ASD22K22N Equivalent & Substitute Parts

Part Overview

The ASD22K22N is a keylock switch manufactured by IDEC, featuring a 2-position, 4PST configuration with dual normally open and dual normally closed contacts. This panel-mount switch is rated for 10A AC at 110V and 8A DC at 24V, with an IP54 rating and mechanical life of 500,000 cycles. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD22K22N is determined by strict alignment of electrical and mechanical parameters. The substitute part ASD22K22NU maintains compatibility through the following critical parameters:

• Circuit configuration: 4PST-2NO/2NC (dual normally open, dual normally closed contacts)
• Number of positions: 2-position operation
• Current ratings: 10A AC and 8A DC minimum
• Voltage ratings: 110V AC and 24V DC minimum
• Actuator type: Flat key mechanism
• Contact material: Silver (Ag)
• Mounting interface: Panel mount with circular 30.50mm cutout
• Termination: Screw terminal connection
• Environmental compliance: ROHS3 Compliant, MSL 1

The ASD22K22NU is classified as an active product from the same manufacturer, providing direct functional and physical compatibility with the obsolete ASD22K22N.

Parameter Comparison

Engineering Selection Recommendations

The ASD22K22NU is the direct substitute for the obsolete ASD22K22N. Both components are manufactured by IDEC and maintain identical electrical specifications, circuit configurations, and mechanical interfaces. The ASD22K22NU carries active product status, ensuring continued availability and supply chain support. Both parts meet ROHS3 compliance requirements and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. Selection of the ASD22K22NU eliminates obsolescence risk while preserving full functional compatibility with existing panel mount installations designed for the ASD22K22N.

Frequently Asked Questions (FAQ)

Q: Can the ASD22K22NU directly replace the ASD22K22N in existing installations?

A: Yes. The ASD22K22NU maintains identical electrical ratings (10A AC at 110V, 8A DC at 24V), circuit configuration (4PST-2NO/2NC), mechanical interface (panel mount, 30.50mm circular cutout), and termination style (screw terminal). Physical and functional compatibility is complete.

Q: What is the primary reason for substitution?

A: The ASD22K22N is obsolete. The ASD22K22NU is the active equivalent from the same manufacturer, providing continued component availability and supply chain support.

Q: Are there packaging differences between these parts?

A: The ASD22K22N is listed with standard packaging, while the ASD22K22NU is supplied in bulk packaging. This does not affect component functionality or installation compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the ASD22K22N and ASD22K22NU are ROHS3 compliant with MSL 1 rating. Operating temperature range is -25°C to 50°C for both components.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by matching circuit configuration (4PST-2NO/2NC), current and voltage ratings (10A AC/110V, 8A DC/24V), actuator type (flat key), contact material (silver), mounting interface (panel mount with 30.50mm cutout), and termination style (screw terminal).
