Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S03J2R7V and ERJ-U03J2R7V are active production parts manufactured by Panasonic Electronic Components with identical electrical and mechanical specifications. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for automotive and industrial applications. The parts are functionally interchangeable in all circuit applications requiring a 2.7 Ohm ±5% 0.1W thick film resistor in 0603 package format. Selection between these parts may be based on inventory availability, supply chain considerations, or procurement requirements, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U03J2R7V be used as a direct replacement for the ERJ-S03J2R7V?

A: Yes. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications (2.7 Ohms ±5%, 0.1W), mechanical dimensions (0603 package, 1.60mm x 0.80mm), composition (thick film), and compliance certifications (AEC-Q200, ROHS3). They are functionally equivalent.

Q: Are there differences in the package or physical dimensions?

A: No. Both parts use the 0603 (1608 Metric) package with identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). Both are supplied in Tape & Reel (TR) packaging.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S03J2R7V and ERJ-U03J2R7V carry AEC-Q200 automotive qualification and feature anti-sulfur properties, making them suitable for automotive applications.

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

A: The ERJ-S03 and ERJ-U03 are different product series within Panasonic's resistor portfolio. For the 2.7 Ohm ±5% 0.1W 0603 specification, both series produce parts with identical electrical and mechanical characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S03J2R7V and ERJ-U03J2R7V are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The identical 0603 package dimensions, termination configuration (2 terminations), and electrical specifications allow direct substitution in PCB designs without layout or assembly modifications.
