Substitute Part Grouping Explanation

Substitution eligibility for the AOFD220N-B is determined by the following parameters:

• Manufacturer: IDEC (same manufacturer ensures design continuity)
• Form Factor: 30mm pushbutton switch configuration
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance match)
• Functional Classification: Pushbutton Switch (identical functional category)

The substitute part AOFD220NUB shares all critical parameters with the main part, differing only in product status (Active vs. Obsolete) and packaging configuration (Bulk vs. standard packaging). This substitution maintains full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AOFD220NUB is the direct substitute for the obsolete AOFD220N-B. Both components share identical base product lineage (AOFD220), regulatory compliance certifications, and environmental ratings. The AOFD220NUB maintains Active product status, ensuring continued availability and supply chain reliability. Selection of the AOFD220NUB eliminates obsolescence risk while preserving full compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can AOFD220NUB directly replace AOFD220N-B in existing applications?

A: Yes. Both components share identical RoHS compliance, moisture sensitivity ratings, and functional classification as 30mm pushbutton switches. The base product number (AOFD220) is common to both parts, confirming design compatibility.

Q: What is the primary difference between these two part numbers?

A: The AOFD220N-B is obsolete, while AOFD220NUB maintains Active product status. Packaging differs (standard vs. Bulk), but electrical and mechanical specifications remain equivalent.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, meeting all regulatory requirements for equivalent substitution.

Q: Why should I transition from AOFD220N-B to AOFD220NUB?

A: The AOFD220N-B is obsolete, creating supply and long-term availability risks. The AOFD220NUB provides identical functionality with assured ongoing availability and support.
