Part Overview

The DPFF6S22J-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial polypropylene metallized capacitor operates at 630V DC with ±5% tolerance and is rated for high pulse and DV/DT applications. The part is currently active in production with 721 units in stock. Equivalent and substitute parts are identified for applications requiring compatible electrical and mechanical specifications, particularly when the primary part becomes unavailable or when design requirements necessitate alternative form factors or voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF6S22J-F is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 0.022 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins

Secondary Compatibility Parameters:

• Voltage rating - DC: 630V minimum (equal or higher acceptable)
• Voltage rating - AC: 200V minimum (equal or higher acceptable)
• Operating temperature range: -55°C ~ 105°C minimum (equal or wider acceptable)
• Lead spacing: 0.374" (9.50mm) or 0.394" (10.00mm) (minor variation acceptable for through-hole mounting)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Substitute parts must satisfy all primary criteria and maintain compatibility with secondary parameters to ensure functional equivalence in high pulse and DV/DT applications.

Engineering Selection Recommendations

B32621A6223J000 (EPCOS - TDK Electronics) - Primary Substitute

The B32621A6223J000 is the preferred substitute for the DPFF6S22J-F. Both parts are active products with identical capacitance (0.022 µF), tolerance (±5%), and DC voltage rating (630V). Both operate across the full temperature range of -55°C ~ 105°C and maintain ROHS3 compliance. The B32621A6223J000 features a stacked radial construction with a more compact footprint (13.00mm x 6.00mm versus 24.10mm x 14.00mm), making it suitable for space-constrained applications. The lead spacing of 0.394" (10.00mm) is compatible with standard through-hole PCB layouts. The higher AC voltage rating (400V versus 200V) provides additional design margin. Inventory availability is significantly higher at 4913 units.

715P22356KD3 (Vishay Sprague Orange Drop® 715P) - Secondary Substitute

The 715P22356KD3 is a functional equivalent with matching capacitance (0.022 µF), tolerance (±5%), and AC voltage rating (200V). However, this part is obsolete and carries a reduced DC voltage rating of 600V compared to the 630V specification of the DPFF6S22J-F. The operating temperature range is limited to -55°C ~ 85°C, which does not extend to the full 105°C upper limit. The larger radial form factor (12.20mm diameter x 22.90mm length) requires greater board space. This part is suitable only for applications where the 600V DC rating is acceptable and operating temperatures remain below 85°C. Use is not recommended for new designs due to obsolete status.

Frequently Asked Questions (FAQ)

Q: Can the B32621A6223J000 be used as a direct replacement for the DPFF6S22J-F?

A: Yes. Both parts share identical capacitance (0.022 µF), tolerance (±5%), and DC voltage rating (630V). The B32621A6223J000 operates across the same temperature range (-55°C ~ 105°C) and maintains ROHS3 compliance. The primary difference is the stacked radial construction, which results in a more compact footprint. Lead spacing is compatible with standard through-hole PCB layouts.

Q: What are the key differences between the DPFF6S22J-F and the 715P22356KD3?

A: The 715P22356KD3 has a lower DC voltage rating (600V versus 630V) and a restricted operating temperature range (-55°C ~ 85°C versus -55°C ~ 105°C). The part is also obsolete. The radial form factor is larger, requiring more board space. Substitution is acceptable only in applications where the reduced voltage and temperature specifications are compatible with circuit requirements.

Q: Does lead spacing variation affect PCB compatibility?

A: The DPFF6S22J-F and 715P22356KD3 both use 0.374" (9.50mm) lead spacing, which is standard for radial film capacitors. The B32621A6223J000 uses 0.394" (10.00mm) lead spacing. This minor variation (0.020" or 0.50mm) is within tolerance for standard through-hole PCB designs and does not prevent board-level substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The DPFF6S22J-F, 715P22356KD3, and B32621A6223J000 are all ROHS3 compliant, ensuring regulatory alignment for applications subject to RoHS requirements.

Q: Which substitute part offers the best availability?

A: The B32621A6223J000 has the highest inventory level at 4913 units in stock, compared to 721 units for the DPFF6S22J-F and 790 units for the 715P22356KD3. The B32621A6223J000 is also an active product, ensuring continued availability for future procurement.

Q: Can the 715P22356KD3 be used in high-temperature applications?

A: No. The 715P22356KD3 is rated only to 85°C maximum operating temperature, which is 20°C below the DPFF6S22J-F specification of 105°C. Applications requiring operation above 85°C must use the DPFF6S22J-F or B32621A6223J000.

Q: What is the significance of the stacked radial construction in the B32621A6223J000?

A: The stacked radial design allows for a more compact physical footprint while maintaining the same electrical specifications. This construction is particularly beneficial in space-constrained applications where board real estate is limited. The stacked configuration does not affect electrical performance or reliability for high pulse and DV/DT applications.
