Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity Corcom Filters model 6609037-1 qualifies as a manufacturer-recommended substitute based on the following critical parameters:

• Filter Type: Both are single-phase EMC/EMI line filters
• Configuration: Both feature two-stage design
• Current Rating: Both rated at 3A
• Frequency: Both operate at 50/60Hz
• Mounting: Both are chassis-mount with quick-connect termination
• Compliance: Both hold CSA, UR, and VDE approvals
• RoHS Status: Both are ROHS3 compliant

The primary operational difference is voltage rating: the Qualtek 870-03/001 supports dual voltage (115V/250VAC), while the TE Connectivity 6609037-1 is rated for 250VAC only. This distinction determines application suitability based on system voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status with full regulatory compliance. Selection between the Qualtek 870-03/001 and TE Connectivity 6609037-1 is determined by system voltage requirements:

• Qualtek 870-03/001: Select for applications requiring dual-voltage operation (115V or 250VAC) or operating environments with temperature extremes reaching -25°C or exceeding 40°C.

• TE Connectivity 6609037-1: Select for 250VAC-only applications where the narrower operating temperature range (-10°C ~ 40°C) is acceptable. This part offers higher inventory availability (2524 pcs vs. 712 pcs).

Both parts carry identical regulatory approvals (CSA, UR, VDE) and RoHS3 compliance status, ensuring equivalent electromagnetic compatibility performance in two-stage filtering architecture.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6609037-1 be used in a 115VAC system?

A: No. The TE Connectivity 6609037-1 is rated for 250VAC only. For 115VAC applications, the Qualtek 870-03/001 is required.

Q: Are the quick-connect terminations identical between these parts?

A: Both parts feature quick-connect termination style. Physical connector compatibility must be verified against your specific application interface requirements.

Q: What is the temperature operating range difference?

A: The Qualtek 870-03/001 operates from -25°C to 85°C, while the TE Connectivity 6609037-1 operates from -10°C to 40°C. Select based on your application's thermal environment.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts hold CSA, UR, and VDE approvals and are ROHS3 compliant.

Q: What is the inductance value for the TE Connectivity 6609037-1?

A: The inductance specification for the TE Connectivity 6609037-1 is not provided in the technical data.

Q: Which part should I select for general procurement?

A: Selection depends on your system voltage requirement. For 250VAC-only systems within the -10°C to 40°C temperature range, the TE Connectivity 6609037-1 offers higher inventory availability. For dual-voltage capability or extended temperature operation, select the Qualtek 870-03/001.
