Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the DPFF2P22J-F are established based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Capacitance value: 0.22 µF (exact match required)
• Mounting type: Through Hole (mechanical compatibility)
• Package type: Radial (board layout compatibility)
• Lead spacing: 0.720" (18.30mm) (PCB footprint compatibility)
• Termination style: PC Pins (connection method)

Allowable Variation Parameters:

• Voltage rating (DC and AC): Substitute parts may have equal or higher voltage ratings
• Tolerance: Substitute parts may have equal or wider tolerance specifications
• Dielectric material: Alternative film materials (polyester, polypropylene) acceptable if electrical performance meets application requirements
• Operating temperature range: Substitute parts may have narrower or equal temperature ranges
• Compliance certifications: RoHS3 and REACH status must be maintained

The substitute part 225P22494YD3 meets all mandatory matching parameters and represents an acceptable alternative where higher voltage rating (400V DC vs. 250V DC) and wider tolerance (±10% vs. ±5%) are permissible within the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

DPFF2P22J-F Selection Criteria: Select the DPFF2P22J-F when the application requires polypropylene dielectric material, ±5% capacitance tolerance, and operating temperatures up to 105°C. This part is suitable for high-pulse and DV/DT applications where polypropylene's superior frequency response and low dissipation factor are required. The 250V DC rating is appropriate for standard industrial and consumer electronics applications.

225P22494YD3 Selection Criteria: Select the 225P22494YD3 (Orange Drop® 225P series) when higher voltage margin (400V DC) is required, when polyester dielectric characteristics are acceptable, or when the narrower operating temperature range (-55°C to 85°C) is compatible with the application environment. This substitute is suitable for audio applications and DC link/DC filtering circuits where the higher voltage rating provides additional safety margin. The ±10% tolerance is acceptable in applications where tighter tolerance is not critical.

Compliance Assurance: Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in regulated markets. Both parts carry Moisture Sensitivity Level 1 (Unlimited), eliminating moisture-related handling restrictions.

Physical Compatibility: Both parts share identical lead spacing (0.720" / 18.30mm) and termination style (PC Pins), ensuring PCB footprint compatibility. The substitute part is physically smaller in length and width but taller in seated height; verify clearance in the application's physical layout before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 225P22494YD3 directly replace the DPFF2P22J-F on the PCB?

A: Yes, regarding electrical connection. Both parts have identical lead spacing (0.720" / 18.30mm) and PC pin termination, so they fit the same PCB footprint. However, verify vertical clearance, as the 225P22494YD3 has a maximum seated height of 0.890" compared to 0.618" for the DPFF2P22J-F.

Q: What is the impact of the dielectric material difference (polypropylene vs. polyester)?

A: Polypropylene (DPFF2P22J-F) offers lower dissipation factor and superior frequency response, making it preferred for high-pulse and DV/DT applications. Polyester (225P22494YD3) provides good general-purpose performance and is suitable for audio and DC filtering applications. The choice depends on the specific application's frequency and pulse characteristics.

Q: Why does the substitute part have a higher voltage rating (400V vs. 250V)?

A: Higher voltage ratings provide additional safety margin and allow the part to operate in higher-voltage circuits. If your application operates at 250V DC or below, the 400V-rated substitute is acceptable and provides extra design margin. This does not negatively impact performance at lower voltages.

Q: Is the ±10% tolerance of the substitute acceptable instead of ±5%?

A: Tolerance acceptability depends on the circuit design. If the application requires tight capacitance control (±5%), the DPFF2P22J-F is required. If the circuit tolerates ±10% capacitance variation, the 225P22494YD3 is acceptable. Review the circuit schematic and design specifications to determine tolerance requirements.

Q: What is the significance of the narrower operating temperature range of the substitute (85°C vs. 105°C)?

A: The DPFF2P22J-F supports operation up to 105°C, while the 225P22494YD3 is rated to 85°C maximum. If your application requires sustained operation above 85°C, the DPFF2P22J-F is required. For applications with maximum ambient temperatures below 85°C, the substitute is acceptable.

Q: Are both parts currently in production?

A: Yes, both the DPFF2P22J-F and 225P22494YD3 are Active in product status, indicating current manufacturing and availability from Cornell Dubilier Electronics.

Q: Do both parts meet regulatory requirements for my market?

A: Both parts are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for most regulated markets. Verify specific regional requirements for your application.
