Substitute Part Grouping Explanation

Substitution of the ERJ-S03J1R5V is determined by strict equivalence across the following critical parameters:

• Resistance Value: 1.5 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Anti-Sulfur, Automotive AEC-Q200 (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Temperature Coefficient: -100 / +600 ppm/°C (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The ERJ-U03J1R5V meets all substitution criteria and is classified as a direct equivalent part.
