ASD2K20N Equivalent & Substitute Parts

Part Overview

The ASD2K20N is a keylock switch manufactured by IDEC, classified as a 2-position DPST-NO switch rated for 10A AC at 110V and 8A DC at 24V. This component is designed for panel-mount applications with screw terminal connections and features IP54 protection. The product is currently obsolete, making identification of compatible substitute parts essential for maintenance, repair, and system continuity in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD2K20N is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration: DPST-NO (Double Pole Single Throw, Normally Open)
• Current ratings: 10A AC / 8A DC minimum
• Voltage ratings: 110V AC / 24V DC minimum

Mechanical Compatibility:

• Actuator type: Flat Key
• Mounting configuration: Panel Mount
• Termination: Screw Terminal
• Panel cutout: 30.50mm circular diameter
• Depth behind flange: 53.00mm

Regulatory & Environmental:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• Operating temperature range: -25°C to +50°C

The substitute part ASD2K20NU maintains equivalence across all specified electrical and mechanical parameters while offering active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

The ASD2K20NU is a direct functional equivalent to the ASD2K20N. Both components are manufactured by IDEC and maintain identical electrical specifications (10A AC at 110V, 8A DC at 24V), mechanical configuration (panel mount with screw terminals), and regulatory compliance (ROHS3). The primary distinction is product status: the ASD2K20N is obsolete while the ASD2K20NU is active and currently in stock.

For new designs or system replacements, the ASD2K20NU is the appropriate selection. For existing installations using the ASD2K20N, the ASD2K20NU provides direct substitution without circuit modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the ASD2K20NU directly replace the ASD2K20N in existing installations?

A: Yes. The ASD2K20NU is electrically and mechanically equivalent. It maintains the same DPST-NO circuit configuration, current and voltage ratings, panel cutout dimensions, screw terminal connections, and operating temperature range. No circuit or mechanical modifications are required.

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

A: The ASD2K20N is an obsolete product from the TWTD series. The ASD2K20NU is the active equivalent from the current IDEC product line. Both components share identical functional specifications and are ROHS3 compliant with MSL 1 rating.

Q: Are there any packaging differences between ASD2K20N and ASD2K20NU?

A: The ASD2K20NU is supplied in bulk packaging. Packaging configuration should be confirmed with your supplier based on order quantity and application requirements.

Q: What electrical parameters must be matched for substitution?

A: Critical electrical parameters are circuit type (DPST-NO), current rating (10A AC minimum, 8A DC minimum), and voltage rating (110V AC minimum, 24V DC minimum). The ASD2K20NU meets or exceeds all specified ratings.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the ASD2K20N and ASD2K20NU are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). The ASD2K20NU carries ECCN EAR99 classification.
