Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S03J3R0V is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 3 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 format: 0603 (1608 Metric)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Height - Seated (Max): 0.022" (0.55mm)
• Number of terminations: 2

Functional & Compliance Requirements:

• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ERJ-U03J3R0V qualifies as a direct substitute based on identical electrical, mechanical, and compliance parameters. The primary distinction is the series designation (ERJ-U03 versus ERJ-S03) and packaging configuration (Tape & Reel versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S03J3R0V and ERJ-U03J3R0V are active production parts manufactured by Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

ERJ-S03J3R0V is appropriate for applications where standard packaging is specified or preferred, with current inventory of 1119 pieces supporting immediate availability.

ERJ-U03J3R0V is appropriate for high-volume production environments requiring Tape & Reel (TR) packaging format, with significantly higher inventory availability of 6037 pieces supporting sustained supply chain operations.

Both parts maintain full compliance with ROHS3, REACH Unaffected status, and AEC-Q200 automotive qualification. The identical electrical performance, temperature characteristics, and physical dimensions ensure direct functional interchangeability within circuit designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U03J3R0V replace ERJ-S03J3R0V in circuit applications?

A: Yes. Both parts are electrically and mechanically identical with 3 Ohm ±5% resistance, 0.1W power rating, 0603 package format, and identical operating temperature ranges. The primary difference is packaging configuration (Tape & Reel versus standard).

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

A: The series designation reflects the packaging configuration. ERJ-S03 uses standard packaging, while ERJ-U03 uses Tape & Reel (TR) format. Electrical and mechanical specifications are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ERJ-S03J3R0V and ERJ-U03J3R0V carry AEC-Q200 automotive qualification and anti-sulfur properties, meeting automotive reliability requirements.

Q: What is the significance of the 0603 package designation?

A: The 0603 package (1608 Metric) is a standard surface-mount resistor format measuring 0.063" L x 0.031" W (1.60mm x 0.80mm). Both substitute parts use this identical package format, ensuring PCB footprint compatibility.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical environmental and regulatory certifications.

Q: Which part should be selected for high-volume manufacturing?

A: ERJ-U03J3R0V with Tape & Reel packaging is standard for high-volume production environments, with higher inventory availability (6037 pieces) supporting sustained manufacturing operations.

Q: Is the temperature coefficient identical between both parts?

A: Yes. Both parts specify -100 / +600 ppm/°C temperature coefficient and -55°C ~ 155°C operating temperature range.
