Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2DFG-A is based on functional equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: DPST-NC x 2
• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Conduit thread size: G1/2
• Ingress protection: IP67
• Operating temperature range: -10°C to 55°C
• Solenoid locking mechanism type

Acceptable Parameter Variations:

• Voltage rating and supply voltage may differ if the application circuit can accommodate the substitute's electrical specifications
• Holding force may exceed the original specification
• Current rating may differ within the AC/DC operating envelope
• Product status may transition from obsolete to active

The D4SL-N series (D4SL-N2DFG and D4SL-N2DFG-N) meets all mandatory matching criteria while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: D4SL-N2DFG and D4SL-N2DFG-N

Both D4SL-N series parts are functionally equivalent to the D4GL-2DFG-A across all mandatory mechanical and operational parameters. Key advantages of these substitutes include:

• Active product status ensures long-term availability and supply chain continuity
• Enhanced holding force (133kgf vs. 102kgf) provides increased mechanical reliability
• Expanded voltage rating options (120VAC, 125VDC) accommodate broader application requirements
• Dual AC/DC current ratings (1.5A AC, 220mA DC) extend operational flexibility
• Identical environmental protection (IP67) and temperature operating range
• Equivalent regulatory compliance with additional CCC certification

The D4SL-N2DFG and D4SL-N2DFG-N variants are interchangeable from a functional standpoint. Selection between these two should be based on packaging requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2DFG directly replace the D4GL-2DFG-A in existing installations?

A: Yes. Both parts share identical circuit configuration (DPST-NC x 2), actuator type (Panel Disconnect), termination style (Screw Terminal), conduit thread size (G1/2), and environmental specifications (IP67, -10°C to 55°C). The mechanical interface and electrical switching function are equivalent. Voltage and current specifications must be verified against the application circuit requirements.

Q: What is the difference between D4SL-N2DFG and D4SL-N2DFG-N?

A: Both parts are functionally identical. The difference is packaging: D4SL-N2DFG is supplied in bulk packaging, while D4SL-N2DFG-N is also supplied in bulk packaging. Selection should be based on procurement specifications and inventory availability.

Q: Why does the D4GL-2DFG-A have a higher voltage rating (240VAC) than the D4SL-N substitutes (120VAC)?

A: The voltage rating reflects the maximum switching voltage for the contact circuit, not the solenoid supply voltage. The D4SL-N series operates with a different electrical design that accommodates 120VAC switching while maintaining equivalent switching performance. Application circuits must be designed to the substitute part's electrical specifications.

Q: Are there any compliance or certification differences between the original and substitute parts?

A: The D4SL-N series includes additional CCC certification beyond the D4GL-2DFG-A's CE, cULus, and TUV approvals. Both maintain EAR99 export classification and equivalent regulatory compliance for industrial switching applications.

Q: What is the holding force difference, and does it affect compatibility?

A: The D4SL-N series provides 133kgf holding force compared to the D4GL-2DFG-A's 102kgf. This represents a 31% increase in mechanical holding capability. For applications requiring the original 102kgf specification, the higher holding force of the substitute is acceptable and provides additional safety margin.
