Qualtek 718-20/28 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Qualtek 718-20/28 is an IEC 320-2-2/H panel mount power entry connector receptacle with female sockets and quick connect termination. This component is classified as obsolete, necessitating identification of active equivalent models to maintain supply chain continuity for applications requiring IEC 320-2-2 series power entry connectors.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 718-20/28 are identified based on the following critical parameters that determine functional compatibility:

• Connector Style & Type: IEC 320-2-2 series receptacle with female sockets
• Mounting Configuration: Panel mount, snap-in installation
• Termination Method: Quick connect terminals
• Filter Classification: Unfiltered commercial grade
• Regulatory Compliance: RoHS3 compliance and recognized approval agencies

The substitute parts listed below maintain these core functional parameters while representing active product status alternatives. Note that connector style variants (IEC 320-2-2/F vs. IEC 320-2-2/H) and position count differences are documented in the parameter comparison table.

Engineering Selection Recommendations

716W-X2/02 (Qualtek) is the manufacturer-recommended substitute, maintaining Qualtek brand continuity with active product status. This part carries expanded regulatory approvals (CSA, TUV, UL) compared to the original 718-20/28. The 716W-X2/02 is available in high inventory (12,359 pcs) and is packaged in bulk format.

6600.4215 (SCHURTER Inc.) provides an alternative from an established connector manufacturer with active product status. This part includes additional features (light pipe) and enhanced ingress protection (IP30) with material flammability rating (UL94 V-0). Regulatory approvals include CCC, cULus, and ENEC certifications. Inventory availability is 1,154 pcs.

Both substitute parts differ from the original in connector style variant (IEC 320-2-2/F vs. /H), position count (3 vs. 2), and termination pin size (0.189" vs. 0.110"). Panel cutout dimensions are similar but not identical. Panel thickness tolerance ranges differ significantly.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 718-20/28 and its substitutes?

A: The main part is obsolete with IEC 320-2-2/H connector style and 2 positions. Both substitutes are active products with IEC 320-2-2/F connector style and 3 positions. The connector style variant and position count represent design differences that must be evaluated for application compatibility.

Q: Can the 716W-X2/02 be used as a direct replacement?

A: The 716W-X2/02 maintains the same mounting method (panel mount, snap-in), termination type (quick connect), and filter classification (unfiltered commercial). However, the connector style variant, position count, and termination pin size differ. Panel cutout dimensions are similar but require verification for existing panel designs.

Q: What are the key differences between the two substitute options?

A: The 716W-X2/02 is a Qualtek product with CSA, TUV, and UL approvals. The 6600.4215 is a SCHURTER product with CCC, cULus, and ENEC approvals, includes a light pipe feature, and provides IP30 ingress protection with UL94 V-0 material flammability rating. Both carry identical electrical ratings (10A, 250VAC) and use 0.189" quick connect termination.

Q: Are panel cutout dimensions compatible with existing designs?

A: Panel cutout dimensions are similar but not identical across all three parts. The 718-20/28 requires 32.26mm x 24.77mm; the 716W-X2/02 requires 32.60mm x 25.30mm; the 6600.4215 requires 32.50mm x 24.80mm. Panel thickness tolerance ranges also differ. Existing panel designs must be evaluated for accommodation of these dimensional variations.

Q: What is the significance of the termination pin size difference?

A: The original 718-20/28 uses 0.110" (2.8mm) quick connect terminals, while both substitutes use 0.189" (4.8mm) terminals. This difference requires compatible mating connectors and wiring harness redesign if substituting into existing applications.

Q: Which substitute has better regulatory coverage?

A: The 6600.4215 provides the broadest regulatory approvals (CCC, cULus, ENEC) and includes material flammability certification (UL94 V-0) and ingress protection rating (IP30). The 716W-X2/02 carries CSA, TUV, and UL approvals. Selection depends on specific application regulatory requirements.
