According to the parts list on p.15 of the [link|https://elektrotanya.com/sony_wm-a39_wm-b39_sm.pdf/download.html|service manual], THP601 is a PTC¹ type thermistor
¹ PTC = Positive Temperature Co-efficient = As the temperature increases, the resistance of the thermistor increases.
The part number is Sony 1-808-389-11 but unfortunately I couldn't find a replacement online when searching for the part number. You may have better luck.
What are the colours of the bands on the thermistor?

There's also a TPH602 on the board which uses the same thermistor. If you disconnect one lead of that thermistor from the board and then measure its resistance with an Ohmmeter, along with checking that its colour bands are the same as TPH601 you might get some idea of its value.
