D4GL-4EFA-A Equivalent & Substitute Parts

Part Overview

The D4GL-4EFA-A is an interlock solenoid release manufactured by Omron Automation and Safety, classified as a 3PST switch with combined circuit configuration (3PST-2NC/1NO + DPST-NO/NC). This component is designed for panel disconnect applications with a 24VDC supply voltage and 240VAC rated switching capacity at 750mA. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance and new installations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-4EFA-A is based on the following critical parameters that must align across equivalent parts:

• Circuit configuration: 3PST-2NC/1NO + DPST-NO/NC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Conduit thread size: M20
• Ingress protection: IP67
• Operating temperature range: -10°C ~ 55°C
• Termination compatibility with system requirements

The D4SL-N series substitutes (D4SL-N4EFA-D and D4SL-N4EFA-DN) maintain identical circuit configuration, supply voltage, actuator type, conduit thread size, temperature range, and IP67 rating. Both substitute parts are active products from Omron, ensuring continued availability and support. The primary difference between substitutes is termination style: D4SL-N4EFA-D uses screw terminals (matching the original), while D4SL-N4EFA-DN uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4EFA-D and D4SL-N4EFA-DN are active products with current manufacturing status, providing long-term availability compared to the obsolete D4GL-4EFA-A. The D4SL-N series carries expanded regulatory approvals (CCC, CE, cURus, TUV) versus the original part (CE, cULus, TUV), supporting broader market compliance requirements.

For direct replacement in existing installations with screw terminal connections, D4SL-N4EFA-D is the appropriate selection. For new designs or systems requiring connector-based termination, D4SL-N4EFA-DN provides equivalent functionality with alternative connection methodology.

Note that the D4SL-N series exhibits reduced holding force (6kgf versus 102kgf) and different voltage/current ratings (120VAC/125VDC at 1.5A AC, 220mA DC versus 240VAC at 750mA AC). These parameter differences must be evaluated against specific application requirements to ensure functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4EFA-D directly replace D4GL-4EFA-A in existing installations?

A: D4SL-N4EFA-D maintains identical circuit configuration, supply voltage, actuator type, conduit thread size, temperature range, and IP67 rating. Screw terminal termination matches the original part. However, the reduced holding force (6kgf versus 102kgf) and different voltage/current ratings must be verified against application specifications before installation.

Q: What is the difference between D4SL-N4EFA-D and D4SL-N4EFA-DN?

A: Both parts are functionally equivalent with identical electrical specifications and circuit configuration. The primary difference is termination style: D4SL-N4EFA-D uses screw terminals, while D4SL-N4EFA-DN uses connector termination. Selection depends on the connection methodology required by the system.

Q: Why do the substitute parts have lower holding force than the original?

A: The D4SL-N series is a different product line within Omron's solenoid release portfolio. While maintaining the same circuit configuration and core functionality, the D4SL-N series is designed with different mechanical specifications. Application requirements must be assessed to determine if the 6kgf holding force is sufficient for the intended use case.

Q: Are the substitute parts compatible with the same regulatory environments?

A: The D4SL-N series carries CE, cURus, and TUV approvals, with additional CCC certification. These certifications support compliance in multiple regulatory jurisdictions. Verify that the specific certifications required for your application are present in the substitute part documentation.

Q: What inventory status should be considered for procurement?

A: D4SL-N4EFA-D has 691 units in stock, and D4SL-N4EFA-DN has 726 units in stock, both listed as new original inventory. The D4GL-4EFA-A, being obsolete, has 756 units available but no future manufacturing support.
