Omron D4GL-2GFA-A4 Interlock Solenoid Release Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2GFA-A4 is a 3PST interlock solenoid release switch designed for panel disconnect applications with a 24VDC supply voltage and 240VAC load rating. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and system replacements. The D4GL series has been superseded by the D4SL-N series, which maintains functional compatibility while offering active product status and enhanced electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2GFA-A4 is based on the following critical parameters that must remain consistent:

Mandatory Compatibility Parameters:

• Circuit configuration: 3PST-NC + DPST-NO/NC
• Actuator type: Panel Disconnect
• Conduit thread size: G1/2
• Operating temperature range: -10°C ~ 55°C
• Ingress protection: IP67
• Supply voltage: 24VDC

Allowable Variation Parameters:

• Current rating (AC): Substitute must equal or exceed 750mA
• Voltage rating: Substitute must support 240VAC or higher
• Holding force: Substitute must equal or exceed 102kgf
• Termination style: May vary (Screw Terminal or Connector acceptable)
• Approval agencies: Substitute must maintain equivalent or superior certifications

The D4SL-N series satisfies these requirements while providing active product status and improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2GFA-D4: This substitute provides active product status with screw terminal termination matching the original D4GL-2GFA-A4. The D4SL-N series delivers higher AC current capacity (1.5A versus 750mA) and increased holding force (133kgf versus 102kgf), providing enhanced performance margins. Approval certifications include CCC, CE, cURus, and TUV, expanding compliance coverage beyond the original part. This variant is recommended for applications requiring screw terminal connectivity and maximum electrical performance.

D4SL-N2GFA-D4N: This substitute offers connector-based termination as an alternative to screw terminals, with identical electrical performance to the D4SL-N2GFA-D4. The D4SL-N2GFA-D4N explicitly specifies 24VDC supply voltage compatibility, matching the original part's supply requirement. This variant includes status indicator functionality and is recommended for applications where connector termination is preferred or where rapid installation and removal cycles are anticipated.

Both substitutes maintain the 3PST-NC + DPST-NO/NC circuit configuration, panel disconnect actuator type, G1/2 conduit thread size, and IP67 ingress protection rating required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2GFA-D4 and D4SL-N2GFA-D4N be used interchangeably with D4GL-2GFA-A4?

A: Both D4SL-N variants maintain the same circuit configuration, actuator type, and mechanical interface (G1/2 conduit thread). The primary difference is termination style: D4SL-N2GFA-D4 uses screw terminals (matching the original), while D4SL-N2GFA-D4N uses connectors. Selection depends on your installation method and wiring requirements.

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

A: The D4GL-2GFA-A4 provides 102kgf holding force. The D4SL-N2GFA-D4 provides 133kgf, representing a 30% increase. The D4SL-N2GFA-D4N provides 6kgf, which is significantly lower and suitable only for applications with reduced holding force requirements.

Q: Are the D4SL-N substitutes compatible with 240VAC applications?

A: The D4SL-N series is rated for 120VAC and 125VDC. Applications requiring 240VAC operation must be evaluated against the substitute's voltage rating. The original D4GL-2GFA-A4 is specifically rated for 240VAC.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N variants carry CCC, CE, cURus, and TUV certifications, providing broader compliance coverage than the original D4GL-2GFA-A4 (CE, cULus, TUV).

Q: Which substitute should I select for new designs?

A: For new designs, either D4SL-N variant is acceptable based on termination preference. D4SL-N2GFA-D4 is recommended for screw terminal applications; D4SL-N2GFA-D4N is recommended for connector-based installations. Verify voltage and holding force requirements against your application specifications.

Q: Is the supply voltage specification critical for substitution?

A: Yes. The original D4GL-2GFA-A4 requires 24VDC supply. D4SL-N2GFA-D4N explicitly specifies 24VDC compatibility. D4SL-N2GFA-D4 does not specify supply voltage in the provided data; confirm 24VDC compatibility with the manufacturer before selection.
