These 4-pin optocouplers exist often in different styles, same type,
same plastic body, same chip inside, but the pins are formed as TH,
gull wings, J leads, different spacings etc. - mostly just one little
letter difference in the part number.

That means - just be careful and try to get a sample from your
customer on your desk before you put the wrong footprint in the
design. Been there, done that :-(
