Qualtek 716-20/28 AC Power Connector: Equivalent & Substitute Parts

Part Overview

The Qualtek 716-20/28 is an IEC 320-2-2/F power entry connector receptacle designed for panel-mount applications with snap-in installation. This component features female sockets for AC power inlet connections in commercial equipment. The part is currently obsolete, making equivalent substitutes necessary for new designs, repairs, and system upgrades. Substitute parts must maintain electrical compatibility, mechanical fit, and regulatory compliance with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 716-20/28 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Connector style must be IEC 320-2-2/F
• Connector type must be receptacle with female sockets
• Number of positions must be 3
• Mounting type must be panel mount, snap-in
• Filter type must be unfiltered - commercial
• Panel cutout dimensions must accommodate the original 32.26mm x 24.77mm rectangular opening
• Panel thickness compatibility must be verified against the substitute's supported range
• Termination must be quick connect type
• RoHS3 compliance required

Electrical Parameters (where specified):

• Current rating and voltage rating must meet or exceed application requirements
• Approval agencies should include CSA and/or UL certification

The two substitute parts listed below meet these criteria with variations in termination pin size, panel thickness tolerance, and approval agency coverage.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 716W-X2/02 is the manufacturer-recommended direct substitute. It maintains Qualtek series continuity with active product status and expanded approval agency coverage (CSA, TUV, UL). The primary design difference is the termination pin size (0.189" vs. 0.110"), which requires verification against mating connector specifications. Panel thickness tolerance is narrower (0.031" ~ 0.059") compared to the original, necessitating confirmation of panel thickness in the target application.

Switchcraft EAC405040 and EAC405060 provide alternative sourcing from an established connector manufacturer. Both maintain IEC 320-2-2/F compatibility and 10A/250VAC electrical ratings. The EAC series uses 0.187" termination pins, similar to the Qualtek 716W-X2/02. Selection between EAC405040 and EAC405060 depends on panel thickness: EAC405040 accommodates 0.036" ~ 0.050" panels, while EAC405060 accommodates 0.056" ~ 0.070" panels. Approval agency information is not specified for Switchcraft parts.

All substitute parts are ROHS3 compliant and maintain the unfiltered commercial filter type of the original.

Frequently Asked Questions (FAQ)

Q: Can the 716W-X2/02 directly replace the 716-20/28 without modifications?

A: The 716W-X2/02 maintains electrical and mechanical compatibility as an IEC 320-2-2/F receptacle. However, the termination pin diameter differs (0.189" vs. 0.110"), requiring verification that mating connectors accept the larger pin size. Panel thickness tolerance is also narrower, so confirm the target panel thickness falls within 0.031" ~ 0.059".

Q: What is the difference between the Switchcraft EAC405040 and EAC405060?

A: Both parts are electrically and mechanically identical IEC 320-2-2/F receptacles with 0.187" termination pins. The sole difference is panel thickness tolerance: EAC405040 supports 0.036" ~ 0.050" panels, while EAC405060 supports 0.056" ~ 0.070" panels. Select based on your application's panel thickness.

Q: Are the panel cutout dimensions identical across all parts?

A: Panel cutout dimensions vary slightly. The original 716-20/28 specifies 32.26mm x 24.77mm. The 716W-X2/02 requires 32.60mm x 25.30mm (slightly larger), while both Switchcraft parts require 32.26mm x 24.76mm (essentially identical to the original). Verify existing panel cutouts before selecting a substitute.

Q: Do all substitute parts have the same approval certifications?

A: No. The 716W-X2/02 carries CSA, TUV, and UL approvals. The Switchcraft EAC405040 and EAC405060 do not specify approval agencies in the provided data. If specific certifications are required for your application, the 716W-X2/02 is the preferred choice.

Q: What does the termination pin size difference mean for my application?

A: The termination pin diameter determines compatibility with mating connectors. The original 716-20/28 uses 0.110" (2.8mm) pins. Substitutes use 0.187" (4.7mm) or 0.189" (4.8mm) pins. Your mating connector must accept the substitute's pin size. Verify pin socket specifications before proceeding with substitution.

Q: Are all parts RoHS3 compliant?

A: Yes. The 716-20/28 and all listed substitutes are ROHS3 compliant, meeting environmental and hazardous substance restrictions.
