Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 03DKAW5 is determined by the following critical parameters:

• Filter Type & Configuration: Must be single-phase, single-stage EMC/EMI line filter
• Current Rating: Must support minimum 3A continuous current
• Voltage Rating: Must support 250VAC operation (115V/250VAC dual rating preferred, but 250VAC minimum acceptable)
• Frequency: Must operate at 50/60Hz
• Mounting & Termination: Must be chassis-mount with wire leads
• Compliance: Must maintain CSA, UR, and VDE certifications
• RoHS Status: Must be ROHS3 compliant

The 3EK3 manufactured by TE Connectivity Corcom Filters meets these substitution criteria with equivalent electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 03DKAW5 and 3EK3 maintain active product status with full compliance to CSA, UR, and VDE certification requirements. Selection between these parts should be based on application-specific voltage requirements and inductance specifications. The 03DKAW5 provides dual-voltage rating (115V/250VAC) with higher inductance (3.2mH), while the 3EK3 is rated for 250VAC operation with lower inductance (1.76mH). Both parts are ROHS3 compliant and suitable for general-purpose EMC/EMI filtering applications at 3A continuous current with 50/60Hz operation.

Frequently Asked Questions (FAQ)

Q: Can the 3EK3 replace the 03DKAW5 in all applications?

A: The 3EK3 is electrically and mechanically compatible for applications operating at 250VAC. Applications requiring 115VAC operation must use the 03DKAW5 due to its dual-voltage rating.

Q: What is the significance of the inductance difference between these parts?

A: The 03DKAW5 has 3.2mH inductance while the 3EK3 has 1.76mH. Both values are provided specifications for their respective designs. Inductance affects filtering characteristics and should be verified against application requirements.

Q: Are both parts certified to the same standards?

A: Yes. Both the 03DKAW5 and 3EK3 carry CSA, UR, and VDE approvals and are ROHS3 compliant, meeting equivalent regulatory requirements for general-purpose applications.

Q: What is the difference in packaging between these parts?

A: The 03DKAW5 is supplied in box packaging, while the 3EK3 is supplied in bag packaging. Both are suitable for component integration; packaging selection depends on inventory and handling requirements.

Q: Are there any temperature operating range differences?

A: Yes. The 03DKAW5 operates from -25°C to 100°C, while the 3EK3 operates from -10°C to 40°C. Applications requiring extended low-temperature operation must use the 03DKAW5.
