Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF4S47J is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 0.047 µF
• Tolerance: ±5%
• Voltage rating: 400V DC minimum / 200V AC minimum
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.720" (18.30mm)
• Physical dimensions: 1.299" L x 0.500" W maximum
• Termination: PC Pins

Environmental Parameters:

• Operating temperature range: -55°C to 105°C minimum
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation. Parts meeting these criteria are classified as direct functional equivalents suitable for circuit-level replacement.

Engineering Selection Recommendations

DPFF4S47J-F as Primary Substitute:

The DPFF4S47J-F is a direct functional equivalent to the obsolete DPFF4S47J. Both components share identical electrical specifications, mechanical dimensions, and environmental operating parameters. The DPFF4S47J-F is manufactured by the same supplier (Cornell Dubilier Electronics) within the same DPFF series.

Compliance Advantage:

The DPFF4S47J-F carries active product status and ROHS3 compliance certification, whereas the original DPFF4S47J is obsolete and RoHS non-compliant. For new designs or equipment requiring regulatory compliance, the DPFF4S47J-F satisfies modern environmental and safety standards while maintaining full electrical and mechanical compatibility.

Supply Availability:

Current inventory status indicates 966 units of DPFF4S47J-F available in bulk packaging, compared to 704 units of the obsolete DPFF4S47J. The active status of DPFF4S47J-F ensures continued availability for production and maintenance applications.

Selection Criteria:

• For legacy equipment repair requiring exact form-fit-function replacement: DPFF4S47J-F
• For new designs or compliance-driven applications: DPFF4S47J-F
• For applications where RoHS compliance is mandatory: DPFF4S47J-F

Frequently Asked Questions (FAQ)

Q: Can DPFF4S47J-F replace DPFF4S47J in existing circuit designs?

A: Yes. The DPFF4S47J-F is electrically and mechanically identical to the DPFF4S47J across all specified parameters: 0.047 µF capacitance, ±5% tolerance, 400V DC rating, polypropylene metallized dielectric, through-hole radial mounting, and identical physical dimensions with 0.720" lead spacing. Direct substitution is supported without circuit modification.

Q: What is the difference between DPFF4S47J and DPFF4S47J-F?

A: The primary differences are product status and regulatory compliance. The DPFF4S47J is obsolete and RoHS non-compliant. The DPFF4S47J-F is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Does the packaging difference affect substitution?

A: The DPFF4S47J is supplied in standard packaging, while DPFF4S47J-F is supplied in bulk packaging. Packaging format does not affect component performance or circuit compatibility. Both deliver identical capacitor elements with identical PC pin terminations.

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate across the identical temperature range of -55°C to 105°C and maintain the same voltage ratings of 400V DC and 200V AC. No derating adjustments are required when substituting between these parts.

Q: What applications are these capacitors suitable for?

A: Both DPFF4S47J and DPFF4S47J-F are specified for high-pulse and DV/DT applications. The polypropylene metallized dielectric construction provides the electrical characteristics required for these demanding pulse and transient voltage applications.

Q: Is moisture sensitivity a concern for these capacitors?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures are sufficient; no special moisture control measures are required.

Q: Can DPFF4S47J-F be used in equipment requiring RoHS compliance?

A: Yes. The DPFF4S47J-F carries ROHS3 compliance certification, making it suitable for applications and markets requiring RoHS compliance. The original DPFF4S47J is RoHS non-compliant and should not be used in compliance-mandated applications.
