Substitute Part Grouping Explanation

Substitute parts for the D4GL-1GFG-A are identified from the Omron D4SL-N series based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Circuit configuration: 3PST-NC + DPST-NO/NC
• Voltage supply: 24VDC
• Actuator type: Panel Disconnect
• Ingress protection: IP67
• Operating temperature range: -10°C to 55°C
• Status indicator feature
• Solenoid locking type

Substitution Considerations: The D4SL-N series substitutes differ in holding force (6kgf versus 102kgf), current ratings, and voltage load specifications. These differences require application-level evaluation based on specific load requirements. The D4SL-N4GFG-DN variant offers connector termination, while D4SL-N4GFG-D provides screw terminal termination matching the original part's connection method.

Engineering Selection Recommendations

D4SL-N4GFG-D (Screw Terminal): This substitute maintains screw terminal termination identical to the original D4GL-1GFG-A. The part is in active production status with current regulatory approvals including CCC, CE, cURus, and TUV certifications. Selection of this variant is appropriate when existing wiring harnesses and installation procedures utilize screw terminal connections.

D4SL-N4GFG-DN (Connector Termination): This substitute provides the same electrical circuit configuration and operational parameters as the D4SL-N4GFG-D but with connector-based termination. Active production status and equivalent regulatory approvals apply. This variant is suitable for applications where connector-based integration is preferred or required.

Both D4SL-N series substitutes provide active product status, ensuring long-term availability and supply chain continuity compared to the obsolete D4GL-1GFG-A.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between the D4GL-1GFG-A and D4SL-N substitutes?

A: The D4GL-1GFG-A features a 102kgf holding force and 240VAC rated load capacity. The D4SL-N series provides 6kgf holding force and 120VAC/125VDC rated load capacity. Both maintain identical circuit configuration (3PST-NC + DPST-NO/NC), 24VDC supply voltage, IP67 protection, and panel disconnect actuator type. Application requirements determine whether the reduced holding force and voltage rating of the D4SL-N series are acceptable.

Q: Which D4SL-N variant should I select?

A: Choose D4SL-N4GFG-D if your installation uses screw terminal connections. Choose D4SL-N4GFG-DN if connector-based termination is required. Both variants are electrically and functionally equivalent; the difference is termination method only.

Q: Are the D4SL-N substitutes compatible with existing installations designed for the D4GL-1GFG-A?

A: Compatibility depends on application load requirements. The D4SL-N series reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC/125VDC versus 240VAC) must be verified against your specific system requirements. Circuit configuration and control voltage (24VDC) are identical.

Q: What regulatory approvals apply to the substitute parts?

A: Both D4SL-N4GFG-D and D4SL-N4GFG-DN carry CCC, CE, cURus, and TUV approvals. The original D4GL-1GFG-A carried CE, cULus, and TUV approvals. Verify that substitute approvals meet your regional compliance requirements.

Q: Is the D4SL-N series actively manufactured?

A: Yes. Both D4SL-N4GFG-D and D4SL-N4GFG-DN are in active production status, ensuring availability for current and future orders. The original D4GL-1GFG-A is obsolete.
