Key Parameters

Substitute Part Grouping Explanation

The D4GL-2CFG-A has been superseded by components from the D4SL-N series. Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C to 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof

Allowable Variations:

• Current Rating: The D4SL-N series supports 1.5A (AC) and 220mA (DC), which accommodates the original 750mA AC requirement within the same electrical class
• Voltage Rating: The D4SL-N series operates at 120VAC and 125VDC, representing a different voltage class than the original 240VAC specification
• Holding Force: The D4SL-N series provides 6kgf, which is lower than the original 102kgf specification
• Termination Style: Available in both Screw Terminal and Connector options
• Product Status: D4SL-N series components are Active, ensuring ongoing availability

The D4SL-N2CFG and D4SL-N2CFG-N variants maintain functional equivalence through shared circuit topology, mechanical interface, and environmental protection ratings while differing in termination methodology and electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2CFG (Screw Terminal Configuration)

The D4SL-N2CFG is the direct functional equivalent for applications requiring screw terminal connectivity. This variant maintains the same termination interface as the original D4GL-2CFG-A, simplifying installation in existing wiring harnesses. The D4SL-N2CFG is an active product with current inventory availability (1050 pcs), ensuring supply chain continuity. Compliance certifications include CCC, CE, cURus, and TUV, providing broader regulatory coverage than the original component.

D4SL-N2CFG-N (Connector Configuration)

The D4SL-N2CFG-N provides equivalent functionality with connector-based termination, suitable for applications where modular connection is preferred. This variant is also an active product with confirmed inventory (680 pcs). The connector termination style eliminates the need for field wiring, reducing assembly time and potential connection errors in panel disconnect applications.

Electrical Rating Considerations

Both D4SL-N variants operate at 120VAC and 125VDC, which differs from the original 240VAC specification. Applications requiring 240VAC operation must evaluate whether the lower voltage rating is compatible with system design. The increased AC current capacity (1.5A versus 750mA) provides additional margin for switching loads.

Mechanical Force Consideration

The D4SL-N series provides 6kgf holding force compared to the original 102kgf. Applications dependent on the higher holding force specification require engineering evaluation to determine if the reduced force is acceptable for the intended mechanical load.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2CFG directly replace the D4GL-2CFG-A in all applications?

A: The D4SL-N2CFG maintains functional equivalence for circuit topology, mechanical interface, and environmental protection. However, the reduced holding force (6kgf versus 102kgf) and different voltage rating (120VAC/125VDC versus 240VAC) require application-specific evaluation. Verify that your system design accommodates these parameter differences before implementation.

Q: What is the difference between D4SL-N2CFG and D4SL-N2CFG-N?

A: Both variants are electrically and mechanically identical. The primary difference is termination style: D4SL-N2CFG uses screw terminals for field wiring, while D4SL-N2CFG-N uses a connector interface for modular connection. Select based on your panel disconnect assembly requirements and existing wiring infrastructure.

Q: Why does the D4SL-N series have lower holding force than the D4GL-2CFG-A?

A: The D4SL-N series represents a different product generation with revised mechanical specifications. The 6kgf holding force is the specified value for this series. Applications requiring 102kgf holding force must evaluate whether this reduction impacts mechanical safety or operational requirements.

Q: Are the D4SL-N variants compatible with the same supply voltage as the original?

A: No. The D4GL-2CFG-A operates on 24VDC supply with 240VAC switching capability. The D4SL-N variants operate at 120VAC and 125VDC. Verify that your power supply and circuit design are compatible with the D4SL-N voltage specifications before substitution.

Q: What certifications do the substitute parts carry?

A: The D4SL-N2CFG and D4SL-N2CFG-N carry CCC, CE, cURus, and TUV certifications. The original D4GL-2CFG-A carried CE, cULus, and TUV certifications. The D4SL-N variants provide expanded regulatory compliance coverage suitable for international applications.

Q: Is inventory available for the substitute parts?

A: Yes. D4SL-N2CFG has 1050 pcs in stock, and D4SL-N2CFG-N has 680 pcs in stock. Both are active products with confirmed ongoing availability from Omron Automation and Safety.
