Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F1003X is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 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: Present
• RoHS compliance: ROHS3 Compliant

The ERJ-U02F1003X meets all substitution criteria. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance, thermal characteristics, and environmental ratings. The primary distinction is the series designation (ERJ-S02 versus ERJ-U02), which reflects different manufacturing process lines within Panasonic's automotive resistor portfolio while maintaining full specification equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F1003X and ERJ-U02F1003X are qualified for direct substitution in automotive applications. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences. Both components maintain active production status and carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and environmental ratings. The ERJ-S02F1003X currently has higher inventory availability (9776 units) compared to the ERJ-U02F1003X (5862 units). For applications requiring long-term supply assurance, either part provides equivalent reliability and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1003X be used as a direct replacement for ERJ-S02F1003X in automotive circuits?
