Qualtek 857-06/027 AC Power Connector - Equivalent & Substitute Parts
Part Overview
The Qualtek 857-06/027 is a 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 6A 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.

Engineering Selection Recommendations
The TE Connectivity Corcom Filters 6609015-5 is the qualified equivalent for the obsolete Qualtek 857-06/027. Selection is based on:
Electrical Compatibility: Both parts maintain identical current ratings (6A) and equivalent voltage specifications (115/250VAC vs. 120/250VAC). The voltage differential of 5VAC on the upper range is within standard industrial tolerance and does not affect functional compatibility.
Mechanical Compatibility: Panel mount flange configuration, quick connect termination, and three-position design are identical. The TE Connectivity part supports front or rear side mount flexibility, providing installation advantages over the original design.
Regulatory Compliance: Both parts carry CSA, UL, and VDE certifications and maintain ROHS3 compliance. No regulatory gaps exist between the original and substitute.
Product Availability: The TE Connectivity part is active in production with 1524 units in stock, ensuring supply continuity for legacy system support and new installations.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 6609015-5 directly replace the Qualtek 857-06/027 in existing installations?
A: Yes. Both parts share identical IEC 320-C14 connector geometry, 6A current rating, EMI/RFI filtering, and panel mount flange configuration. The quick connect termination is compatible at 0.250" (6.3mm) standard.
Q: What is the voltage difference between 115/250VAC and 120/250VAC?
A: The 5VAC difference on the upper range falls within standard industrial operating margins. Both ratings support the same 250VAC maximum specification, ensuring functional equivalence in AC power entry applications.
Q: Does the TE Connectivity part require different panel cutout dimensions?
A: The TE Connectivity 6609015-5 specifies variable size panel cutout dimensions, which accommodates the original rectangular 30.48mm x 21.59mm opening. No panel modification is required.
Q: Are there any filtering differences between the two parts?
A: Both parts feature identical commercial-grade EMI/RFI filtering with 6A current rating. No filtering performance differential exists.
Q: What packaging format is available for the TE Connectivity substitute?
A: The TE Connectivity 6609015-5 is supplied in bulk packaging, suitable for production and service replacement applications.
Q: Are both parts RoHS compliant?
A: Yes. Both the Qualtek 857-06/027 and TE Connectivity 6609015-5 are ROHS3 compliant and REACH unaffected.
