Key Parameters

Substitute Part Grouping Explanation

Substitution for the Qualtek 703-00/28 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Style: IEC 320-C14 (male blades configuration)
• Connector Type: Receptacle, Male Blades
• Number of Positions: 3
• Mounting Type: Panel Mount, Flange
• Filter Type: Unfiltered - Commercial

Secondary Compatibility Criteria:

• Electrical ratings: 10A / 250VAC (where specified)
• Material Flammability: UL94 V-0
• Regulatory compliance: CSA, UL, or equivalent international certifications
• RoHS3 compliance

The substitute parts are grouped into two categories:

Group 1 - Direct IEC 320-C14 Male Blades Equivalents:

• Qualtek 703W-00/07: Active status alternative with identical connector style and male blades configuration, featuring quick connect termination (0.189" / 4.8mm)
• SCHURTER 6100.3100: Active status alternative with solder eyelet termination and enhanced ingress protection (IP40)

Group 2 - IEC 320-2-2/F Female Sockets Alternatives:

• SCHURTER 6182.0002, 6182.0006, 6182.0007, 6182.0008: These parts feature female sockets configuration (IEC 320-2-2/F) rather than male blades, representing a different connector interface type but maintaining the same panel mount flange design and unfiltered commercial specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (IEC 320-C14 Male Blades):

The Qualtek 703W-00/07 is the manufacturer-recommended equivalent, maintaining the same connector style and male blades configuration. This part is in active production status with significantly higher inventory availability (18,028 pcs vs. 678 pcs for the obsolete 703-00/28). The primary difference is termination pin size (0.189" vs. 0.110"), which requires verification against PCB or terminal block specifications. Regulatory compliance includes CSA, UL, and VDE certifications, exceeding the original part's approval scope.

The SCHURTER 6100.3100 provides an alternative IEC 320-C14 male blades solution with solder eyelet termination, suitable for applications requiring direct PCB soldering. This part includes enhanced ingress protection (IP40) and broader regulatory certifications (CCC, cULus, ENEC), making it suitable for international applications. Inventory availability is adequate (4,616 pcs).

For Alternative Interface (IEC 320-2-2/F Female Sockets):

The SCHURTER 6182 series (parts 6182.0002, 6182.0006, 6182.0007, 6182.0008) represents a different connector interface type with female sockets rather than male blades. These parts maintain panel mount flange design and unfiltered commercial specification but require compatible mating connectors. Selection within this series depends on termination preference: solder eyelet (6182.0002) or quick connect 0.250" (6182.0006, 6182.0007, 6182.0008). All parts carry identical electrical ratings (10A / 250VAC) and regulatory approvals (cCSAus, UL, VDE).

Frequently Asked Questions (FAQ)

Q: Can the Qualtek 703W-00/07 be used as a direct drop-in replacement for the 703-00/28?

A: The 703W-00/07 maintains identical connector style (IEC 320-C14), connector type (receptacle, male blades), and mounting configuration (panel mount, flange). However, the termination pin size differs (0.189" vs. 0.110"), requiring verification that the receiving terminal block or PCB accommodates the larger pin diameter. If the original application uses 0.110" quick connect terminals, a terminal block adapter or redesign may be necessary.

Q: What is the difference between the Qualtek 703W-00/07 and SCHURTER 6100.3100?

A: Both maintain IEC 320-C14 male blades configuration and panel mount flange design. The primary differences are: (1) termination method—703W-00/07 uses quick connect 0.189", while 6100.3100 uses solder eyelet; (2) ingress protection—6100.3100 provides IP40 rating versus unspecified for 703W-00/07; (3) regulatory scope—6100.3100 includes CCC and ENEC certifications in addition to cULus. Selection depends on assembly method (quick connect vs. soldering) and environmental protection requirements.

Q: Why are the SCHURTER 6182 series parts listed as substitutes if they use female sockets instead of male blades?

A: The 6182 series parts are listed based on the original part's substitute list provided in the input data. These parts share the same panel mount flange design, unfiltered commercial specification, and electrical ratings (10A / 250VAC). However, they represent a different connector interface (IEC 320-2-2/F female sockets vs. IEC 320-C14 male blades). Substitution is only valid if the application can accommodate a female socket interface with compatible mating connectors.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (703W-00/07, 6100.3100, and the 6182 series) are ROHS3 compliant, matching the compliance status of the original 703-00/28.

Q: What inventory considerations should guide part selection?

A: The Qualtek 703W-00/07 offers the highest inventory availability (18,028 pcs), providing supply security for high-volume applications. The SCHURTER 6100.3100 maintains adequate stock (4,616 pcs). The 6182 series parts have lower individual inventory levels (949–1,290 pcs), which may impact availability for large-scale production requirements.

Q: Which substitute part has the broadest international regulatory approval?

A: The SCHURTER 6100.3100 carries the most comprehensive regulatory certifications (CCC, cULus, ENEC), making it suitable for applications requiring compliance across North American, European, and Chinese markets. The 6182 series parts include cCSAus, UL, and VDE certifications, covering North American and European requirements.
