Substitute Part Grouping Explanation

Substitute parts for the DPFF4D68J-F are identified based on strict electrical and mechanical parameter equivalence. The substitution logic requires exact matching of the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 6800 pF
• Tolerance: ±5%
• Voltage Rating - DC: 400V
• Voltage Rating - AC: 200V
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -55°C ~ 105°C

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: Radial
• Termination: PC Pins

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Physical dimensions (length, width, height, and lead spacing) may vary within the radial through-hole package category provided all electrical and mechanical parameters remain equivalent. Variations in physical dimensions do not disqualify a part as a substitute when all critical parameters match.

Engineering Selection Recommendations

The B32620A4682J000 (EPCOS - TDK Electronics) is a qualified substitute for the DPFF4D68J-F based on electrical and mechanical parameter equivalence. Both parts meet the following criteria:

Electrical Equivalence: All critical electrical parameters are identical: 6800 pF capacitance, ±5% tolerance, 400V DC / 200V AC voltage ratings, polypropylene metallized dielectric, and -55°C ~ 105°C operating temperature range.

Mechanical Compatibility: Both parts are through-hole radial packages with PC pin termination, suitable for identical PCB mounting configurations.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Physical Dimensions: The B32620A4682J000 features a stacked radial construction with smaller physical dimensions (10.00mm x 4.00mm vs. 19.10mm x 10.20mm) and reduced lead spacing (7.50mm vs. 9.50mm). These dimensional differences reflect the stacked construction technology employed by EPCOS - TDK and do not affect electrical performance or functional compatibility in applications designed for radial through-hole film capacitors.

Product Status: Both parts are active in production with adequate inventory availability (779 units for DPFF4D68J-F; 2948 units for B32620A4682J000).

Frequently Asked Questions (FAQ)

Q: Can the B32620A4682J000 be used as a direct replacement for the DPFF4D68J-F?

A: Yes. Both parts meet identical electrical specifications (6800 pF, ±5%, 400V DC, 200V AC, polypropylene metallized dielectric, -55°C ~ 105°C) and are through-hole radial packages with PC pin termination. The substitute part is electrically and functionally equivalent.

Q: Why are the physical dimensions different between these two parts?

A: The B32620A4682J000 uses stacked radial construction technology, which results in a more compact form factor compared to the standard radial design of the DPFF4D68J-F. Both configurations are radial through-hole packages suitable for PCB mounting. The dimensional difference does not affect electrical performance or circuit functionality.

Q: Will the different lead spacing (9.50mm vs. 7.50mm) affect PCB compatibility?

A: Lead spacing differences require PCB layout verification. If the original design uses 9.50mm lead spacing, the PCB footprint must accommodate the 7.50mm spacing of the substitute part. PCB redesign or component placement adjustment may be necessary.

Q: Are both parts compliant with current regulations?

A: Yes. Both the DPFF4D68J-F and B32620A4682J000 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the difference between standard radial and stacked radial construction?

A: Stacked radial construction (used in the B32620A4682J000) arranges multiple capacitor elements in a compact stack, reducing overall physical dimensions while maintaining electrical performance. Standard radial construction (used in the DPFF4D68J-F) uses a single cylindrical element. Both achieve identical electrical specifications for this application.

Q: Are there any performance differences between these two parts?

A: No. Both parts are specified for identical electrical performance in high-pulse and DV/DT applications. The operating temperature range, voltage ratings, capacitance value, and tolerance are identical.

Q: Which part should be selected for new designs?

A: Selection depends on PCB layout constraints and lead spacing requirements. The B32620A4682J000 offers a more compact form factor, while the DPFF4D68J-F provides standard radial dimensions. Both are electrically equivalent and suitable for new designs.
