Equivalent & Substitute Parts Reference for ASD33K02N Keylock Switch

Part Overview

The IDEC ASD33K02N is a DPST-NC keylock switch with 3 positions, rated for 10A (AC) and 8A (DC), designed for 110 VAC and 24 VDC operation. Intended for panel mount installations, it features a flat key actuator, screw terminal connections, and IP54 protection. The ASD33K02N has reached obsolete status, necessitating identification of alternative models with strictly comparable electrical and mechanical parameters to ensure form, fit, and function compatibility.

Engineering Selection Recommendations

The main part, IDEC ASD33K02N, is obsolete. The substitute, ASD33K02NU, is active and shares identical compliance statuses, including RoHS3 and an MSL rating of 1 (Unlimited Shelf Life). Selection between these models should be based on product status and provided certifications. Only substitute parts meeting all compliance and life cycle requirements should be selected.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when substituting a keylock switch in this category?
A1: Substitutes must match manufacturer, series/base number, circuit type, number of positions, switch function, current and voltage ratings, actuator type, mounting type, termination style, and compliance specifications.

Q2: Is ASD33K02NU a direct replacement for ASD33K02N?
A2: ASD33K02NU is listed as a direct substitute based strictly on provided electrical, mechanical, and compliance parameters.

Q3: Are packaging differences relevant for substitute selection?
A3: Both ASD33K02N and ASD33K02NU are supplied in bulk packaging. No variance is present in packaging with respect to substitution.

Q4: How does part status affect engineering selection?
A4: ASD33K02N is obsolete; only active-status substitutes meeting compliance and lifecycle details should be selected to ensure supportability and availability.

Q5: Do RoHS and MSL ratings impact compatibility?
A5: Both main and substitute parts show RoHS3 compliance and identical MSL ratings, ensuring equivalence in environmental and handling attributes.
