Qualtek 744W-00/02 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Qualtek 744W-00/02 is an IEC 320-C20 power entry connector receptacle designed for panel-mount applications in commercial AC power distribution systems. This component features male blades, quick-connect termination, and is rated for 16A at 250VAC across three positions. The 744W-00/02 is classified as obsolete, necessitating identification of active equivalent parts to maintain supply chain continuity for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The Qualtek 744W-00/04 qualifies as a direct substitute for the 744W-00/02 based on the following critical parameters:

• Connector Style & Type: Both parts maintain IEC 320-C20 receptacle configuration with male blades
• Electrical Ratings: Identical current (16A) and voltage (250VAC) specifications
• Mechanical Interface: Matching panel mount flange design with identical cutout dimensions (32.00mm x 24.00mm)
• Position Count: Both feature three-position configuration
• Regulatory Compliance: Both hold CSA, UL, and VDE approvals; both are ROHS3 compliant

The primary difference between these parts is the termination connector size: the 744W-00/02 uses 0.157" (3.9mm) quick-connect terminals, while the 744W-00/04 uses 0.250" (6.3mm) quick-connect terminals. This distinction requires verification of mating connector specifications in the target application.

Parameter Comparison

Engineering Selection Recommendations

The 744W-00/04 is the manufacturer-recommended substitute for the obsolete 744W-00/02. Both parts maintain identical electrical and mechanical specifications for panel mounting, cutout dimensions, and regulatory certifications. The 744W-00/04 is currently in active production with significantly higher inventory availability (3280 pcs vs. 1021 pcs).

Selection of the 744W-00/04 requires confirmation that the mating connector harness or internal wiring accommodates the 0.250" (6.3mm) quick-connect terminal size, as this differs from the original 0.157" (3.9mm) specification. If the existing termination infrastructure is fixed to the smaller terminal size, alternative sourcing strategies must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the 744W-00/04 directly replace the 744W-00/02 in existing applications?

A: The 744W-00/04 provides electrical and mechanical compatibility for panel mounting and cutout dimensions. However, the termination connector size differs (0.250" vs. 0.157"), requiring verification that mating connectors or internal wiring can accommodate the larger terminal specification.

Q: What is the significance of the different quick-connect terminal sizes?

A: The termination size determines compatibility with mating connector pins and internal wiring harnesses. The 744W-00/04 uses larger 0.250" terminals, which may require different mating connectors than those designed for the 0.157" terminals of the 744W-00/02.

Q: Are both parts certified to the same standards?

A: Yes. Both the 744W-00/02 and 744W-00/04 hold identical approvals from CSA, UL, and VDE, and both are ROHS3 compliant.

Q: Why is the 744W-00/02 listed as obsolete?

A: The 744W-00/02 has been discontinued by the manufacturer. The 744W-00/04 represents the active production equivalent within the 744W series.

Q: What packaging is available for the 744W-00/04?

A: The 744W-00/04 is supplied in bulk packaging, with 3280 units currently in stock.
