Parameter Comparison

Engineering Selection Recommendations

Both the RG2012N-432-W-T1 and ERA-6ARW432V are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations:

RG2012N-432-W-T1 (Susumu): 734 units in stock. Includes anti-sulfur coating feature. Seated height maximum of 0.50mm.

ERA-6ARW432V (Panasonic): 3304 units in stock. Seated height maximum of 0.60mm. Higher inventory availability supports extended production runs and supply chain continuity.

Both components satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). The 0.04mm difference in maximum seated height (0.50mm versus 0.60mm) remains within typical PCB design tolerances for 0805 package components and does not restrict substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARW432V replace RG2012N-432-W-T1 in automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification and identical electrical specifications (4.3 kOhms ±0.05%, 0.125W, ±10ppm/°C temperature coefficient, -55°C ~ 155°C operating range). Direct substitution is supported.

Q: Are there physical compatibility concerns between these parts?

A: Both components use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" L x 0.049" W). The seated height difference (0.50mm maximum for RG2012N-432-W-T1 versus 0.60mm maximum for ERA-6ARW432V) is within standard PCB design clearances for this package class and does not restrict board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Compliance profiles are identical.

Q: What is the tolerance specification for these resistors?

A: Both the RG2012N-432-W-T1 and ERA-6ARW432V are specified at ±0.05% tolerance, representing thin film precision resistor performance suitable for high-accuracy circuit applications.

Q: Are these components suitable for high-temperature environments?

A: Yes. Both components operate across the -55°C ~ 155°C temperature range with a temperature coefficient of ±10ppm/°C, supporting automotive and industrial applications requiring extended thermal performance.

Q: What is the difference between the anti-sulfur coating on the RG2012N-432-W-T1?

A: The RG2012N-432-W-T1 includes anti-sulfur coating as a specified feature. The ERA-6ARW432V does not list this feature in provided specifications. In applications where sulfur resistance is a design requirement, the RG2012N-432-W-T1 should be selected. For general-purpose applications, both parts are functionally equivalent.
