Substitute Part Grouping Explanation

The ASD22K20NU is identified as a direct substitute for the ASD22K20N based on the following substitution criteria:

Matching Parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Base Product Number: ASD22 (same product family)
• Panel Mount Configuration: Maintains identical mechanical interface
• Screw Terminal Termination: Preserves electrical connection method
• RoHS3 Compliance: Meets the same environmental standards as the original
• Moisture Sensitivity Level 1: Identical handling and storage requirements

The ASD22K20NU represents an active product variant within the same IDEC ASD22 keylock switch family, providing functional continuity for applications previously using the obsolete ASD22K20N.

Engineering Selection Recommendations

The ASD22K20NU is the designated substitute for the obsolete ASD22K20N. Selection of this component is supported by:

• Product Status Alignment: The ASD22K20NU maintains active product status, ensuring continued availability and manufacturer support compared to the obsolete ASD22K20N.
• Regulatory Compliance: Both components meet ROHS3 compliance requirements, maintaining consistency with environmental and regulatory standards.
• Manufacturer Continuity: Both components are manufactured by IDEC within the same ASD22 product family, ensuring design and performance consistency.
• Mechanical and Electrical Interface Preservation: Identical mounting type (panel mount), termination style (screw terminal), and moisture sensitivity classification ensure direct compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the ASD22K20NU be used as a direct replacement for the ASD22K20N?

A: Yes. Both components share the same manufacturer (IDEC), base product number (ASD22), mounting configuration (panel mount), termination method (screw terminal), and compliance certifications (ROHS3). The ASD22K20NU is the active variant of the same product family.

Q: What is the primary reason for substitution?

A: The ASD22K20N is obsolete. The ASD22K20NU provides functional continuity as an active product within the IDEC ASD22 keylock switch family.

Q: Are there packaging differences between these components?

A: The ASD22K20N packaging designation is not specified in the documentation. The ASD22K20NU is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both components meet the same environmental standards?

A: Yes. Both the ASD22K20N and ASD22K20NU are ROHS3 compliant and classified as Moisture Sensitivity Level 1 (Unlimited), indicating identical environmental handling and storage requirements.

Q: What inventory status should be considered for procurement?

A: The ASD22K20NU is currently in active production with 754 pieces available in stock. The ASD22K20N, being obsolete, has limited remaining inventory (996 pieces noted as new original stock). For new designs and long-term applications, the ASD22K20NU is the appropriate selection.
