Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3L20N is based on the following critical parameters that must remain consistent:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Functional Classification: Selector Switch with 3-position capability
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (environmental tolerance match)
• ECCN/HTSUS Classification: EAR99 / 8536.50.9025 (trade classification consistency)

The substitute part ASD3L20NU meets all these criteria while maintaining active product status, making it a direct functional equivalent for the obsolete ASD3L20N.

Frequently Asked Questions (FAQ)

Q: Can ASD3L20NU be used as a direct replacement for ASD3L20N?

A: Yes. The ASD3L20NU is a direct substitute. Both parts share identical functional classification (3-position selector switch), RoHS compliance status, moisture sensitivity rating, and trade classifications. The primary difference is product status: ASD3L20NU is active while ASD3L20N is obsolete.

Q: What is the significance of the base product number ASD3?

A: The base product number ASD3 indicates both parts belong to the same product family within IDEC's selector switch line. This confirms design compatibility and functional equivalence.

Q: Are there packaging differences between these parts?

A: The ASD3L20N is listed with dash packaging notation, while ASD3L20NU specifies bulk packaging. Packaging differences do not affect electrical or mechanical compatibility; they reflect inventory and distribution methods.

Q: Why is the ASD3L20N listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The ASD3L20NU represents the active continuation of this product line and should be used for all new designs and replacements.

Q: Are the compliance certifications identical?

A: Yes. Both parts carry ROHS3 compliance, EAR99 ECCN classification, and 8536.50.9025 HTSUS code, confirming equivalent regulatory and trade status.
