Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-3RQJ2R4V is determined by matching the following critical parameters:

• Resistance value: 2.4 Ohms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Package format: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The RC0603JR-072R4L from YAGEO meets all these parameters and qualifies as a direct electrical and mechanical substitute. Both parts share identical resistance, tolerance, power rating, package dimensions, thermal characteristics, and environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-3RQJ2R4V and RC0603JR-072R4L are active production components with full RoHS3 compliance and REACH unaffected status. The ERJ-3RQJ2R4V carries AEC-Q200 automotive qualification and current sense designation specific to Panasonic's automotive product line. The RC0603JR-072R4L from YAGEO is specified with moisture resistant characteristics. Selection between these parts should be based on supply chain availability, lead time requirements, and specific application qualification requirements. Both components are suitable for applications requiring 2.4 Ohm thick film resistors in 0603 package format with ±5% tolerance and 0.1W power rating across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-072R4L replace ERJ-3RQJ2R4V in automotive applications?

A: Both parts match all critical electrical and mechanical parameters including resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. However, the ERJ-3RQJ2R4V carries explicit AEC-Q200 automotive qualification. Application-specific automotive qualification requirements should be verified before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are 0603 (1608 Metric) package format with identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts.

Q: What is the difference in features between these two parts?

A: The ERJ-3RQJ2R4V is specified with AEC-Q200 automotive qualification and current sense functionality. The RC0603JR-072R4L is specified with moisture resistant characteristics. Both parts have MSL rating of 1 (Unlimited) and are ROHS3 compliant.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both the ERJ-3RQJ2R4V and RC0603JR-072R4L have a temperature coefficient of ±200ppm/°C and operate across the identical temperature range of -55°C to 155°C.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory or compliance barriers exist for substitution from a materials and environmental standpoint.
