D4GL-2DFA-A Equivalent & Substitute Parts

Part Overview

The D4GL-2DFA-A is an interlock solenoid release switch manufactured by Omron Automation and Safety. This DPST-NC component is designed for panel disconnect applications with a 24VDC supply voltage and 240VAC load rating. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-2DFA-A are identified from the D4SL-N series based on the following allowable parameters:

Common Parameters (Substitution Basis):

• Circuit Configuration: DPST-NC x 2
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Manufacturer: Omron Automation and Safety

Identified Substitutes:

• D4SL-N2DFA (Screw Terminal variant)
• D4SL-N2DFA-N (Connector variant)

Both substitutes maintain the same circuit topology, environmental ratings, and mechanical interface specifications as the original D4GL-2DFA-A.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2DFA is the primary substitute for applications requiring screw terminal connections. This part maintains identical termination style to the original D4GL-2DFA-A and carries active product status with expanded regulatory approvals (CCC, CE, cURus, TUV).

D4SL-N2DFA-N is the substitute for applications requiring connector-based termination. This variant provides the same electrical and mechanical specifications as D4SL-N2DFA but with connector termination instead of screw terminals.

Both substitutes are manufactured by Omron Automation and Safety and are currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete D4GL-2DFA-A.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2DFA or D4SL-N2DFA-N directly replace D4GL-2DFA-A in existing installations?

A: Both D4SL-N series parts maintain the same circuit configuration (DPST-NC x 2), actuator type (Panel Disconnect), and mechanical interface (G1/2 conduit thread). Selection between D4SL-N2DFA and D4SL-N2DFA-N depends on termination requirements: use D4SL-N2DFA for screw terminal applications or D4SL-N2DFA-N for connector-based installations.

Q: What are the key differences between D4SL-N2DFA and D4SL-N2DFA-N?

A: The primary difference is termination style. D4SL-N2DFA uses screw terminals, while D4SL-N2DFA-N uses connector termination. All other electrical and mechanical parameters are identical.

Q: Are the D4SL-N substitutes compatible with the original supply voltage and load specifications?

A: The D4SL-N series operates at different voltage ratings (120VAC, 125VDC supply) compared to the D4GL-2DFA-A (24VDC supply, 240VAC load). System integration requires verification that the substitute part's voltage specifications align with the application's power supply and load requirements.

Q: What regulatory approvals do the substitute parts carry?

A: Both D4SL-N2DFA and D4SL-N2DFA-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-2DFA-A (CE, cULus, TUV).
