ASD2120N Equivalent & Substitute Parts

Part Overview

The ASD2120N is a selector switch manufactured by IDEC, classified as a two-position selector switch. This component is currently listed as obsolete, which necessitates identification of active equivalent parts for continued system support and procurement. The ASD2120N maintains ROHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial control applications.

Substitute Part Grouping Explanation

The ASD2120NU qualifies as a direct substitute for the ASD2120N based on the following alignment of critical parameters:

• Identical manufacturer (IDEC)
• Matching functional classification (selector switch, two-position)
• Equivalent RoHS compliance (ROHS3)
• Identical moisture sensitivity rating (MSL 1 - Unlimited)
• Matching ECCN and HTSUS classifications
• Shared base product number (ASD2120)

The primary distinction is product status: ASD2120NU is active and available, whereas ASD2120N is obsolete. The packaging difference (Bulk for ASD2120NU versus standard for ASD2120N) does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The ASD2120NU is the direct active equivalent for the obsolete ASD2120N. Both components share identical electrical and mechanical specifications, compliance certifications, and regulatory classifications. Selection of ASD2120NU is appropriate for new designs and replacement applications where the ASD2120N is no longer procurable. The active product status of ASD2120NU ensures continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can ASD2120NU directly replace ASD2120N in existing assemblies? A: Yes. Both parts share identical functional specifications, RoHS compliance, and moisture sensitivity ratings. The substitution is direct with no design modifications required.

Q: What is the significance of the packaging difference? A: ASD2120NU is supplied in bulk packaging, while ASD2120N used standard packaging. This affects order quantities and handling but does not impact component performance or compatibility.

Q: Why is ASD2120N listed as obsolete? A: Product obsolescence is determined by the manufacturer. ASD2120NU represents the active continuation of this product line and should be used for all new procurement.

Q: Are there any compliance differences between these parts? A: No. Both components maintain identical ROHS3 compliance, ECCN classification (EAR99), and HTSUS coding (8536.50.9025).

Q: Is the MSL rating the same for both parts? A: Yes. Both ASD2120N and ASD2120NU carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
