Subject: [Heath] LCD replacement for Heathkit IM- 2215 DVM, part<br>
411-843<br>

<br>
Hello,<br>
<br>
The LCD display on my IM-2215 meter is deteriorating and I'm trying <br>
to find a replacement. It's Heathkit part #411-843, and <br>
cross-references to:<br>
Beckman 739-02050<br>
Hamlin 3933-363-159<br>
AND DISPLAYS FE0203<br>
<br>
Can't find any of those, but Newark lists these 2:<br>
FE0203W-EU<br>
FE0203W-DU<br>
at very slightly different prices, with only the -DU in stock.<br>
<br>
Does anyone know if these can be directly substituted for the <br>
original Heathkit #411-843 LCD?<br>
From the online information I don't see what the differences are, if <br>
any, or if they can be substituted.<br>
And, can anyone suggest sources?<br>
<br>
Thanks.<br>
John KE5ZB<br>
