Engineering Selection Recommendations
Direct Equivalent (Same Tolerance & Temperature Coefficient):
RG2012N-202-B-T5 is the direct equivalent to RG2012N-202-B-T1. Both components share identical electrical specifications (2 kOhms ±0.1%, ±10ppm/°C) and are manufactured by Susumu with AEC-Q200 automotive qualification. The primary difference is packaging format: RG2012N-202-B-T5 is supplied in Tape & Reel format versus bulk packaging. This part is active and suitable for direct substitution in production environments.
ERA-6ARB202V (Panasonic Electronic Components) provides an alternative direct equivalent with matching tolerance (±0.1%) and temperature coefficient (±10ppm/°C). This part maintains AEC-Q200 qualification and is actively produced with higher inventory availability (8509 Pcs).
Upgraded Specifications (Improved Tolerance):
RG2012N-202-W-T1 and RG2012N-202-W-T5 offer improved tolerance of ±0.05% while maintaining the ±10ppm/°C temperature coefficient. These Susumu parts are suitable for applications requiring tighter resistance tolerances and are actively produced.
ERA-6ARW202V (Panasonic Electronic Components) provides ±0.05% tolerance with ±10ppm/°C temperature coefficient and active production status.

Frequently Asked Questions (FAQ)
Q: Can RG2012N-202-B-T5 be used as a direct replacement for RG2012N-202-B-T1?
A: Yes. Both parts share identical electrical specifications (2 kOhms ±0.1%, ±10ppm/°C temperature coefficient, 0.125W, 0805 package). The difference is packaging format: RG2012N-202-B-T5 is supplied in Tape & Reel format while RG2012N-202-B-T1 was supplied in bulk. RG2012N-202-B-T5 is actively produced and suitable for direct substitution.
Q: What is the difference between RG2012N and RG2012V series?
A: The RG2012V series features an improved temperature coefficient of ±5ppm/°C compared to the RG2012N series at ±10ppm/°C. Both series maintain the same resistance value, power rating, and package type. RG2012V components are suitable for applications requiring superior temperature stability.
Q: Can I use a ±0.05% tolerance part in place of a ±0.1% tolerance part?
A: Yes. A tighter tolerance specification (±0.05%) is compatible with applications designed for ±0.1% tolerance. The component will meet or exceed the original specification requirements. Examples include RG2012N-202-W-T1, ERA-6ARW202V, and RT0805WRB072KL.
Q: Are all substitute parts AEC-Q200 qualified?
A: All Susumu (RG series) and Panasonic (ERA-6A series) substitute parts listed are AEC-Q200 qualified. The YAGEO RT0805WRB072KL does not carry AEC-Q200 qualification. Verify automotive qualification requirements for your specific application.
Q: What is the height difference between manufacturers?
A: Susumu RG2012 series components have a maximum seated height of 0.020" (0.50mm). Panasonic ERA-6A and YAGEO RT series components have a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference may impact PCB layout in space-constrained applications.
Q: Can I mix different manufacturers in the same design?
A: Yes, provided all parts meet the mandatory electrical specifications (2 kOhms, 0.125W, 0805 package, -55°C to 155°C operating range) and application-specific requirements such as AEC-Q200 qualification. Verify component availability and supply chain consistency for production planning.
Q: What does MSL 1 (Unlimited) mean?
A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to soldering.
