Substitute Part Grouping Explanation
The ERJ-U02F1201X qualifies as a direct substitute for the ERJ-S02F1201X based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:
- Resistance value: 1.2 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
- AEC-Q200 automotive qualification
- Anti-sulfur feature
- RoHS3 compliance
- MSL rating: 1
The primary difference between these parts is the series designation (ERJ-S02 versus ERJ-U02), which reflects different manufacturing series within Panasonic's product line. Both series maintain identical performance specifications and compliance certifications.
