What is the difference between an NGK BPR-6ES spark plug and a NGK BP-6ES spark plug?

I need to replace a spark plug that is a NGK BPR_6ES and the only replacement i have is a NGK BP-6ES.Will it be suitable for a small honda motor on a davey pump.

Structurally they are the same the only difference is the BPR 6ES has an internal resistor.
The BP 6ES should work better then the BPR 6ES on a small engine.
