Substitute Part Grouping Explanation

The D4SL-3PDA-D4 has one identified substitute within the Omron D4SL product family: the D4SL-N3PFA-D4. This substitution is based on the following criteria:

• Both parts belong to the D4SL series manufactured by Omron Automation and Safety
• The substitute part (D4SL-N3PFA-D4) maintains the same moisture sensitivity level (MSL 1 - Unlimited)
• The substitute is classified as active product status, ensuring ongoing availability and support
• Both components share compatible packaging and termination approaches suitable for industrial switching applications

The D4SL-N3PFA-D4 represents the current generation equivalent within the D4SL product line, designed to replace the obsolete D4SL-3PDA-D4 in active applications.

Parameter Comparison

Engineering Selection Recommendations

The D4SL-N3PFA-D4 is the designated substitute for the obsolete D4SL-3PDA-D4. Selection of this active component is based on:

• Active product status ensuring long-term availability and manufacturer support
• RoHS compliance certification, meeting current environmental and regulatory requirements
• Multiple approval certifications (CCC, CE, cURus, TUV) confirming compliance with international standards
• IP67 ingress protection rating providing enhanced environmental sealing
• Defined operating temperature range (-10°C ~ 55°C) suitable for industrial applications
• EAR99 export classification enabling broader distribution channels compared to the obsolete designation

The D4SL-N3PFA-D4 is the current production equivalent within the D4SL family and should be specified for all new designs and replacement applications.
