Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 5123.1004.0.21 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (IEC 320-C14)
• Connector type (Receptacle, Male Blades - Module)
• Current rating (6A)
• Voltage rating (250VAC)
• Number of positions (3)
• Filter type (Filtered EMI/RFI - Commercial)

Mechanical Compatibility Parameters:

• Mounting type (Panel Mount, Flange)
• Termination method (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 29.00mm x 21.50mm)
• Panel thickness tolerance (0.315")

Regulatory & Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Ingress protection rating (IP40)
• Approval agencies (cURus, ENEC)
• RoHS compliance status (ROHS3 Compliant)

Parts meeting all parameters in these three categories are classified as direct substitutes.

Supply Chain Continuity:

The 5123.1004.0 is currently in active production with 824 units in stock, ensuring reliable procurement for new designs and replacement applications. The obsolete 5123.1004.0.21 remains available with 847 units in inventory for legacy support during transition periods.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 5123.1004.0 directly replace the 5123.1004.0.21 in existing designs?

A: Yes. The 5123.1004.0 is a direct substitute with identical electrical ratings (6A, 250VAC), mechanical dimensions (29.00mm x 21.50mm panel cutout), connector style (IEC 320-C14), and regulatory certifications (cURus, ENEC, UL94 V-0, ROHS3). No design modifications are required.

Q: What is the difference between part numbers 5123.1004.0.21 and 5123.1004.0?

A: The primary difference is product status. The 5123.1004.0.21 is classified as obsolete, while the 5123.1004.0 is active. All functional, electrical, and mechanical parameters are identical. The suffix ".21" in the obsolete part number does not indicate a functional variant.

Q: Are the panel cutout dimensions identical between both parts?

A: Yes. Both parts require a rectangular panel cutout of 29.00mm x 21.50mm and accommodate panel thickness of 0.315" (8.00mm). No panel modifications are necessary when substituting between these parts.

Q: Do both parts use the same termination method?

A: Yes. Both the 5123.1004.0.21 and 5123.1004.0 use Quick Connect termination with 0.250" (6.3mm) blade spacing. Wiring harnesses and internal connections are compatible.

Q: What is the current availability status of each part?

A: The active substitute 5123.1004.0 has 824 units in stock. The obsolete 5123.1004.0.21 has 847 units available for legacy applications. New procurement should specify the active part number 5123.1004.0.

Q: Are the EMI/RFI filter specifications identical?

A: Yes. Both parts feature commercial-grade filtered (EMI, RFI) design with a 6A current rating. Filter performance and specifications are equivalent.

Q: Do both parts meet the same regulatory certifications?

A: Yes. Both parts carry cURus and ENEC approvals, UL94 V-0 flammability rating, and ROHS3 compliance. Regulatory requirements for both parts are identical.
