Substitute Part Grouping Explanation

The AOFD401NUS is identified as a direct substitute for the AOFD401N-S based on the following criteria:

• Manufacturer Consistency: Both parts are manufactured by IDEC, ensuring design and quality standards alignment
• Functional Classification: Both are classified as pushbutton switches with 30MM form factor
• Regulatory Compliance: Both maintain ROHS3 compliance and identical ECCN and HTSUS classifications
• Moisture Sensitivity: Both share MSL rating of 1 (Unlimited), indicating identical environmental handling requirements
• Base Product Number: The AOFD401NUS shares the common base product number AOFD401 with the main part, confirming functional equivalence

The primary distinction is product status: AOFD401N-S is obsolete while AOFD401NUS is active, making the latter the appropriate selection for new applications and ongoing component availability.

Parameter Comparison

Engineering Selection Recommendations

Selection between AOFD401N-S and AOFD401NUS should be based on the following factors:

For New Designs and Active Systems: AOFD401NUS is the appropriate choice due to its active product status, ensuring long-term availability, manufacturer support, and continued compliance certification.

For Legacy System Maintenance: AOFD401N-S may be retained in existing installations where component replacement is not required. However, for any new procurement or system upgrades, transition to AOFD401NUS is recommended to maintain supply chain continuity.

Compliance Considerations: Both parts maintain identical ROHS3 compliance and regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9035), ensuring no compliance barriers to substitution.

Environmental Handling: The identical MSL rating of 1 (Unlimited) confirms that both parts share identical moisture sensitivity and storage requirements, eliminating environmental compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can AOFD401NUS directly replace AOFD401N-S in existing installations? A: Yes. Both parts share identical functional classification, regulatory compliance, and environmental ratings. The AOFD401NUS is the active equivalent of the obsolete AOFD401N-S.

Q: What is the significance of the base product number AOFD401? A: The shared base product number AOFD401 indicates that both AOFD401N-S and AOFD401NUS are variants of the same core product line, confirming functional equivalence and design compatibility.

Q: Are there packaging differences between these parts? A: The AOFD401N-S packaging is unspecified, while AOFD401NUS is supplied in bulk packaging. Packaging differences do not affect functional compatibility; they relate only to order quantity and handling logistics.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both parts are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8536.50.9035) classifications, confirming equivalent regulatory status.

Q: Why is AOFD401N-S listed as obsolete? A: Obsolescence indicates the manufacturer has discontinued active production and support. AOFD401NUS represents the current active equivalent, ensuring ongoing availability and manufacturer backing.
