Honeywell LSA8A7 Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell LSA8A7 is a snap action SPDT (Single Pole Double Throw) switch designed for chassis mount applications. This component features a side rotary actuator without lever, rated for 10A AC at 120V and 800mA DC at 115V, with integrated status indicator functionality. The LSA8A7 operates within the HDLS series and is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LSA8A7 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is established based on the following criteria:

Electrical Equivalence: Identical circuit configuration (SPDT DB/DM), switch function (On-Momentary), current ratings (10A AC / 800mA DC), and voltage ratings (120V AC / 115V DC).

Mechanical Equivalence: Matching actuator type (Side Rotary - No Lever), mounting configuration (Chassis Mount), termination style (Plug In), and operational characteristics (Operating Force 46gfm, Pretravel 15°, Differential Travel 5°, Overtravel 60°).

Environmental Compliance: Identical operating temperature range (-12°C to 93°C), RoHS compliance status, and Moisture Sensitivity Level (MSL 1).

Series Continuity: Both parts belong to the Honeywell HDLS series and share the same status indicator feature.

The LSA5A substitute part maintains full parameter equivalence while offering active product status, ensuring continued availability and manufacturer support.
