Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 703-00/07 is determined by the following critical parameters:

• Connector Style & Type: IEC 320-C14 receptacle with male blades
• Mounting Configuration: Panel mount with flange, through hole, right angle orientation
• Termination Method: Solder connection
• Electrical Specifications: 3-position connector for unfiltered commercial applications
• Mechanical Compatibility: Panel cutout dimensions and thickness tolerance
• Regulatory Compliance: CSA and UL approval minimum requirement

Two substitute parts meet these criteria with varying degrees of mechanical and electrical alignment.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 703W-00/53 is the primary substitute for the 703-00/07. Both components are manufactured by Qualtek, share identical connector style (IEC 320-C14 with male blades), mounting configuration, and termination method. The 703W-00/53 is active in production with expanded regulatory approvals (CSA, UL, VDE) and specified electrical ratings (10A, 250VAC). Panel cutout dimensions differ slightly (31.30mm x 23.30mm versus 30.25mm x 22.48mm), requiring panel redesign consideration. This part is the manufacturer-recommended replacement.

SCHURTER 6182.0033 serves as an alternative substitute with the same mounting and termination characteristics. However, this part uses IEC 320-2-2/F connector style with female sockets, representing a different connector interface than the original male blades configuration. Panel cutout dimensions are larger (34.40mm x 25.90mm), requiring significant panel modification. This substitute is suitable only when connector interface compatibility can be accommodated in the application design. SCHURTER provides additional ingress protection (IP20) and material flammability rating (UL94 V-0) not specified in the original part.

Both substitutes maintain ROHS3 compliance and unfiltered commercial filter type classification.

Frequently Asked Questions (FAQ)

Q: Can the 703W-00/53 be used as a direct drop-in replacement for the 703-00/07?

A: The 703W-00/53 shares the same connector style, type, mounting configuration, and termination method. However, panel cutout dimensions differ (31.30mm x 23.30mm versus 30.25mm x 22.48mm), requiring panel modification. Electrical specifications are now defined (10A, 250VAC) in the substitute part.

Q: What is the primary difference between the Qualtek and SCHURTER substitutes?

A: The Qualtek 703W-00/53 maintains the IEC 320-C14 male blades connector interface. The SCHURTER 6182.0033 uses IEC 320-2-2/F female sockets, requiring different mating connector geometry. Panel cutout dimensions also differ significantly between the two options.

Q: Are both substitutes regulatory compliant?

A: Both substitutes are ROHS3 compliant and hold CSA/UL approvals meeting the original part's minimum regulatory requirements. The 703W-00/53 adds VDE approval; the 6182.0033 includes CCC, cCSAus, and ENEC certifications.

Q: What panel modifications are required for each substitute?

A: The 703W-00/53 requires panel cutout adjustment from 30.25mm x 22.48mm to 31.30mm x 23.30mm. The 6182.0033 requires larger panel cutout modification to 34.40mm x 25.90mm. Panel thickness tolerance differs slightly between parts.

Q: Is the 703W-00/53 the manufacturer-recommended substitute?

A: Yes, the 703W-00/53 is identified as the manufacturer-recommended replacement for the obsolete 703-00/07, maintaining the same Qualtek product line and connector interface.
