Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F90R9X is determined by strict equivalence across the following critical parameters:

Resistance value and tolerance must match exactly at 90.9 Ohms ±1%. Power rating must be identical at 0.1W (1/10W). Package format must be 0402 (1005 Metric) to ensure mechanical and electrical compatibility in PCB layouts. Composition type must remain thick film. Temperature coefficient and operating temperature range must be equivalent or superior. Automotive AEC-Q200 rating and anti-sulfur features must be maintained. RoHS3 compliance and MSL 1 rating must be preserved.

The ERJ-U02F90R9X qualifies as a direct substitute because it meets all these criteria while being manufactured by the same supplier, Panasonic Electronic Components.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F90R9X and ERJ-U02F90R9X are active production components from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements. Both components maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, making them suitable for equivalent circuit applications without design modification. The primary distinction lies in the series designation (ERJ-S02 versus ERJ-U02), which reflects internal Panasonic product line organization but does not affect functional performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F90R9X be used as a direct replacement for ERJ-S02F90R9X?

A: Yes. Both components share identical resistance value (90.9 Ohms), tolerance (±1%), power rating (0.1W), package format (0402), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 qualification. No circuit redesign is required.

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

A: No. Both components 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 compliance standards?

A: Yes. Both ERJ-S02F90R9X and ERJ-U02F90R9X are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Both carry AEC-Q200 automotive rating and anti-sulfur coating.

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

A: The series designation reflects Panasonic's internal product line categorization. From an engineering perspective, both series offer identical electrical performance and specifications for this 90.9 Ohm 1% 0402 resistor configuration.

Q: Are these parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification, anti-sulfur coating, and operate across the -55°C ~ 155°C temperature range required for automotive environments.
