HMC1021Z Equivalent & Substitute Parts
Part Overview
The HMC1021Z is a magnetoresistive sensor manufactured by Honeywell Aerospace, designed as a single-axis magnetic field sensor with Wheatstone bridge output configuration. This component operates across a sensing range of ±0.6mT with a bandwidth of 5MHz and is housed in an 8-pin SIP through-hole package.
The HMC1021Z is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new design implementations where this sensor technology is required. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity.
