Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM6P22K-F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 250V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement; wider ranges acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)
• Lead Spacing: 1.083" (27.50mm) (exact match required for PCB compatibility)
• RoHS Status: ROHS3 Compliant (exact match required)

The 224MPR630K qualifies as a direct substitute based on full alignment with all mandatory parameters. Physical dimensions may vary within acceptable tolerances for through-hole radial components, provided lead spacing remains constant at 27.50mm.

Parameter Comparison

Engineering Selection Recommendations

The 224MPR630K is a direct functional equivalent to the DPM6P22K-F based on electrical and mechanical parameter alignment. Both components are manufactured within the Cornell Dubilier family, maintain ROHS3 compliance, and carry REACH Unaffected status, ensuring regulatory compatibility across industrial and commercial applications.

Selection Criteria:

1. Electrical Equivalence: Both parts deliver identical capacitance (0.22 µF), tolerance (±10%), and voltage ratings (630V DC / 250V AC). Operating temperature ranges are identical (-55°C ~ 105°C), supporting equivalent thermal performance in DC link and DC filtering circuits.

2. Mechanical Compatibility: Lead spacing is identical at 27.50mm, ensuring direct PCB footprint compatibility. The 224MPR630K features a lower profile (17.50mm seated height versus 25.00mm), which may provide advantages in space-constrained designs without compromising electrical performance.

3. Compliance and Certification: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial, automotive, and consumer electronics applications.

4. Availability: The 224MPR630K offers higher inventory availability (1387 units versus 835 units), supporting procurement continuity and reduced lead times.

5. Series Differentiation: The DPM6P22K-F belongs to the DPM series, while the 224MPR630K belongs to the MPR series. Both series are active products from Cornell Dubilier, indicating ongoing manufacturer support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 224MPR630K be used as a direct replacement for the DPM6P22K-F on existing PCBs?

A: Yes. The 224MPR630K is electrically and mechanically equivalent. Both components share identical lead spacing (27.50mm), termination type (PC Pins), and mounting configuration (through-hole radial). The substitute's lower profile (17.50mm versus 25.00mm) does not affect PCB compatibility and may provide clearance advantages in compact layouts.

Q: Are there any electrical performance differences between these two parts?

A: Both parts meet identical electrical specifications: 0.22 µF capacitance, ±10% tolerance, 630V DC rating, and -55°C ~ 105°C operating range. The 224MPR630K provides documented ESR data (804 mOhms), which is not specified for the DPM6P22K-F. This additional specification does not indicate performance variation but rather enhanced documentation for the substitute part.

Q: Do both parts comply with current regulatory standards?

A: Yes. Both the DPM6P22K-F and 224MPR630K are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial electronics applications.

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

A: The required lead spacing for this component category is 1.083" (27.50mm). Both the DPM6P22K-F and 224MPR630K maintain this exact spacing, ensuring PCB footprint compatibility without modification.

Q: Which part should be selected for new designs?

A: Selection between the DPM6P22K-F and 224MPR630K depends on availability and design constraints. Both are active products with equivalent electrical performance. The 224MPR630K offers higher inventory availability and a lower profile, while the DPM6P22K-F may be preferred if existing supply agreements or design documentation specify the DPM series.

Q: Are there any temperature or frequency limitations that differ between these parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 105°C) and are rated for high-frequency switching and DC filtering applications. No frequency-dependent performance differences exist between the two components.
