Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-1GFG-A4 are identified from the D4SL-N series based on the following electrical and mechanical compatibility criteria:

Preserved Parameters (Substitution Basis):

• Circuit configuration: 3PST-NC + DPST-NO/NC
• Actuator type: Panel Disconnect
• Supply voltage: 24VDC
• Features: Status Indicator
• Ingress protection: IP67
• Operating temperature range: -10°C ~ 55°C
• Manufacturer: Omron Automation and Safety

Differing Parameters (Engineering Considerations):

• Current rating: D4SL-N series rated 1.5A (AC) and 220mA (DC) versus D4GL-1GFG-A4 at 750mA (AC)
• Voltage rating: D4SL-N series rated 120VAC/125VDC versus D4GL-1GFG-A4 at 240VAC
• Holding force: D4SL-N series provides 6kgf versus D4GL-1GFG-A4 at 102kgf
• Conduit thread size: D4SL-N series uses M20 versus D4GL-1GFG-A4 at PG14.6
• Termination style: D4SL-N4GFG-D4N uses Connector; D4SL-N4GFG-D4 uses Screw Terminal

Two substitute parts are identified within the D4SL-N series, differentiated by termination style.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4GFG-D4 (Screw Terminal)

This substitute maintains screw terminal termination matching the original D4GL-1GFG-A4 configuration. The D4SL-N4GFG-D4 is currently in active production status, ensuring long-term availability and supply chain stability. It carries CE, cURus, and TUV certifications alongside CCC approval. RoHS compliance is confirmed. This part is suitable for applications where screw terminal connection is required and the reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC/125VDC versus 240VAC) are acceptable within system design parameters.

D4SL-N4GFG-D4N (Connector Termination)

This substitute provides connector-based termination, offering an alternative to screw terminal connection. The D4SL-N4GFG-D4N is in active production with identical certifications (CE, cURus, TUV, CCC) and RoHS compliance. Selection of this variant is appropriate for applications where connector termination is preferred or required by system design. The same electrical and mechanical parameter considerations apply as with the D4SL-N4GFG-D4.

Both substitutes represent active product lines from Omron, providing superior supply chain continuity compared to the obsolete D4GL-1GFG-A4.

Frequently Asked Questions (FAQ)

Q: Why are the D4SL-N series parts considered equivalent to the D4GL-1GFG-A4?

A: Both series share identical circuit configuration (3PST-NC + DPST-NO/NC), actuator type (Panel Disconnect), supply voltage (24VDC), status indicator feature, IP67 ingress protection, and operating temperature range. These parameters define the functional role of the component within a system. The D4SL-N series represents the current-generation equivalent from Omron for this functional category.

Q: What are the key differences between D4SL-N4GFG-D4 and D4SL-N4GFG-D4N?

A: The primary difference is termination style. D4SL-N4GFG-D4 uses screw terminals, matching the original D4GL-1GFG-A4 configuration. D4SL-N4GFG-D4N uses connector termination. Both parts are electrically and mechanically identical otherwise. Selection depends on whether your system requires screw terminal or connector connection.

Q: Can I use D4SL-N parts in place of D4GL-1GFG-A4 if my application requires 240VAC operation?

A: The D4SL-N series is rated for 120VAC/125VDC operation, not 240VAC. If your application specifically requires 240VAC operation as specified for the D4GL-1GFG-A4, the D4SL-N series does not meet this voltage requirement. Consult Omron for alternative solutions rated for 240VAC operation.

Q: What is the holding force difference, and does it matter for substitution?

A: The D4GL-1GFG-A4 provides 102kgf holding force, while D4SL-N series provides 6kgf. Holding force determines the mechanical locking capability. Substitution is valid only if your application can function with the reduced 6kgf holding force. If maximum holding force is a critical system requirement, the D4SL-N series may not be suitable.

Q: Are both substitute parts currently available?

A: Yes. D4SL-N4GFG-D4 has 1103 units in stock, and D4SL-N4GFG-D4N has 767 units in stock. Both are active products from Omron, ensuring ongoing availability.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N4GFG-D4 and D4SL-N4GFG-D4N carry CE, cURus, TUV, and CCC certifications. Both are RoHS compliant. The original D4GL-1GFG-A4 carried CE, cULus, and TUV certifications.
