• Identical RoHS3 compliance status
• Identical MSL rating (1 - Unlimited)
• Identical ECCN classification (EAR99)
• Identical HTSUS code (8536.50.9035)

The AYD301NUS represents an active product variant within the same product family, providing functional continuity for applications previously served by the obsolete AYD301N-S.

Parameter Comparison

Engineering Selection Recommendations

The AYD301NUS is the appropriate substitute for the obsolete AYD301N-S. Selection is based on:

• Product Status Alignment: The AYD301NUS maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and export classification (EAR99), satisfying regulatory requirements without modification.
• Environmental Specifications: Matching MSL ratings (1 - Unlimited) confirm equivalent environmental performance characteristics.
• Tariff Classification: Identical HTSUS codes confirm equivalent commodity classification for procurement and customs purposes.

Frequently Asked Questions (FAQ)

Q: Can the AYD301NUS directly replace the AYD301N-S in existing applications?

A: Yes. Both parts share identical compliance certifications (ROHS3), environmental ratings (MSL 1), and regulatory classifications (EAR99, HTSUS 8536.50.9035). The AYD301NUS is manufactured by the same supplier (IDEC) within the same product family.

Q: What is the primary difference between these parts?

A: The AYD301N-S is obsolete, while the AYD301NUS is an active product. The AYD301NUS includes specification details indicating a push-pull mechanism with 1NC (one normally closed) contact configuration and blue color designation.

Q: Are there packaging differences between these parts?

A: The AYD301N-S is specified with dash packaging notation, while the AYD301NUS is supplied in bulk packaging. Packaging format does not affect functional compatibility.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity), and are classified under ECCN EAR99 with HTSUS code 8536.50.9035.
