I've never seen the Radio Shack part but I found this on the Radio Shack

Infrared Emitter and Detector Pair
(276>-<0142) Hints and Tips Faxback Doc. # 17161
Q: Unable to identify the parts.
A: Set the devices on a table with the lens facing up and pins facing the

The clear device is the LED. The anode is on the left and the cathode
on the right.
