Substitute Part Grouping Explanation

The ASD3L04NU is classified as a direct manufacturer equivalent to the ASD3L04N based on the following substitution criteria:

• Functional Classification: Both parts are 3-position selector switches within the IDEC ASD3 series
• Regulatory Compliance: Identical RoHS3 compliance status
• Environmental Rating: Matching MSL 1 (Unlimited) moisture sensitivity level
• Trade Classification: Identical ECCN (EAR99) and HTSUS (8536.50.9025) codes
• Product Series: Both belong to the ASD3 base product family

The primary distinction is product status: ASD3L04N is obsolete while ASD3L04NU is active, making the latter the recommended current production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ASD3L04NU is the appropriate selection for applications currently using or specifying the ASD3L04N. Both parts maintain identical regulatory compliance (ROHS3) and environmental ratings (MSL 1). The transition from ASD3L04N to ASD3L04NU is supported by:

• Continued availability of the substitute part in active product status
• Maintained compliance certifications across both components
• Consistent trade classification and regulatory coding
• Membership in the same IDEC ASD3 product series

For new designs and ongoing procurement, ASD3L04NU is the designated equivalent.

Frequently Asked Questions (FAQ)

Q: Can ASD3L04NU directly replace ASD3L04N in existing applications?

A: Yes. Both parts share identical functional classification as 3-position selector switches, equivalent RoHS3 compliance, matching MSL ratings, and identical trade codes. The substitution is based on these aligned parameters.

Q: What is the primary reason for substitution?

A: ASD3L04N is classified as obsolete. ASD3L04NU is the active equivalent within the IDEC ASD3 series, ensuring continued availability and support.

Q: Are there packaging differences between these parts?

A: ASD3L04N packaging is listed as standard, while ASD3L04NU is supplied in Bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8536.50.9025) classifications, and share MSL 1 (Unlimited) ratings.

Q: Which part should be specified for new designs?

A: ASD3L04NU should be specified for new designs due to its active product status and continued manufacturer support within the ASD3 series.
