IP63 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP63 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 3 vs 8). IP63 is rated for dust-tight and spraying water (up to 60°), while IPX8 provides no protection and continuous immersion (manufacturer-specified).
The IP63 classification guarantees dust-tight (no ingress of dust) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 3.
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 (IP63 vs IPX8)
Solid protection
IP63
Level 6 — Dust-Tight
IPX8
Level 0 — No Protection
IP63 provides "Dust-Tight" (level 6), while IPX8 provides "No Protection" (level 0). IP63 is 6 levels higher.
Liquid protection
IP63
Level 3 — Spraying Water (up to 60°)
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP63 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
IP63 offers higher overall protection than IPX8. Choose IP63 for harsher environments; IPX8 may suffice for milder conditions and can be more cost-effective.
