Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F43R0X is determined by strict equivalence across the following critical parameters:

• Resistance value: 43 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 construction

The ERJ-U02F43R0X meets all these criteria and qualifies as a direct electrical and mechanical equivalent. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance characteristics, thermal behavior, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F43R0X and ERJ-U02F43R0X are active production components manufactured by Panasonic Electronic Components. The ERJ-U02F43R0X offers significantly higher inventory availability (20,911 units in stock versus 642 units), making it the preferred selection for high-volume applications or extended lead-time mitigation. Both parts carry identical ROHS3 compliance, AEC-Q200 automotive qualification, and REACH unaffected status. Selection between these parts should be based on supply chain requirements and inventory availability rather than electrical or mechanical performance considerations, as all specified parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02F43R0X be used as a direct replacement for the ERJ-S02F43R0X?
