Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AOFD211N-B are identified based on the following critical parameters that determine functional and mechanical compatibility:

• 30mm form factor and physical dimensions
• Pushbutton switch functionality
• ROHS3 compliance certification
• Moisture Sensitivity Level 1 (Unlimited)
• Identical ECCN and HTSUS classification
• Manufacturer continuity (IDEC product line)

The AOFD211NUB qualifies as a direct substitute based on these parameters. Both parts share the same base product number (AOFD211), identical electrical and environmental compliance ratings, and equivalent packaging specifications for industrial control applications.

Parameter Comparison

Engineering Selection Recommendations

The AOFD211NUB is the qualified substitute for the obsolete AOFD211N-B. Selection is based on:

• Identical base product number (AOFD211) confirming mechanical and functional equivalence
• Active product status of the substitute, ensuring ongoing availability and supply chain continuity
• Matching ROHS3 compliance certification for regulatory and environmental requirements
• Equivalent MSL rating (1 - Unlimited) confirming identical moisture and environmental handling specifications
• Identical ECCN and HTSUS classifications, ensuring no changes to export control or tariff categorization

The substitute part maintains full compliance with the original part's electrical and mechanical specifications while providing access to current inventory and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Why is the AOFD211N-B listed as obsolete? A: The AOFD211N-B has been discontinued by IDEC. The AOFD211NUB serves as the active replacement within the same product family.

Q: Are the AOFD211N-B and AOFD211NUB mechanically interchangeable? A: Yes. Both parts share the same base product number (AOFD211) and identical 30mm form factor, confirming mechanical compatibility in applications designed for the original part.

Q: What is the significance of the matching ROHS3 compliance? A: ROHS3 compliance indicates both parts meet the same environmental and hazardous substance restrictions, ensuring regulatory equivalence for industrial and commercial applications.

Q: Does the MSL rating affect substitution? A: No. Both parts carry MSL 1 (Unlimited), indicating identical moisture sensitivity and storage requirements. No special handling changes are required when substituting.

Q: Is packaging a factor in selecting the substitute? A: Packaging format (Bulk for AOFD211NUB) does not affect functional or mechanical compatibility. Packaging selection depends on procurement and inventory management requirements.

Q: Are there any export or tariff implications when using the substitute? A: No. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9035) classifications, ensuring no changes to export control or tariff treatment.
