Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3ARW433V is determined by strict equivalence across the following parameters:

• Resistance value: 43 kOhms
• Tolerance: ±0.05%
• Power rating: 0.1W
• Package format: 0603 (1608 Metric)
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• Composition: Thin Film
• RoHS compliance: ROHS3

The substitute part RG1608N-433-W-T1 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-3ARW433V and RG1608N-433-W-T1 are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability and application-specific requirements. The RG1608N-433-W-T1 includes anti-sulfur feature coating, which provides additional environmental protection in corrosive atmospheres. The seated height difference of 0.002" (0.05mm) is within typical PCB assembly tolerances and does not affect functional compatibility in standard automotive circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-433-W-T1 replace ERA-3ARW433V in automotive applications?

A: Yes. Both parts meet identical electrical specifications (43 kOhms ±0.05%, 0.1W, ±10ppm/°C), operate across the same temperature range (-55°C ~ 155°C), and carry AEC-Q200 automotive qualification. Package dimensions are equivalent at 0603 (1608 Metric).

Q: What is the significance of the anti-sulfur feature on the Susumu part?

A: The anti-sulfur coating on RG1608N-433-W-T1 provides enhanced resistance to sulfur-containing environments, which may be present in certain automotive or industrial settings. This is an additional feature not specified for the Panasonic part.

Q: Are there dimensional compatibility concerns?

A: The seated height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly processes and does not affect circuit board layout or component placement.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both ERA-3ARW433V and RG1608N-433-W-T1 are ROHS3 compliant and REACH unaffected, meeting current automotive and industrial environmental standards.
