TT23K2T Toggle Switch DPST 3A 125V Equivalent & Substitute Parts

Part Overview

The TT23K2T is a DPST (Double Pole Single Throw) toggle switch manufactured by TE Connectivity ALCOSWITCH Switches, rated for 3A at 125V AC and 28V DC. This panel-mount switch features a standard round actuator with solder lug termination and operates across a temperature range of -30°C to 85°C. The TT23K2T is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and termination characteristics to ensure direct replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 1825222-6 be used as a direct replacement for the TT23K2T?

A: Yes. The 1825222-6 is electrically and mechanically identical to the TT23K2T across all critical parameters: DPST circuit, 3A/125V AC/28V DC ratings, panel mount configuration, 7.52mm round actuator, 4.83mm circular panel cutout, 10-48 bushing thread, and solder lug termination. No circuit redesign or mechanical modification is required.

Q: What is the difference between the TT23K2T and 1825222-6?

A: The primary differences are product status and electrical life. The TT23K2T is obsolete with 20,000-cycle electrical life, while the 1825222-6 is active with 80,000-cycle electrical life. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel cutout dimensions?

A: No. Both parts feature identical panel cutout dimensions (circular, 4.83mm diameter) and bushing thread specification (10-48), ensuring mechanical compatibility with existing panel installations.

Q: Does the substitute part require different solder lug specifications?

A: No. Both parts use identical solder lug termination style, requiring no changes to PCB layout or wire attachment procedures.

Q: What is the operating temperature range for both parts?

A: Both the TT23K2T and 1825222-6 operate across -30°C to 85°C, providing identical thermal performance.

Q: Are export control classifications the same?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, with no changes to regulatory compliance or shipping requirements.
