Substitute Part Grouping Explanation

Substitution of the ASD2K22N-111-RL is based on electrical and mechanical compatibility within the IDEC keylock switch product family. The primary substitute identified is the ASD2K22NU-111-RL, which maintains the same base electrical specifications: 2-position keylock configuration, 4PST contact arrangement, 10A AC / 8A DC current ratings, and 110V AC / 24V DC voltage ratings. Both components share identical mechanical mounting characteristics including panel mount configuration, screw terminal termination, 30.50mm circular panel cutout, and 76.00mm depth behind flange.

The substitution logic is based on the following critical parameters:

• Circuit configuration (4PST-2NO/2NC)
• Electrical ratings (10A AC, 8A DC, 110V AC, 24V DC)
• Mechanical mounting interface (panel mount, screw terminals)
• Physical dimensions (panel cutout and depth)
• Actuator type (flat key)

Engineering Selection Recommendations

The ASD2K22NU-111-RL is designated as the direct substitute for the obsolete ASD2K22N-111-RL. Selection of this substitute is supported by the following factors:

The substitute part maintains active product status with IDEC, ensuring ongoing availability and manufacturer support. Both components are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), confirming equivalent environmental handling and storage requirements. The substitute is available in bulk packaging with current inventory of 760 pieces, providing supply continuity for production and maintenance applications.

The ASD2K22NU-111-RL is classified under ECCN EAR99 with HTSUS code 8536.50.9025, indicating standard commercial classification for electrical switches. This substitution is appropriate for applications requiring 2-position keylock switch functionality with 4PST contact configuration in panel mount installations.

Frequently Asked Questions (FAQ)

Q: What makes ASD2K22NU-111-RL a suitable substitute for ASD2K22N-111-RL?

A: Both components are manufactured by IDEC and share the same base product designation (ASD2). The substitute maintains the same electrical ratings (10A AC, 8A DC, 110V AC, 24V DC), circuit configuration (4PST-2NO/2NC), and mechanical mounting interface (panel mount with screw terminals and 30.50mm circular cutout). The substitute is currently in active production status, whereas the original part is obsolete.

Q: Are there any differences in compliance or environmental ratings between these parts?

A: Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level ratings (MSL 1 - Unlimited). No differences exist in environmental compliance or handling requirements.

Q: What is the inventory situation for these substitute parts?

A: The ASD2K22NU-111-RL is available in bulk packaging with 760 pieces currently in stock. The original ASD2K22N-111-RL has 815 pieces available but is classified as obsolete.

Q: Can the ASD2K22NU-111-RL be used as a direct replacement in existing installations?

A: The substitute maintains identical mechanical mounting dimensions (panel cutout 30.50mm diameter, depth 76.00mm) and termination style (screw terminal), supporting direct installation in existing panel mount applications designed for the original part.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by circuit configuration (4PST-2NO/2NC), current ratings (10A AC / 8A DC), voltage ratings (110V AC / 24V DC), and actuator type (flat key). These parameters must remain consistent between the original and substitute components.
