Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012N-162-B-T5 is the direct equivalent to RG2012N-162-B-T1. Both parts share identical electrical specifications (1.6 kΩ, ±0.1% tolerance, ±10ppm/°C temperature coefficient) and mechanical dimensions. The primary difference is product status: RG2012N-162-B-T5 is active, whereas the original part is obsolete. This substitution requires no design changes and maintains full compatibility with existing circuit requirements.

ERA-6ARB162V (Panasonic) provides equivalent electrical performance with identical tolerance and temperature coefficient specifications. This part is active and AEC-Q200 qualified. The seated height is 0.60mm compared to 0.50mm for Susumu parts; verify PCB assembly clearance requirements before selection.

Upgraded Alternatives (Improved Tolerance):

RG2012N-162-W-T1, RG2012N-162-W-T5, RG2012V-162-W-T1, RG2012V-162-W-T5, ERA-6ARW162V, and RT0805WRB071K6L all offer ±0.05% tolerance, providing tighter resistance accuracy than the original ±0.1% specification. These parts are suitable for applications requiring improved precision while maintaining all other electrical and thermal characteristics. All are active products with full compliance certifications.

Upgraded Alternatives (Improved Temperature Coefficient):

RG2012V series parts (RG2012V-162-B-T5, RG2012V-162-P-T1, RG2012V-162-W-T1, RG2012V-162-W-T5) feature ±5ppm/°C temperature coefficient, half that of the original part. RG2012V-162-P-T1 additionally offers ±0.02% tolerance. These upgrades are applicable to temperature-sensitive circuits requiring enhanced stability across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-162-B-T1 be replaced with RG2012N-162-B-T5?

A: Yes. RG2012N-162-B-T5 is a direct equivalent with identical electrical specifications (1.6 kΩ, ±0.1%, ±10ppm/°C) and mechanical dimensions (0805 package, 0.50mm seated height). The only difference is product status: RG2012N-162-B-T5 is active while the original is obsolete. No design modifications are required.

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

A: The RG2012V series features a lower temperature coefficient (±5ppm/°C) compared to RG2012N (±10ppm/°C). Both series maintain identical resistance values, tolerance options, power ratings, and package dimensions. RG2012V parts are suitable for applications requiring improved thermal stability.

Q: Can I use ERA-6ARB162V as a direct replacement?

A: ERA-6ARB162V is electrically equivalent (1.6 kΩ, ±0.1%, ±10ppm/°C) and AEC-Q200 qualified. The seated height is 0.60mm versus 0.50mm for the original part. Verify that your PCB assembly process and clearance requirements accommodate the additional 0.10mm height before implementation.

Q: What does the tolerance specification mean for circuit performance?

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 1.6 kΩ specification. ±0.1% tolerance allows ±1.6 Ohms deviation; ±0.05% allows ±0.8 Ohms deviation; ±0.02% allows ±0.32 Ohms deviation. Tighter tolerances are required in precision analog circuits, measurement instrumentation, and high-accuracy signal conditioning applications.

Q: Are all substitute parts automotive qualified?

A: Susumu RG series and Panasonic ERA-6A series parts carry AEC-Q200 automotive qualification. YAGEO RT0805WRB071K6L does not list AEC-Q200 rating in the provided specifications. Verify automotive qualification requirements for your specific application before selecting YAGEO parts.

Q: What is the significance of temperature coefficient in my application?

A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes per degree Celsius across the operating temperature range. Lower values indicate better stability. At the extremes of the -55°C to 155°C range (210°C span), a ±10ppm/°C part experiences approximately ±0.34% drift, while a ±5ppm/°C part experiences approximately ±0.17% drift. Select based on your circuit's sensitivity to resistance variation over temperature.

Q: Can I mix different manufacturers in the same assembly?

A: Yes. All substitute parts meet identical electrical specifications, package dimensions, and compliance standards. Mixing manufacturers is acceptable from an engineering standpoint. Verify that your procurement and quality assurance processes accommodate multiple qualified suppliers.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. No baking or desiccant storage is required before soldering, simplifying logistics and assembly processes.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting restrictions on hazardous substances in electrical and electronic equipment.
