Perrier, Google finds a Siemens NI1000 sensor that follows the nickel curve. Nickel is popular in industrial control for cost, but not as accurate as platinum. Converting the platinum curve to accurate temperatures requires a second order equation, but has been done with 0.1% analog converters.
Digi-key has ZNI devices as surface mount parts. Sparse data said nothing about a platinum curve. I'm curious because my former employer did very well selling platinum RTD sensors, usually 100 ohms at the triple point.

One simple inexpensive one to consider would be the ZNI1000Temperature sensor. It's 1K ohms at 0C and it replicates the temperature curve of the Pt 1K ohm sensors. It's about $3 from Digi-Key.
