Substitute Part Grouping Explanation

Substitution of the ERJ-S02J3R3X is permissible with parts that maintain identical electrical specifications and mechanical compatibility. The critical parameters governing substitution are:

• Resistance Value: 3.3 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Automotive Qualification: AEC-Q200 (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Temperature Coefficient: -100 / +600 ppm/°C (exact match required)

The ERJ-U02J3R3X qualifies as a direct substitute because it satisfies all electrical and mechanical parameters. Both parts are manufactured by Panasonic Electronic Components, share identical resistance, tolerance, power rating, package configuration, composition, automotive qualification, temperature specifications, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U02J3R3X is a direct functional and mechanical equivalent to the ERJ-S02J3R3X. Both parts are Active products manufactured by Panasonic Electronic Components with identical electrical specifications, package dimensions, and compliance certifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

Both parts satisfy automotive AEC-Q200 qualification requirements and maintain ROHS3 compliance. The identical operating temperature range, temperature coefficient, and moisture sensitivity classification ensure interchangeability in circuit applications. The 0402 (1005 Metric) package configuration and two-termination design are consistent across both parts, permitting direct substitution on printed circuit boards without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02J3R3X replace the ERJ-S02J3R3X in automotive applications?
