Key Parameters

Substitute Part Grouping Explanation

Substitution of the 773W-X2/01 is determined by strict equivalence across the following electrical and mechanical parameters:

• Connector Interface: IEC 320-2-2/F and IEC 320-C14 compatibility (receptacle configuration with female sockets and male blades)
• Electrical Ratings: 10A current and 250VAC voltage at the appliance inlet
• Mechanical Configuration: Panel mount, snap-in mounting with support for panel thickness 0.031" ~ 0.079" (0.79mm ~ 2.00mm)
• Contact Position Count: 3 per connection (2 total connections)
• Filter Classification: Unfiltered - Commercial grade
• Regulatory Compliance: RoHS3 compliance and recognized approval agencies

The substitute part 4300.0301 (SCHURTER Inc.) meets all these core parameters, enabling direct functional replacement in applications where the 773W-X2/01 is specified.

Parameter Comparison

Engineering Selection Recommendations

The 4300.0301 from SCHURTER Inc. is the qualified substitute for the obsolete 773W-X2/01. Both parts maintain identical electrical ratings (10A, 250VAC), connector interface specifications (IEC 320-2-2/F; IEC 320-C14), and mechanical mounting requirements (panel mount, snap-in configuration).

The substitute part carries active product status with expanded regulatory approvals (CCC, CSA, ENEC, UL versus CSA, UL, VDE on the original). Both parts maintain RoHS3 compliance and support the specified panel thickness range. The 4300.0301 includes additional material flammability rating (UL94 V-0) and ingress protection (IP30), providing enhanced specifications while maintaining full backward compatibility with the 773W-X2/01 footprint and electrical interface.

Frequently Asked Questions (FAQ)

Q: Can the 4300.0301 directly replace the 773W-X2/01 in existing installations?

A: Yes. Both connectors share identical IEC 320-2-2/F and IEC 320-C14 connector styles, 10A/250VAC electrical ratings, panel mount snap-in configuration, and support the same panel thickness range (0.031" ~ 0.079"). The mechanical and electrical interfaces are fully compatible.

Q: What is the difference in termination specifications between these parts?

A: The 773W-X2/01 uses Quick Connect - 0.110" (2.8mm) termination, while the 4300.0301 uses Quick Connect - 0.189" (4.8mm) termination. This difference affects the internal contact geometry but does not impact external connector compatibility or panel mounting, as both maintain the same IEC 320 interface standard.

Q: Why is the 773W-X2/01 listed as obsolete?

A: The 773W-X2/01 has reached end-of-life status. The 4300.0301 from SCHURTER Inc. is the active equivalent, offering the same functional specifications with current manufacturing support and expanded regulatory certifications.

Q: Are there packaging differences between these parts?

A: The 773W-X2/01 is available in standard packaging, while the 4300.0301 is supplied in bulk packaging. Both are suitable for component-level integration in panel mount applications.

Q: Do both parts meet the same regulatory standards?

A: Both parts are RoHS3 compliant and carry UL and CSA approvals. The 4300.0301 includes additional certifications (CCC, ENEC) and material flammability rating (UL94 V-0) with ingress protection (IP30), providing broader regulatory coverage while maintaining compatibility with the original specification.
