DME10P22K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME10P22K is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DME series. This radial through-hole component is rated for 1000V DC and 250V AC operation with polyester metallized dielectric construction. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing system maintenance and new design implementations where this specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME10P22K is determined by strict equivalence across all electrical and mechanical parameters. The substitute must maintain identical specifications in the following critical areas:

Electrical Parameters:

• Capacitance value: 0.22 µF
• Tolerance: ±10%
• Voltage rating: 1000V DC / 250V AC
• Dielectric type: Polyester, Metallized

Mechanical Parameters:

• Mounting configuration: Through Hole Radial
• Lead spacing: 0.886" (22.50mm)
• Physical dimensions: 1.024" L x 0.472" W (26.00mm x 12.00mm)
• Termination type: PC Pins

The DME10P22K-F qualifies as a direct substitute based on complete parameter alignment across all specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DME10P22K-F is the direct equivalent substitute for the obsolete DME10P22K. Both parts are manufactured by Cornell Dubilier Electronics within the DME series and share identical electrical and mechanical specifications.

Key Differentiation:

The primary distinction between the two parts is product status and regulatory compliance. The original DME10P22K is classified as obsolete and does not meet RoHS3 compliance requirements. The DME10P22K-F is an active product that maintains full ROHS3 compliance while preserving all functional and dimensional characteristics of the original specification.

For applications requiring the 0.22 µF, 1000V DC polyester metallized film capacitor in radial through-hole configuration, the DME10P22K-F provides direct functional replacement with the added benefit of current manufacturing status and modern regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the DME10P22K-F be used as a direct replacement for the DME10P22K in existing designs?

A: Yes. The DME10P22K-F is electrically and mechanically identical to the DME10P22K. All electrical parameters (capacitance, voltage rating, tolerance, dielectric type) and mechanical parameters (dimensions, lead spacing, mounting configuration) are equivalent. Direct substitution is appropriate for PCB assembly and circuit operation.

Q: What is the difference between the DME10P22K and DME10P22K-F?

A: The parts are functionally identical. The primary differences are: (1) Product Status—DME10P22K is obsolete while DME10P22K-F is active; (2) RoHS Compliance—DME10P22K is non-compliant while DME10P22K-F meets ROHS3 requirements; (3) Packaging—DME10P22K uses standard packaging while DME10P22K-F is supplied in bulk packaging.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 1.024" L x 0.472" W (26.00mm x 12.00mm) with a maximum seated height of 0.906" (23.00mm). Lead spacing is 0.886" (22.50mm) for both variants. PCB layout and mechanical fit are identical.

Q: Does the DME10P22K-F meet current regulatory requirements?

A: The DME10P22K-F is ROHS3 compliant and REACH unaffected. The original DME10P22K does not meet RoHS compliance. For applications subject to RoHS requirements, the DME10P22K-F is the appropriate selection.

Q: What is the operating temperature range for these capacitors?

A: Both the DME10P22K and DME10P22K-F operate across the temperature range of -55°C to 125°C, supporting applications in industrial and demanding thermal environments.

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

A: The DME10P22K-F has higher current inventory availability (1715 pcs) compared to the obsolete DME10P22K (1011 pcs). For new designs and ongoing procurement, the DME10P22K-F is the recommended selection based on active product status and supply continuity.
