Engineering Selection Recommendations
Direct Equivalent (Same Specifications): RG2012N-2870-B-T5 provides direct equivalence to the RG2012N-2870-B-T1 with identical electrical specifications (287 Ohms, ±0.1% tolerance, ±10ppm/°C temperature coefficient). The primary difference is active product status and Tape & Reel packaging format. This part is the recommended replacement for obsolete stock.
Upgraded Tolerance Options (Susumu RG Series): RG2012N-2870-W-T1 and RG2012N-2870-W-T5 offer improved ±0.05% tolerance while maintaining the ±10ppm/°C temperature coefficient. These parts are suitable for applications requiring tighter resistance tolerance specifications.
Enhanced Temperature Stability (Susumu RG V-Series): RG2012V-2870-B-T5, RG2012V-2870-W-T1, and RG2012V-2870-W-T5 feature superior ±5ppm/°C temperature coefficient compared to the original ±10ppm/°C specification. RG2012V-2870-P-T1 provides the highest precision at ±0.02% tolerance with ±5ppm/°C temperature coefficient.
Cross-Manufacturer Alternative (Panasonic): ERA-6AEB2870V from Panasonic Electronic Components matches the 287 Ohm resistance, ±0.1% tolerance, and 0.125W power rating. This part carries a higher temperature coefficient of ±25ppm/°C and slightly increased maximum seated height (0.024" vs 0.020"). All parts maintain AEC-Q200 automotive qualification and ROHS3 compliance.
All substitute parts are qualified for identical operating temperature range (-55°C to 155°C) and moisture sensitivity level (MSL 1 - Unlimited).
Frequently Asked Questions (FAQ)
Q: Can RG2012N-2870-B-T5 directly replace RG2012N-2870-B-T1?
A: Yes. Both parts share identical electrical specifications: 287 Ohms, ±0.1% tolerance, 0.125W power rating, ±10ppm/°C temperature coefficient, and 0805 package. The primary difference is packaging format (Tape & Reel vs Bulk) and active product status of the substitute.
Q: What is the difference between RG2012N and RG2012V series?
A: The RG2012V series offers improved temperature coefficient performance at ±5ppm/°C compared to RG2012N at ±10ppm/°C. Both series maintain identical resistance values, power ratings, and package dimensions. RG2012V is suitable for applications requiring enhanced thermal stability.
Q: Are tolerance upgrades (±0.05%, ±0.02%) backward compatible?
A: Yes. Tighter tolerance specifications (±0.05%, ±0.02%) are functionally compatible with designs specified for ±0.1% tolerance. The substitute parts will meet or exceed the original tolerance requirement.
Q: Can ERA-6AEB2870V from Panasonic replace Susumu parts?
A: ERA-6AEB2870V is electrically compatible for 287 Ohm, ±0.1% tolerance applications. The Panasonic part carries a higher temperature coefficient (±25ppm/°C vs ±10ppm/°C) and slightly increased maximum seated height (0.024" vs 0.020"). Both maintain AEC-Q200 qualification and 0805 package compatibility.
Q: What does the packaging designation (T1 vs T5) indicate?
A: T1 and T5 designations indicate different tape reel specifications within Tape & Reel packaging format. Both formats are compatible with standard pick-and-place assembly equipment. Selection depends on specific manufacturing equipment requirements.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance status identical to the original RG2012N-2870-B-T1.
Q: What is the significance of anti-sulfur coating in the RG series?
A: Anti-sulfur coating is specified in Susumu RG series parts. This feature is not explicitly listed for the Panasonic ERA-6AEB2870V. Both part families maintain AEC-Q200 automotive qualification and are suitable for automotive applications.
