Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 761-18/001 is determined by the following critical parameters:

• Connector Style Match: IEC 320-C14 standard compliance
• Connector Type: Receptacle configuration with male blades in module format
• Position Count: 3-position connector
• Filter Classification: Unfiltered commercial-grade design
• Mounting Category: Panel mount configuration
• Regulatory Compliance: CSA and UL certifications

The SCHURTER Inc. DC21.0023.1111 qualifies as an equivalent substitute based on matching connector style, type, position count, filter classification, and regulatory approvals. Differences in mounting subtype (snap-in versus flange/through-hole), termination method (solder eyelet versus solder), and additional features (fuse holder versus switch functionality) represent design variations within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Both the Qualtek 761-18/001 and SCHURTER DC21.0023.1111 maintain active product status and ROHS3 compliance. The Qualtek connector is certified by CSA and UL, while the SCHURTER connector carries cULus and ENEC certifications. Selection between these parts depends on specific application requirements:

• Qualtek 761-18/001: Select when snap-in panel mounting and integrated fuse holder accommodation are required design specifications.
• SCHURTER DC21.0023.1111: Select when flange-based through-hole mounting, right-angle termination, and on-off illuminated switch functionality are application requirements.

Both connectors satisfy IEC 320-C14 receptacle specifications for unfiltered commercial power entry applications with 3-position configuration.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER DC21.0023.1111 directly replace the Qualtek 761-18/001 in existing designs?

A: Direct replacement requires verification of mounting type compatibility. The Qualtek uses snap-in mounting while the SCHURTER uses flange-based through-hole mounting. Panel cutout dimensions and thickness tolerances must be evaluated for your specific application.

Q: What is the significance of the fuse accommodation difference?

A: The Qualtek 761-18/001 includes a fuse holder drawer for integrated fuse protection. The SCHURTER DC21.0023.1111 does not accommodate a fuse. If fuse protection is a circuit requirement, external fusing must be implemented with the SCHURTER connector.

Q: Are the termination methods interchangeable?

A: Both connectors use solder termination but differ in configuration. The Qualtek uses solder eyelet termination while the SCHURTER uses standard solder termination. PCB layout and trace routing may require adjustment based on the selected connector.

Q: Do both connectors meet the same regulatory standards?

A: Both connectors are ROHS3 compliant. The Qualtek carries CSA and UL approvals; the SCHURTER carries cULus and ENEC approvals. Verify that your application's regulatory requirements align with the certification body requirements of your selected connector.

Q: What panel thickness range does each connector support?

A: The Qualtek 761-18/001 supports panel thickness of 0.040" to 0.070" (1.02mm to 1.78mm). The SCHURTER DC21.0023.1111 supports 0.138" (3.50mm) panel thickness. Panel thickness compatibility is a critical selection criterion.
