Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F1803X is determined by strict equivalence across the following critical parameters:

• Resistance value: 180 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur feature requirement
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The ERJ-U02F1803X qualifies as a direct substitute because it matches all specified electrical, mechanical, and environmental parameters. The primary difference is the series designation (ERJ-U02 versus ERJ-S02), which reflects manufacturing process variation within Panasonic's automotive-grade resistor portfolio while maintaining identical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F1803X and ERJ-U02F1803X are active production components manufactured by Panasonic Electronic Components with identical electrical specifications and AEC-Q200 automotive qualification. Selection between these parts should be based on availability and lead time requirements. The ERJ-U02F1803X offers significantly higher inventory availability (27377 units versus 1094 units), making it the preferred choice for applications where supply chain continuity is a priority. Both parts satisfy ROHS3 compliance and REACH unaffected status requirements. PCB layout and assembly processes require no modification when substituting between these parts due to identical package dimensions and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1803X be used as a direct replacement for ERJ-S02F1803X in automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, identical resistance value (180 kOhms ±1%), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). No circuit redesign or validation is required.

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

A: The series designation reflects different manufacturing process lines within Panasonic's automotive-grade resistor portfolio. Both series meet identical electrical and environmental specifications for this 180 kOhms ±1% 0402 package configuration.

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

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

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both ERJ-S02F1803X and ERJ-U02F1803X carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for new designs?

A: Selection should prioritize availability and supply chain stability. The ERJ-U02F1803X provides superior inventory depth (27377 units in stock). Both parts are equally suitable for new automotive designs requiring AEC-Q200 qualification.
