• Capacitance value: 4700 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 1200V (1.2kV) (exact match required)
• Voltage Rating - AC: 475V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.720" (18.30mm) (exact match required)
• Physical Dimensions: 1.299" L x 0.500" W (33.00mm x 12.70mm) (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above without deviation to ensure direct functional and physical compatibility.

Engineering Selection Recommendations

DPFF12D47J-F is the primary substitute for the obsolete DPFF12D47J. Both components are manufactured by Cornell Dubilier Electronics and maintain identical electrical and mechanical specifications across all critical parameters. The DPFF12D47J-F is classified as Active product status, ensuring continued availability and supply chain reliability. The DPFF12D47J-F achieves ROHS3 compliance, whereas the original DPFF12D47J is RoHS non-compliant. This compliance upgrade provides environmental and regulatory advantages for new designs and procurement cycles.

715P472516LD3 is listed as a substitute part number in the provided input data; however, complete electrical and mechanical parameter specifications for this component are not provided in the input documentation. Direct substitution cannot be confirmed based on available information.

Selection between available options should prioritize the DPFF12D47J-F for applications requiring active product status, regulatory compliance, and guaranteed long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the DPFF12D47J-F directly replace the DPFF12D47J in existing circuit designs?

A: Yes. The DPFF12D47J-F maintains identical electrical specifications (4700 pF, ±5%, 1200V DC, 475V AC) and mechanical specifications (radial through-hole package, 0.720" lead spacing, PC pin termination). Physical dimensions and operating temperature range are identical. Direct substitution is supported without circuit modification.

Q: What is the primary difference between DPFF12D47J and DPFF12D47J-F?

A: The DPFF12D47J-F is the active production variant with ROHS3 compliance. The original DPFF12D47J is classified as obsolete and RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Are there any compatibility concerns with PCB layout or mounting?

A: No. Both components share identical physical dimensions (1.299" L x 0.500" W), lead spacing (0.720"), and radial through-hole mounting configuration. PCB footprints and mounting procedures remain unchanged.

Q: What applications are these capacitors suitable for?

A: Both components are specified for high-pulse and DV/DT applications. The polypropylene metallized dielectric construction and 1200V DC rating support high-voltage pulse circuits and applications requiring rapid voltage transitions.

Q: Is the DPFF12D47J-F available in the same packaging format?

A: Yes. The DPFF12D47J-F is supplied in the identical radial through-hole package with PC pin termination. No packaging changes have been introduced.

Q: What is the operating temperature range for these capacitors?

A: Both the DPFF12D47J and DPFF12D47J-F operate across the temperature range of -55°C to 105°C, supporting applications in industrial and high-temperature environments.
