Qualtek 703-00/09 AC Power Connector: Equivalent & Substitute Parts

Part Overview

The Qualtek 703-00/09 is an IEC 320-C14 power entry connector receptacle designed for panel-mount applications with through-hole, right-angle termination. This component functions as a male-blade receptacle for AC power inlet connections in commercial equipment. The 703-00/09 is classified as obsolete, necessitating identification of active equivalent models to ensure continued component availability and design continuity for maintenance and new production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 703-00/09 is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: Both substitute parts maintain IEC 320-C14 receptacle, male-blade configuration
• Mounting Configuration: Panel mount with flange and through-hole, right-angle termination preserved
• Electrical Specifications: Current rating (10A) and voltage rating (250VAC) meet or exceed the original specification
• Position Count: 3-position configuration maintained
• Termination Method: Solder termination consistent across all parts
• Regulatory Compliance: CSA and UL approvals present in all substitute parts; VDE certification added in active models
• Environmental Compliance: ROHS3 compliance and REACH unaffected status maintained

The substitute parts 703W-00/53 and 703W-00/54 are both active products within the 703W series, providing direct functional equivalence with enhanced availability and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Both 703W-00/53 and 703W-00/54 are qualified substitutes for the obsolete 703-00/09 based on functional equivalence and regulatory compliance. Selection between the two active alternatives should be based on panel cutout dimensional requirements:

• 703W-00/53: Panel cutout 31.30mm x 23.30mm; suitable for applications where panel opening dimensions accommodate this specification
• 703W-00/54: Panel cutout 31.10mm x 23.30mm; suitable for applications with slightly tighter horizontal dimensional constraints

Both parts maintain CSA, UL, and VDE certifications, ensuring compliance with international safety standards. The transition from the obsolete 703-00/09 to either active 703W series part provides enhanced supply chain stability and manufacturing support. Panel thickness tolerance differences (0.126" vs. 0.118") must be evaluated against specific installation requirements.

Frequently Asked Questions (FAQ)

Q: Can 703W-00/53 and 703W-00/54 be used interchangeably with 703-00/09?

A: Both 703W series parts provide functional equivalence as IEC 320-C14 receptacles with identical connector type, mounting configuration, and termination method. Panel cutout dimensions differ slightly between models and the original part; panel thickness tolerance must be verified for the specific installation.

Q: What is the primary difference between 703W-00/53 and 703W-00/54?

A: The primary difference is panel cutout width: 703W-00/53 specifies 31.30mm x 23.30mm, while 703W-00/54 specifies 31.10mm x 23.30mm. Both maintain identical electrical ratings (10A, 250VAC) and mounting characteristics.

Q: Are the substitute parts RoHS compliant?

A: Yes, both 703W-00/53 and 703W-00/54 are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the original 703-00/09.

Q: What certifications do the substitute parts carry?

A: Both substitute parts carry CSA, UL, and VDE approvals, providing broader international regulatory coverage compared to the original part (CSA, UL only).

Q: How do panel thickness specifications affect substitution?

A: The original 703-00/09 accommodates panel thickness of 0.126" (3.20mm), while both substitute parts accommodate 0.118" (3.00mm). Panel thickness tolerance must be evaluated for the specific installation to ensure proper flange seating and mechanical integrity.
