Substitute Part Grouping Explanation

The ERJ-U02F5100X qualifies as a direct substitute for the ERJ-S02F5100X based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 510 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height - Seated (Max): 0.016" (0.40mm)
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

The difference between ERJ-S02 and ERJ-U02 series represents alternative product lines within Panasonic's thick film resistor portfolio, both meeting identical specifications for this 510 Ohm 1% 1/10W configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F5100X and ERJ-U02F5100X are active production parts from Panasonic Electronic Components with identical electrical specifications and mechanical dimensions. Selection between these parts may be based on inventory availability, supply chain considerations, or procurement preferences, as both meet ROHS3 compliance and automotive AEC-Q200 qualification requirements. The ERJ-U02F5100X currently maintains higher inventory levels (38,658 units) compared to the ERJ-S02F5100X (754 units), which may influence lead time and availability for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F5100X be used as a direct replacement for ERJ-S02F5100X?

A: Yes. Both parts share identical electrical parameters (510 Ohms ±1%, 0.1W), mechanical dimensions (0402 package, 1.00mm x 0.50mm), temperature characteristics (±200ppm/°C, -55°C to 155°C), and compliance ratings (AEC-Q200, ROHS3, MSL 1). The difference between ERJ-S02 and ERJ-U02 series does not affect functional compatibility.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 0402 (1005 Metric) package with identical physical 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 remain unchanged.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both ERJ-S02F5100X and ERJ-U02F5100X carry AEC-Q200 automotive qualification and are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), suitable for automotive and high-reliability applications.

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

A: Both series are Panasonic thick film resistor product lines offering identical specifications for this 510 Ohm 1% 1/10W configuration. The series designation reflects alternative product lines within Panasonic's portfolio rather than functional or electrical differences.

Q: Which part should be selected based on availability?

A: Selection may be based on current inventory and supply chain requirements. The ERJ-U02F5100X maintains significantly higher stock levels, which may provide shorter lead times for high-volume orders.
