• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: -100 / +600 ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height - Seated (Max): 0.016" (0.40mm)
• Number of terminations: 2

Compliance & Features (Must Match Exactly):

• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ERJ-U02J1R8X meets all substitution criteria and is classified as a direct equivalent.

Engineering Selection Recommendations

Both the ERJ-S02J1R8X and ERJ-U02J1R8X are active production components manufactured by Panasonic Electronic Components with full compliance to ROHS3 and AEC-Q200 automotive qualification standards. The parts are functionally and mechanically interchangeable across all specified parameters.

Selection between these components should be based on inventory availability and supply chain requirements. The ERJ-U02J1R8X currently maintains higher stock levels (10,957 units) compared to the ERJ-S02J1R8X (1,049 units), making it suitable for high-volume production requirements. Both components satisfy identical electrical performance, thermal characteristics, and environmental compliance requirements for automotive applications operating within the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02J1R8X be used as a direct replacement for the ERJ-S02J1R8X in automotive applications?

A: Yes. Both components are manufactured by Panasonic Electronic Components with identical electrical specifications (1.8 Ohms ±5%, 0.1W), mechanical dimensions (0402 package), and automotive qualifications (AEC-Q200). They are functionally equivalent for all circuit applications.

Q: Are there any differences in the physical package between these two resistors?

A: No. Both components use the 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the ERJ-S02J1R8X and ERJ-U02J1R8X are ROHS3 compliant, AEC-Q200 qualified, feature anti-sulfur construction, and maintain Moisture Sensitivity Level 1 (Unlimited). They meet identical environmental and automotive standards.

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

A: The series designation (ERJ-S02 versus ERJ-U02) indicates different product lines within Panasonic's resistor portfolio. However, for the 1.8 Ohm 0.1W 0402 specification, both series deliver identical electrical and mechanical performance characteristics.

Q: Can these components be used interchangeably in tape and reel packaging?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging format, which is standard for automated PCB assembly processes. The packaging format is identical between the two parts.

Q: What is the temperature coefficient specification, and does it differ between the two parts?

A: The temperature coefficient for both components is -100 / +600 ppm/°C, indicating identical thermal stability characteristics. Both parts maintain the same resistance variation across the operating temperature range of -55°C to 155°C.
