Qualtek 723-20/28 AC Power Connector – Equivalent & Substitute Parts

Part Overview

The Qualtek 723-20/28 is an IEC 320-C14 power entry connector receptacle module designed for panel-mount, snap-in installation in AC power distribution applications. This component features male blade termination, twin fused configuration, and accommodates 10A at 250VAC. The part is currently obsolete, making identification of functionally equivalent substitutes essential for maintenance, repair, and legacy system support. Substitute parts must maintain identical electrical ratings, connector geometry, and mechanical mounting specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Qualtek 723-20/28 are qualified based on strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current rating (10A) and voltage rating (250VAC)
• Connector Interface: IEC 320-C14 standard with receptacle, male blades configuration
• Mechanical Mounting: Panel mount, snap-in installation method
• Fuse Accommodation: Twin fused configuration with fuse holder drawer
• Termination Method: Quick Connect or equivalent termination suitable for 0.110" (2.8mm) blade spacing
• Regulatory Compliance: ROHS3 compliance and recognized approval agencies (CSA, UL, VDE, or equivalent)

Two substitute parts meet these criteria: Qualtek 723W-X2/02 and SCHURTER 6200.4120. Both maintain full electrical and mechanical compatibility with the original part while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 723W-X2/02 is the manufacturer-recommended substitute, offering direct compatibility with the original 723-20/28. This part maintains active product status, identical electrical specifications, and equivalent mechanical mounting. The 723W series represents the current-generation evolution of the 723 series. Panel thickness accommodation ranges from 0.031" to 0.079" (0.79mm to 2.00mm), providing flexibility for various panel configurations. Quick Connect termination at 0.110" (2.8mm) ensures compatibility with existing harness assemblies.

SCHURTER 6200.4120 provides an alternative from an independent manufacturer with broader regulatory approval (CCC, ENEC in addition to CSA and UL). This part features solder eyelet termination instead of quick connect, requiring harness modification or adapter consideration. Panel cutout dimensions are slightly larger (27.50mm x 31.50mm versus 27.30mm x 31.12mm), and ingress protection rating of IP40 provides enhanced environmental sealing. Material flammability rating matches the original specification (UL94 V-0).

Selection between these substitutes depends on termination method requirements and panel modification tolerance. For direct replacement without harness rework, Qualtek 723W-X2/02 is the preferred choice. For applications requiring enhanced environmental protection and independent manufacturer sourcing, SCHURTER 6200.4120 is suitable with termination adaptation.

Frequently Asked Questions (FAQ)

Q: Can the Qualtek 723W-X2/02 be used as a direct drop-in replacement for the 723-20/28?

A: Yes. Both parts share identical IEC 320-C14 connector geometry, 10A/250VAC electrical ratings, panel mount snap-in installation, and quick connect termination at 0.110" (2.8mm). The 723W-X2/02 accommodates panel thicknesses from 0.031" to 0.079", covering the original specification of 0.079" (2.00mm).

Q: What is the primary difference between the Qualtek and SCHURTER substitutes?

A: Termination method differs. Qualtek 723W-X2/02 uses quick connect termination compatible with existing 0.110" (2.8mm) blade harnesses. SCHURTER 6200.4120 uses solder eyelet termination, requiring harness modification or adapter implementation. Both maintain identical electrical ratings and IEC 320-C14 compliance.

Q: Are panel cutout dimensions interchangeable between all three parts?

A: The Qualtek 723-20/28 and 723W-X2/02 specify rectangular cutouts of 27.30mm x 31.12mm. SCHURTER 6200.4120 specifies 27.50mm x 31.50mm. Existing panel cutouts for the original part will accommodate the Qualtek substitute without modification. SCHURTER installation may require minor panel enlargement depending on existing cutout tolerance.

Q: Do all three parts accommodate fuses?

A: Yes. Qualtek 723-20/28 and 723W-X2/02 feature twin fused configuration with fuse holder drawer. SCHURTER 6200.4120 includes a fuse holder. All three parts accommodate fuses but do not include fuses in the package.

Q: What regulatory approvals apply to each part?

A: Qualtek 723-20/28 carries CSA, UL, and VDE approval. Qualtek 723W-X2/02 carries CSA, TUV, and UL approval. SCHURTER 6200.4120 carries CCC, CSA, ENEC, and UL approval. All three meet ROHS3 compliance and REACH unaffected status.

Q: Is the Qualtek 723W-X2/02 available in higher quantities than the original part?

A: Yes. Inventory data indicates 2,837 pieces of 723W-X2/02 in stock compared to 855 pieces of the obsolete 723-20/28, providing superior supply chain reliability for ongoing production and maintenance requirements.
