D4SL-4KDG-D4N Equivalent & Substitute Parts

Part Overview

The D4SL-4KDG-D4N is an Omron Automation and Safety snap action switch classified as obsolete. As an obsolete product, sourcing original inventory becomes increasingly difficult, necessitating identification of functionally equivalent substitute components. The D4SL-4KDG-D4N remains available in limited stock (897 Pcs), but long-term availability cannot be assured. Substitute parts must maintain compatibility with the original electrical and mechanical specifications to ensure system reliability.

Series Relationship: The D4SL-N4FFG-D4N belongs to the D4SL series, the same base product family as the original part, indicating shared mechanical and electrical architecture.

Moisture Sensitivity Level: Both parts maintain MSL 1 (Unlimited), confirming equivalent environmental tolerance and storage requirements.

Regulatory Compliance: The substitute part carries active certifications (CCC, CE, cURus, TUV) and is classified as EAR99, providing current compliance documentation versus the obsolete status of the original.

Product Status: The D4SL-N4FFG-D4N is Active, ensuring ongoing availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The D4SL-N4FFG-D4N is the designated substitute for the D4SL-4KDG-D4N. The substitute part is currently Active with manufacturer support and carries current regulatory certifications (CCC, CE, cURus, TUV), whereas the original part is Obsolete with undefined REACH status.

Compliance Consideration: The substitute part is classified as EAR99, providing clear export control documentation. The original part is marked OBSOLETE in ECCN classification, indicating it no longer receives regulatory updates.

Inventory Planning: While both parts are currently in stock, the substitute part (D4SL-N4FFG-D4N) with 642 Pcs available represents the sustainable long-term sourcing option. The original part inventory of 897 Pcs should be considered finite.

Mechanical and Electrical Compatibility: Both parts share the D4SL base product family designation from Omron, indicating mechanical mounting compatibility and electrical interface consistency within the series.

Frequently Asked Questions (FAQ)

Q: Why is the D4SL-4KDG-D4N marked as obsolete? A: The D4SL-4KDG-D4N has reached end-of-life status with Omron Automation and Safety. Obsolete classification indicates the manufacturer no longer produces this specific model and will not provide technical updates or regulatory support.

Q: Is the D4SL-N4FFG-D4N a direct pin-for-pin replacement? A: Both parts belong to the D4SL series from Omron. The D4SL-N4FFG-D4N features a Connector termination style and Panel Disconnect actuator type. Mechanical and electrical compatibility within the D4SL family is maintained, but installation requirements should be verified against your specific application documentation.

Q: What are the key electrical differences between these parts? A: The D4SL-N4FFG-D4N specifies a 3PST-2NC/1NO + DPST-NC circuit configuration with 1.5A AC and 220mA DC current ratings at 120VAC/125VDC. The original part specifications are not provided in available documentation. Electrical compatibility must be confirmed against your system requirements.

Q: Are both parts suitable for the same environmental conditions? A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity level. The D4SL-N4FFG-D4N provides IP67 ingress protection (Dust Tight, Waterproof) and operates across -10°C to 55°C. Environmental suitability depends on your specific application conditions.

Q: What certifications does the substitute part carry? A: The D4SL-N4FFG-D4N holds CCC, CE, cURus, and TUV approvals. The original part carries no specified approval agencies in available documentation.

Q: How should packaging be considered in the substitution? A: Both parts are supplied in Bulk packaging. No special packaging requirements differentiate these parts in standard procurement scenarios.
