Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F2490X is determined by strict equivalence across the following critical parameters:

• Resistance value: 249 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur feature requirement
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The ERJ-U02F2490X qualifies as a direct substitute because it maintains identical electrical characteristics, mechanical dimensions, environmental ratings, and compliance certifications as the primary part.
