Axial Capacitor: Looks like a resistor??

Hi;
I am working on restoring my Turkey Shoot and on the CPU PCB it has a
load of 0.001uf 50v axial caps that have bands just like resistors.
I have to replace some and have to order replacements.
Can I use Multilayer Axial Ceramic Capacitors in their place??
(Mouser#581-SA101C102KAR)
Thanks
Jeff

Also, what is a SRC?
There are 2 on the PCB, SRC1 and SRC2
There is no listing of these items in the parts list in the manual.
They look like resistor packs but are fatter, any Idea?
I might have to replace them as well as there is a lot of acid damage.
Thanks
Jeff

They have lumped together some of those "glass" bypass caps as well
and I have used the ceramics in the past to replace those on my
Robotron PCBs' so I guess I could use the ceramics for all the 0.001uf
50v caps?

.001 sounds like bypass capacitors. The type you use shouldn't be critical.

Thanks James, I am placing the order w/ Mouser as we speak BUT before
I do,
do you have any idea of what the SRC 1 and SRC 2 are on the TS CPU
PCB?
I am afraid to touch them as there is alot of acid damage and they
will most likely break off when I do.
Thanks
Jeff

No idea without seeing. Are you sure those aren't SCR?

James;
The manuals list of materials for the CPU PCB states:
SR1;SR2;SR3;SR4 Resistor 4.7K ohm 10 pin SIP
SR5 Resistor 4.7K ohm 6 pin SIP
BUT
The PCB has SR1;SR2;SR3; SRC1;SRC2
I scraped the legs clean and got a resistor reading of 4.9K ohms from
the SRC 1 which leads me to believe that it too is a resistor pac but
it is taller and fatter, possibly a higher voltage??
The SR1;SR2;SR3 has written on it:
4701GL2
The SRC1;SRC2 has written on it:
CRL8352L CK-1
I tried to Google it but nothing came up.
They are still making contact to the PCB but not by much.
I already treated the board with vinegar and removed as much corrosion
as I could without damaging the components.

Here's another problem I might be having as well.
The manual states:
C81 = Axial 22uF 10v but I pulled 10uF caps from that location on the
CPU PCB.
These were not the original, they were already replaced by someone....
I start another thread for this.
