You might want to be limping (if you don't want to raise) any pocket pair, any AXs, KXs down to K9s, suited connectors down to 87s or so, suited one gappers down to 97s, unsuited connectors down to JT, and occasionally other hands. You can limp in with a much wider range given reasonably deep stacks and little chance of a raise after you.
Even that is situational though depending on how many limped, how sticky they are when they limp, how wide their limping ranges are, what your exact position is, how likely villains after you are to call and so on. If nobody behind you is likely to raise then raise something like AQ+/TT+ with a few weaker hands.
