Omron D4GL-2FFG-A Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2FFG-A is a 3PST interlock solenoid locking switch designed for panel disconnect applications with a 24VDC supply voltage and 240VAC current rating of 750mA. This component features a holding force of 102kgf, IP67 ingress protection, and screw terminal connectivity. The D4GL-2FFG-A is classified as obsolete, making identification of active equivalent parts essential for new designs and system maintenance. Substitute parts must maintain functional compatibility across circuit configuration, mechanical interface, and environmental specifications.

Substitute Part Grouping Explanation

Substitute parts for the D4GL-2FFG-A are identified from the D4SL-N series based on the following critical parameters:

Maintained Compatibility Criteria:

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

Parameter Differences in Substitutes: The D4SL-N2FFG-D and D4SL-N2FFG-DN provide enhanced electrical ratings compared to the obsolete D4GL-2FFG-A. Both substitute parts support dual voltage operation (120VAC/125VDC) with increased current capacity (1.5A AC, 220mA DC) and higher holding force (133kgf). These upgrades maintain backward compatibility while offering improved performance margins for new installations.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The D4GL-2FFG-A is obsolete and no longer manufactured. The D4SL-N2FFG-D and D4SL-N2FFG-DN are active production alternatives from Omron that maintain identical mechanical and circuit specifications while providing enhanced electrical performance.

Compliance Considerations: Both substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part (CE, cULus, TUV), supporting broader market deployment. The ECCN classification changes from OBSOLETE to EAR99, reflecting the active status of substitute components.

Performance Enhancement: Substitute parts deliver 30% higher holding force (133kgf vs. 102kgf) and doubled AC current capacity (1.5A vs. 750mA), providing improved operational margins without requiring design modifications to existing mechanical interfaces or terminal connections.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2FFG-D and D4SL-N2FFG-DN be used interchangeably as replacements for D4GL-2FFG-A? A: Yes. Both substitute parts maintain identical circuit configuration (3PST-2NC/1NO + DPST-NC), mechanical interface (Panel Disconnect, G1/2 conduit thread), termination style (Screw Terminal), and environmental specifications (IP67, -10°C ~ 55°C). The substitutes are direct functional equivalents with enhanced electrical ratings.

Q: What are the key differences between D4SL-N2FFG-D and D4SL-N2FFG-DN? A: Both parts share identical electrical specifications, mechanical design, and performance characteristics. The difference lies in packaging: D4SL-N2FFG-D is supplied in Bulk packaging, while D4SL-N2FFG-DN is also supplied in Bulk packaging. Selection between these variants depends on procurement and inventory requirements rather than technical compatibility.

Q: Are there voltage compatibility concerns when substituting the D4GL-2FFG-A? A: The original D4GL-2FFG-A operates at 24VDC supply with 240VAC current rating. Substitute parts D4SL-N2FFG-D and D4SL-N2FFG-DN support 120VAC and 125VDC ratings. System integration requires verification that the substitute part's voltage specifications align with the application's power supply configuration.

Q: Do the substitute parts maintain the same physical footprint and mounting interface? A: Yes. Both D4SL-N2FFG-D and D4SL-N2FFG-DN retain the Panel Disconnect actuator type, G1/2 conduit thread size, and Screw Terminal termination, ensuring compatibility with existing mechanical mounting and electrical connection infrastructure.

Q: What regulatory approvals apply to the substitute parts? A: D4SL-N2FFG-D and D4SL-N2FFG-DN carry CCC, CE, cURus, and TUV approvals, providing broader compliance coverage than the original D4GL-2FFG-A (CE, cULus, TUV). This expanded certification supports deployment in additional markets and regulatory jurisdictions.
