Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J1R1X is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (1.1 Ohms), tolerance (±5%), and power rating (0.1W) must be identical
• Package Dimensions: 0402 (1005 Metric) form factor with matching physical dimensions (0.039" L x 0.020" W, 0.016" max height)
• Material Composition: Thick film construction
• Environmental Features: Anti-sulfur coating and AEC-Q200 automotive qualification
• Temperature Performance: Operating range -55°C ~ 155°C and temperature coefficient -100 / +600 ppm/°C
• Compliance: ROHS3 compliance and MSL 1 rating

The ERJ-U02J1R1X qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is the packaging configuration (Tape & Reel versus standard packaging) and the base series designation (ERJ-U02 versus ERJ-S02).

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02J1R1X and ERJ-U02J1R1X are active production components from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations rather than functional performance.

ERJ-S02J1R1X is appropriate for applications requiring standard packaging configuration with current inventory of 969 pieces available.

ERJ-U02J1R1X is appropriate for high-volume production environments utilizing automated tape and reel handling systems, with higher inventory availability of 11,125 pieces.

Both parts maintain full compliance with ROHS3 regulations, REACH requirements, and automotive AEC-Q200 qualification standards. The operating temperature range of -55°C ~ 155°C and temperature coefficient of -100 / +600 ppm/°C are identical across both part numbers, ensuring equivalent performance in automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J1R1X be used as a direct replacement for ERJ-S02J1R1X?

A: Yes. The ERJ-U02J1R1X is electrically and mechanically equivalent to the ERJ-S02J1R1X. Both parts have identical resistance (1.1 Ohms), tolerance (±5%), power rating (0.1W), package dimensions (0402), and compliance certifications. The primary difference is packaging format: ERJ-U02J1R1X is supplied in Tape & Reel configuration while ERJ-S02J1R1X uses standard packaging.

Q: What is the difference between ERJ-S02 and ERJ-U02 series designations?

A: The series designation reflects the packaging configuration. ERJ-S02 indicates standard packaging, while ERJ-U02 indicates Tape & Reel (TR) packaging. The electrical and mechanical specifications remain identical between series variants of the same base resistance value.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ERJ-S02J1R1X and ERJ-U02J1R1X carry AEC-Q200 automotive qualification and anti-sulfur coating, making them suitable for automotive and harsh environment applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What is the significance of the 0402 package designation?

A: The 0402 package designation refers to the physical dimensions in metric units (1005 Metric). This is a standard surface-mount resistor package measuring 1.00mm length by 0.50mm width with a maximum seated height of 0.40mm. Both substitute parts use identical 0402 packaging, ensuring PCB footprint compatibility.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (standard versus Tape & Reel) does not affect electrical performance. Both configurations deliver identical resistance, tolerance, power rating, and temperature characteristics. Packaging selection is based on manufacturing and assembly process requirements.

Q: Are there any compliance differences between the two parts?

A: No. Both ERJ-S02J1R1X and ERJ-U02J1R1X maintain identical compliance status: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited moisture sensitivity level). Regulatory and environmental compliance is equivalent across both part numbers.
