Qualtek 723-20/48 AC Power Connector – Equivalent & Substitute Parts

Part Overview

The Qualtek 723-20/48 is an IEC 320-C14 power entry connector receptacle module designed for panel-mount applications with snap-in installation. This component features male blade termination, twin fused configuration, and accommodates 10A at 250VAC. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for direct substitution in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following electrical and mechanical parameters:

• Connector Style & Type: Must be IEC 320-C14 receptacle with male blades
• Electrical Ratings: Current and voltage ratings must match or exceed 10A at 250VAC
• Mounting Configuration: Panel mount with snap-in installation required
• Termination Method: Quick Connect 0.189" (4.8mm) terminals
• Fuse Accommodation: Must support fused configuration
• Panel Interface: Cutout dimensions and panel thickness compatibility

Both identified substitutes meet these criteria while offering improved product status and expanded certification coverage.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 723W-X2/03 is the primary substitute option within the same manufacturer family. It maintains identical electrical specifications and termination geometry while offering active product status and expanded panel thickness accommodation (0.031" to 0.079"). The variable cutout dimension capability provides design flexibility for retrofit applications. Certification coverage includes CSA, TUV, and UL.

SCHURTER 6200.4220 serves as a cross-manufacturer alternative with equivalent electrical performance and identical panel thickness specification. This option provides the broadest certification scope (CCC, CSA, ENEC, UL) and includes IP40 ingress protection. Panel cutout dimensions (27.50mm x 31.50mm) are nominally compatible with the original specification. The single fused configuration differs from the twin fused design of the main part; applications requiring dual fuse protection must confirm compatibility with system requirements.

Both substitutes are actively manufactured and ROHS3 compliant, ensuring long-term supply availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 723W-X2/03 directly replace the 723-20/48 in existing panel cutouts?

A: The 723W-X2/03 accommodates variable panel thickness (0.031" to 0.079"), which covers the original 0.079" specification. However, the variable cutout dimension feature requires verification that the panel opening dimensions are compatible with the snap-in mechanism. The original rectangular cutout of 27.30mm x 31.12mm falls within the variable size range.

Q: What is the functional difference between the twin fused 723-20/48 and the single fused 6200.4220?

A: The 723-20/48 incorporates a twin fused drawer configuration, while the 6200.4220 uses a single fuse holder. Both accommodate fuse protection; the difference lies in the number of independent fuse circuits. System design requirements determine whether dual or single fuse protection is necessary.

Q: Are panel cutout dimensions critical for substitution?

A: Panel cutout dimensions are critical for mechanical fit. The 723W-X2/03 offers variable size accommodation, while the 6200.4220 specifies 27.50mm x 31.50mm, which is nominally compatible with the original 27.30mm x 31.12mm. Verify that existing panel openings accommodate the substitute connector's snap-in mechanism.

Q: Do all three connectors meet the same electrical and safety standards?

A: All three connectors are rated 10A at 250VAC and are ROHS3 compliant. The 723-20/48 and 723W-X2/03 share CSA and UL certifications. The 6200.4220 adds CCC and ENEC certifications while maintaining CSA and UL approval, providing broader international compliance coverage.

Q: Is the Qualtek 723W-X2/03 preferred over the SCHURTER 6200.4220?

A: Selection depends on application requirements. The 723W-X2/03 maintains identical fuse configuration and remains within the original manufacturer family. The 6200.4220 offers expanded certification scope and ingress protection (IP40). Both are functionally equivalent for standard IEC 320-C14 panel-mount applications.
