Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K22N-309 is determined by the following critical parameters:

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

The substitute part ASD3K22NU-309 maintains compatibility across these critical parameters while offering active product status and improved availability.

Engineering Selection Recommendations

The ASD3K22NU-309 is the direct substitute for the obsolete ASD3K22N-309. Selection is based on the following engineering criteria:

• Product Status Alignment: The substitute part maintains active product status, ensuring long-term availability and continued manufacturer support, whereas the original part is obsolete and subject to discontinuation.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 rating, meeting current environmental and moisture sensitivity requirements.
• Inventory Availability: The substitute part demonstrates higher current inventory levels (1074 Pcs vs. 897 Pcs), supporting immediate procurement needs.
• Manufacturer Continuity: Both parts are manufactured by IDEC, ensuring design consistency and compatibility with existing panel-mount installations.

Frequently Asked Questions (FAQ)

Q: Can the ASD3K22NU-309 directly replace the ASD3K22N-309 in existing installations?

A: Yes. Both parts share identical electrical specifications (10A AC at 110V, 8A DC at 24V), circuit configuration (4PST-2NO/2NC), mechanical mounting (panel mount with 30.50mm circular cutout), and termination style (screw terminal). The substitute part is designed as a direct replacement for the obsolete original.

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

A: The primary difference is product status. The ASD3K22N-309 is obsolete, while the ASD3K22NU-309 is active. The substitute part is based on the ASD3 base product line and is available in bulk packaging, offering improved long-term availability and supply chain stability.

Q: Are there any compatibility concerns with panel cutout dimensions?

A: No. Both parts maintain the same panel cutout specification (circular 30.50mm diameter) and depth behind flange (76.00mm), ensuring mechanical compatibility with existing panel installations without modification.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the ASD3K22N-309 and ASD3K22NU-309 are ROHS3 compliant and carry MSL Level 1 rating, meeting current environmental and moisture sensitivity standards.

Q: What is the mechanical life expectancy?

A: The ASD3K22N-309 is rated for 500,000 mechanical cycles. Equivalent mechanical life specifications for the substitute part should be verified with IDEC technical documentation if this parameter is critical to your application.
