They sound alike but they're not. One is easier to get; the other lasts a lot longer.

New Jersey landlords run into two similar-sounding terms: lead-safe and lead-free. They're not interchangeable, and the difference affects how often you have to re-inspect.
A lead-safe certificate means that at the time of inspection, no lead hazard was present. It doesn't claim the unit has zero lead paint anywhere; it says the paint is intact and not creating a dust or chip hazard. This is the common certificate, and it's valid for three years or until the next tenant turnover.
A lead-free certificate is a stronger statement: there's no lead-based paint in the unit at all. Earning it usually requires XRF testing, which reads the lead content of the paint itself. Because there's nothing left to deteriorate, a lead-free determination lasts far longer and can take the unit out of the periodic inspection cycle.
For most owners, a lead-safe certificate is the practical choice: it's cheaper and it satisfies the law. Lead-free is worth considering if you own an older property you plan to hold for years and want to stop re-inspecting it every cycle. It costs more up front but can pay off over time.
Not sure which makes sense for your property? A certified inspector can look at the unit and tell you whether lead-free is even achievable before you pay for the extra testing.
