No direct replacement is listed by TI. For a functional cross-shop, the TLV803EA29VDBZR is a similar Simple Reset/Power-On Reset with active-low open-drain output, but it has a 130ms typical timeout and a different threshold voltage — verify fit against your rail voltage and timing requirements before substituting.
The TLV853MDBZT and TLV853MDBZR are electrically identical. The suffix indicates packaging and reel quantity: MDBZT is Cut Tape (CT) for small-quantity prototyping, while MDBZR is Tape & Reel (TR) for production volume. Both share the same SOT-23-3 package, 4.38V threshold, and 120ms minimum timeout.
The device is a Simple Reset/Power-On Reset with an Active Low reset output. The output is Open Drain or Open Collector, so an external pull-up resistor is required.
