Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6609045-2 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage rating must equal or exceed 250VAC
• Current rating must equal or exceed 6A
• Frequency operation must support 50/60Hz
• Filter type must be single phase
• Configuration must be two stage

Mechanical Compatibility Criteria:

• Mounting type must be chassis mount
• Termination style must be quick connect
• Operating temperature range must encompass -10°C ~ 40°C
• Approval agencies must include CSA, UR, and VDE certifications

The substitute part 2-6609037-4 meets all electrical and mechanical compatibility requirements, with the additional benefit of active product status and higher current capacity.

Parameter Comparison

Engineering Selection Recommendations

The 2-6609037-4 serves as the direct substitute for the obsolete 6609045-2. Both parts maintain identical voltage, frequency, filter type, configuration, mounting type, and termination specifications. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

The 2-6609037-4 provides a 7A current rating compared to the 6A rating of the original part, representing a 16.7% increase in current capacity. This higher rating maintains full backward compatibility for applications operating at or below 6A.

Both parts carry equivalent regulatory approvals (CSA, UR, VDE) and maintain ROHS3 compliance. The substitute part is REACH Affected, whereas the original part is REACH Unaffected; however, this distinction does not affect functional substitution.

The inductance specification differs between the two parts (7.1mH versus 14.6mH), reflecting design differences in the EP series versus the U series. This parameter variation is inherent to the substitute design and does not preclude functional equivalence for general purpose EMC/EMI filtering applications.

Frequently Asked Questions (FAQ)

Q: Can the 2-6609037-4 directly replace the 6609045-2 in existing designs?

A: Yes. The substitute part maintains identical voltage rating (250VAC), frequency operation (50/60Hz), filter type (single phase), configuration (two stage), mounting type (chassis mount), and termination style (quick connect). The higher current rating (7A versus 6A) provides additional capacity margin without affecting compatibility.

Q: What is the significance of the current rating difference between the two parts?

A: The 2-6609037-4 is rated for 7A compared to the 6A rating of the 6609045-2. This higher rating ensures the substitute part operates within safe margins for applications drawing up to 6A. No derating or performance degradation occurs at the original 6A operating point.

Q: Are the regulatory approvals equivalent between the two parts?

A: Both parts carry CSA, UR, and VDE approvals, meeting identical regulatory requirements for general purpose applications. Both maintain ROHS3 compliance.

Q: What does the inductance difference indicate?

A: The inductance values (7.1mH for 6609045-2 and 14.6mH for 2-6609037-4) reflect design variations between the U series and EP series filters. Both values are within acceptable ranges for single phase EMC/EMI filtering and do not affect functional substitution for general purpose applications.

Q: Why is the original part classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The 2-6609037-4 remains in active production, providing a viable path for continued component sourcing and system support.

Q: Are there packaging differences between the two parts?

A: Both parts are supplied in bulk packaging. No packaging format changes affect installation or integration procedures.
