Hello Rachel,
Indeed, the KTY84-130’s status is End of life, which means that the capacity is declining rapidly. Formal discontinuance notice may be issued.
In this case I would like to recommend the KTY81: Silicon temperature sensors.
The temperature sensors in the KTY81 series have a positive temperature coefficient of resistance and are suitable for use in measurement and control systems. The sensors are encapsulated in the SOD70 2 in-line leads plastic package.
You may find more information here.
Please let me know if this recommendation is useful for you.
If I misunderstood your question, feel free to let me know. I will be glad to help.
Have a great day.
David Diaz.
