Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F3003X is determined by strict equivalence across the following parameters:

• Resistance value: 300 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur protection: Required
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-U02F3003X qualifies as a direct substitute because it maintains identical electrical specifications, mechanical dimensions, thermal characteristics, and compliance certifications. The difference between ERJ-S02 and ERJ-U02 series represents alternative product lines within Panasonic's automotive resistor portfolio, both meeting the same performance and qualification requirements.
