Substitute Part Grouping Explanation

The D4SL-N3HFG-D is identified as a substitute for the D4SL-3MDG-D based on manufacturer lineage and product family alignment within the Omron D4SL series. Both components share the same base product number (D4SL) and are manufactured by Omron Automation and Safety. The substitute part maintains compatibility through:

• Shared manufacturer ecosystem (Omron Automation and Safety)
• Common base product family (D4SL series)
• Equivalent moisture sensitivity classification (MSL 1 - Unlimited)
• Regulatory compliance framework (REACH and export control alignment)

Parameter Comparison

Engineering Selection Recommendations

The D4SL-N3HFG-D is an active production substitute for the obsolete D4SL-3MDG-D. Selection of the substitute part is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• Identical MSL classification (1 - Unlimited) confirming equivalent environmental handling requirements
• Comprehensive regulatory certifications (CCC, CE, cURus, TUV) providing broader compliance coverage than the original part
• Shared manufacturer and base product family ensuring design and integration consistency

The transition from the obsolete D4SL-3MDG-D to the D4SL-N3HFG-D is appropriate for new designs and component replacement scenarios where the original part specification is no longer obtainable.
