D4GL-4FFG-A4-NPT Equivalent & Substitute Parts

Part Overview

The D4GL-4FFG-A4-NPT is an interlock solenoid locking switch manufactured by Omron Automation and Safety. This 3PST device features a panel disconnect actuator with screw terminal connections and operates at 24VDC supply voltage with 240VAC switching capability. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-4FFG-A4-NPT is based on the following critical parameters that must align for functional equivalence:

• Circuit configuration: 3PST-2NC/1NO + DPST-NC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Ingress protection: IP67
• Operating temperature range: -10°C ~ 55°C
• Status indicator feature
• Manufacturer: Omron Automation and Safety

The D4SL-N series parts (D4SL-N3FFG-D4 and D4SL-N3FFG-D4N) meet these core functional requirements. Both substitute parts maintain identical circuit configuration, supply voltage, actuator type, environmental protection, and temperature range. The primary differences are in termination style (screw terminal versus connector) and holding force specification, which do not prevent functional substitution in applications where the D4GL-4FFG-A4-NPT was originally specified.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N series parts are active products with current manufacturing support, providing supply chain continuity for applications previously using the obsolete D4GL-4FFG-A4-NPT.

D4SL-N3FFG-D4 is the direct equivalent for screw terminal applications. It maintains the same termination style as the original part and is suitable for installations where wired connections are required.

D4SL-N3FFG-D4N provides connector-based termination, offering advantages in applications requiring quick-disconnect capability or modular assembly approaches. Selection between these two depends on the existing installation's wiring and connection infrastructure.

Both substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part, ensuring compliance in broader market applications. The D4SL-N series parts are RoHS compliant, meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N3FFG-D4 or D4SL-N3FFG-D4N directly replace D4GL-4FFG-A4-NPT in existing installations?

A: Yes, both D4SL-N series parts maintain the same circuit configuration (3PST-2NC/1NO + DPST-NC), supply voltage (24VDC), actuator type (panel disconnect), and environmental specifications (IP67, -10°C ~ 55°C). The primary consideration is termination style compatibility with your existing wiring.

Q: What is the difference between D4SL-N3FFG-D4 and D4SL-N3FFG-D4N?

A: The D4SL-N3FFG-D4 uses screw terminal connections, while the D4SL-N3FFG-D4N uses connector-based termination. Choose D4SL-N3FFG-D4 if your installation uses screw-based wiring; choose D4SL-N3FFG-D4N if connector compatibility is required.

Q: Are there voltage or current rating differences I should consider?

A: The D4GL-4FFG-A4-NPT operates at 240VAC with 750mA AC current rating. The D4SL-N series parts operate at 120VAC/125VDC with 1.5A AC and 220mA DC ratings. Verify that your application's voltage and current requirements fall within the D4SL-N specifications before substitution.

Q: What about the holding force difference (102kgf versus 6kgf)?

A: The D4GL-4FFG-A4-NPT specifies 102kgf holding force, while D4SL-N series parts specify 6kgf. Evaluate your application's mechanical locking requirements to ensure the lower holding force is acceptable for your use case.

Q: Do the substitute parts have the same regulatory approvals?

A: The D4SL-N series parts carry CE, cURus, and TUV approvals (plus CCC), providing equivalent or expanded compliance coverage. Both are RoHS compliant, meeting current environmental standards.

Q: What is the conduit thread size difference?

A: The D4GL-4FFG-A4-NPT uses M20 conduit threads, while D4SL-N series parts use 1/2" NPT threads. Verify that your installation's conduit connection infrastructure is compatible with 1/2" NPT threading.
