Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-2DFG-A4 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Circuit configuration: DPST-NC x 2 (dual-pole, single-throw normally closed)
• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Conduit thread size: G1/2
• Ingress protection: IP67 minimum
• Operating temperature range: -10°C ~ 55°C minimum

Electrical Compatibility Considerations:

• Current rating must accommodate or exceed 750mA AC requirement
• Voltage rating must support 240VAC operation or provide equivalent voltage class
• Supply voltage compatibility with 24VDC control circuit

Mechanical Compatibility:

• Holding force of 102kgf establishes minimum mechanical performance requirement
• Panel disconnect actuator type ensures mechanical interface compatibility

The D4SL-N series (D4SL-N2DFG and D4SL-N2DFG-N) meets all functional and mechanical substitution criteria. Both parts maintain identical circuit configuration, actuator type, termination style, and conduit thread size. The D4SL-N series provides enhanced electrical performance with 1.5A AC and 220mA DC current ratings, increased holding force of 133kgf, and active product status with current manufacturing support.

Engineering Selection Recommendations

Primary Recommendation: D4SL-N2DFG or D4SL-N2DFG-N

Both D4SL-N series parts are functionally equivalent substitutes for the obsolete D4GL-2DFG-A4. Selection between these two active alternatives should be based on:

Product Status: The D4SL-N series maintains active manufacturing status with Omron, ensuring long-term availability and supply chain continuity. The D4GL-2DFG-A4 obsolete status necessitates transition to an active equivalent.

Compliance and Certifications: The D4SL-N series carries expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part (CE, cULus, TUV), providing broader market compliance coverage.

Electrical Performance: The D4SL-N series provides enhanced current ratings (1.5A AC versus 750mA AC) and introduces DC current capability (220mA DC), expanding operational flexibility beyond the original specification.

Mechanical Performance: The D4SL-N series delivers 133kgf holding force, exceeding the original 102kgf specification, ensuring equivalent or superior mechanical performance in panel disconnect applications.

Packaging Consideration: Both substitute parts are supplied in bulk packaging. Verify packaging requirements for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2DFG and D4SL-N2DFG-N be used interchangeably as substitutes for D4GL-2DFG-A4?

A: Yes. Both parts are functionally equivalent substitutes. They share identical circuit configuration (DPST-NC x 2), actuator type (Panel Disconnect), termination style (Screw Terminal), conduit thread size (G1/2), operating temperature range (-10°C ~ 55°C), and ingress protection (IP67). Selection between them may depend on packaging requirements and inventory availability.

Q: What are the key differences between the original D4GL-2DFG-A4 and the D4SL-N substitute series?

A: The primary differences are product status (obsolete versus active), current ratings (750mA AC versus 1.5A AC), holding force (102kgf versus 133kgf), and regulatory approvals. The D4SL-N series also introduces DC current capability (220mA DC) not specified in the original part.

Q: Is the voltage rating difference between D4GL-2DFG-A4 (240VAC) and D4SL-N series (120VAC) a compatibility concern?

A: The voltage rating difference reflects different design specifications. The D4SL-N series is rated for 120VAC operation. Application voltage requirements must be evaluated against the substitute part's voltage rating to ensure proper system operation.

Q: Are the D4SL-N series parts suitable for the same mechanical mounting and panel disconnect applications as the original D4GL-2DFG-A4?

A: Yes. Both substitute parts maintain identical actuator type (Panel Disconnect), termination style (Screw Terminal), and conduit thread size (G1/2), ensuring mechanical compatibility with existing panel disconnect installations.

Q: What is the inventory status of the substitute parts?

A: D4SL-N2DFG has 680 pieces in stock. D4SL-N2DFG-N has 740 pieces in stock. Both are available as new original components.
