ASD2K11N Equivalent & Substitute Parts

Part Overview

The ASD2K11N is a keylock switch manufactured by IDEC, designed for panel-mounted applications requiring 2-position DPST-NO/NC switching. This component is rated for 10A at 110 VAC and 8A at 24 VDC, with silver contacts and screw terminal connections. The part is currently obsolete, making identification of suitable substitutes essential for maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD2K11N is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPST-NO/NC)
• Number of positions (2)
• Current ratings (10A AC / 8A DC minimum)
• Voltage ratings (110V AC / 24V DC minimum)
• Actuator type (Flat Key)
• Contact material (Silver)
• Mounting type (Panel Mount)
• Termination style (Screw Terminal)
• Panel cutout dimensions (Circular 30.50mm Dia)
• Depth behind flange (53.00mm)
• Operating temperature range (-25°C to 50°C)
• Mechanical life (500,000 Cycles)

The ASD2K11NU meets all these parameters and is identified as a direct substitute for the obsolete ASD2K11N.

Parameter Comparison

Engineering Selection Recommendations

The ASD2K11NU is the designated substitute for the obsolete ASD2K11N. Both components are manufactured by IDEC and maintain ROHS3 compliance with MSL 1 rating. The ASD2K11NU carries active product status, ensuring availability for procurement and support. Selection of the ASD2K11NU eliminates obsolescence risk while maintaining compatibility with existing panel mount installations requiring 2-position keylock switching functionality.

Frequently Asked Questions (FAQ)

Q: Can the ASD2K11NU directly replace the ASD2K11N in existing installations?

A: Yes. Both components share identical mounting specifications (panel mount, 30.50mm circular cutout, 53.00mm depth), termination style (screw terminal), and circuit configuration (DPST-NO/NC). The ASD2K11NU is the manufacturer-designated substitute.

Q: What is the difference in packaging between these parts?

A: The ASD2K11N packaging is listed as "-" (not specified), while the ASD2K11NU is supplied in Bulk packaging. This affects procurement and handling but does not impact functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASD2K11N and ASD2K11NU are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Why is the ASD2K11N obsolete?

A: The ASD2K11N has reached end-of-life status. The ASD2K11NU represents the active continuation of this product line from IDEC.

Q: What electrical specifications should I verify for my application?

A: Confirm that your application requirements do not exceed 10A at 110 VAC or 8A at 24 VDC. Verify operating temperature range compatibility (-25°C to 50°C) and mechanical cycle life requirements (500,000 cycles minimum).
