Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K22N-RLC is determined by strict equivalence across the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Circuit Configuration: 4PST-2NO/2NC (contact arrangement must match)
• Number of Positions: 3 (functional requirement)
• Current and Voltage Ratings: 10A AC / 110V and 8A DC / 24V (electrical performance requirements)
• Actuator Type: Flat Key (mechanical interface requirement)
• Mounting Type: Panel Mount (installation requirement)
• Termination Style: Screw Terminal (connection requirement)
• Panel Cutout Dimensions: Circular - 30.50mm Dia (mechanical fit requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part ASD3K22NU-RLC is identified as a direct equivalent based on these parameters.

Engineering Selection Recommendations

The ASD3K22NU-RLC is the designated substitute for the obsolete ASD3K22N-RLC. Selection is based on the following engineering criteria:

• Product Status Alignment: The substitute part maintains Active status, ensuring continued availability and manufacturer support, whereas the main part is Obsolete.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, confirming environmental and regulatory equivalence.
• Manufacturer Continuity: Both parts are manufactured by IDEC, ensuring design and performance consistency.
• Inventory Availability: The substitute part is available in bulk packaging with 945 units in stock, providing reliable supply for replacement and new installations.

Frequently Asked Questions (FAQ)

Q: Can ASD3K22NU-RLC be used as a direct replacement for ASD3K22N-RLC?

A: Yes. The ASD3K22NU-RLC is the designated substitute part. Both components share identical electrical specifications, mechanical mounting requirements, and regulatory compliance status.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The ASD3K22N-RLC is obsolete, while the ASD3K22NU-RLC is active. The suffix variation (-RLC vs -NU-RLC) indicates a product line update by IDEC. Both parts maintain equivalent functional and electrical performance.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in available documentation. The substitute part is supplied in bulk packaging. Confirm packaging requirements with your procurement process before ordering.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ASD3K22N-RLC and ASD3K22NU-RLC are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: What are the critical parameters for substitution?

A: Substitution is valid based on matching circuit configuration (4PST-2NO/2NC), 3-position operation, current ratings (10A AC / 8A DC), voltage ratings (110V AC / 24V DC), panel-mount installation, screw terminal connections, and 30.50mm circular panel cutout dimensions.
