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

Part Overview

The Omron D4GL-2EFA-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 identification of active equivalent parts essential for system maintenance and new installations. The D4GL series has been superseded by the D4SL-N series, which maintains functional compatibility while offering enhanced electrical ratings and active product support.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-2EFA-A4 can be substituted with active D4SL-N series components based on the following criteria:

Functional Equivalence Parameters:

• Identical circuit configuration: 3PST-2NC/1NO + DPST-NO/NC
• Identical actuator type: Panel Disconnect
• Identical termination style: Screw Terminal
• Identical conduit thread size: G1/2
• Identical operating temperature range: -10°C to 55°C
• Identical ingress protection rating: IP67

Enhanced Electrical Ratings: The D4SL-N series provides higher current capacity (1.5A AC, 220mA DC) and broader voltage compatibility (120VAC/125VDC) compared to the D4GL-2EFA-A4 (750mA AC, 240VAC). This increased rating capability ensures the substitute parts can handle the original application requirements while supporting additional load scenarios.

Mechanical Compatibility: Both series maintain identical mechanical interfaces, mounting configurations, and environmental protection standards, enabling direct functional replacement in existing installations.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The D4GL-2EFA-A4 is obsolete and no longer manufactured. The D4SL-N2EFA-D4 and D4SL-N2EFA-D4N are active products from the same manufacturer that provide direct functional substitution with enhanced electrical performance.

Compliance Considerations: Both substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part (CE, cULus, TUV), ensuring broader market compliance. The D4SL-N2EFA-D4N includes explicit ECCN classification (EAR99) and HTSUS code documentation, supporting international procurement and regulatory documentation requirements.

Electrical Performance: The D4SL-N series offers higher current capacity (1.5A AC versus 750mA AC) and DC current capability (220mA), providing margin above the original specification. The substitute parts support both 120VAC and 125VDC load voltages, extending application flexibility beyond the original 240VAC rating.

Mechanical and Environmental Compatibility: Both substitute parts maintain identical mechanical interfaces, mounting configurations, environmental protection (IP67), and operating temperature ranges, enabling direct installation without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2EFA-D4 and D4SL-N2EFA-D4N be used interchangeably? A: Yes. Both parts share identical electrical ratings, circuit configurations, mechanical interfaces, and environmental specifications. The primary difference is packaging format (both listed as Bulk) and the D4SL-N2EFA-D4N includes explicit ECCN and HTSUS documentation.

Q: What is the key difference between the D4GL-2EFA-A4 and D4SL-N substitutes? A: The D4SL-N series provides higher current capacity (1.5A AC versus 750mA AC), increased holding force (133kgf versus 102kgf), and broader voltage compatibility (120VAC/125VDC). Both maintain identical circuit configuration, mechanical form factor, and environmental protection.

Q: Are the substitute parts compatible with 24VDC supply voltage? A: The substitute parts maintain the same solenoid release function and panel disconnect actuator type as the original. Specific supply voltage compatibility should be confirmed through the complete technical datasheet, as this parameter was not provided in the substitute part specifications.

Q: Do the substitute parts require any installation modifications? A: No. The D4SL-N2EFA-D4 and D4SL-N2EFA-D4N maintain identical screw terminal connections, G1/2 conduit thread size, and mechanical mounting interfaces, enabling direct replacement without installation changes.

Q: What certifications do the substitute parts carry? A: Both D4SL-N substitutes carry CCC, CE, cURus, and TUV approvals, providing expanded regulatory coverage compared to the original D4GL-2EFA-A4 (CE, cULus, TUV).
