Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF4S33J-F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.033 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 400V (minimum requirement)
• Voltage Rating - AC: 200V (minimum requirement)
• Dielectric Material: Polypropylene (PP), Metallized (required for application compatibility)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required for PCB assembly compatibility)
• Package / Case: Radial (required for footprint compatibility)
• Termination: PC Pins (required for soldering compatibility)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Product Status: Active (availability and support requirement)

All three substitute parts meet these criteria. Physical dimensions and lead spacing may vary within acceptable limits for through-hole radial capacitors, provided the component fits within the designated PCB footprint area.

Engineering Selection Recommendations

DPFF4S33J-F (Main Part) Select this part when CDE DPFF series availability and specifications are required. Operating temperature range extends to 105°C. Inventory: 725 Pcs.

715P33354KD3 (CDE Orange Drop® 715P Series) This substitute is suitable for applications where CDE Orange Drop® series is specified. Operating temperature range is limited to 85°C, which is acceptable for most standard industrial applications. Higher inventory availability (4034 Pcs) supports extended production runs. Lead spacing and physical dimensions differ from the main part; verify PCB footprint compatibility before selection.

B32620A4333J000 (EPCOS - TDK Electronics B3262 Series)* This substitute uses stacked radial construction and is qualified for high pulse and DV/DT applications. Operating temperature range extends to 105°C, matching the main part. Compact physical dimensions (10.30mm L x 6.00mm W) may provide space advantages in constrained layouts. Lead spacing of 7.50mm differs from the main part; verify PCB footprint compatibility.

B32621A4333J000 (EPCOS - TDK Electronics B3262 Series)* This substitute uses stacked radial construction and is qualified for high pulse and DV/DT applications. Operating temperature range extends to 105°C. Highest inventory availability (15273 Pcs) supports large-scale production requirements. Physical dimensions (13.00mm L x 5.00mm W) and lead spacing of 10.00mm differ from the main part; verify PCB footprint compatibility.

All substitute parts maintain electrical equivalence and regulatory compliance. Selection depends on availability, physical footprint constraints, and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 715P33354KD3 be used in applications requiring 105°C operation? A: No. The 715P33354KD3 operating temperature range is -55°C to 85°C, which is lower than the main part DPFF4S33J-F (-55°C to 105°C). For applications requiring 105°C operation, select B32620A4333J000 or B32621A4333J000.

Q: Are the physical dimensions interchangeable between all substitute parts? A: No. Physical dimensions vary across the substitute parts. The DPFF4S33J-F measures 24.10mm L x 12.70mm W. The 715P33354KD3 measures 9.70mm Dia x 22.90mm L. The B32620A4333J000 measures 10.30mm L x 6.00mm W. The B32621A4333J000 measures 13.00mm L x 5.00mm W. PCB footprint and lead spacing must be verified for each substitute before selection.

Q: Do all substitute parts have the same lead spacing? A: No. The DPFF4S33J-F and 715P33354KD3 both have 0.374" (9.50mm) lead spacing. The B32620A4333J000 has 0.295" (7.50mm) lead spacing. The B32621A4333J000 has 0.394" (10.00mm) lead spacing. PCB design must accommodate the selected part's lead spacing.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts (715P33354KD3, B32620A4333J000, B32621A4333J000) are ROHS3 compliant, matching the main part DPFF4S33J-F.

Q: What is the difference between standard radial and stacked radial construction? A: The DPFF4S33J-F and 715P33354KD3 use standard radial construction. The B32620A4333J000 and B32621A4333J000 use stacked radial construction, which provides a more compact form factor. Both construction types are electrically equivalent for the specified capacitance, voltage, and tolerance values.

Q: Can I substitute based on capacitance value alone? A: No. Substitution requires matching capacitance (0.033 µF), tolerance (±5%), voltage ratings (400V DC / 200V AC), dielectric material (Polypropylene metallized), mounting type (Through Hole), package type (Radial), and termination (PC Pins). All electrical and mechanical parameters must align for proper circuit operation.

Q: Which substitute part has the highest inventory availability? A: B32621A4333J000 has the highest inventory with 15273 Pcs in stock, followed by 715P33354KD3 with 4034 Pcs, and B32620A4333J000 with 4065 Pcs. The main part DPFF4S33J-F has 725 Pcs available.
