D4GL-4FFG-A Equivalent & Substitute Parts

Part Overview

The D4GL-4FFG-A is an interlock solenoid locking switch manufactured by Omron Automation and Safety. This 3PST device features a 24VDC supply voltage, 240VAC rated switching capacity at 750mA, and a holding force of 102kgf. The unit is designed for panel disconnect applications with screw terminal connections and IP67 ingress protection. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance and new installations requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4FFG-A are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching 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

Allowable Variations:

• Termination style (screw terminal vs. connector)
• Current and voltage ratings (substitutes may have different AC/DC current and voltage specifications)
• Holding force (substitutes may have reduced holding force)
• Product status (active substitutes replace obsolete main part)

The D4SL-N series parts meet these substitution criteria while offering active product status and current manufacturing support.

Engineering Selection Recommendations

D4SL-N4FFG-D (Screw Terminal Configuration)

This substitute maintains screw terminal termination identical to the D4GL-4FFG-A. The D4SL-N4FFG-D is an active product with current manufacturing support and expanded regulatory approvals including CCC certification. The reduced holding force of 6kgf versus 102kgf represents a significant mechanical difference that must be evaluated against application requirements. The lower voltage and current ratings (120VAC/125VDC, 1.5A AC/220mA DC) differ from the original 240VAC/750mA specification and require verification of compatibility with existing circuit designs.

D4SL-N4FFG-DN (Connector Configuration)

This substitute provides identical electrical and mechanical specifications to the D4SL-N4FFG-D but uses connector termination instead of screw terminals. Selection of this variant depends on installation requirements and existing wiring infrastructure. Like the D4SL-N4FFG-D, this part is active and carries expanded regulatory approvals.

Both substitutes share the same circuit configuration, supply voltage, actuator type, conduit thread size, operating temperature range, and ingress protection as the original D4GL-4FFG-A, establishing functional compatibility for panel disconnect solenoid locking applications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N series parts directly replace the D4GL-4FFG-A?

A: The D4SL-N4FFG-D and D4SL-N4FFG-DN maintain the same 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). However, the holding force is reduced from 102kgf to 6kgf, and voltage/current ratings differ. Application-specific requirements must be evaluated before substitution.

Q: What is the difference between D4SL-N4FFG-D and D4SL-N4FFG-DN?

A: The primary difference is termination style. The D4SL-N4FFG-D uses screw terminals, matching the original D4GL-4FFG-A configuration. The D4SL-N4FFG-DN uses connector termination. Both parts are electrically and mechanically identical otherwise.

Q: Why does the D4SL-N series have lower holding force than the D4GL-4FFG-A?

A: The D4SL-N series is a different product line within the Omron solenoid locking switch portfolio. The 6kgf holding force of the D4SL-N series is a design characteristic of this series. Applications requiring 102kgf holding force may not be compatible with this substitute.

Q: Are the voltage and current ratings compatible with my existing installation?

A: The D4GL-4FFG-A is rated for 240VAC at 750mA. The D4SL-N series is rated for 120VAC/125VDC at 1.5A (AC) or 220mA (DC). These specifications differ and must be verified against your circuit design and power supply configuration before substitution.

Q: What regulatory approvals do the substitute parts carry?

A: Both D4SL-N4FFG-D and D4SL-N4FFG-DN carry CCC, CE, cURus, and TUV approvals, providing expanded regulatory coverage compared to the original D4GL-4FFG-A (CE, cULus, TUV).

Q: Is inventory availability a factor in selecting a substitute?

A: The D4SL-N4FFG-D has 1034 units in stock and the D4SL-N4FFG-DN has 912 units in stock, both offering active product status with ongoing manufacturing support, unlike the obsolete D4GL-4FFG-A.
