bb505 varactor ebay

hello

i have a fm receiver circuit using TDA 7000 IC. it also uses a varactor diode MV 2105. the capacitance of the diode is 2-16pf. i cannot find the diode. so, can i substitute the varactor diode with a fixed ceramic capacitor of 16pf ? or if there is another way, please let me know.

i am enclosing the circuit diagram.

fm receiver and bb105

You can use BB105, BB405 or BB505 instead MV2105.
You must not replace it with fixed capacitor because this diode is used for receiver tunning.
