IP03 vs IP38
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP38 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 3 vs 8). IP03 is rated for no protection and spraying water (up to 60°), while IP38 provides > 2.5 mm — tool / wire and continuous immersion (manufacturer-specified).
Designed for environments requiring no protection against solid objects and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects., IP03 is an IEC 60529 code combining solid level 0 with liquid level 3.
IP38 provides protection against solid objects larger than 2.5 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 8.

The exact difference (IP03 vs IP38)
Solid protection
IP03
Level 0 — No Protection
IP38
Level 3 — > 2.5 mm — Tool / Wire
IP03 provides "No Protection" (level 0), while IP38 provides "> 2.5 mm — Tool / Wire" (level 3). IP38 is 3 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP38
Level 8 — Continuous Immersion (manufacturer-specified)
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP38 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP38 provides 5 levels more liquid protection.

Recommendation
IP38 offers higher overall protection than IP03. Choose IP38 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
