I cannot find these anywhere or a suitable substitute. Any suggestions?

m7549 isn't recognized as the part number of an electronic component by Google. Do you have photos?

Hello,

Are there more details on the part?
A picture would help.

Would you estimate the vintage of the equipment as being75-85 'ishl? . . . As that numbering is certainly more in line as being a date code of the 49th week of 1975 .
And also when Motorola was Motorola and not ON Semiconductor.
