Key Parameters

Substitute Part Grouping Explanation

The ASD3120NU qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical manufacturer (IDEC)
• Matching functional classification (selector switch, three-position)
• Equivalent RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Matching tariff classification (HTSUS 8536.50.9025)
• Identical export control classification (ECCN EAR99)

The primary distinction is product status: ASD3120NU is active production, whereas ASD3120N is obsolete. The ASD3120NU shares the same base product number (ASD3120), confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The ASD3120NU is the direct equivalent for ASD3120N applications. Selection is based on:

• Active production status of ASD3120NU ensures supply chain continuity
• Maintained ROHS3 compliance across both parts
• Identical environmental and regulatory classifications
• Functional equivalence confirmed through shared base product number

For new designs or replacement stock, ASD3120NU is the appropriate selection. Packaging differences (standard versus bulk) do not affect functional compatibility and reflect only distribution format.

Frequently Asked Questions (FAQ)

Q: Can ASD3120NU directly replace ASD3120N in existing applications? A: Yes. Both parts share identical functional specifications, compliance certifications, and environmental ratings. The substitution is direct.

Q: Why is ASD3120N listed as obsolete? A: Product obsolescence reflects manufacturer discontinuation. ASD3120NU represents the active production equivalent.

Q: Does packaging format affect compatibility? A: No. Packaging differences (standard versus bulk) relate only to distribution and storage. Functional and electrical characteristics remain identical.

Q: Are there compliance concerns with substitution? A: No. Both parts maintain ROHS3 compliance and identical export control classifications (EAR99).

Q: What is the significance of the shared base product number? A: The base product number ASD3120 confirms that both ASD3120N and ASD3120NU are variants of the same core design, ensuring functional equivalence.
