Parameter Comparison

Engineering Selection Recommendations

The ERJ-U02F1R20X is a direct equivalent substitute for the ERJ-S02F1R20X. Both parts are manufactured by Panasonic Electronic Components and share identical electrical, mechanical, and compliance specifications. The parts differ only in their base product series designation (ERJ-S02 versus ERJ-U02), which reflects internal Panasonic product line organization and does not affect functional performance or interchangeability.

Both parts carry active product status and full compliance with ROHS3 and REACH regulations. The AEC-Q200 automotive qualification and anti-sulfur coating are present in both variants, ensuring equivalent reliability in harsh operating environments. The identical moisture sensitivity level (MSL 1) indicates both parts have unlimited shelf life under standard storage conditions.

Selection between these parts should be based on inventory availability and supply chain considerations. The ERJ-U02F1R20X currently has higher inventory (12,143 pieces) compared to the ERJ-S02F1R20X (999 pieces), making it the preferred choice for high-volume production requirements or extended lead-time mitigation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1R20X be used as a direct replacement for ERJ-S02F1R20X in existing designs?

A: Yes. The ERJ-U02F1R20X is a direct equivalent substitute. All electrical parameters (resistance, tolerance, power rating, temperature coefficient), mechanical dimensions (0402 package, 1.00mm x 0.50mm), and compliance certifications (AEC-Q200, ROHS3, REACH) are identical. No circuit redesign or board layout modification is required.

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

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

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S02F1R20X and ERJ-U02F1R20X carry AEC-Q200 automotive qualification and feature anti-sulfur coating for corrosion resistance. Both are suitable for automotive and harsh-environment applications.

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

A: The series designation reflects Panasonic's internal product line organization. From an engineering perspective, both series share identical specifications for this 1.2 Ohm ±1% 0.1W 0402 resistor variant. The difference does not affect performance, reliability, or interchangeability.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S02F1R20X and ERJ-U02F1R20X are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating unlimited shelf life under standard storage conditions. No special moisture control or baking procedures are required prior to assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts have an operating temperature range of -55°C ~ 155°C and identical temperature coefficient of -100 / +600 ppm/°C, ensuring equivalent performance across the full specified temperature range.
