DPP1S47K-F Equivalent & Substitute Parts

Part Overview

The DPP1S47K-F is a 0.047 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial polypropylene metallized capacitor is rated for 100V DC operation with ±10% tolerance and is designed for high-frequency and switching applications. The part maintains Active product status with 703 units currently in stock. Substitute parts are identified based on matching capacitance value, tolerance, dielectric material, mounting type, and operating temperature range to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPP1S47K-F is determined by the following criteria:

Primary Matching Parameters:

• 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 type: Radial (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: Equal to or greater than 100V
• Operating Temperature Range: Must encompass -55°C ~ 105°C
• Physical dimensions: May vary within industry standards for radial packages
• RoHS and REACH compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The B32621A5473K000 qualifies as a substitute because it matches all primary parameters and exceeds the voltage rating requirement (160V DC vs. 100V DC), while maintaining identical operating temperature range and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The B32621A5473K000 is functionally equivalent to the DPP1S47K-F for applications requiring 0.047 µF capacitance at 100V DC or lower. Selection between these parts should be based on the following engineering considerations:

DPP1S47K-F Selection Criteria:

• Applications requiring the original CDE DPP series form factor
• PCB layouts designed for 15.00mm lead spacing
• Designs with vertical space constraints accommodating 18.50mm seated height
• Preference for Cornell Dubilier Electronics supply chain

B32621A5473K000 Selection Criteria:

• Applications benefiting from higher voltage rating (160V DC) for design margin
• PCB layouts with 10.00mm lead spacing capability
• Space-constrained designs where compact dimensions (13.00mm x 4.00mm) are advantageous
• EPCOS - TDK Electronics supply chain preference or availability
• Applications requiring high-pulse or DV/DT performance characteristics

Both parts maintain ROHS3 Compliant and REACH Unaffected status. Both operate across the identical temperature range of -55°C to 105°C. Substitution is electrically valid when PCB layout accommodates the different physical dimensions and lead spacing of the B32621A5473K000.

Frequently Asked Questions (FAQ)

Q: Can the B32621A5473K000 directly replace the DPP1S47K-F on an existing PCB?

A: Electrical substitution is valid. However, physical substitution requires PCB layout verification. The B32621A5473K000 has different lead spacing (10.00mm vs. 15.00mm) and smaller overall dimensions. PCB hole patterns must accommodate the 10.00mm spacing, or the part cannot be mounted without modification.

Q: What does "Polypropylene (PP), Metallized - Stacked" mean for the B32621A5473K000?

A: The stacked construction refers to the internal dielectric arrangement in the B3262* series. This is a manufacturing variant of polypropylene metallized film technology. It does not affect electrical equivalence for the specified capacitance, tolerance, and voltage ratings.

Q: Are there any applications where the B32621A5473K000 cannot substitute for the DPP1S47K-F?

A: The B32621A5473K000 cannot substitute if the PCB layout is fixed to 15.00mm lead spacing or if the design requires the specific form factor of the DPP series. Additionally, if the application requires the exact CDE DPP series designation for traceability or supply chain requirements, the original part must be used.

Q: Why does the B32621A5473K000 have a higher voltage rating?

A: The higher 160V DC rating reflects the design specifications of the EPCOS B3262* series. This higher rating provides additional design margin and does not affect substitution validity for 100V DC applications. The capacitance, tolerance, and dielectric material remain identical.

Q: What is the moisture sensitivity level (MSL) difference between these parts?

A: The DPP1S47K-F has MSL 1 (Unlimited), indicating no moisture sensitivity. The B32621A5473K000 lists MSL as Not Applicable, which also indicates no moisture sensitivity concern. Both parts are suitable for standard storage and handling conditions.

Q: Can I use the B32621A5473K000 in high-frequency and switching applications?

A: Yes. The B32621A5473K000 is specified for high-pulse and DV/DT applications, which encompass high-frequency and switching use cases. Both parts use metallized polypropylene dielectric suitable for these applications.
