FACT is, either condenser (if functional/not defective) will work and allow the ignition system to produce spark.
The unknown is if the capacitance values may differ a bit. If they do, the points may pit excessively over time, but for the short term, swapping one condenser for the other will NOT cause total loss of spark.
Is your original condenser known to be "bad", or is it missing entirely? Point being a good, working original condenser is most likely more reliable than what you are going to find on the market today.
