Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F1802X is determined by strict equivalence across the following critical parameters:

• Resistance value: 18 kOhms
• 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
• Automotive qualification: AEC-Q200
• Anti-sulfur feature presence

The ERJ-U02F1802X meets all these criteria and is classified as a direct substitute. The primary difference between the main part and substitute is the series designation (ERJ-S02 versus ERJ-U02), which reflects different manufacturing series within Panasonic's product line while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F1802X and ERJ-U02F1802X are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The ERJ-U02F1802X currently has higher inventory availability (28,595 units) compared to the ERJ-S02F1802X (737 units). Both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating, making them suitable for equivalent circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1802X be used as a direct replacement for ERJ-S02F1802X in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical resistance, tolerance, power rating, package, and operating temperature specifications. The series designation difference (ERJ-S02 versus ERJ-U02) 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 dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are interchangeable.

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

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Temperature coefficient and operating temperature range are identical at ±200ppm/°C and -55°C ~ 155°C respectively.

Q: What is the primary reason to consider the ERJ-U02F1802X as an alternative?

A: Supply chain availability. The ERJ-U02F1802X has significantly higher inventory stock, making it a viable alternative when ERJ-S02F1802X availability is constrained.
