Is Hall Sensor 503 Pin-Compatible and Functionally Equivalent to Allegro A1302?

Hello, guys!
I do some exercise about A1302 recently, but the a1302 seems a little difficult to get. I search for some materials, such as its datasheet below, some articles about A1302, I want to be sure whether the Hall sensor 503 could replace A1302, or not?

Good listening!

I had a quick look at the data sheets for these components.

The A1301 and 1302, from the data sheet you posted, give a linear output dependent on the strength of the magnetic field applied to it.

The HAL502 = Datasheet here

https://www.digchip.com/datasheets/parts/datasheet/922/HAL502A-pdf.php

is a completely different thing. It gives a latching output either 1 or 0 depending on the polarity of the magnetic field applied to it, and retains the state when the magnetic field is removed. so definitely not a drop-in replacement or even one you could redesign for.

Looking on the Allegro website, it seems the 1302 is discontinued, but put "Linear hall effect sensor" into their website's search box and you get a lot of results.

Not knowing where you are makes it difficult to recommend a supplier who may help you.

Rachel Anne I happend to find this on Element 14 (I think Farnell in UK, Newark in the US, this is the Australian site):

A1326 - later model, same manufacturer. Very similar characteristics on a quick inspection, maybe a bit more sensitive. And only about $1 each! Maybe those would do what you want. A data sheet is available at the link or here
