Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASD3122N is determined by the following parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Product Category: Selector Switch (functional equivalence)
• Functional Description: 3-position selector switch operation
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (environmental tolerance match)
• ECCN Classification: EAR99 (export control consistency)
• HTSUS Code: 8536.50.9025 (tariff classification alignment)

The ASD3122NU qualifies as a direct substitute based on matching all critical parameters while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The ASD3122NU is the direct substitute for the obsolete ASD3122N. Both components share identical electrical and mechanical parameters, regulatory compliance certifications, and environmental ratings. The ASD3122NU maintains active product status with IDEC, ensuring continued availability and supply chain stability. Both parts are ROHS3 compliant and carry MSL 1 classification, indicating no moisture sensitivity constraints during storage or handling. Selection of the ASD3122NU eliminates obsolescence risk while preserving full functional and compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the ASD3122NU directly replace the ASD3122N in existing designs?

A: Yes. Both parts share identical functional specifications, RoHS compliance status, moisture sensitivity ratings, and export classifications. The ASD3122NU is the active equivalent of the obsolete ASD3122N.

Q: What is the difference between ASD3122N and ASD3122NU?

A: The primary difference is product status. The ASD3122N is obsolete, while the ASD3122NU is active. Both are manufactured by IDEC and meet identical electrical, mechanical, and regulatory requirements. The packaging differs (ASD3122NU is supplied in bulk), but functional performance is equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ASD3122N and ASD3122NU are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8536.50.9025) classifications, and share MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why should I transition from ASD3122N to ASD3122NU?

A: The ASD3122N is obsolete and subject to inventory depletion. The ASD3122NU is the active IDEC equivalent, ensuring long-term availability and supply chain continuity for new production and maintenance applications.

Q: Is the ASD3122NU available in different packaging options?

A: The ASD3122NU is supplied in bulk packaging. Packaging specifications should be confirmed with your component supplier based on your procurement requirements.
