Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K22N-310 is determined by strict alignment of electrical and mechanical parameters. The substitute part ASD3K22NU-310 maintains compatibility based on the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration: 4PST contact arrangement
• Current and voltage ratings: 10A AC / 8A DC capability
• Contact material: Silver (Ag) composition

Mechanical Compatibility Criteria:

• Actuator type: Flat key operation
• Mounting configuration: Panel mount with screw terminals
• Panel cutout dimensions: Circular 30.50mm diameter
• Depth behind flange: 76.00mm
• Operating temperature range: -25°C to 50°C

Compliance Criteria:

• RoHS3 compliance requirement
• Moisture sensitivity level: MSL 1

The ASD3K22NU-310 satisfies all specified parameters, establishing it as a direct functional equivalent for the obsolete ASD3K22N-310.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K22NU-310 is the direct substitute for the obsolete ASD3K22N-310. Both components are manufactured by IDEC and maintain identical electrical ratings, mechanical dimensions, and contact specifications. The substitute part is currently in active production status, ensuring availability for replacement applications.

Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The primary distinction is product lifecycle status: the original part is obsolete while the substitute remains actively manufactured and stocked.

Selection of the ASD3K22NU-310 is appropriate for all applications previously served by the ASD3K22N-310, provided that panel cutout dimensions and mounting depth accommodate the specified 30.50mm circular opening and 76.00mm depth behind flange.

Frequently Asked Questions (FAQ)

Q: Can the ASD3K22NU-310 directly replace the ASD3K22N-310 in existing installations?

A: Yes. Both components share identical electrical ratings (10A AC at 110V, 8A DC at 24V), circuit configuration (4PST-2NO/2NC), mechanical dimensions, and mounting specifications. Panel cutout and depth requirements are identical.

Q: What is the primary reason for substitution?

A: The ASD3K22N-310 is obsolete. The ASD3K22NU-310 is the active equivalent from the same manufacturer, maintaining all functional and dimensional specifications.

Q: Are there packaging differences between these parts?

A: The ASD3K22N-310 uses standard packaging while the ASD3K22NU-310 is supplied in bulk packaging. This distinction does not affect component functionality or performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 rating (unlimited moisture sensitivity level).

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify that your application requires 3-position keylock operation, 4PST-2NO/2NC contact configuration, 10A AC or 8A DC current capacity, and panel mount installation with screw terminals. Confirm that the panel cutout accommodates a 30.50mm circular opening and that 76.00mm depth behind the flange is available.

Q: Are the contact materials identical?

A: Yes. Both parts use silver (Ag) contact material, ensuring equivalent electrical performance and reliability.
