Key Parameters

Substitute Part Grouping Explanation

The D4SL-N4GFG-D4 qualifies as a substitute based on the following criteria:

Shared Classification Parameters:

• Manufacturer: Omron Automation and Safety (same manufacturer ensures design compatibility)
• Base Series: D4SL (both parts belong to the D4SL product family)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)
• Packaging Compatibility: Bulk packaging suitable for component-level replacement

Substitution Logic: The D4SL-N4GFG-D4 represents an active product variant within the same D4SL series family. As an interlock solenoid locking switch with 3PST circuit configuration, it provides equivalent switching functionality with enhanced features including status indication and higher environmental protection (IP67 rating). The part maintains the same MSL classification and manufacturer origin, supporting direct substitution in applications requiring snap action switching capability.

Engineering Selection Recommendations

Primary Substitute: D4SL-N4GFG-D4

Selection of the D4SL-N4GFG-D4 as the primary substitute is based on:

• Product Status Alignment: The substitute maintains active product status, ensuring long-term availability and continued manufacturer support, addressing the obsolescence of the original D4SL-4LDG-D4.
• Series Continuity: Both components belong to the Omron D4SL product family, maintaining design and integration consistency.
• Compliance Certifications: The D4SL-N4GFG-D4 carries multiple international approvals (CCC, CE, cURus, TUV) and RoHS compliance, meeting modern regulatory requirements.
• Environmental Rating: Identical MSL Level 1 classification ensures equivalent moisture handling and storage requirements.
• Manufacturer Consistency: Single-source manufacturer (Omron Automation and Safety) eliminates cross-manufacturer compatibility variables.

Frequently Asked Questions (FAQ)

Q: Why is the D4SL-4LDG-D4 being discontinued? A: The D4SL-4LDG-D4 has reached obsolete product status. Omron has transitioned this component to end-of-life, making the D4SL-N4GFG-D4 the recommended active alternative within the D4SL series.

Q: What are the key compatibility factors between D4SL-4LDG-D4 and D4SL-N4GFG-D4? A: Both components share the same manufacturer (Omron Automation and Safety), base product series (D4SL), and moisture sensitivity classification (MSL Level 1). These parameters establish functional equivalence for switching applications.

Q: Does the D4SL-N4GFG-D4 require different packaging or handling? A: The D4SL-N4GFG-D4 is supplied in Bulk packaging. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity, requiring identical storage and handling protocols.

Q: What additional features does the D4SL-N4GFG-D4 provide? A: The D4SL-N4GFG-D4 includes a status indicator, IP67 ingress protection rating, and multiple international certifications (CCC, CE, cURus, TUV). These enhancements provide improved environmental protection and regulatory compliance compared to the obsolete predecessor.

Q: Are there electrical specification differences between these parts? A: The D4SL-N4GFG-D4 specifies 3PST-NC + DPST-NO/NC circuit configuration with 1.5A AC and 220mA DC current ratings at 120VAC/125VDC. Original D4SL-4LDG-D4 electrical specifications were not provided in available documentation.

Q: Is the D4SL-N4GFG-D4 RoHS compliant? A: Yes, the D4SL-N4GFG-D4 is RoHS compliant. Original D4SL-4LDG-D4 RoHS status was not specified in available documentation.
