Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F91R0X is determined by strict equivalence across the following parameters: resistance value (91 Ohms), tolerance (±1%), power rating (0.1W), package format (0402), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), anti-sulfur feature, and AEC-Q200 automotive rating. The ERJ-U02F91R0X qualifies as a direct substitute because it maintains identical specifications across all these critical parameters while remaining within the same manufacturer's product ecosystem.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F91R0X and ERJ-U02F91R0X are active production components from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: the ERJ-S02F91R0X has 805 units in stock, while the ERJ-U02F91R0X has 6562 units available. Both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating (MSL 1), making either suitable for applications requiring automotive-grade reliability and environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F91R0X be used as a direct replacement for ERJ-S02F91R0X in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical resistance, tolerance, power rating, package format, and operating temperature specifications. The substitution is electrically and mechanically equivalent.

Q: Are there differences in the 0402 package dimensions between these parts?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERJ-S02F91R0X and ERJ-U02F91R0X are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: What is the significance of the anti-sulfur feature on these resistors?

A: The anti-sulfur feature protects the component from corrosion in environments with hydrogen sulfide exposure, which is critical for automotive and industrial applications. Both substitute parts include this feature.

Q: Is there a difference in temperature coefficient between the two parts?

A: No. Both parts have a temperature coefficient of ±200ppm/°C and operate across the same temperature range of -55°C to 155°C.
