End-of-life and sourcing reality
The R88DKT50F: A BOM line holding this part should be reviewed for migration to a current-series equivalent — the nearest active replacement in the same frame size and current rating is the first candidate to evaluate with your Omron FAE.
What the 5 kW and 16.5 A ratings mean for fit
Rated 5 kW at 16.5 A continuous output, the R88DKT50F drives the mid-range motor frames in the Accurax G5 ecosystem — the compatible list spans the R88M-K3K010 through R88M-K5K030 series in both food-safe (F) and standard (C) variants, plus the R88M-K4K510C. At 16.5 A the drive sits at the upper end of the single-axis G5 current band — confirm the motor's continuous torque draw against this figure before committing; a motor running near its own current ceiling will thermally stress the drive's 55 °C operating limit.
Voltage and temperature envelope
The 323–528 V AC operating window covers standard 380–480 V industrial three-phase supplies with enough margin for supply sags and regeneration events. The 528 V upper bound is the abs-max before the drive trips on DC-bus overvoltage — in practice, a braking resistor sized for the deceleration duty cycle keeps the bus below this ceiling on fast stops. The 0–55 °C operating range is the derated ambient ceiling — the drive does not carry the full 5 kW at 55 °C; the datasheet derating curve governs the output current reduction above 40 °C. Enclosures without active cooling or with shared thermal loads from adjacent drives will push the ambient higher and cut output capability — budget accordingly at the machine-layout stage.
