Equivalent & Substitute Parts for D4GL-1GFA-A

Part Overview

The D4GL-1GFA-A is an interlock solenoid release manufactured by Omron Automation and Safety, configured as a 3PST switch with integrated status indicator. This component is designed for panel disconnect applications requiring 24VDC supply with 240VAC switching capability at 750mA AC current rating and 102kgf holding force.

The D4GL-1GFA-A has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this component specification is required.

Substitute Part Grouping Explanation

Substitute parts for the D4GL-1GFA-A are identified based on the following critical parameters that define functional equivalence:

Circuit configuration: 3PST-NC + DPST-NO/NC
Actuator type: Panel Disconnect
Supply voltage: 24VDC
Ingress protection: IP67
Operating temperature range: -10°C ~ 55°C
Status indicator feature
Screw terminal or connector termination compatibility

The substitute parts D4SL-N4GFA-D and D4SL-N4GFA-DN maintain the same circuit topology, supply voltage, environmental protection rating, and temperature operating range. Both substitutes are active products from the same manufacturer, ensuring design continuity and availability. The primary differences are in current rating capacity, holding force specification, and termination style (screw terminal versus connector).

Engineering Selection Recommendations

Both D4SL-N4GFA-D and D4SL-N4GFA-DN are active products with current manufacturing status and expanded regulatory approvals including CCC certification. These substitutes maintain functional equivalence for panel disconnect solenoid release applications with 24VDC supply and IP67 environmental protection.

Selection between the two substitute options depends on termination requirements: D4SL-N4GFA-D provides screw terminal connection matching the original D4GL-1GFA-A termination style, while D4SL-N4GFA-DN uses connector termination for applications requiring quick-disconnect capability.

Applications requiring the original 240VAC switching voltage and 102kgf holding force specification should evaluate whether the substitute parts' 120VAC rating and 6kgf holding force meet the system requirements. The D4SL-N series provides higher AC current capacity (1.5A versus 750mA) and DC switching capability not specified in the original part.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4GFA-D and D4SL-N4GFA-DN be used interchangeably with D4GL-1GFA-A?

A: Both substitute parts maintain the same circuit configuration (3PST-NC + DPST-NO/NC), 24VDC supply voltage, IP67 protection, and operating temperature range. The primary difference is termination style: D4SL-N4GFA-D uses screw terminals identical to the original, while D4SL-N4GFA-DN uses connector termination. Selection depends on your wiring interface requirements.

Q: What are the key differences in electrical ratings?

A: The D4GL-1GFA-A is rated for 240VAC at 750mA with 102kgf holding force. The D4SL-N substitutes are rated for 120VAC at 1.5A AC (220mA DC) with 6kgf holding force. Applications requiring the original 240VAC switching voltage or 102kgf holding force must confirm the substitute ratings are acceptable for the intended circuit.

Q: Why is the D4GL-1GFA-A obsolete?

A: The D4GL-1GFA-A has reached end-of-life status. The D4SL-N series represents the current active product line from Omron for equivalent solenoid release functionality with enhanced certifications and availability.

Q: Are the substitute parts certified for the same applications?

A: Both substitute parts carry CE, TUV, and additional CCC and cURus certifications. The original D4GL-1GFA-A carried CE, cULus, and TUV approvals. Verify that the substitute part certifications meet your specific application and regional compliance requirements.

Q: What is the difference between bulk and other packaging options?

A: Both substitute parts are supplied in bulk packaging. Confirm packaging requirements for your procurement and inventory management processes.
