IP03 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 3 vs 5). IP03 is rated for no protection and spraying water (up to 60°), while IP25 provides > 12.5 mm — finger 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.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 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.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 5.

The exact difference (IP03 vs IP25)
Solid protection
IP03
Level 0 — No Protection
IP25
Level 2 — > 12.5 mm — Finger
IP03 provides "No Protection" (level 0), while IP25 provides "> 12.5 mm — Finger" (level 2). IP25 is 2 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP25 provides 2 levels more liquid protection.

Recommendation
IP25 offers higher overall protection than IP03. Choose IP25 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
