Substitute Part Grouping Explanation

The AYD301NUG qualifies as a direct substitute for the AYD301N-G based on the following alignment of critical parameters:

• Mechanical Compatibility: Both parts share the 30mm form factor standard for emergency stop pushbutton switches
• Manufacturer Consistency: Both are manufactured by IDEC, ensuring design and quality continuity
• Electrical Function: Both are configured as pushbutton switches with emergency stop functionality
• Regulatory Compliance: Both maintain ROHS3 compliance and identical ECCN/HTSUS classifications
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited), indicating equivalent environmental tolerance
• Base Product Series: The AYD301NUG shares the AYD301 base product number with the original part, confirming design lineage

The primary distinction is product status: AYD301N-G is obsolete while AYD301NUG is active, making the latter the current production equivalent.

Engineering Selection Recommendations

The AYD301NUG is the appropriate substitute for the obsolete AYD301N-G in applications requiring 30mm emergency stop pushbutton switch functionality. Selection is based on:

• Product Status Alignment: The substitute is in active production status, ensuring availability and ongoing manufacturer support
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and export classification codes, eliminating compliance risk in substitution
• Certification Continuity: Matching MSL, ECCN, and HTSUS classifications confirm that the substitute meets all regulatory and environmental requirements of the original specification
• Mechanical and Electrical Equivalence: Identical form factor, contact configuration, and push-pull operation ensure direct functional replacement without system redesign

Frequently Asked Questions (FAQ)

Q: Can AYD301NUG directly replace AYD301N-G in existing installations?

A: Yes. Both parts share identical mechanical form factors (30mm), electrical function (push-pull emergency stop), contact configuration (1NC), and regulatory compliance status. Direct substitution is supported by parameter equivalence.

Q: What is the significance of the product status change from Obsolete to Active?

A: The obsolete status of AYD301N-G indicates end-of-life for that specific part number. The AYD301NUG, as the active equivalent, represents the current production offering from IDEC for this functional category and is the recommended source for new procurement and replacement inventory.

Q: Are there packaging differences between these parts?

A: The AYD301N-G is listed with standard packaging, while AYD301NUG is supplied in Bulk packaging. Both configurations contain the same component; packaging selection depends on order quantity and inventory management requirements.

Q: Do both parts meet the same environmental and export requirements?

A: Yes. Both parts are ROHS3 compliant, rated MSL 1 (Unlimited moisture sensitivity), and classified under identical ECCN (EAR99) and HTSUS (8536.50.9035) codes. No additional compliance verification is required for substitution.

Q: Is the AYD301 base product number significant for compatibility?

A: Yes. The AYD301NUG shares the AYD301 base product number with the original part, confirming it belongs to the same product family and design generation. This alignment supports functional and mechanical compatibility.
