DPP4S47K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPP4S47K-F is a 0.047 µF metallized polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial through-hole component operates at 400V DC with ±10% tolerance and is designed for high-frequency and switching applications. The part maintains Active product status with 775 units currently in stock. Substitute parts are identified when equivalent capacitance, tolerance, dielectric material, and mounting configuration are available from alternative manufacturers, particularly when higher voltage ratings or different thermal operating ranges are required for specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPP4S47K-F is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.787" (20.00mm) (exact match required)
• Termination: PC Pins (exact match required)

Secondary Compatibility Parameters:

• Voltage rating: Equal to or greater than 400V DC
• Operating temperature range: Must encompass or exceed -55°C ~ 105°C
• RoHS compliance: ROHS3 Compliant (required)
• REACH status: REACH Unaffected (required)

The QXT2J473KRPT from Nichicon qualifies as a substitute part because it maintains all primary matching criteria while providing enhanced voltage ratings (630V DC) and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

DPP4S47K-F Selection Criteria: The DPP4S47K-F is the primary choice for applications requiring the full operating temperature range of -55°C to 105°C. This part is suitable for circuits operating at or below 400V DC with 250V AC specifications. The component maintains Active product status with established supply availability (775 units in stock). ROHS3 compliance and REACH Unaffected status confirm regulatory alignment for industrial and commercial applications.

QXT2J473KRPT Selection Criteria: The QXT2J473KRPT serves as a substitute when higher voltage margins are required (630V DC / 300V AC rating). This Nichicon component is appropriate for circuits where voltage derating or future design headroom is necessary. The substitute part maintains identical capacitance, tolerance, dielectric material, and lead spacing. However, the operating temperature range is limited to -40°C to 105°C, making it unsuitable for applications requiring the full -55°C lower temperature specification. Physical dimensions differ slightly, with the substitute measuring 0.858" in seated height compared to 0.748" for the original part; PCB layout verification is required to confirm clearance compatibility. Both parts maintain ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the QXT2J473KRPT directly replace the DPP4S47K-F in all applications?

A: The QXT2J473KRPT is electrically compatible for capacitance, tolerance, and dielectric specifications. However, two factors require evaluation: (1) The operating temperature range is narrower (-40°C to 105°C versus -55°C to 105°C), so applications requiring operation below -40°C cannot use the substitute. (2) The seated height is 0.858" compared to 0.748", requiring verification that PCB layout and component clearances accommodate the additional 0.110" height.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on exact matching of capacitance (0.047 µF), tolerance (±10%), dielectric material (Polypropylene Metallized), mounting type (Through Hole), package configuration (Radial), lead spacing (0.787"), and termination type (PC Pins). The substitute voltage rating must equal or exceed the original specification. Both parts must maintain ROHS3 compliance and REACH Unaffected status.

Q: Why does the QXT2J473KRPT have a higher voltage rating?

A: The higher voltage rating (630V DC versus 400V DC) reflects the Nichicon QXT series design specifications. This higher rating provides additional voltage margin and may be beneficial in applications subject to transient overvoltage conditions or where design derating practices are implemented.

Q: Are there physical installation differences between these parts?

A: Yes. The QXT2J473KRPT is 0.110" taller when seated (0.858" versus 0.748"). The length and width dimensions also differ slightly (24.00mm x 10.50mm versus 26.00mm x 9.00mm). PCB layout must be verified to ensure adequate clearance above the component and sufficient spacing from adjacent components.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DPP4S47K-F and QXT2J473KRPT are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for industrial and commercial electronic applications.

Q: What is the inventory status for each part?

A: The DPP4S47K-F has 775 units in stock. The QXT2J473KRPT has 857 units in stock. Both parts are listed as Active products with established supply availability.
