DMT4P22K-F Equivalent & Substitute Parts

Part Overview

The DMT4P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400V DC voltage rating and ±10% tolerance. This radial through-hole component is designed for general-purpose applications and operates across a temperature range of -55°C to 125°C. The part is currently active in production with 913 units in stock.

Equivalent and substitute parts are identified when design requirements permit component interchange due to matching electrical specifications, mechanical compatibility, and compliance certifications. Substitutes become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility allows for alternative form factors within the same electrical performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMT4P22K-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 200V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (material family match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Termination: PC Pins (exact match required)
• Lead Spacing: Compatible with 29.70mm pitch PCB layouts (primary specification); alternative lead spacings of 15.00mm are acceptable for designs with flexible PCB footprints

Compliance Requirements:

• RoHS3 Compliant (mandatory for new designs)
• REACH Unaffected (mandatory for new designs)

The identified substitute parts meet all electrical and mechanical criteria. Physical dimensions and height variations are acceptable provided the radial package configuration and lead spacing remain compatible with the target application's PCB layout.

Parameter Comparison

Engineering Selection Recommendations

DME4P22K-F (CDE): This substitute is electrically and mechanically equivalent to the DMT4P22K-F with identical electrical specifications and compliance certifications. The primary difference is the reduced physical footprint (18.50mm length vs. 33.50mm) and lead spacing (15.00mm vs. 29.70mm). The DME4P22K-F is suitable for applications where PCB space constraints permit the smaller form factor and where the 15.00mm lead spacing is compatible with the target PCB layout. Both parts are active products with full production support.

B32522C6224K (EPCOS - TDK Electronics): This substitute meets all electrical specifications and compliance requirements. However, the product status is listed as "Not For New Designs," indicating this part is in end-of-life phase. The B32522C6224K is electrically equivalent but physically smaller (18.00mm length, 12.50mm height) with 15.00mm lead spacing. This part is suitable only for legacy system maintenance or where existing PCB layouts are already committed to this form factor. New designs should prioritize the active CDE alternatives.

Selection Priority:

1. DMT4P22K-F remains the primary choice for applications requiring the 29.70mm lead spacing and larger form factor.
2. DME4P22K-F is the preferred substitute when space constraints permit the smaller package and 15.00mm lead spacing.
3. B32522C6224K is acceptable only for legacy applications or when existing inventory and PCB layouts are already established with this part number.

Frequently Asked Questions (FAQ)

Q: Can the DME4P22K-F be used as a direct replacement for the DMT4P22K-F?

A: The DME4P22K-F is electrically equivalent with identical capacitance, voltage rating, tolerance, and operating temperature specifications. However, it features a different physical form factor with reduced dimensions and 15.00mm lead spacing compared to the DMT4P22K-F's 29.70mm lead spacing. Direct substitution is possible only if the target PCB layout accommodates the 15.00mm lead spacing and smaller package dimensions.

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

A: This designation indicates the B32522C6224K is in end-of-life phase and no longer recommended for new product development. While the part remains electrically and mechanically compatible, it should be used only for maintenance of existing systems or legacy applications where the part is already established in production.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DMT4P22K-F, DME4P22K-F, and B32522C6224K are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for new designs.

Q: What is the difference in dielectric material between the CDE and EPCOS parts?

A: The DMT4P22K-F and DME4P22K-F use Polyester with Metallized construction. The B32522C6224K uses Polyester, Polyethylene Terephthalate (PET), Metallized with a Stacked configuration. Both material families are polyester-based and provide equivalent electrical performance for the specified voltage and capacitance ratings.

Q: Can I use the B32522C6224K in a new design?

A: The B32522C6224K is electrically and mechanically compatible; however, its "Not For New Designs" status indicates it is not recommended for new product development. For new designs, select either the DMT4P22K-F or DME4P22K-F, both of which are active products with full manufacturer support.

Q: What determines whether I should choose the DMT4P22K-F or DME4P22K-F?

A: The primary determining factor is PCB layout compatibility. The DMT4P22K-F has 29.70mm lead spacing and larger overall dimensions (33.50mm length). The DME4P22K-F has 15.00mm lead spacing and smaller dimensions (18.50mm length). If your PCB is designed for 29.70mm spacing, use the DMT4P22K-F. If your PCB accommodates 15.00mm spacing or if space constraints exist, the DME4P22K-F is suitable.

Q: Are there any performance differences between these three parts?

A: No. All three parts deliver identical electrical performance: 0.22 µF capacitance, ±10% tolerance, 400V DC rating, 200V AC rating, and -55°C to 125°C operating temperature range. Differences are limited to physical form factor, lead spacing, and product lifecycle status.
