Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F51R0X is determined by strict equivalence across the following critical parameters:

• Resistance value: 51 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package format: 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-U02F51R0X qualifies as a direct equivalent substitute because it matches all specified electrical, mechanical, and environmental parameters. Both parts are manufactured by Panasonic Electronic Components and share identical functional characteristics within the defined operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F51R0X and ERJ-U02F51R0X are qualified for use in automotive and industrial applications requiring AEC-Q200 certification. Selection between these parts should be based on:
