one thing you should learn is reading datasheets .
If you open the datasheet for KSC1845, in the very beginning it will say
Audio Frequency Low Noise Amplifier
• Complement to KSA992
So there is your compement.
PS. I did not verify the KSC1845 being the NPN equivalent for 2SC870, so I will leave it to you as exercise - look at 1) Unity gain frequency, 2) Vc, 3) Beta (hFE), 4) packaging. Currents are not as important in here.
