OEM numbers are pretty well meaningless, just because you managed to find something with asimilar number doesn't mean it's the same part.
Like I said, it's an NTC for inrush current limiting, as it's absolutely clear from the circuit.
You could easily replace it with a 4.7 or 10 ohm 5W wirewound resistor, certainly for testing purposes.
As far as replacing it with the correct part goes, get the exact spare part from Panasonic, and certainly not something with a similar number but a completely different function.
