Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DMM2W2P2K-F are categorized based on the following substitution criteria:

Direct Equivalents maintain identical electrical specifications: 2.2 µF capacitance, ±10% tolerance, 250V DC rating, 160V AC rating, polyester metallized dielectric, -55°C to 125°C operating temperature, through-hole radial mounting, and PC pin termination. These parts differ only in physical dimensions and lead spacing while preserving all functional parameters.

Upgrade Substitutes increase the voltage rating to 400V DC (200V AC) while maintaining 2.2 µF capacitance, ±10% tolerance, identical operating temperature range, and radial through-hole mounting. These parts accommodate circuit designs requiring higher voltage margins or operating in elevated voltage environments.

Tighter Tolerance Upgrades reduce tolerance from ±10% to ±5% while maintaining 400V DC rating, 2.2 µF capacitance, and all other core specifications. These parts serve applications requiring improved capacitance accuracy.

Substitution validity is determined by:

• Identical capacitance value (2.2 µF)
• Equal or tighter tolerance specification
• Equal or higher voltage rating
• Matching dielectric material family (polyester metallized)
• Identical operating temperature range (-55°C to 125°C)
• Compatible mounting type (through-hole radial)
• Matching termination style (PC pins)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Identical Specifications:

DME2W2P2K-F (Cornell Dubilier Electronics) and B32523Q3225K000 or B32524Q3225K000 (EPCOS - TDK Electronics) provide direct electrical equivalence to the DMM2W2P2K-F. All three maintain 2.2 µF capacitance, ±10% tolerance, 250V DC rating, and -55°C to 125°C operating range. Selection between these options depends on lead spacing requirements and PCB layout constraints. DME2W2P2K-F features 0.886" lead spacing, while B32524Q3225K000 provides 1.083" spacing matching the original part. Both CDE and EPCOS parts carry Active product status and full ROHS3 compliance.

For Voltage Upgrade Applications:

DME4W2P2K-F (Cornell Dubilier Electronics) and B32524Q6225K (EPCOS - TDK Electronics) upgrade the voltage rating to 400V DC while preserving 2.2 µF capacitance and ±10% tolerance. DME4W2P2K-F maintains Active status. B32524Q6225K carries "Not For New Designs" designation, restricting its use to legacy system support or existing inventory management. Both parts maintain 1.083" lead spacing and full ROHS3 compliance.

For Tighter Tolerance and Voltage Upgrade:

B32594C6225J008 (EPCOS - TDK Electronics) combines 400V DC rating with ±5% tolerance specification, reducing capacitance variation to half that of the original part. This component features stacked dielectric construction and long-lead PC pins. Product status is Active with full ROHS3 compliance. This part is suitable for precision applications requiring both elevated voltage operation and improved capacitance accuracy.

Compliance and Regulatory Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the DMM2W2P2K-F. No additional compliance verification is required for direct substitution within equivalent voltage classes.

Frequently Asked Questions (FAQ)

Q: Can DME2W2P2K-F replace DMM2W2P2K-F in my circuit?

A: Yes. DME2W2P2K-F provides identical electrical specifications: 2.2 µF capacitance, ±10% tolerance, 250V DC rating, and -55°C to 125°C operating range. The primary difference is lead spacing: DME2W2P2K-F uses 0.886" spacing versus the original 1.083" spacing. Verify PCB pad layout compatibility before substitution.

Q: What is the difference between B32524Q3225K000 and B32523Q3225K000?

A: Both parts are EPCOS - TDK Electronics equivalents with identical electrical ratings (2.2 µF, ±10%, 250V DC). The primary distinction is lead spacing: B32524Q3225K000 provides 1.083" spacing matching the original DMM2W2P2K-F, while B32523Q3225K000 uses 0.886" spacing. Select based on PCB layout requirements.

Q: Can I use a 400V rated capacitor in place of a 250V rated capacitor?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible with circuits designed for lower voltage operation. DME4W2P2K-F and B32524Q6225K both provide 400V DC rating while maintaining 2.2 µF capacitance and ±10% tolerance. Physical dimensions may differ; verify PCB fit before substitution.

Q: What does "Not For New Designs" mean for B32524Q6225K?

A: This designation indicates the part remains available for existing inventory and legacy system support but should not be selected for new circuit designs. For new applications requiring 400V DC rating, use DME4W2P2K-F (Active status) or B32594C6225J008 (Active status with tighter ±5% tolerance).

Q: How does the ±5% tolerance of B32594C6225J008 differ from the ±10% tolerance of the original part?

A: The ±5% tolerance specification reduces the acceptable capacitance variation range to half that of ±10% tolerance parts. This tighter tolerance is suitable for applications requiring improved capacitance accuracy. B32594C6225J008 also provides 400V DC rating and stacked dielectric construction.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the DMM2W2P2K-F. No additional compliance documentation is required for direct substitution.

Q: What is the significance of "stacked" dielectric construction in B32594C6225J008?

A: Stacked dielectric construction refers to the internal capacitor design architecture. B32594C6225J008 uses stacked configuration while other parts use standard metallized construction. Both approaches achieve the specified 2.2 µF capacitance and voltage ratings. Selection depends on application-specific performance requirements and PCB space constraints.

Q: Can I substitute parts with different lead spacing on my existing PCB?

A: Lead spacing substitution requires PCB pad layout verification. Parts with 0.886" spacing (DME2W2P2K-F, B32523Q3225K000) are not interchangeable with 1.083" spacing parts (DMM2W2P2K-F, DME4W2P2K-F, B32524Q3225K000, B32524Q6225K, B32594C6225J008) without PCB modification. Confirm pad spacing before component selection.
