DPFF6P22J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF6P22J-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 630V DC operation with polypropylene metallized dielectric. This radial through-hole component is designed for high-pulse and DV/DT applications requiring stable capacitance and low ESR characteristics. The part maintains Active product status with 822 units currently in stock.

Substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining functional compatibility within the application circuit. Substitution becomes necessary when the primary part reaches end-of-life, inventory constraints occur, or alternative sourcing improves supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF6P22J-F is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Capacitance value: 0.22 µF (exact match required)
• Dielectric type: Polypropylene (PP), Metallized (exact match required)
• Tolerance: ±5% (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 1.094 inches / 27.80 mm (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: May be equal to or greater than 630V
• Voltage Rating - AC: May be equal to or greater than 200V
• Operating Temperature Range: May be equal to or encompass the -55°C ~ 105°C range
• Physical dimensions: May vary within PCB layout constraints
• Manufacturer: Alternative qualified manufacturers permitted

The substitute part 715P22456MD3 meets all critical matching parameters. The DC voltage rating of 600V is lower than the primary part's 630V specification; therefore, this substitute is suitable only for applications where the circuit design voltage requirement does not exceed 600V DC.

Engineering Selection Recommendations

Primary Part Selection (DPFF6P22J-F): Select the DPFF6P22J-F when circuit design specifications require 630V DC voltage rating and operating temperatures up to 105°C. This part is Active status with established supply (822 units in stock) and carries full ROHS3 compliance and REACH Unaffected certification.

Substitute Part Selection (715P22456MD3): The 715P22456MD3 substitute is suitable for applications where:

• Circuit design voltage requirement does not exceed 600V DC
• Operating temperature does not exceed 85°C
• PCB layout accommodates the physical dimensions (0.831" Dia x 1.650" L vs. 1.701" L x 0.850" W)

Both parts maintain identical capacitance, tolerance, dielectric material, lead spacing, and regulatory compliance status. The substitute part is Active status with higher inventory availability (1,713 units in stock).

Voltage Derating Consideration: The 715P22456MD3 operates at 600V DC maximum, which represents a 30V reduction from the DPFF6P22J-F specification. Applications operating near the 630V specification limit of the primary part cannot use this substitute without circuit redesign.

Temperature Derating Consideration: The 715P22456MD3 maximum operating temperature is 85°C, compared to 105°C for the primary part. Applications requiring sustained operation above 85°C require the DPFF6P22J-F.

Frequently Asked Questions (FAQ)

Q: Can the 715P22456MD3 be used as a direct replacement for DPFF6P22J-F in all applications?

A: No. The 715P22456MD3 has a lower DC voltage rating (600V vs. 630V) and narrower operating temperature range (-55°C ~ 85°C vs. -55°C ~ 105°C). Substitution is valid only when the circuit design voltage does not exceed 600V DC and operating temperature does not exceed 85°C.

Q: What is the physical size difference between these two parts?

A: DPFF6P22J-F dimensions are 1.701" L x 0.850" W (43.20mm x 21.60mm). The 715P22456MD3 dimensions are 0.831" Dia x 1.650" L (21.10mm x 41.90mm). Both maintain identical lead spacing of 1.094" (27.80 mm), ensuring PCB footprint compatibility. Physical envelope differences must be verified against PCB layout constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both DPFF6P22J-F and 715P22456MD3 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What applications are these capacitors designed for?

A: The DPFF6P22J-F is specified for high-pulse and DV/DT applications. The 715P22456MD3 is specified for audio, high-frequency switching, high-pulse, DV/DT, and snubber applications. Both are polypropylene metallized film capacitors suitable for demanding electrical environments.

Q: Can I use the substitute part if my circuit operates at exactly 600V DC?

A: The 715P22456MD3 is rated for 600V DC maximum. Operating at the maximum rated voltage without design margin is not recommended for critical applications. Verify that circuit design includes appropriate voltage derating and that peak transient voltages do not exceed 600V.

Q: What is the lead spacing requirement, and do both parts meet it?

A: Both parts have identical lead spacing of 1.094 inches (27.80 mm), which is the critical PCB footprint parameter. This ensures both parts fit the same through-hole PCB layout without modification.

Q: Are there inventory considerations for selecting between these parts?

A: The DPFF6P22J-F has 822 units in stock. The 715P22456MD3 has 1,713 units in stock. If substitution parameters are met, the 715P22456MD3 offers higher inventory availability for immediate fulfillment.
