Engineering Selection Recommendations

Direct Equivalent (Same Specifications): RG2012N-362-B-T5 is the primary direct equivalent from Susumu. This part maintains identical electrical specifications (3.6 kOhms ±0.1%, ±10ppm/°C) and is in active production status. The only difference is packaging format (Tape & Reel versus the original format), which does not affect electrical performance. This part is recommended for direct replacement in existing designs.

ERA-6ARB362V from Panasonic Electronic Components is an alternative direct equivalent with identical tolerance and temperature coefficient specifications. This part is AEC-Q200 rated and in active production with higher inventory availability (5548 units).

Upgraded Specifications (Improved Tolerance): Parts with ±0.05% tolerance (RG2012N-362-W-T1, RG2012N-362-W-T5, ERA-6ARW362V, RT0805WRB073K6L) provide tighter tolerance performance while maintaining all other electrical parameters. These parts are suitable for applications requiring improved accuracy.

Parts with ±0.02% tolerance (RG2012V-362-P-T1) provide the highest tolerance specification available in this series.

Upgraded Specifications (Improved Temperature Coefficient): Susumu RG2012V series parts feature ±5ppm/°C temperature coefficient compared to ±10ppm/°C in the original part. These upgrades reduce temperature-dependent resistance drift and are suitable for precision applications.

Compliance and Certification: All substitute parts listed maintain ROHS3 compliance, AEC-Q200 automotive qualification (where specified), and MSL 1 moisture sensitivity rating. All parts are suitable for automotive and industrial applications requiring equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-362-B-T5 be used as a direct replacement for RG2012N-362-B-T1?

A: Yes. RG2012N-362-B-T5 is a direct electrical equivalent with identical resistance (3.6 kOhms), tolerance (±0.1%), power rating (0.125W), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The primary difference is packaging format (Tape & Reel). Both parts are 0805 package with identical footprint and mounting requirements.

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

A: The RG2012V series features an improved temperature coefficient of ±5ppm/°C compared to ±10ppm/°C in the RG2012N series. Both series maintain identical resistance values, power ratings, and package specifications. The RG2012V series is suitable for applications requiring reduced temperature-dependent drift.

Q: Are Panasonic ERA-6ARB362V and ERA-6ARW362V compatible with the original RG2012N-362-B-T1?

A: ERA-6ARB362V is electrically compatible with identical specifications. ERA-6ARW362V has improved tolerance (±0.05% versus ±0.1%) and is also compatible. Both parts are 0805 package with identical footprint. The maximum seated height is 0.60mm compared to 0.50mm for the original part; this difference is within standard PCB design tolerances for 0805 components.

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

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 3.6 kOhms specification. ±0.1% tolerance allows deviation of ±3.6 ohms. ±0.05% tolerance allows deviation of ±1.8 ohms. ±0.02% tolerance allows deviation of ±0.72 ohms. Tighter tolerance parts are suitable for precision analog circuits, measurement equipment, and applications with strict accuracy requirements.

Q: Are all listed substitute parts AEC-Q200 rated?

A: Susumu RG series parts and Panasonic ERA-6A series parts are explicitly AEC-Q200 rated. YAGEO RT0805WRB073K6L does not list AEC-Q200 rating in the provided specifications. For automotive applications requiring AEC-Q200 compliance, use Susumu or Panasonic parts.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient (ppm/°C) specifies how the resistance value changes with temperature. ±10ppm/°C means the resistance changes by 10 parts per million per degree Celsius. ±5ppm/°C represents improved stability. For applications operating across wide temperature ranges (-55°C ~ 155°C), lower temperature coefficient values reduce resistance drift and improve circuit stability.

Q: Can parts with different tolerance specifications be mixed in the same circuit?

A: Yes, parts with different tolerance specifications can be used in the same circuit. However, circuit design should account for the tolerance of the least precise component. For critical applications, use consistent tolerance specifications across all resistors in a given circuit stage.

Q: What is MSL 1 moisture sensitivity level?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning the component has no moisture absorption limitations and does not require special moisture control during storage or handling. This simplifies inventory management and manufacturing processes.
