Substitute Part Grouping Explanation

The D4SL-3NDA-DN has one identified substitute: D4SL-N3NFA-DN. This substitution is based on the following criteria:

• Both components belong to the D4SL series manufactured by Omron Automation and Safety
• The substitute part (D4SL-N3NFA-DN) maintains the same base product number (D4SL), ensuring mechanical and electrical compatibility within the series
• The substitute is classified as Active product status, providing continued availability and manufacturer support
• Both parts share MSL classification of 1 (Unlimited), indicating identical moisture sensitivity requirements
• The substitute part carries full regulatory compliance (REACH Unaffected, EAR99 classification) compared to the obsolete part's undefined status

Parameter Comparison

Engineering Selection Recommendations

Selection between the D4SL-3NDA-DN and D4SL-N3NFA-DN should be based on the following factors:

• Product Status Consideration: The D4SL-N3NFA-DN is the recommended choice for new designs and long-term applications due to its Active product status. The D4SL-3NDA-DN should be reserved for legacy system maintenance where existing inventory is available.

• Regulatory Compliance: The D4SL-N3NFA-DN provides defined REACH compliance status (REACH Unaffected) and standard ECCN classification (EAR99), whereas the D4SL-3NDA-DN carries undefined REACH status and obsolete ECCN designation. This distinction is critical for applications subject to regulatory oversight.

• Supply Chain Continuity: Both parts maintain current inventory levels. However, the Active status of D4SL-N3NFA-DN ensures continued manufacturer support and future availability, whereas D4SL-3NDA-DN availability is limited to existing stock.

• Series Compatibility: Both components share the D4SL base product number, confirming mechanical and electrical compatibility within the D4SL switch family.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N3NFA-DN directly replace D4SL-3NDA-DN in existing applications?

A: Yes. Both components share the D4SL base product number and identical MSL classification, confirming compatibility within the D4SL series. The substitute maintains the same mechanical interface and environmental specifications.

Q: What is the primary reason for substitution?

A: The D4SL-3NDA-DN is classified as obsolete. The D4SL-N3NFA-DN is the active equivalent within the D4SL series, providing continued manufacturer support and defined regulatory compliance.

Q: Are there differences in packaging between these parts?

A: Both parts are supplied in Bulk packaging, eliminating packaging-related compatibility concerns.

Q: How does REACH compliance affect part selection?

A: The D4SL-N3NFA-DN carries REACH Unaffected status with standard EAR99 classification, providing clear regulatory standing. The D4SL-3NDA-DN has undefined REACH status and obsolete ECCN designation. For applications requiring regulatory documentation, D4SL-N3NFA-DN is the appropriate choice.

Q: Is inventory availability a factor in part selection?

A: Both parts maintain adequate inventory (1042 pcs and 1062 pcs respectively). However, D4SL-3NDA-DN inventory is finite due to obsolete status, while D4SL-N3NFA-DN benefits from active production and continued availability.
