Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-1FFG-A4 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: 3PST-2NC/1NO + DPST-NC
• Voltage Supply: 24VDC
• Actuator Type: Panel Disconnect
• Ingress Protection: IP67
• Operating Temperature Range: -10°C ~ 55°C
• Features: Status Indicator
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Product Status: Active alternatives acceptable for obsolete part
• Current Rating: Substitute parts may have different AC/DC current ratings provided they meet or exceed application requirements
• Voltage Rating: Substitute parts may have different voltage ratings
• Holding Force: Substitute parts may have different holding force values
• Termination Style: Screw Terminal or Connector acceptable
• Approval Agencies: Substitute parts must maintain equivalent or broader certification coverage

The D4SL-N4FFG-D4 and D4SL-N4FFG-D4N meet all mandatory matching parameters and are classified as active products, making them suitable substitutes for the obsolete D4GL-1FFG-A4.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4FFG-D4 and D4SL-N4FFG-D4N are active products from Omron Automation and Safety and serve as direct functional equivalents to the obsolete D4GL-1FFG-A4. Selection between these two substitutes depends on termination requirements:

D4SL-N4FFG-D4 is specified with screw terminal termination, matching the original D4GL-1FFG-A4 configuration. This option provides continuity with existing wiring practices and installation procedures.

D4SL-N4FFG-D4N is specified with connector termination, offering alternative integration flexibility for applications where connector-based connections are preferred or required.

Both substitutes maintain equivalent circuit configuration, voltage supply, actuator type, ingress protection rating, operating temperature range, and status indicator functionality. Both carry expanded approval agency certifications (CCC, CE, cURus, TUV) compared to the original part, supporting broader regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4FFG-D4 or D4SL-N4FFG-D4N be used as direct replacements for D4GL-1FFG-A4?

A: Yes. Both substitute parts maintain identical circuit configuration (3PST-2NC/1NO + DPST-NC), voltage supply (24VDC), actuator type (Panel Disconnect), ingress protection (IP67), operating temperature range (-10°C ~ 55°C), and status indicator functionality. The primary difference is termination style: D4SL-N4FFG-D4 uses screw terminals matching the original, while D4SL-N4FFG-D4N uses connector termination.

Q: What are the differences in current and voltage ratings between the original and substitute parts?

A: The D4GL-1FFG-A4 is rated for 750mA AC at 240VAC. The D4SL-N4FFG-D4 and D4SL-N4FFG-D4N are rated for 1.5A AC at 120VAC and 220mA DC at 125VDC. These differences reflect design improvements in the D4SL-N series. Application-specific current and voltage requirements must be evaluated to confirm compatibility.

Q: What is the difference in holding force between the original and substitute parts?

A: The D4GL-1FFG-A4 provides 102kgf holding force, while D4SL-N4FFG-D4 and D4SL-N4FFG-D4N provide 6kgf holding force. Applications requiring the original 102kgf holding force specification must evaluate whether the reduced holding force of the substitute parts is acceptable for the intended use case.

Q: Which substitute part should be selected based on termination requirements?

A: Select D4SL-N4FFG-D4 if screw terminal connections are required, maintaining compatibility with existing wiring infrastructure. Select D4SL-N4FFG-D4N if connector-based termination is required or preferred for the application.

Q: Are the substitute parts certified to the same standards as the original?

A: The substitute parts carry expanded certification coverage (CCC, CE, cURus, TUV) compared to the original part (CE, cULus, TUV). Both substitute parts maintain TUV and CE certifications present in the original specification.
