DMM4P22K-F Equivalent & Substitute Parts Reference

Part Overview

The DMM4P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400V DC voltage rating, designed for general-purpose applications requiring polyester metallized dielectric construction. This radial through-hole component operates across a temperature range of -55°C to 125°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

The DMM4P22K-F is classified as an Active product with 1006 units currently in stock. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, dielectric material) and mechanical compatibility (mounting type, termination style, lead spacing).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DMM4P22K-F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 400V (minimum requirement)
• Voltage Rating - AC: 200V (minimum requirement)
• Dielectric Material: Polyester, Metallized (functional equivalence)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required for PCB assembly compatibility)
• Package / Case: Radial (required for form factor compatibility)
• Termination: PC Pins (required for soldering compatibility)
• Lead Spacing: Tolerance for PCB hole pattern accommodation

Compliance Criteria:

• RoHS3 Compliance (environmental and regulatory requirement)
• REACH Status: REACH Unaffected (regulatory requirement)

Two substitute parts meet these criteria: DME4P22K-F (Cornell Dubilier Electronics) and B32522C6224K (EPCOS - TDK Electronics).

Parameter Comparison

Engineering Selection Recommendations

DME4P22K-F (Cornell Dubilier Electronics - CDE)

The DME4P22K-F qualifies as a direct electrical equivalent to the DMM4P22K-F, matching all critical electrical parameters: 0.22 µF capacitance, ±10% tolerance, 400V DC / 200V AC voltage ratings, polyester metallized dielectric, and -55°C to 125°C operating temperature range. Both components are Active products with ROHS3 compliance and REACH Unaffected status.

The DME4P22K-F exhibits reduced physical dimensions (18.50mm x 6.50mm vs. 26.00mm x 9.00mm) and lower profile height (14.50mm vs. 16.00mm), with lead spacing of 15.00mm versus 22.50mm on the main part. These dimensional differences require PCB layout verification to confirm hole pattern compatibility. The DME4P22K-F is suitable for applications where space constraints favor compact form factors.

B32522C6224K (EPCOS - TDK Electronics)

The B32522C6224K meets all electrical equivalence criteria with matching capacitance, tolerance, voltage ratings, and operating temperature range. The dielectric material is specified as polyester, polyethylene terephthalate (PET), metallized with stacked construction, providing functional equivalence to the metallized polyester dielectric of the main part.

The B32522C6224K is classified as "Not For New Designs," indicating this part is in mature or end-of-life status. This designation restricts its use to legacy system maintenance, repair, or replacement applications only. The component exhibits the smallest physical profile (18.00mm x 7.00mm, 12.50mm height) among the three options. Lead spacing of 15.00mm requires PCB layout verification for hole pattern compatibility.

Frequently Asked Questions (FAQ)

Q1: Can DME4P22K-F and B32522C6224K be used interchangeably with DMM4P22K-F in all applications?

A: Both substitute parts match the electrical specifications (0.22 µF, ±10%, 400V DC, 200V AC, -55°C to 125°C) required for functional equivalence. However, physical dimensions and lead spacing differ. The DMM4P22K-F has 22.50mm lead spacing, while both substitutes have 15.00mm lead spacing. PCB hole pattern compatibility must be verified before substitution. The B32522C6224K carries "Not For New Designs" status and is restricted to legacy applications.

Q2: What is the significance of the "Not For New Designs" status on B32522C6224K?

A: This designation indicates the B32522C6224K is in end-of-life or mature product phase. It is available for existing system maintenance and repair but should not be selected for new product development or long-term production applications. The DME4P22K-F and DMM4P22K-F, both Active status products, are appropriate for new designs.

Q3: How do the physical dimensions affect substitution decisions?

A: The DMM4P22K-F measures 26.00mm x 9.00mm with 22.50mm lead spacing. The DME4P22K-F and B32522C6224K are both smaller (approximately 18-19mm length, 6-7mm width) with 15.00mm lead spacing. These differences require verification that the PCB layout accommodates the alternative lead spacing and component footprint. Dimensional compatibility is a mechanical requirement separate from electrical equivalence.

Q4: Are all three parts RoHS3 compliant?

A: Yes. The DMM4P22K-F, DME4P22K-F, and B32522C6224K are all ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q5: What inventory considerations apply to these parts?

A: Current stock levels are: DMM4P22K-F (1006 units), DME4P22K-F (1544 units), and B32522C6224K (4433 units). Higher inventory availability does not determine suitability; selection must be based on electrical equivalence, mechanical compatibility, and product status alignment with application requirements.
