IP03 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 3 vs 5). IP03 is rated for no protection and spraying water (up to 60°), while IP35 provides > 2.5 mm — tool / wire and water jets (6.3 mm nozzle).
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.
Built to withstand protection against solid objects larger than 2.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.

The exact difference (IP03 vs IP35)
Solid protection
IP03
Level 0 — No Protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP03 provides "No Protection" (level 0), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP35 is 3 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP35 provides 2 levels more liquid protection.

Recommendation
IP35 offers higher overall protection than IP03. Choose IP35 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
