Substitute Part Grouping Explanation

Substitution of the ERJ-S02J2R7X is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 2.7 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: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Maximum seated height: 0.016" (0.40mm)
• Termination count: 2

Compliance & Construction:

• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1

The ERJ-U02J2R7X qualifies as a direct substitute because it maintains identical electrical performance, mechanical compatibility, and regulatory compliance across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02J2R7X and ERJ-U02J2R7X are active production components manufactured by Panasonic Electronic Components. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

ERJ-S02J2R7X is suitable for applications where the ERJ-S02 series designation is specified or preferred. Current inventory of 1122 pieces supports immediate procurement.

ERJ-U02J2R7X is suitable as a direct substitute when supply of the ERJ-S02J2R7X is constrained. The ERJ-U02 series maintains identical electrical and mechanical specifications. Current inventory of 10612 pieces provides extended availability.

Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH requirements. Selection does not impact circuit performance, thermal behavior, or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J2R7X replace ERJ-S02J2R7X in automotive applications?

A: Yes. Both parts are AEC-Q200 rated with identical electrical specifications (2.7 Ohms ±5%, 0.1W), mechanical dimensions (0402 package), and operating temperature range (-55°C ~ 155°C). The substitution maintains full compliance with automotive qualification requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 0.039" L x 0.020" W (1.00mm x 0.50mm) with a maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable in 0402 (1005 Metric) footprints.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both ERJ-S02J2R7X and ERJ-U02J2R7X have a temperature coefficient of -100 / +600 ppm/°C and operate across the identical temperature range of -55°C ~ 155°C.

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

A: The series designation indicates different product lines within Panasonic's thick film resistor portfolio. Both series share identical electrical performance, mechanical compatibility, and compliance certifications for this 2.7 Ohm 0402 package specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ERJ-S02J2R7X and ERJ-U02J2R7X are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions, termination count, and electrical specifications ensure direct interchangeability on PCB assemblies designed for 0402 (1005 Metric) chip resistors with 2.7 Ohm ±5% tolerance.
