DPFF4S22J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF4S22J-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPFF series. This radial polypropylene metallized capacitor is rated for 400V DC operation with ±5% tolerance and operates across the temperature range of -55°C to 105°C. The part is currently Active in product status with 900 units in stock.

Film capacitors in this specification are essential components in high-pulse and DV/DT applications requiring stable capacitance and low ESR characteristics. Equivalent and substitute parts are identified based on matching electrical parameters (capacitance value, voltage rating, tolerance) and mechanical compatibility (radial mounting, through-hole termination, lead spacing).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF4S22J-F are identified through strict alignment with the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.022 µF (exact match required)
• Tolerance: ±5% (matching specification)
• Voltage Rating - DC: 400V minimum (equal or higher acceptable)
• Voltage Rating - AC: 200V minimum (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (required for performance characteristics)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole, Radial (required for PCB assembly)
• Termination: PC Pins (required for soldering compatibility)
• Lead Spacing: 0.374" (9.50mm) or compatible spacing for footprint fit

Compliance Criteria:

• RoHS3 Compliant status
• REACH Unaffected status

Three substitute parts meet these criteria with variations in physical dimensions and product status.

Parameter Comparison

Engineering Selection Recommendations

B32620A4223J000 and B32621A4223J000 (EPCOS-TDK Electronics)

Both EPCOS-TDK parts are Active products with full RoHS3 and REACH compliance. They provide electrical equivalence with identical capacitance (0.022 µF), tolerance (±5%), voltage ratings (400V DC / 200V AC), and operating temperature range (-55°C to 105°C) as the DPFF4S22J-F. The stacked metallized polypropylene construction delivers equivalent performance in high-pulse and DV/DT applications.

The primary difference is physical dimension and lead spacing. B32620A4223J000 features 0.295" (7.50mm) lead spacing with compact dimensions (0.394" x 0.197"), while B32621A4223J000 provides 0.394" (10.00mm) lead spacing with slightly larger dimensions (0.512" x 0.197"). Selection between these two depends on PCB footprint requirements. Both are suitable for direct electrical substitution where space constraints or lead spacing compatibility permits.

715P22356KD3 (Vishay Sprague Orange Drop® 715P Series)

The 715P22356KD3 provides electrical equivalence with identical capacitance, tolerance, and AC voltage rating. It features a higher DC voltage rating of 600V compared to the 400V specification of the DPFF4S22J-F, making it suitable for applications with voltage margin requirements. The part is RoHS3 compliant and REACH unaffected.

However, the 715P22356KD3 is classified as Obsolete in product status, indicating discontinued manufacturing. The operating temperature range is limited to -55°C to 85°C, which is narrower than the DPFF4S22J-F specification (-55°C to 105°C). Physical dimensions differ significantly (0.480" Dia x 0.902" L), and lead spacing matches at 0.374" (9.50mm). This part is suitable for substitution only in applications where the reduced upper temperature limit is acceptable and where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can B32620A4223J000 or B32621A4223J000 be used as direct replacements for DPFF4S22J-F?

A: Both EPCOS-TDK parts are electrically equivalent with matching capacitance (0.022 µF), tolerance (±5%), voltage ratings (400V DC / 200V AC), and operating temperature range (-55°C to 105°C). Direct substitution is valid from an electrical standpoint. However, physical dimensions and lead spacing differ. B32620A4223J000 has 7.50mm lead spacing versus the original 9.50mm, while B32621A4223J000 has 10.00mm lead spacing. PCB footprint compatibility must be verified before substitution.

Q: What is the difference between the two EPCOS-TDK substitute parts?

A: B32620A4223J000 and B32621A4223J000 differ only in physical dimensions and lead spacing. B32620A4223J000 is more compact (10.00mm x 5.00mm) with 7.50mm lead spacing, while B32621A4223J000 is larger (13.00mm x 5.00mm) with 10.00mm lead spacing. Both deliver identical electrical performance. Selection depends on available PCB space and existing footprint design.

Q: Why is 715P22356KD3 listed as Obsolete?

A: The 715P22356KD3 is classified as Obsolete, indicating that Vishay Sprague has discontinued manufacturing this part. While it remains electrically compatible with the DPFF4S22J-F, long-term availability cannot be assured. This part should be considered only when existing inventory is confirmed available and when the reduced operating temperature range (-55°C to 85°C) is acceptable for the application.

Q: Does the higher voltage rating of 715P22356KD3 (600V) provide any advantage?

A: The 715P22356KD3 features a 600V DC rating compared to the 400V DC specification of DPFF4S22J-F. This higher rating provides additional voltage margin in applications subject to transient overvoltage conditions. However, this advantage must be weighed against the Obsolete product status and narrower operating temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. DPFF4S22J-F, B32620A4223J000, B32621A4223J000, and 715P22356KD3 are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of "stacked" construction in the EPCOS-TDK parts?

A: The EPCOS-TDK B3262* series uses stacked metallized polypropylene construction, which differs from the standard radial configuration of the DPFF4S22J-F. Stacked construction allows for more compact physical dimensions while maintaining electrical performance. This construction method is standard for the EPCOS-TDK MKP High Pulse series and does not affect electrical compatibility or performance in high-pulse and DV/DT applications.

Q: Can lead spacing differences affect PCB assembly?

A: Yes. Lead spacing directly determines PCB footprint compatibility. The DPFF4S22J-F uses 9.50mm lead spacing. B32620A4223J000 (7.50mm) and B32621A4223J000 (10.00mm) have different spacing. While 715P22356KD3 matches at 9.50mm, physical body dimensions differ significantly. PCB layout must accommodate the selected substitute part's lead spacing and body dimensions to ensure proper soldering and mechanical stability.
