Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASD3140N is determined by the following parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Functional Classification: Selector Switch Position (same functional category)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental handling compatibility)
• ECCN Classification: EAR99 (export control consistency)
• HTSUS Code: 8536.50.9025 (tariff classification alignment)

The substitute part ASD3140NU shares all critical parameters with the main part, with the distinction that ASD3140NU maintains active product status and is available in bulk packaging, making it the direct functional equivalent for the obsolete ASD3140N.

Parameter Comparison

Engineering Selection Recommendations

The ASD3140NU is the direct substitute for the obsolete ASD3140N. Both parts are manufactured by IDEC and maintain identical compliance certifications (ROHS3 Compliant), regulatory classifications (EAR99, HTSUS 8536.50.9025), and environmental handling requirements (MSL 1 - Unlimited). The primary distinction is product status: ASD3140NU is actively manufactured and available in bulk packaging, whereas ASD3140N is obsolete. For new designs and ongoing production requirements, ASD3140NU should be specified. Existing inventory of ASD3140N may be utilized for legacy system maintenance where component availability permits.

Frequently Asked Questions (FAQ)

Q: Can ASD3140NU directly replace ASD3140N in existing applications?

A: Yes. Both parts are IDEC selector switches with identical functional classification, RoHS compliance status, and environmental specifications. The ASD3140NU is the active production equivalent of the obsolete ASD3140N.

Q: What is the difference between ASD3140N and ASD3140NU packaging?

A: ASD3140N is supplied in standard packaging, while ASD3140NU is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement and inventory management requirements.

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

A: No. Both parts share identical RoHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8536.50.9025), ensuring regulatory equivalence for all applications.

Q: Why is ASD3140N listed as obsolete?

A: ASD3140N has been discontinued by IDEC. The ASD3140NU represents the current active production part and should be specified for all new designs and future procurement.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly. This classification ensures compatibility with standard manufacturing and storage environments without special precautions.
