Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S02J4R7X is based on electrical and mechanical parameter equivalence. The substitute part must satisfy all of the following criteria:

• Resistance value: 4.7 Ohms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• Temperature coefficient: -100 / +600 ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting these specifications are electrically and mechanically interchangeable with the ERJ-S02J4R7X and can be used in direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U02J4R7X is a direct equivalent substitute for the ERJ-S02J4R7X. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications, mechanical dimensions, and compliance certifications. Both parts maintain active production status and are ROHS3 compliant with REACH unaffected designation. The ERJ-U02J4R7X is available in higher inventory quantity (6456 pieces) compared to the ERJ-S02J4R7X (838 pieces), making it suitable for applications where supply availability is a consideration. Selection between these parts should be based on inventory availability and procurement lead time requirements, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02J4R7X be used as a direct replacement for the ERJ-S02J4R7X?

A: Yes. The ERJ-U02J4R7X is electrically and mechanically equivalent to the ERJ-S02J4R7X. All critical parameters including resistance value, tolerance, power rating, package dimensions, operating temperature range, and automotive AEC-Q200 qualification are identical.

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

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable on printed circuit boards.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the ERJ-S02J4R7X and ERJ-U02J4R7X are ROHS3 compliant, REACH unaffected, and carry automotive AEC-Q200 qualification with anti-sulfur properties. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the difference between the ERJ-S02 and ERJ-U02 series designations?

A: The series designation (ERJ-S02 versus ERJ-U02) indicates different product lines within Panasonic's resistor portfolio. However, for the 4.7 Ohm, 1/10W, 0402 package configuration, both series provide identical electrical and mechanical specifications.

Q: Are these parts suitable for automotive applications?

A: Yes. Both parts carry automotive AEC-Q200 qualification and feature anti-sulfur properties, making them suitable for automotive and harsh environment applications requiring high reliability standards.

Q: What is the temperature coefficient specification and why is it important?

A: The temperature coefficient is -100 / +600 ppm/°C for both parts. This specification indicates the maximum change in resistance value per degree Celsius across the operating temperature range of -55°C to 155°C. This parameter is critical for applications requiring stable resistance performance across wide temperature variations.
