Are these IC the same?
NO

Don't expect more than 5mA from that nanoAmp OA. 10mA is ABS MAX.

So just increase R to the appropriate value.

The answers are usually in the datasheet.

Fig 3,4,5 Indicate this IC is not intended for driving LEDs. Using the slope of Vol/Iol as the driver impedance, I compute;

Vcc vs Ro

2.7 V ... 2.7 kΩ
5.0 V ... 1.6 kΩ
15. V ... 1 kΩ

When in doubt verify all pin voltages, especially Vout.
