Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F4990X is determined by strict equivalence across the following critical parameters:

• Resistance value: 499 Ohms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• Temperature coefficient: ±200ppm/°C
• Compliance: ROHS3, AEC-Q200

The ERJ-U02F4990X qualifies as a direct substitute because it maintains identical electrical specifications, mechanical dimensions, and automotive qualification ratings. The primary difference lies in the base product series designation (ERJ-U02 versus ERJ-S02), which reflects manufacturing line variation within Panasonic's product portfolio while preserving all functional and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F4990X and ERJ-U02F4990X are active production components manufactured by Panasonic Electronic Components with identical ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on inventory availability and supply chain requirements, as they are functionally and mechanically interchangeable. The ERJ-U02F4990X currently maintains higher inventory levels (10,566 units) compared to the ERJ-S02F4990X (770 units), making it suitable for high-volume applications or long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F4990X be used as a direct replacement for ERJ-S02F4990X in automotive applications?

A: Yes. Both parts carry identical AEC-Q200 automotive qualification, operating temperature range (-55°C ~ 155°C), and anti-sulfur coating. They are mechanically and electrically interchangeable in all automotive circuit designs.

Q: Are there any differences in package dimensions between these two parts?
