Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF6D47J-F are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 4700 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 630V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -55°C minimum and 105°C maximum (substitute must meet or exceed)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowed Variation Parameters:

• Voltage Rating - AC: May vary (200V, 250V, or 400V acceptable)
• Physical dimensions: May vary within radial package constraints
• Lead spacing: May vary within through-hole compatibility range
• Series designation: May differ between manufacturers
• Moisture Sensitivity Level: May differ

Three substitute parts meet these criteria: B32620A6472J000 and B32621A6472J000 from EPCOS - TDK Electronics (B3262* series), and R76PD1470SE40J from KEMET (R76 series).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and full compliance with RoHS3 and REACH requirements, matching the DPFF6D47J-F baseline. Selection between substitutes depends on application-specific constraints:

B32620A6472J000 and B32621A6472J000 (EPCOS - TDK Electronics): Both parts feature stacked metallized polypropylene construction within the B3262* MKP High Pulse series. These substitutes provide 400V AC rating compared to the main part's 200V AC rating. The B32620A6472J000 offers the most compact footprint (10.00mm L x 4.00mm W, 7.50mm lead spacing), while B32621A6472J000 provides intermediate dimensions (13.00mm L x 4.00mm W, 10.00mm lead spacing). Both maintain the 630V DC rating and ±5% tolerance specification.

R76PD1470SE40J (KEMET): This substitute from the R76 series provides 250V AC rating and extends the upper operating temperature to 110°C. The part carries AEC-Q200 automotive qualification and is designated for automotive, high frequency switching, and high pulse applications. Physical dimensions match the B32620A6472J000 (10.00mm L x 4.00mm W, 7.50mm lead spacing).

All substitutes are electrically and mechanically compatible with the DPFF6D47J-F for applications requiring 4700 pF capacitance at 630V DC with ±5% tolerance and through-hole radial mounting.

Frequently Asked Questions (FAQ)

Q: Can B32620A6472J000 or B32621A6472J000 be used as direct replacements for DPFF6D47J-F?

A: Yes. Both EPCOS parts meet all mandatory electrical and mechanical parameters: 4700 pF capacitance, ±5% tolerance, 630V DC rating, polypropylene metallized dielectric, -55°C to 105°C operating range, through-hole radial mounting with PC pins, and RoHS3 compliance. The stacked construction and higher AC voltage rating (400V vs. 200V) represent design improvements. Physical dimensions differ but remain compatible with standard through-hole PCB layouts.

Q: What is the difference between the two EPCOS substitutes?

A: B32620A6472J000 and B32621A6472J000 differ in physical dimensions and lead spacing. B32620A6472J000 measures 10.00mm L x 4.00mm W with 7.50mm lead spacing, while B32621A6472J000 measures 13.00mm L x 4.00mm W with 10.00mm lead spacing. Both deliver identical electrical performance. Selection depends on available PCB space and lead spacing requirements.

Q: Is R76PD1470SE40J suitable for automotive applications?

A: R76PD1470SE40J carries AEC-Q200 automotive qualification and is designated for automotive applications. It meets all electrical specifications of the DPFF6D47J-F and extends the upper operating temperature to 110°C. This substitute is appropriate for automotive-grade circuit designs requiring 4700 pF at 630V DC.

Q: Do the substitute parts have different moisture sensitivity levels?

A: B32620A6472J000, B32621A6472J000, and R76PD1470SE40J are all classified as Not Applicable for Moisture Sensitivity Level, compared to the DPFF6D47J-F which is rated MSL 1 (Unlimited). This indicates the substitute parts do not require moisture-sensitive device handling procedures.

Q: Can these substitutes be used interchangeably in high pulse and DV/DT applications?

A: Yes. All three substitute parts are rated for High Pulse and DV/DT applications, matching the DPFF6D47J-F application profile. The stacked construction of the EPCOS parts and the automotive qualification of the KEMET part provide additional design margins for demanding pulse and switching environments.
