Please make sure to get the correct speed rated part - A higher speed rated chip can generally be used instead of a lower speed, but a lower speed chip should not be used to replace a higher one.
As an example, a Z80B CPU can be used to replace a Z80A CPU, but a Z80A CPU should not be used to replace a Z80B CPU unless you are sure the clock speed is low enough for the Z80A.
