They're pin-compatible, but not electrically equivalent due to a different gas fill. Dance (Electronic Counting Circuits) specifically cautions against direct substitution as it leads to significantly reduced life of the EZ10A. So, you're probably OK for a short test to see if the tube works, but not to run more extensively. Since it's over-current that would be the concern, I'm guessing that you could make the EZ10A happy long term by increasing the anode resistor, but I can't lay my hands on the relevant numbers to substantiate that at the moment.
