DPM2P22K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial through-hole component operates at 250V DC with polypropylene metallized dielectric construction. The part is designed for DC link, DC filtering, high frequency, and switching applications, featuring low ESR and low ESL characteristics. The DPM2P22K-F maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative specifications within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPM2P22K-F are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Electrical Compatibility:

• Capacitance value: 0.22 µF (exact match required)
• Voltage rating: 250V DC minimum (equal or higher acceptable)
• Dielectric material: Polypropylene (PP), Metallized (same material class)
• Operating temperature range: -55°C ~ 105°C (matching or exceeding range)

Mechanical Compatibility:

• Mounting type: Through Hole (identical)
• Package type: Radial (identical)
• Lead spacing: 0.591" (15.00mm) (exact match required for PCB compatibility)
• Termination: PC Pins (identical)

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected designation

The PHE426HB6220JR06 from KEMET meets all electrical and mechanical substitution criteria, with the exception of tolerance specification (±5% versus ±10%) and physical dimensions (height and width), which represent improvements or acceptable variations within the application scope.

Engineering Selection Recommendations

Primary Part: DPM2P22K-F (Cornell Dubilier Electronics)

The DPM2P22K-F is the specified component and maintains Active product status with full regulatory compliance. This part is suitable for direct application when CDE sourcing is preferred or contractually required.

Substitute Part: PHE426HB6220JR06 (KEMET)

The PHE426HB6220JR06 is a direct electrical and mechanical substitute for the DPM2P22K-F. This KEMET component provides identical electrical performance across all critical parameters: 0.22 µF capacitance, 250V DC rating, polypropylene metallized dielectric, and -55°C to 105°C operating range. The PHE426HB6220JR06 features a tighter tolerance specification (±5% versus ±10%), which represents an improvement in capacitance accuracy. Physical dimensions are reduced (0.217" width and 0.413" height versus 0.315" and 0.630" respectively), resulting in a smaller component footprint while maintaining identical lead spacing (15.00mm) for direct PCB compatibility. Both parts maintain ROHS3 compliance and REACH unaffected status. The PHE426HB6220JR06 is suitable for direct substitution in DC link, DC filtering, high frequency, and switching applications.

Frequently Asked Questions (FAQ)

Q: Can the PHE426HB6220JR06 be used as a direct replacement for the DPM2P22K-F on existing PCBs?

A: Yes. The PHE426HB6220JR06 maintains identical lead spacing (15.00mm) and through-hole radial mounting configuration. The component footprint is smaller in width and height, which presents no compatibility issues for PCB placement. Both parts use PC pin termination and are mechanically interchangeable.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: Tolerance specifies the allowable deviation from the nominal 0.22 µF capacitance value. The DPM2P22K-F permits deviation between 0.198 µF and 0.242 µF. The PHE426HB6220JR06 permits deviation between 0.209 µF and 0.231 µF. The tighter ±5% tolerance of the KEMET part provides greater capacitance accuracy and consistency, which may be beneficial in precision filtering or timing applications.

Q: Are both parts suitable for the same applications?

A: Yes. Both the DPM2P22K-F and PHE426HB6220JR06 are specified for DC link, DC filtering, high frequency, and switching applications. Both operate across the identical temperature range (-55°C to 105°C) and voltage ratings (250V DC, 160V AC). The KEMET part additionally supports high pulse and DV/DT applications.

Q: What are the compliance and regulatory considerations for substitution?

A: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing. No additional compliance verification is required when substituting between these parts.

Q: How do the physical dimensions affect component selection?

A: The PHE426HB6220JR06 features a reduced physical profile (0.217" width and 0.413" height) compared to the DPM2P22K-F (0.315" width and 0.630" height). This smaller footprint may provide advantages in space-constrained designs. Lead spacing remains identical at 15.00mm, ensuring PCB compatibility without layout modification.

Q: What inventory considerations apply to these parts?

A: The DPM2P22K-F has 741 pieces in stock. The PHE426HB6220JR06 has 2160 pieces in stock, providing greater availability for immediate procurement.
