Key Parameters

Substitute Part Grouping Explanation

The AOFD401NUB qualifies as a direct substitute based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by IDEC
• Product Category: Both are pushbutton switches
• Physical Form Factor: Both utilize 30MM construction
• Electrical Contact Configuration: Both feature 1NC (one normally closed) contact arrangement
• RoHS Compliance: Both meet ROHS3 Compliant standards
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• Trade Classification: Both share identical ECCN (EAR99) and HTSUS (8536.50.9035) codes

The AOFD401NUB represents an active product variant within the same AOFD401 base product family, providing functional equivalence for the obsolete AOFD401N-B.

Parameter Comparison

Engineering Selection Recommendations

The AOFD401NUB is the appropriate substitute for the obsolete AOFD401N-B based on product status and regulatory compliance alignment. The substitute part maintains active manufacturing status through IDEC, ensuring supply chain availability. Both components satisfy ROHS3 Compliant requirements and share identical trade classification codes, supporting direct substitution in applications requiring regulatory documentation and compliance verification. The active status of AOFD401NUB provides long-term component availability compared to the obsolete AOFD401N-B.

Frequently Asked Questions (FAQ)

Q: Can AOFD401NUB directly replace AOFD401N-B in existing applications?

A: Yes. Both components share the same manufacturer (IDEC), base product family (AOFD401), contact configuration (1NC), physical form factor (30MM), and regulatory compliance status (ROHS3). The AOFD401NUB is classified as active, whereas AOFD401N-B is obsolete.

Q: What is the significance of the packaging difference between these parts?

A: AOFD401N-B packaging is listed as "-" (unspecified), while AOFD401NUB is supplied in Bulk packaging. This difference reflects the active versus obsolete status and does not affect functional compatibility in component selection.

Q: Are there compliance considerations when substituting these parts?

A: Both parts maintain identical ROHS3 Compliant status, ECCN (EAR99), and HTSUS (8536.50.9035) classifications. No compliance adjustments are required when substituting AOFD401NUB for AOFD401N-B.

Q: Why is AOFD401N-B listed as obsolete?

A: Product obsolescence reflects manufacturing discontinuation by IDEC. The AOFD401NUB, as an active variant within the same AOFD401 base product family, provides functional continuity for applications originally specified with AOFD401N-B.
