IP33 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP33 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 3 vs 8). IP33 is rated for > 2.5 mm — tool / wire and spraying water (up to 60°), while IPX8 provides no protection and continuous immersion (manufacturer-specified).
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.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP33 vs IPX8)
Solid protection
IP33
Level 3 — > 2.5 mm — Tool / Wire
IPX8
Level 0 — No Protection
IP33 provides "> 2.5 mm — Tool / Wire" (level 3), while IPX8 provides "No Protection" (level 0). IP33 is 3 levels higher.
Liquid protection
IP33
Level 3 — Spraying Water (up to 60°)
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP33 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IPX8 provides 5 levels more liquid protection.

Recommendation
IPX8 offers higher overall protection than IP33. Choose IPX8 for harsher environments; IP33 may suffice for milder conditions and can be more cost-effective.
