Omron D4GL-4FFA-A Interlock Solenoid Release Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4FFA-A is a 3PST interlock solenoid release switch designed for panel disconnect applications. This part operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The D4GL-4FFA-A is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new installations.

Substitute parts must maintain functional compatibility across circuit configuration, voltage ratings, supply voltage, actuator type, termination compatibility, and environmental specifications to ensure reliable operation in interlock safety applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4FFA-A must satisfy the following criteria:

Mandatory Compatibility Parameters:

• Circuit configuration: 3PST-2NC/1NO + DPST-NC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Conduit thread size: M20
• Operating temperature range: -10°C ~ 55°C
• Ingress protection: IP67
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Current rating: Substitute parts may have equal or higher AC current capacity
• Voltage rating: Substitute parts may operate at different AC voltage ratings provided the 24VDC supply requirement is maintained
• Termination style: Screw terminal or connector termination are both acceptable
• Approval agencies: Substitute parts must maintain equivalent or broader certification coverage

The D4SL-N series parts (D4SL-N4FFA-D and D4SL-N4FFA-DN) meet all mandatory compatibility parameters while offering active product status and enhanced current ratings.

Engineering Selection Recommendations

D4SL-N4FFA-D (Screw Terminal)

This substitute is suitable for applications requiring direct replacement with screw terminal connections. The D4SL-N4FFA-D maintains identical termination style to the original D4GL-4FFA-A, simplifying installation in existing wiring configurations. Active product status ensures long-term availability and supply chain continuity. Enhanced current rating (1.5A AC vs. 750mA) provides operational margin. Broader certification coverage (CCC, CE, cURus, TUV) supports global deployment requirements.

D4SL-N4FFA-DN (Connector Termination)

This substitute is appropriate for applications where connector-based termination is acceptable or preferred. The D4SL-N4FFA-DN offers identical functional and environmental specifications to the D4SL-N4FFA-D with connector termination instead of screw terminals. This configuration may reduce installation time in modular or frequently reconfigured systems.

Selection Criteria:

Choose D4SL-N4FFA-D when existing installations use screw terminal connections and direct wiring compatibility is required. Choose D4SL-N4FFA-DN when connector-based termination aligns with system architecture or when rapid connection/disconnection capability is beneficial.

Both D4SL-N series parts satisfy all mandatory compatibility requirements for the D4GL-4FFA-A application.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4FFA-D or D4SL-N4FFA-DN be used as direct replacements for D4GL-4FFA-A?

A: Yes. Both parts maintain identical circuit configuration (3PST-2NC/1NO + DPST-NC), supply voltage (24VDC), actuator type (Panel Disconnect), conduit thread size (M20), operating temperature range (-10°C ~ 55°C), and ingress protection (IP67). The primary difference is termination style: D4SL-N4FFA-D uses screw terminals matching the original, while D4SL-N4FFA-DN uses connector termination.

Q: What is the difference between D4SL-N4FFA-D and D4SL-N4FFA-DN?

A: The parts are functionally identical except for termination style. D4SL-N4FFA-D features screw terminal connections; D4SL-N4FFA-DN features connector termination. Select based on your wiring infrastructure and installation requirements.

Q: Why does the D4SL-N series have lower holding force (6kgf vs. 102kgf)?

A: Holding force is a design characteristic of the solenoid mechanism and does not affect substitution eligibility. The D4SL-N series is engineered for the same panel disconnect application with different mechanical specifications. Application requirements determine whether the 6kgf holding force is adequate for your system.

Q: Are the D4SL-N parts certified for the same markets as the D4GL-4FFA-A?

A: The D4SL-N series carries broader certification (CCC, CE, cURus, TUV) compared to the D4GL-4FFA-A (CE, cULus, TUV). This expanded certification coverage supports deployment in additional regulatory jurisdictions.

Q: What is the current rating difference, and does it affect compatibility?

A: The D4GL-4FFA-A is rated for 750mA AC; the D4SL-N series is rated for 1.5A AC and 220mA DC. Higher current ratings indicate enhanced capacity and do not create compatibility issues. The D4SL-N series can safely handle applications within the D4GL-4FFA-A current specification.

Q: Is the D4GL-4FFA-A still available?

A: The D4GL-4FFA-A is classified as obsolete. The D4SL-N4FFA-D and D4SL-N4FFA-DN are active products with confirmed inventory availability, ensuring reliable supply for new installations and ongoing maintenance.
