Unusual package, I can get hold of the usual 1.25mm pin spacing SMD 8
pin SOIC IC . I might be able to find an exact replacement if I knew the
SMD style code for .75mm spacing, normal width of SOIC IC body but not
so long.
May be about .75mm pitch , not exactly .75, only ruler measurement.
At a pinch I might be able to twist 90 degree each pin axially and
realign for the smaller pitch, and/or grind back the pin width with .5mm
dremmel discs, but very constrained space and an exact replacement would
be a lot easier.
