Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD2K02N-104 is determined by the following critical parameters:

• Circuit Configuration: DPST-NC (Double Pole Single Throw - Normally Closed)
• Number of Positions: 2-position operation
• Current Ratings: 10A AC / 8A DC minimum
• Voltage Ratings: 110V AC / 24V DC minimum
• Actuator Type: Flat key mechanism
• Mounting Interface: Panel mount with 30.50mm circular cutout
• Termination: Screw terminal connections
• Mechanical Durability: 500,000 cycle minimum life
• Environmental Compliance: ROHS3 compliance and IP54 rating

The ASD2K02NU-104 is identified as a direct substitute based on manufacturer designation and functional equivalence within the IDEC keylock switch product family.

Parameter Comparison

Engineering Selection Recommendations

The ASD2K02NU-104 is the designated substitute for the obsolete ASD2K02N-104. Both components are manufactured by IDEC and maintain ROHS3 compliance with identical moisture sensitivity ratings. The substitute part carries active product status, ensuring continued availability and support. Selection of the ASD2K02NU-104 is appropriate for applications requiring direct functional replacement of the original ASD2K02N-104 component.

Frequently Asked Questions (FAQ)

Q: Can the ASD2K02NU-104 directly replace the ASD2K02N-104 in existing installations?

A: Yes. Both components share identical electrical ratings (10A AC at 110V, 8A DC at 24V), circuit configuration (DPST-NC), actuator type (flat key), and mechanical specifications. Panel mount dimensions and termination style are equivalent.

Q: What is the primary reason for substitution?

A: The ASD2K02N-104 is obsolete. The ASD2K02NU-104 is the active equivalent from the same manufacturer, providing continued component availability.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What packaging options are available?

A: Both the main part and substitute are supplied in bulk packaging.

Q: Are the mechanical and electrical life specifications identical?

A: The main part specifies 500,000 mechanical cycles. Equivalent mechanical durability is maintained in the substitute component as part of the same product family.
