I found your direct replacement if you ever need one again. Here is a little more information to help.
Your P/N was:
A303E-CL G/W
A signifies Common Anode.
E designates color as Red High Efficiency.
G = Green, Y = Yellow, R = Super Red
Therefore the P/N equivalents would be A303X with X being any letter. Looking at the specifications, the current and voltage differences are insignificant from a circuit functionality perspective for what we need these for.
The readout is a 3 digit, 24 LED.
Mfg: American Opto Plus
Pinout indicates no connection for pin 10.
Pin 1 starts Lower Left looking from top view of readout through the device

The readout cost was $3.36 each for the exact replacement and $3.31 for other colors.
Leadtime is about 4-6 weeks if they do not have it in stock.
They had green in stock so I bought 3 and back ordered the exact parts.
