IP33 vs IP07
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP33 and IP07 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 3 vs 7). IP33 is rated for > 2.5 mm — tool / wire and spraying water (up to 60°), while IP07 provides no protection and temporary immersion (up to 1 m).
IP33 protects against tools and 2.5 mm objects plus spraying water up to 60° from vertical. A practical rating for indoor equipment subject to light spray or for sheltered outdoor fixtures.
IP07 is an ingress protection code that ensures no protection against solid objects and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 7.

The exact difference (IP33 vs IP07)
Solid protection
IP33
Level 3 — > 2.5 mm — Tool / Wire
IP07
Level 0 — No Protection
IP33 provides "> 2.5 mm — Tool / Wire" (level 3), while IP07 provides "No Protection" (level 0). IP33 is 3 levels higher.
Liquid protection
IP33
Level 3 — Spraying Water (up to 60°)
IP07
Level 7 — Temporary Immersion (up to 1 m)
IP33 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP07 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP07 provides 4 levels more liquid protection.

Recommendation
IP07 offers higher overall protection than IP33. Choose IP07 for harsher environments; IP33 may suffice for milder conditions and can be more cost-effective.
