Qualtek 857-03/017 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Qualtek 857-03/017 is an AC power entry connector receptacle designed for IEC 320-C14 panel mount applications. This component features male blades, filtered EMI/RFI protection, and quick connect termination rated for 3A at 115/250VAC. The part is currently obsolete, making identification of compatible substitutes essential for maintenance, repair, and legacy system support. Equivalent parts must maintain identical electrical ratings, connector geometry, and filtering characteristics to ensure proper system operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 857-03/017 is determined by strict equivalence across the following critical parameters:

• Connector style and type (IEC 320-C14 receptacle with male blades)
• Electrical ratings (3A current, 115/250VAC minimum voltage support)
• Filtering capability (EMI/RFI commercial-grade filter at 3A)
• Mechanical interface (panel mount flange with quick connect termination)
• Panel cutout compatibility (rectangular 28.45mm x 21.59mm or equivalent)
• Position count (3-position configuration)

The TE Connectivity Corcom Filters 6609015-3 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share identical connector geometry, current and voltage ratings, filtering specifications, and termination method. The substitute maintains active product status and current availability, providing a viable replacement for the obsolete Qualtek part.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Corcom Filters 6609015-3 is the qualified substitute for the obsolete Qualtek 857-03/017. Selection is based on the following engineering criteria:

Electrical equivalence is confirmed across all specified parameters: 3A current rating, 115/250VAC voltage support (120/250VAC on substitute exceeds minimum requirement), and identical EMI/RFI filtering at the appliance inlet. Mechanical compatibility is established through matching connector geometry, panel mount flange configuration, and quick connect termination specifications.

Regulatory compliance is maintained through ROHS3 certification on both parts. The substitute carries active product status with current manufacturing and inventory availability, eliminating supply chain risk associated with the obsolete Qualtek part. Approval agencies for the substitute (CSA, UL, VDE) provide established safety certifications suitable for commercial AC power applications.

The substitute's additional features (front or rear side mount capability, shielded design) provide enhanced flexibility without compromising compatibility with existing panel cutout dimensions or electrical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6609015-3 be used as a direct replacement in existing installations designed for the Qualtek 857-03/017?

A: Yes. Both parts share identical IEC 320-C14 connector geometry, 3A current rating, 115/250VAC voltage support, and quick connect termination. Panel cutout dimensions are compatible. No modifications to existing installations are required.

Q: What is the voltage rating difference between the two parts, and does it affect compatibility?

A: The Qualtek part is rated 115/250VAC, while the TE Connectivity substitute is rated 120/250VAC. The substitute's 120VAC minimum exceeds the original 115VAC specification, ensuring full compatibility with all applications designed for the original part.

Q: Are the filtering characteristics identical between the two parts?

A: Yes. Both parts feature commercial-grade EMI/RFI filtering at 3A current rating. Filtering performance and specifications are equivalent.

Q: Does the substitute's shielded design affect panel mount installation?

A: No. The shielded design is an enhancement that does not impact panel mount compatibility. Panel cutout dimensions remain compatible with existing installations.

Q: What is the packaging difference, and does it affect component selection?

A: The Qualtek part is supplied in standard packaging, while the TE Connectivity substitute is supplied in bulk packaging. This affects order quantities and logistics but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the Qualtek 857-03/017 and TE Connectivity 6609015-3 are ROHS3 compliant, meeting current environmental and material restriction requirements.
