Frequently Asked Questions (FAQ)

Q: Can the RG2012V-4871-P-T1 be used as a direct replacement for the RG2012N-4871-P-T1 in existing designs?

A: Yes. The RG2012V-4871-P-T1 is electrically and mechanically identical to the RG2012N-4871-P-T1 across all critical parameters including resistance value, tolerance, power rating, package dimensions, and automotive compliance ratings. No design modifications are required.

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

A: The primary difference is product status and temperature coefficient performance. The RG2012N-4871-P-T1 is obsolete with a ±10ppm/°C temperature coefficient. The RG2012V-4871-P-T1 is active with an improved ±5ppm/°C temperature coefficient. Both maintain identical resistance, tolerance, power rating, and package specifications.

Q: Are there any compatibility issues with PCB assembly equipment?

A: No. Both parts use the identical 0805 (2012 Metric) package with matching physical dimensions (0.079" L x 0.049" W, 0.020" max height) and two-terminal configuration. PCB footprints, pick-and-place programming, and reflow profiles require no modification.

Q: Does the improved temperature coefficient of the RG2012V-4871-P-T1 affect circuit performance?

A: The ±5ppm/°C temperature coefficient of the RG2012V-4871-P-T1 provides superior temperature stability compared to the ±10ppm/°C specification of the RG2012N-4871-P-T1. This enhancement does not negatively impact any circuit function and may improve overall circuit performance in temperature-sensitive applications.

Q: What is the packaging difference between the two parts?

A: The RG2012V-4871-P-T1 is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly operations. The main part packaging specification was not provided in the available data.
