Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-M2222KZ is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 2200 pF
• Tolerance: ±10%
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins

Allowable Variation Criteria:

• Voltage rating may be equal to or greater than 200V DC
• Dielectric material may be polyester or metallized polyester variants
• Operating temperature range may be equal to or exceed -40°C ~ 85°C
• Lead spacing and physical dimensions may vary within PCB layout constraints

Three substitute parts meet these criteria with varying voltage ratings and temperature performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

ECQ-E6222KF (Panasonic): This substitute provides the highest voltage rating at 630V DC with an extended operating temperature range to 105°C. As an obsolete part, it shares the same manufacturer lineage as the main component. Selection is appropriate for applications requiring elevated voltage margin and extended temperature performance within the same product family.

B32529C3222K000 (EPCOS - TDK Electronics): This substitute is classified as active product status with AEC-Q200 automotive qualification. It provides 250V DC rating with the widest operating temperature range (-55°C ~ 125°C) and metallized-stacked dielectric construction. The compact stacked radial package (7.30mm x 2.50mm) offers space optimization. This part is suitable for automotive and EMI/RFI suppression applications requiring active product support and compliance certifications.

DMT2D22K-F (Cornell Dubilier Electronics): This substitute is classified as active product status with 250V DC rating and -55°C ~ 125°C operating range. The larger radial package (13.00mm x 5.50mm) with 0.394" lead spacing accommodates applications with less stringent space constraints. Selection is appropriate for general-purpose applications prioritizing long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E6222KF be used as a direct replacement for ECQ-M2222KZ?

A: Yes. The ECQ-E6222KF maintains identical capacitance (2200 pF), tolerance (±10%), mounting type (through hole radial), and termination (PC pins). The higher voltage rating (630V vs. 200V) and extended temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C) provide additional performance margin. Lead spacing is not specified for the ECQ-E6222KF; verify PCB layout compatibility before implementation.

Q: What is the primary difference between B32529C3222K000 and DMT2D22K-F?

A: Both parts provide 250V DC rating and ±10% tolerance. The B32529C3222K000 uses a compact stacked radial package (7.30mm x 2.50mm) with 5.00mm lead spacing and includes AEC-Q200 automotive qualification. The DMT2D22K-F uses a larger standard radial package (13.00mm x 5.50mm) with 10.00mm lead spacing. Selection depends on PCB layout constraints and application requirements.

Q: Are all substitute parts RoHS compliant?

A: ECQ-E6222KF, B32529C3222K000, and DMT2D22K-F are all ROHS3 compliant. The original ECQ-M2222KZ compliance status is not specified in the provided data.

Q: Which substitute part is recommended for new designs?

A: B32529C3222K000 and DMT2D22K-F are both active products with current manufacturer support. B32529C3222K000 is recommended for space-constrained applications with automotive requirements. DMT2D22K-F is recommended for general-purpose applications with standard PCB layouts.

Q: Can these parts be used interchangeably on the same PCB?

A: Physical dimensions and lead spacing vary among substitutes. ECQ-E6222KF and B32529C3222K000 have 5.00mm or unspecified lead spacing, while DMT2D22K-F has 10.00mm lead spacing. PCB layout verification is required before selecting a substitute to ensure pad spacing and component height compatibility.
