AD592BN Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The AD592BN is an analog temperature sensor manufactured by Analog Devices Inc., designed for local temperature measurement across the range of -25°C to 105°C. The device operates with a supply voltage of 4V to 30V and provides analog current output. The AD592BN is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and new design implementations. The AD592BNZ serves as the direct active equivalent, offering identical electrical and mechanical specifications with current manufacturing status.

Substitute Part Grouping Explanation

Substitution of the AD592BN is determined by strict equivalence across the following parameters:

Sensor type classification (Analog, Local)
Temperature sensing range (-25°C ~ 105°C)
Output type (Analog Current)
Supply voltage range (4V ~ 30V)
Accuracy specification (±1°C at 25°C)
Package and case designation (TO-92-3)
Mounting configuration (Through Hole)
Moisture sensitivity level (MSL 1)

The AD592BNZ maintains complete electrical and mechanical compatibility with the AD592BN across all specified parameters. The primary distinction is product status: AD592BN is obsolete while AD592BNZ is active in production.
