Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - Same Temperature Coefficient):

The RG2012N-3570-B-T5 and RG2012N-3570-W series parts maintain the ±10ppm/°C temperature coefficient of the original RG2012N-3570-C-T5 while offering improved tolerance specifications. These parts are classified as active products and are suitable for direct substitution in applications where the original temperature coefficient performance is required.

Enhanced Performance Substitutes (Improved Temperature Coefficient):

The RG2012V-3570 series parts provide superior temperature stability with ±5ppm/°C coefficient, representing a 50% improvement over the original specification. These parts are active products with higher inventory availability. The RG2012V-3570-P-T1 offers the highest precision at ±0.02% tolerance, while RG2012V-3570-B-T5 and RG2012V-3570-W series provide ±0.1% and ±0.05% tolerance options respectively.

Selection Criteria:

All substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur construction, ROHS3 compliance, and identical package dimensions. Selection between substitutes depends on application requirements for tolerance precision and temperature stability. Active product status ensures continued availability and supply chain reliability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-3570 series parts replace RG2012N-3570-C-T5 in existing designs?

A: Yes. The RG2012V-3570 series maintains all critical electrical and mechanical parameters including resistance value, power rating, package dimensions, and automotive qualification. The improved temperature coefficient (±5ppm/°C versus ±10ppm/°C) represents enhanced performance without compatibility issues.

Q: What is the difference between RG2012N and RG2012V designations?

A: The RG2012N series maintains a temperature coefficient of ±10ppm/°C, while the RG2012V series provides improved stability at ±5ppm/°C. Both series are thin film, anti-sulfur, AEC-Q200 qualified resistors in 0805 package.
