Substitute Part Grouping Explanation

Substitution of the ASD2K22N is determined by electrical and mechanical compatibility across the following critical parameters:

• Circuit Configuration: 4PST-2NO/2NC switching arrangement
• Electrical Ratings: 10A (AC) / 8A (DC) current capacity; 110 VAC / 24 VDC voltage compatibility
• Mechanical Interface: Panel mount with circular 30.50mm cutout; screw terminal connections
• Actuator Type: Flat key actuation mechanism
• Environmental Compliance: ROHS3 compliance and MSL rating

The ASD2K22NU qualifies as a direct substitute based on manufacturer lineage (IDEC base product ASD2) and maintained electrical specifications. The substitute part retains the core functional parameters necessary for drop-in replacement in legacy applications.

Engineering Selection Recommendations

The ASD2K22NU is the designated substitute for the obsolete ASD2K22N. Selection is based on the following engineering criteria:

• Product Status Alignment: The ASD2K22NU maintains active production status, ensuring availability and supply chain continuity for replacement applications.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, confirming environmental and regulatory compatibility.
• Manufacturer Continuity: Both components are manufactured by IDEC and share the same base product platform (ASD2), indicating design and functional equivalence.
• Electrical and Mechanical Specifications: The substitute part preserves the electrical ratings, circuit configuration, and mechanical interface parameters required for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can the ASD2K22NU directly replace the ASD2K22N in existing installations?

A: Yes. The ASD2K22NU is a direct substitute. Both parts share identical electrical ratings (10A AC / 8A DC, 110 VAC / 24 VDC), circuit configuration (4PST-2NO/2NC), mechanical mounting interface (panel mount, 30.50mm circular cutout), and termination style (screw terminal). The substitute maintains ROHS3 compliance and MSL rating equivalence.

Q: What is the primary reason for substitution?

A: The ASD2K22N is obsolete and no longer in production. The ASD2K22NU is the active equivalent from the same manufacturer, ensuring continued availability for replacement and maintenance applications.

Q: Are there any packaging differences between the main part and substitute?

A: The ASD2K22N packaging specification is not defined in the available data. The ASD2K22NU is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts have the same environmental ratings?

A: Yes. Both the ASD2K22N and ASD2K22NU operate across the -25°C to 50°C temperature range, maintain IP54 protection rating, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What certifications apply to the substitute part?

A: The ASD2K22NU is ROHS3 compliant and classified under ECCN EAR99 with HTSUS code 8536.50.9025.
