Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S03F6R80V is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (6.8 Ohms), tolerance (±1%), and power rating (0.1W) must be identical
• Package Compatibility: 0603 (1608 Metric) package ensures mechanical and thermal compatibility with existing PCB layouts
• Composition and Features: Thick film construction with anti-sulfur coating and AEC-Q200 automotive qualification must be maintained
• Environmental Performance: Temperature coefficient (-100 / +600 ppm/°C) and operating temperature range (-55°C ~ 155°C) must match
• Compliance Standards: RoHS3 compliance and MSL 1 rating must be preserved

The ERJ-U03F6R80V meets all these criteria and is classified as a direct substitute for the ERJ-S03F6R80V.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S03F6R80V and ERJ-U03F6R80V are active production parts manufactured by Panasonic Electronic Components with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

The ERJ-S03F6R80V (ERJ-S03 series) is suitable for applications where the primary part number is specified in design documentation. The ERJ-U03F6R80V (ERJ-U03 series) serves as a direct functional equivalent when the primary part is unavailable or when alternative sourcing is required.

Both parts maintain full compliance with automotive AEC-Q200 qualification, RoHS3 directives, and REACH regulations. The identical MSL 1 rating indicates both parts have unlimited shelf life under standard storage conditions. PCB layout and thermal design considerations remain unchanged when substituting between these parts due to matching package dimensions and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U03F6R80V be used as a direct replacement for ERJ-S03F6R80V in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (6.8 Ohms ±1%, 0.1W), package dimensions (0603), and operating temperature range (-55°C ~ 155°C). They are functionally equivalent for automotive circuit applications.

Q: Are there any differences in PCB layout or footprint between these two parts?

A: No. Both parts use the 0603 (1608 Metric) package with identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.022" / 0.55mm). PCB footprints are interchangeable.

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

A: Yes. Both the ERJ-S03F6R80V and ERJ-U03F6R80V carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under standard storage conditions with no special moisture control requirements.

Q: What is the difference between the ERJ-S03 and ERJ-U03 series designations?

A: The series designation (S03 versus U03) identifies different product lines within Panasonic's resistor portfolio. Both series share identical electrical and mechanical specifications for this 6.8 Ohm 1% 0.1W 0603 package configuration.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ERJ-S03F6R80V and ERJ-U03F6R80V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

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

A: Yes. Both parts have identical operating temperature ranges (-55°C ~ 155°C) and temperature coefficients (-100 / +600 ppm/°C), ensuring equivalent performance in high-temperature environments.
