D4GL-2FFG-A4 Equivalent & Substitute Parts

Part Overview

The D4GL-2FFG-A4 is an interlock solenoid locking switch manufactured by Omron Automation and Safety. This component features a 3PST circuit configuration (2NC/1NO + DPST-NC) with a 24VDC supply voltage and 240VAC current rating of 750mA. The device provides a holding force of 102kgf and includes a status indicator for operational verification. The D4GL-2FFG-A4 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing maintenance applications. Suitable alternatives from the active D4SL-N series are available to maintain functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2FFG-A4 is based on the following critical parameters that must remain consistent across equivalent parts:

• Circuit Configuration: 3PST-2NC/1NO + DPST-NC topology must be maintained
• Voltage Supply: 24VDC supply requirement
• Actuator Type: Panel Disconnect functionality
• Termination Style: Screw Terminal connection method
• Conduit Thread Size: G1/2 thread specification
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67 rating for dust and water resistance
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The D4SL-N series from Omron provides active alternatives that maintain these core functional and mechanical parameters. Differences in current rating, voltage rating, and holding force are acceptable variations within the solenoid locking switch category, provided the application requirements do not exceed the substitute part specifications.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2FFG-D4N is the primary substitute for the D4GL-2FFG-A4. This part maintains the 102kgf holding force specification of the original component, ensuring equivalent mechanical performance in panel disconnect applications. The D4SL-N2FFG-D4N is in active production status with full compliance to CCC, CE, cURus, and TUV certifications, providing long-term availability and regulatory support.

D4SL-N2FFG-D4 serves as an alternative substitute when holding force requirements are less critical. This variant provides reduced holding force (6kgf) but maintains all other functional and mechanical parameters. The D4SL-N2FFG-D4 is also in active production with equivalent certifications and is suitable for applications where lower clamping force is acceptable.

Both D4SL-N series alternatives provide superior current handling capability (1.5A AC) compared to the original D4GL-2FFG-A4 (750mA AC), offering enhanced performance margins in AC switching applications. The transition from the obsolete D4GL series to the active D4SL-N series ensures continued component availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2FFG-D4 and D4SL-N2FFG-D4N be used interchangeably with D4GL-2FFG-A4?

A: Both D4SL-N variants maintain the same circuit configuration (3PST-2NC/1NO + DPST-NC), voltage supply (24VDC), actuator type (Panel Disconnect), termination style (Screw Terminal), and environmental ratings (IP67, -10°C ~ 55°C). Selection between them depends on holding force requirements. D4SL-N2FFG-D4N matches the original 102kgf specification, while D4SL-N2FFG-D4 provides 6kgf.

Q: What are the key differences in electrical performance between the substitute parts?

A: The D4GL-2FFG-A4 is rated for 750mA at 240VAC. The D4SL-N series parts are rated for 1.5A at 120VAC and 220mA at 125VDC. Applications operating at 240VAC should verify that the substitute part's 120VAC rating is appropriate for the intended circuit voltage.

Q: Are the substitute parts available in the same packaging as the original?

A: The D4GL-2FFG-A4 was supplied in standard packaging. The D4SL-N2FFG-D4 and D4SL-N2FFG-D4N are available in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N variants carry CCC, CE, cURus, and TUV certifications. The original D4GL-2FFG-A4 carried CE, cULus, and TUV certifications. The D4SL-N series provides expanded regulatory coverage suitable for global applications.

Q: Is the G1/2 conduit thread size maintained across all parts?

A: Yes. The D4GL-2FFG-A4, D4SL-N2FFG-D4, and D4SL-N2FFG-D4N all feature G1/2 conduit thread size, ensuring mechanical compatibility in existing panel installations.
