AD120-00 Equivalent & Substitute Parts Reference

Part Overview

The AD120-00 is an omnipolar Hall Effect magnetic switch manufactured by NVE Corp/Sensor Products. This digital switch operates as an open collector device and detects both north and south magnetic poles within a ±3.4mT trip threshold and ±1.4mT release threshold. The device is currently classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the AD120-00 is determined by strict equivalence across the following critical parameters:

Functional Parameters: The substitute must maintain identical omnipolar Hall Effect switching function with open collector output topology.

Electrical Parameters: Supply voltage range (4.5V ~ 30V), maximum supply current (4.5mA), and maximum output current (20mA) must remain unchanged.

Magnetic Sensing Parameters: The sensing range thresholds (±3.4mT trip, ±1.4mT release) and dual-pole detection capability must be preserved.

Thermal Parameters: Operating temperature range (-40°C ~ 125°C) must be maintained.

Mechanical Parameters: Surface mount packaging in 8-MSOP configuration with identical physical dimensions (0.118", 3.00mm Width) is required for PCB compatibility.

The AD120-00E qualifies as a direct substitute because it maintains all specified electrical, magnetic, thermal, and mechanical parameters while offering active product status and improved compliance certification.
