Key Parameters

Substitute Part Grouping Explanation

Substitution of the Qualtek 703-00/07/C is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: IEC 320-C14 receptacle with male blades (fixed requirement)
• Mounting Configuration: Panel mount with flange and right-angle through-hole termination (fixed requirement)
• Termination Method: Solder termination (fixed requirement)
• Number of Positions: 3-position configuration (fixed requirement)
• Filter Classification: Unfiltered - Commercial (fixed requirement)
• Regulatory Compliance: CSA and UL approval (minimum requirement)

The identified substitute parts, Qualtek 703W-00/53 and Qualtek 703W-00/54, maintain full equivalence across all critical parameters while offering the additional advantage of active product status and expanded regulatory approvals (VDE certification included).

Parameter Comparison

Engineering Selection Recommendations

Both Qualtek 703W-00/53 and Qualtek 703W-00/54 are functionally equivalent substitutes for the obsolete 703-00/07/C. Selection between these two active alternatives should be based on panel cutout dimensions specific to your application:

• 703W-00/53: Panel cutout 31.30mm x 23.30mm; panel thickness 0.118" (3.00mm)
• 703W-00/54: Panel cutout 31.10mm x 23.30mm; panel thickness 0.118" (3.00mm)

Both parts maintain ROHS3 compliance and carry expanded regulatory approvals (CSA, UL, VDE), providing enhanced market acceptance and regulatory coverage compared to the original part. Active product status ensures long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can 703W-00/53 and 703W-00/54 be used interchangeably with 703-00/07/C?

A: Yes, both substitute parts maintain full functional equivalence across all critical parameters: IEC 320-C14 connector style, 3-position receptacle configuration, panel mount flange with right-angle through-hole solder termination, and unfiltered commercial filter classification. Panel cutout dimensions differ slightly between substitutes and the original part; verify panel hole dimensions before installation.

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

A: Both parts are functionally identical. The primary difference is panel cutout width: 703W-00/53 specifies 31.30mm width, while 703W-00/54 specifies 31.10mm width. Both maintain 23.30mm height and 0.118" (3.00mm) panel thickness. Select based on your panel hole dimensions.

Q: Why is the original 703-00/07/C classified as obsolete?

A: The 703-00/07/C is no longer in active production. The 703W series represents the current active product line for this connector category, offering improved availability and expanded regulatory certifications.

Q: Are there packaging differences between these parts?

A: The original 703-00/07/C packaging is not specified in available documentation. Both substitute parts are supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do the substitute parts carry the same regulatory approvals?

A: The substitute parts carry expanded approvals: CSA, UL, and VDE certification, compared to CSA and UL for the original part. This provides broader regulatory coverage for international applications.
