The new ones are OC81M which are miniature versions of the OC81 and should be suitable. The leads are in a triangular configuration with the collector next to the black line. The base is the middle lead and the emitter being the remaining lead. The OC81 has the three leads in line with the collector next to the red dot, base in the middle and the emitter being furthest away from the red dot. (Also the base collector spacing is usually greater than the base emitter spacing.
