This was in one side of the 120VAC line of an oil-filled space heater.

It's open now, and I'd like to get a replacement. Have tried the
semiconductor datasheet sites - no luck.

In addition to the D125ZCVJ marking, there's a stylized "E" and "128ºC" on
it.

The heater is rated at 1500W, so assume this device would be rated about 13
amps.

It's a thermal fuse. You can use an NTE8125
