This is a delay module that lets the game pause momentarily while something of indeterminate duration happens. This is used for example on Flip A Card where a spinner needs to stop spinning before the game can tell what card you've earned. Since there's no spinner EOS switch, the game just waits patiently for a bit and hopes that the spinner has stopped by the time the delay is over.

If your delay is working I'd leave it alone. If you feel compelled though you can replace the individual parts as you see fit since they're identified in the picture you posted. I doubt anyone would offer these new so any you find will likely be about as old as yours.

Gottlieb used this unit in a number of titles in the 70's. I have a Gottlieb 1975 'Top Score' which has a similar unit used as a 'Bonus Delay Unit'. Example, when the ball in play lands in a selected 'kick out hole' a mystery score bonus is awarded. (If the unit is unplugged, only a set score will be awarded).

If required, you could replace the unit with new components. Below is a drawing of the unit used in my 'Top Score' machine. You will see that the component values do differ slightly.
