SOT-23-5 is a small but hand-solderable package. The thermal mass is low, so it reflows cleanly under hot air.
Yes, it is ROHS3 compliant.
The SN74LVC1G32 is a similar single 2-input OR gate but from the 74LVC family. The key difference is the supply range: the 74LVC variant typically operates from 1.65 V to 5.5 V and has slightly different input thresholds. The 74LV1T32 is specifically designed for level translation with wider input threshold headroom at low VCC. Both are active, but the 74LV1T32 is the better choice when mixing 1.8 V and 3.3 V logic.
No direct replacement is listed by TI. The SN74AHC1G32DCKT is a functional alternative from the 74AHC family, but it has a narrower supply range (2 V to 5.5 V) and a smaller temperature range (-40°C to 85°C). For a drop-in pin-compatible replacement, stick with the SN74LV1T32DBVR.
