Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S03J2R2V is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: -100 / +600 ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Specifications:

• Package type: 0603 (1608 Metric)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Maximum seated height: 0.022" (0.55mm)
• Number of terminations: 2

Compliance & Features:

• Composition: Thick Film
• Anti-sulfur construction
• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Differences in manufacturer series designation (ERJ-S03 versus ERJ-U03) do not affect functional equivalence when all electrical, mechanical, and compliance parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U03J2R2V is a direct functional equivalent to the ERJ-S03J2R2V. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

Both parts carry active product status and meet automotive AEC-Q200 qualification requirements. Both are ROHS3 compliant and REACH unaffected. The identical temperature coefficient range (-100 / +600 ppm/°C) and operating temperature range (-55°C ~ 155°C) ensure equivalent thermal performance in circuit applications. The anti-sulfur construction and thick film composition are consistent across both parts.

The ERJ-U03J2R2V series demonstrates higher inventory availability (11040 pieces) compared to the ERJ-S03J2R2V (1041 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U03J2R2V be used as a direct replacement for the ERJ-S03J2R2V in automotive applications?

A: Yes. Both parts meet identical electrical specifications (2.2 Ohms ±5%, 0.1W), mechanical dimensions (0603 package), and automotive AEC-Q200 qualification. They are functionally equivalent for circuit design purposes.

Q: Are there any differences in the 0603 package dimensions between these two parts?

A: No. Both parts have identical physical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts have the same temperature performance characteristics?

A: Yes. Both the ERJ-S03J2R2V and ERJ-U03J2R2V share identical temperature coefficient specifications (-100 / +600 ppm/°C) and operating temperature range (-55°C ~ 155°C).

Q: What is the significance of the different series designations (ERJ-S03 versus ERJ-U03)?

A: The series designation reflects internal Panasonic product line organization but does not indicate functional differences when all electrical and mechanical parameters are identical. Both series meet the same AEC-Q200 automotive qualification standard.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S03J2R2V and ERJ-U03J2R2V are ROHS3 compliant and REACH unaffected.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: Yes. Both parts carry active product status and meet identical compliance certifications. The anti-sulfur construction and thick film composition are consistent across both parts, supporting use in high-reliability automotive and industrial applications.
