Equivalent & Substitute Parts for D4GL-2EFA-A

Part Overview

The D4GL-2EFA-A is an interlock solenoid release manufactured by Omron Automation and Safety, configured as a 3PST switch with combined 2NC/1NO and DPST-NO/NC circuits. This component is designed for panel disconnect applications requiring a 24VDC supply with 240VAC rated switching capacity at 750mA. The product is currently obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued availability for maintenance and replacement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2EFA-A is determined by the following critical parameters:

• Circuit configuration (3PST-2NC/1NO + DPST-NO/NC)
• Actuator type (Panel Disconnect)
• Termination style (Screw Terminal)
• Conduit thread size (G1/2)
• Ingress protection rating (IP67)
• Operating temperature range (-10°C ~ 55°C)

The D4SL-N series components D4SL-N2EFA-D and D4SL-N2EFA-DN satisfy these core functional and mechanical requirements. Both substitute parts maintain identical circuit topology, actuator configuration, termination method, and environmental specifications. The D4SL-N series represents the active product line continuation from the obsolete D4GL series within the Omron interlock solenoid release portfolio.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N2EFA-D and D4SL-N2EFA-DN are active products from Omron Automation and Safety and represent the current generation equivalents to the obsolete D4GL-2EFA-A. Selection between these two substitute parts should be based on packaging requirements: D4SL-N2EFA-D is supplied in bulk packaging, while D4SL-N2EFA-DN is also supplied in bulk packaging.

The D4SL-N series components provide enhanced electrical performance characteristics compared to the D4GL-2EFA-A, including increased current rating (1.5A AC versus 750mA AC) and higher holding force (133kgf versus 102kgf). Both substitute parts maintain full compatibility with the mechanical and environmental specifications of the original component and carry expanded regulatory approvals including CCC certification in addition to CE, cURus, and TUV certifications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2EFA-D or D4SL-N2EFA-DN be used as direct replacements for D4GL-2EFA-A?

A: Yes. Both substitute parts maintain identical circuit topology (3PST-2NC/1NO + DPST-NO/NC), actuator type (Panel Disconnect), termination style (Screw Terminal), conduit thread size (G1/2), and environmental specifications (IP67, -10°C ~ 55°C operating range). The mechanical and functional interfaces are compatible.

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

A: The D4SL-N series provides higher current capacity (1.5A AC, 220mA DC) compared to the D4GL-2EFA-A (750mA AC). The D4SL-N series also operates at different voltage levels (120VAC, 125VDC) versus the original (24VDC supply, 240VAC rating). The holding force is increased from 102kgf to 133kgf. These enhancements represent improvements in the product line.

Q: Are there packaging differences between D4SL-N2EFA-D and D4SL-N2EFA-DN?

A: Both parts are supplied in bulk packaging. No functional or electrical differences exist between these two part numbers.

Q: What regulatory certifications apply to the substitute parts?

A: D4SL-N2EFA-D and D4SL-N2EFA-DN carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-2EFA-A (CE, cULus, TUV).
