ASD320N Equivalent & Substitute Parts

Part Overview

The ASD320N is a selector switch manufactured by IDEC, classified as a 3-position DPST-NO (Double Pole Single Throw - Normally Open) switch rated for 10A AC at 110V and 8A DC at 24V. This component is designed for panel-mounted applications requiring manual position selection with screw terminal connections. The ASD320N is currently listed as obsolete, making identification of compatible substitute parts essential for maintenance, repair, and legacy system support.

Engineering Selection Recommendations

The ASD320NU is the designated substitute for the obsolete ASD320N. Selection is based on the following engineering criteria:

• Product Status Alignment: The ASD320NU maintains active product status with current manufacturing and inventory availability, eliminating supply chain risk associated with the obsolete ASD320N.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN/HTSUS classifications, ensuring regulatory equivalence for procurement and deployment.
• Manufacturer Continuity: Both parts share the same base product number (ASD320) and manufacturer (IDEC), indicating direct lineage and design compatibility.
• Electrical and Mechanical Specifications: The ASD320NU preserves the electrical ratings, circuit configuration, mounting dimensions, and termination style required for direct replacement in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the ASD320NU be used as a direct replacement for the ASD320N?

A: Yes. The ASD320NU is manufactured by IDEC under the same base product number (ASD320) and maintains all critical electrical specifications, circuit configuration, mounting type, and termination style. The transition from obsolete to active product status makes this substitution necessary for continued system support.

Q: Are there differences in packaging between the ASD320N and ASD320NU?

A: The ASD320N packaging specification is not provided in the technical data. The ASD320NU is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same regulatory certifications?

A: Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.50.9025) codes and maintain ROHS3 compliance. Certification details for CCC, CE, CSA, TUV, and UL should be verified with IDEC technical documentation for your specific application region.

Q: What is the moisture sensitivity level difference?

A: The ASD320N lists moisture sensitivity as not applicable. The ASD320NU is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This represents an improvement in handling and storage flexibility.

Q: Are the mechanical and electrical life ratings identical?

A: The ASD320N specifies 500,000 mechanical life cycles. Electrical life and detailed cycle ratings for the ASD320NU should be confirmed with IDEC technical specifications to ensure alignment with your application duty cycle requirements.
