Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3ARW242V is determined by strict equivalence across the following parameters:

• Resistance value: 2.4 kOhms
• Tolerance specification: ±0.05%
• Power rating: 0.1W (1/10W)
• Thin film composition
• Package format: 0603 (1608 Metric)
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 compliance
• RoHS3 compliance status
• MSL rating: 1 (Unlimited)

The substitute part RG1608N-242-W-T1 from Susumu meets all these criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ERA-3ARW242V and RG1608N-242-W-T1 are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. The electrical parameters, mechanical dimensions, and environmental ratings are equivalent. The Susumu RG1608N-242-W-T1 includes anti-sulfur treatment as an additional feature and maintains a slightly lower maximum seated height of 0.020" (0.50mm) compared to 0.022" (0.55mm) for the Panasonic part. Both components are suitable for direct substitution in automotive applications requiring thin film precision resistors with ±0.05% tolerance and 0.1W power dissipation capability.

Frequently Asked Questions (FAQ)

Q: What determines if RG1608N-242-W-T1 can substitute for ERA-3ARW242V?

A: Direct substitution is valid when resistance value, tolerance, power rating, package format, temperature coefficient, operating temperature range, and automotive compliance ratings are identical. The RG1608N-242-W-T1 meets all these criteria.

Q: Are there any mechanical compatibility concerns between these parts?

A: Both parts use the 0603 (1608 Metric) package with identical length and width dimensions of 0.063" x 0.031" (1.60mm x 0.80mm). The Susumu part has a maximum seated height of 0.020" (0.50mm) versus 0.022" (0.55mm) for the Panasonic part, which presents no compatibility issues for standard PCB assembly.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERA-3ARW242V and RG1608N-242-W-T1 carry AEC-Q200 automotive qualification and ROHS3 compliance certification.

Q: What is the difference in packaging between these parts?

A: The ERA-3ARW242V is supplied in Cut Tape (CT) & Digi-Reel format, while the RG1608N-242-W-T1 is supplied in Tape & Reel (TR) format. Both packaging formats are standard for automated assembly processes.

Q: Are the temperature and moisture specifications identical?

A: Yes. Both parts operate across -55°C to 155°C with a temperature coefficient of ±10ppm/°C and carry MSL rating 1 (Unlimited moisture sensitivity level).
