I have a handheld signal generator intended for telecommunications purposes and it is fitted with a Hitachi LM016L 16 x 2 character display. The Display had taken a whack and was no longer functioning.

Since the LM016L is no longer readily available I compared the datasheet against the Displaytech 162H BA BW and found that it was a fairly close match both electrically and measurement wise. I decided it was worth a try so I purchased a 162H BA BW from Mouser and fitted it in the signal generator today. I can report that it works just fine.
