Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 718-10/28 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector type: Receptacle with female sockets
• Mounting configuration: Panel mount, snap-in installation
• Filter classification: Unfiltered - Commercial
• Regulatory compliance: CSA and/or UL approval
• RoHS compliance: ROHS3 Compliant status

Secondary Considerations:

• Panel cutout dimensions (rectangular format within tolerance range)
• Termination method compatibility with system requirements
• Number of positions and connector style variants

The identified substitutes (Qualtek 716W-X2/02 and SCHURTER 6600.4125) meet these core criteria while offering active product status and enhanced availability compared to the obsolete 718-10/28.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 716W-X2/02 is the manufacturer-recommended substitute, maintaining Qualtek brand continuity with active product status. This part offers CSA, TUV, and UL approvals, exceeding the original certification scope. The connector style transitions from IEC 320-2-2/H to IEC 320-2-2/F with an increase from 2 to 3 positions. Panel cutout dimensions remain within comparable tolerances. The quick connect termination increases from 0.110" to 0.189" (2.8mm to 4.8mm), requiring termination method evaluation for system compatibility.

SCHURTER 6600.4125 provides an alternative from an established manufacturer with active product status and comprehensive international approvals (CCC, cULus, ENEC). This connector features solder eyelet termination, requiring different assembly methodology compared to the quick connect approach. The part includes a light pipe feature and achieves IP30 ingress protection with UL94 V-0 material flammability rating. Panel thickness tolerance is fixed at 0.098" (2.50mm), which may require panel modification depending on original installation specifications.

Both substitutes maintain ROHS3 compliance and unfiltered commercial filter classification, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 716W-X2/02 directly replace the 718-10/28 in existing installations?

A: The 716W-X2/02 shares the same mounting type (panel mount, snap-in) and similar panel cutout dimensions. However, the termination method differs (0.189" quick connect versus 0.110" quick connect), and the connector style changes from IEC 320-2-2/H to IEC 320-2-2/F with an additional position. System integration requires evaluation of termination compatibility and connector pin configuration.

Q: What are the key differences between the two substitute options?

A: The Qualtek 716W-X2/02 maintains quick connect termination with a larger gauge (0.189"), while the SCHURTER 6600.4125 uses solder eyelet termination. The SCHURTER part includes additional features (light pipe, IP30 protection, UL94 V-0 rating) and accommodates thicker panels (0.098" fixed). Approval agencies differ, with SCHURTER offering broader international certifications.

Q: Are panel cutout modifications necessary for substitution?

A: The 718-10/28 specifies a rectangular cutout of 32.26mm x 24.77mm with 0.039" panel thickness. The 716W-X2/02 requires 32.60mm x 25.30mm with flexible panel thickness (0.031" to 0.059"), and the 6600.4125 requires 32.50mm x 24.80mm with fixed 0.098" thickness. Existing panel cutouts may require enlargement or modification depending on the selected substitute and original panel specifications.

Q: Do both substitutes maintain the same electrical ratings?

A: The original 718-10/28 does not specify current or voltage ratings. Both substitutes are rated for 10A at 250VAC, providing defined electrical parameters for system design and safety compliance.

Q: What termination method should be selected for new designs?

A: The choice between quick connect (716W-X2/02 at 0.189") and solder eyelet (6600.4125) depends on assembly process requirements and system architecture. Quick connect termination enables faster assembly and field replacement, while solder eyelet termination provides permanent mechanical connection suitable for high-vibration environments.
