Key Parameters

Substitute Part Grouping Explanation

Substitution for the ASD2122N is based on the following critical parameters that must remain consistent:

• Functional Classification: Selector switch with two-position capability
• Manufacturer Consistency: IDEC manufacture ensures design and performance alignment
• Compliance Standards: ROHS3 compliance and EAR99 export classification
• Moisture Sensitivity: MSL 1 rating for unlimited environmental exposure tolerance
• Tariff Classification: HTSUS code 8536.50.9025 for regulatory and procurement purposes

The ASD2122NU qualifies as a direct substitute based on matching all critical parameters while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The ASD2122NU is the direct equivalent for the obsolete ASD2122N. Both parts share identical compliance certifications (ROHS3), moisture sensitivity ratings (MSL 1), and export classifications (EAR99). The primary distinction is product status: ASD2122NU maintains active manufacturing status, ensuring continued availability and supply chain reliability. Selection of ASD2122NU eliminates obsolescence risk while preserving all electrical and mechanical compatibility parameters specified for the original ASD2122N application.
