Engineering Selection Recommendations

Direct Replacement (Same Electrical Performance): The RG2012N-1471-B-T5 and RG2012N-1471-W-T5 are direct active replacements from Susumu's RG series. Both maintain the same power rating (0.125W), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification as the obsolete RG2012N-1471-C-T5. The RG2012N-1471-B-T5 offers improved tolerance (±0.1% versus ±0.25%), while RG2012N-1471-W-T5 provides tighter tolerance (±0.05%). Both are available in Tape & Reel packaging suitable for production environments.

Enhanced Performance Alternatives (Susumu RG Series): The RG2012V series variants (RG2012V-1471-B-T5, RG2012V-1471-P-T1, RG2012V-1471-W-T1, RG2012V-1471-W-T5) provide superior temperature coefficient performance (±5ppm/°C versus ±10ppm/°C), resulting in improved stability across the operating temperature range. These parts maintain identical resistance, power rating, package, and AEC-Q200 qualification. Selection among these variants depends on tolerance requirements: ±0.1% (B-T5), ±0.02% (P-T1), or ±0.05% (W-T1, W-T5).

Cross-Manufacturer Alternative: The Vishay Dale TNPW08051K47BYEA provides higher power dissipation capability (0.26W versus 0.125W) and extended upper operating temperature (175°C versus 155°C). This part is suitable for applications requiring thermal margin or higher power handling. The ±0.1% tolerance and ±10ppm/°C temperature coefficient are equivalent to the original specification. AEC-Q200 automotive qualification and anti-sulfur coating are maintained.

All substitute parts are ROHS3 compliant, MSL 1 rated, and maintain the 0805 (2012 Metric) package footprint for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-1471-B-T5 be used as a direct replacement for RG2012N-1471-C-T5?

A: Yes. The RG2012N-1471-B-T5 is a direct replacement. Both parts share identical resistance (1.47 kOhms), power rating (0.125W), package (0805), operating temperature range (-55°C to 155°C), and AEC-Q200 qualification. The RG2012N-1471-B-T5 offers tighter tolerance (±0.1% versus ±0.25%), which is a performance improvement with no compatibility issues.

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

A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C temperature coefficient, while RG2012V series has ±5ppm/°C. The RG2012V series provides superior temperature stability. All other electrical and mechanical parameters remain identical. Selection depends on circuit requirements for temperature stability.

Q: Can the Vishay Dale TNPW08051K47BYEA replace the Susumu RG2012N-1471-C-T5?

A: Yes, with considerations. The TNPW08051K47BYEA maintains the same resistance, tolerance (±0.1%), package (0805), and AEC-Q200 qualification. It provides higher power rating (0.26W versus 0.125W) and extended operating temperature (175°C versus 155°C). The ±10ppm/°C temperature coefficient is equivalent. This part is suitable for applications requiring additional thermal margin or higher power dissipation.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly and production environments.

Q: Do tolerance differences affect PCB layout or footprint?

A: No. Tolerance differences (±0.25%, ±0.1%, ±0.05%, ±0.02%) do not affect physical footprint or PCB layout. All parts use the identical 0805 (2012 Metric) package with dimensions 2.00mm L × 1.25mm W and maximum seated height of 0.50mm (0.020").

Q: What is the significance of the tolerance grade for circuit design?

A: Tolerance grade determines the maximum deviation from the nominal 1.47 kOhms resistance value. Tighter tolerance (lower percentage) provides more precise resistance values. For general-purpose applications, ±0.25% or ±0.1% is typically sufficient. Precision analog circuits, reference networks, or measurement applications may require ±0.05% or ±0.02% tolerance grades.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.
