Hi donna, You'll need to determine if the older charger has the same wattage output. That is, is it a 60 watt or 85 watt unit. Typically, if your computer uses the 85 watt power adapter, then as long as the other is the same wattage or less, you'll be fine. The problems occur if you go the opposite direction, that is, if your MBP uses the 60 watt power adapter, you cannot use the 85 watt one as it can burn out components in the charging system. The wattage rating is labeled on the charger itself as well as you should be able to find this info on the web or within your electronic User's Guide.
HTH. Later...
