D4GL-4FFA-A4 Equivalent & Substitute Parts

Part Overview

The D4GL-4FFA-A4 is an interlock solenoid release manufactured by Omron Automation and Safety, configured as a 3PST switch with combined 2NC/1NO and DPST-NC circuits. This component is designed for panel disconnect applications requiring 24VDC supply voltage and 240VAC switching capability at 750mA. The part is currently obsolete, making identification of functionally equivalent active alternatives essential for system maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-4FFA-A4 is determined by the following critical parameters:

• Circuit configuration (3PST-2NC/1NO + DPST-NC)
• Supply voltage compatibility (24VDC)
• Switching voltage and current ratings
• Holding force capability
• Actuator type (Panel Disconnect)
• Conduit thread size (M20)
• Environmental ratings (IP67, operating temperature range)
• Approval certifications

The D4SL-N series represents the active product line replacement for the obsolete D4GL series. Both substitute parts maintain the required circuit topology, M20 conduit interface, and IP67 environmental protection. However, electrical ratings and holding force characteristics differ and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4FFA-D4: This substitute maintains screw terminal connectivity matching the original D4GL-4FFA-A4 termination style. The D4SL-N4FFA-D4 provides higher holding force (133kgf versus 102kgf) and increased AC current capacity (1.5A versus 750mA). The reduced AC voltage rating (120VAC versus 240VAC) requires verification against application voltage requirements. This part is active and carries expanded certifications (CCC addition). Supply voltage specification is not provided; clarification is required before selection.

D4SL-N4FFA-D4N: This substitute features connector termination rather than screw terminals, representing a mechanical interface change. The holding force is significantly reduced to 6kgf, unsuitable for applications requiring the original 102kgf specification. The D4SL-N4FFA-D4N explicitly specifies 24VDC supply voltage compatibility and maintains 120VAC switching at 1.5A. This configuration is appropriate only for applications where reduced holding force is acceptable and connector termination is compatible with system design.

Selection between D4SL-N4FFA-D4 and D4SL-N4FFA-D4N depends on termination interface requirements and holding force specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Why is the D4GL-4FFA-A4 being discontinued? A: The D4GL-4FFA-A4 is classified as obsolete. The D4SL-N series represents the current active product line from Omron for this solenoid release category.

Q: Can D4SL-N4FFA-D4 directly replace D4GL-4FFA-A4? A: Direct replacement requires verification of three parameters: (1) supply voltage compatibility—the D4SL-N4FFA-D4 supply voltage is not specified in available data; (2) AC voltage rating—the substitute operates at 120VAC versus the original 240VAC; (3) termination interface—both use screw terminals, ensuring mechanical compatibility.

Q: What is the primary difference between D4SL-N4FFA-D4 and D4SL-N4FFA-D4N? A: The D4SL-N4FFA-D4 uses screw terminal connectivity, while D4SL-N4FFA-D4N uses connector termination. Additionally, D4SL-N4FFA-D4N specifies 24VDC supply voltage and provides significantly lower holding force (6kgf versus 133kgf).

Q: Is the holding force difference between substitutes significant? A: Yes. The D4SL-N4FFA-D4 provides 133kgf holding force, exceeding the original 102kgf specification. The D4SL-N4FFA-D4N provides only 6kgf, a substantial reduction. Application requirements determine which holding force is acceptable.

Q: Are certifications equivalent between the original and substitute parts? A: The original D4GL-4FFA-A4 carries CE, cULus, and TUV certifications. Both D4SL-N substitutes carry CCC, CE, cURus, and TUV certifications. The D4SL-N series includes additional CCC certification and cURus (versus cULus) designation.

Q: What supply voltage should be specified for the D4SL-N4FFA-D4? A: The D4SL-N4FFA-D4 supply voltage is not provided in available technical data. The D4SL-N4FFA-D4N explicitly specifies 24VDC. Clarification from Omron or system documentation is required before selecting the D4 variant.
