Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 5123.1303.0.21 is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Connector style must be IEC 320-C14
• Voltage rating must be 250VAC
• Filter type must be Filtered (EMI, RFI) - Commercial, Medical
• Number of positions must be 3

Mechanical Compatibility:

• Mounting type must be Panel Mount, Flange
• Termination must be Quick Connect - 0.250" (6.3mm)
• Panel thickness accommodation must be 0.315" (8.00mm)

Regulatory & Compliance:

• Material flammability rating must be UL94 V-0
• Ingress protection must be IP40
• Approval agencies must include cURus and ENEC
• RoHS3 compliance required

The substitute part SCHURTER 5123.1303.0 meets all critical substitution criteria. The primary difference is an increased appliance inlet current rating (10A versus 4A on the original), which represents an upward-compatible enhancement. The substitute also features an Active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 5123.1303.0 is the direct substitute for the obsolete 5123.1303.0.21. Both components share identical IEC 320-C14 connector specifications, filtering characteristics, mounting configurations, and regulatory certifications (cURus/cULus and ENEC).

The substitute part carries Active product status, ensuring continued manufacturing support, supply chain availability, and technical documentation access. Both components maintain UL94 V-0 flammability compliance and ROHS3 certification, meeting current regulatory requirements.

The increased appliance inlet current rating of the substitute (10A versus 4A) provides enhanced electrical capacity while maintaining compatibility with the original 4A filter rating and all mechanical interfaces. This upward-compatible rating does not introduce incompatibility with existing designs.

Panel cutout dimensions differ slightly (30.50mm x 22.50mm for the substitute versus 29.00mm x 21.50mm for the original). Panel modification may be required for direct mechanical substitution in existing enclosures.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 5123.1303.0 directly replace the 5123.1303.0.21 in existing equipment?

A: Electrical and functional compatibility is confirmed. The substitute meets all IEC 320-C14 specifications, filtering requirements, and regulatory certifications. Panel cutout dimensions differ slightly, requiring verification of mechanical fit in existing enclosure designs.

Q: What is the significance of the increased 10A current rating on the substitute part?

A: The substitute provides higher appliance inlet current capacity (10A versus 4A). This represents an upward-compatible enhancement. The filter current rating remains 4A on both components, maintaining the original filtering performance.

Q: Are both components suitable for medical applications?

A: Both the original and substitute components are specified with Filtered (EMI, RFI) - Commercial, Medical filter type, confirming suitability for medical device applications.

Q: What are the key differences between the two parts?

A: Primary differences are product status (Obsolete versus Active), appliance inlet current rating (4A versus 10A), panel cutout dimensions (29.00mm x 21.50mm versus 30.50mm x 22.50mm), and approval agency designation (cURus versus cULus). All electrical, filtering, and regulatory compliance parameters remain equivalent.

Q: Is the substitute part available in the same packaging as the original?

A: The original part number 5123.1303.0.21 was supplied in standard packaging. The substitute 5123.1303.0 is available in Bulk packaging, with 835 pieces currently in stock.

Q: Do both components meet current RoHS and regulatory requirements?

A: Both components are ROHS3 compliant and carry approvals from cURus/cULus and ENEC, meeting current regulatory standards for AC power connectors in commercial and medical applications.
