Substitute Part Grouping Explanation

The D4SL-4KDG-DN has one identified substitute: D4SL-N4FFG-DN. This substitution is based on the following criteria:

• Both components are manufactured by Omron Automation and Safety
• Both belong to the D4SL product family, indicating mechanical and electrical compatibility within the series
• The substitute part (D4SL-N4FFG-DN) is currently in active production status, providing long-term availability
• Both components share MSL Level 1 (Unlimited) moisture sensitivity classification
• The substitute maintains equivalent environmental protection and operational reliability standards

The D4SL-N4FFG-DN is an interlock solenoid locking switch with enhanced functionality compared to the original snap action design, offering additional circuit configurations and control capabilities.

Parameter Comparison

Engineering Selection Recommendations

Selection between the D4SL-4KDG-DN and D4SL-N4FFG-DN should be based on the following factors:

• Product Status Consideration: The D4SL-4KDG-DN is obsolete. For new designs or long-term production requirements, the D4SL-N4FFG-DN is the appropriate choice due to its active production status and guaranteed future availability.

• Compliance and Certification: The D4SL-N4FFG-DN carries multiple international certifications (CCC, CE, cURus, TUV), making it suitable for applications requiring regulatory compliance across multiple markets.

• Inventory Availability: Both components are currently in stock. The D4SL-4KDG-DN may be used for legacy system repairs where exact part matching is required, while the D4SL-N4FFG-DN is recommended for new implementations.

• Export Classification: The D4SL-N4FFG-DN is classified as EAR99, providing clearer export compliance documentation compared to the obsolete classification of the original part.
