Substitute Part Grouping Explanation

Substitution of the ASD31L40N is based on the following critical parameters:

• Manufacturer Alignment: IDEC as the original manufacturer
• Base Product Series: ASD31 series designation
• Functional Classification: 3-position selector switch
• Compliance Requirements: ROHS3 compliance and EAR99 export classification
• Moisture Sensitivity: MSL 1 (Unlimited) rating
• Tariff Classification: HTSUS 8536.50.9025

The substitute part ASD31L40NU shares the identical base product number (ASD31), maintains equivalent compliance certifications, and preserves the same functional classification as a 3-position selector switch.

Parameter Comparison

Engineering Selection Recommendations

The ASD31L40NU serves as the direct substitute for the obsolete ASD31L40N. Both parts maintain identical compliance certifications (ROHS3, EAR99) and equivalent moisture sensitivity ratings. The primary distinction is product status: ASD31L40NU is currently active in production, ensuring availability for procurement and supply chain continuity. The packaging difference (bulk for ASD31L40NU versus standard for ASD31L40N) reflects current manufacturing and distribution practices for the active variant.

Frequently Asked Questions (FAQ)

Q: Can ASD31L40NU directly replace ASD31L40N in existing applications?

A: Yes. Both parts share the ASD31 base product number, identical functional classification as 3-position selector switches, and equivalent compliance certifications. The substitution is based on matching electrical and mechanical parameters within the IDEC ASD31 product family.

Q: What is the significance of the product status difference?

A: ASD31L40N is obsolete and no longer manufactured. ASD31L40NU is the active production equivalent, ensuring long-term availability and supply chain reliability for new designs and maintenance applications.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts maintain ROHS3 compliance, EAR99 export classification, and MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent for regulatory and environmental compliance purposes.

Q: Does packaging affect functional compatibility?

A: No. The packaging difference (standard versus bulk) reflects distribution methods only and does not impact electrical or mechanical performance. Component functionality remains identical.

Q: What parameters define substitution eligibility for ASD31 selector switches?

A: Substitution is determined by: manufacturer (IDEC), base product series (ASD31), functional type (3-position selector switch), compliance certifications (ROHS3, EAR99), and moisture sensitivity rating (MSL 1). All these parameters must align for direct substitution.
