Engineering Selection Recommendations

Direct Substitution (Susumu RG Series):

All Susumu RG2012N and RG2012V variants listed provide direct substitution for the RG2012N-2800-C-T5. These parts maintain identical 280 Ohm resistance, 0805 package, AEC-Q200 automotive qualification, anti-sulfur coating, and RoHS3 compliance. All Susumu alternatives are currently in active product status, ensuring long-term availability and supply chain stability.

Tolerance Upgrade Path:

The RG2012N-2800-B-T5 provides ±0.1% tolerance (improved from ±0.25%) while maintaining identical temperature coefficient and power rating. The RG2012N-2800-W-T1 and RG2012N-2800-W-T5 offer ±0.05% tolerance for applications requiring tighter resistance control.

Temperature Coefficient Enhancement:

The RG2012V series (RG2012V-2800-B-T5, RG2012V-2800-P-T1, RG2012V-2800-W-T1, RG2012V-2800-W-T5) provides ±5ppm/°C temperature coefficient compared to ±10ppm/°C in the original part, delivering improved stability across the operating temperature range. The RG2012V-2800-P-T1 combines the lowest tolerance (±0.02%) with the lowest temperature coefficient (±5ppm/°C).

Alternative Manufacturer Option:

The Vishay Dale TNPW0805280RBYEA provides cross-manufacturer substitution with ±0.1% tolerance and extended operating temperature range to 175°C. This part features higher power rating (0.26W versus 0.125W), providing additional thermal margin. The TNPW0805280RBYEA maintains AEC-Q200 qualification, anti-sulfur coating, and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-2800-C-T5 be replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain the critical electrical and mechanical parameters: 280 Ohm resistance, 0805 package, 0.125W minimum power rating, AEC-Q200 automotive qualification, anti-sulfur coating, and RoHS3 compliance. Direct substitution is supported across all variants.

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

A: The RG2012V series provides improved temperature coefficient performance (±5ppm/°C versus ±10ppm/°C). Both series maintain identical resistance, package, and compliance specifications. Selection between series depends on application requirements for temperature stability.

Q: Are tighter tolerance parts (±0.05%, ±0.02%) compatible with circuits designed for ±0.25% tolerance?

A: Yes. Lower tolerance values represent improved accuracy and are fully compatible with applications designed for higher tolerance specifications. Tighter tolerance parts provide enhanced performance without circuit modification.

Q: What is the significance of the T1 and T5 designations in part numbers?

A: The T1 and T5 designations indicate different packaging configurations (Tape & Reel specifications). Both are compatible for the same electrical and mechanical applications. Selection depends on procurement and assembly process requirements.

Q: Can the Vishay Dale TNPW0805280RBYEA be used as a direct replacement?

A: Yes. The TNPW0805280RBYEA provides direct substitution with identical 280 Ohm resistance, 0805 package, and AEC-Q200 qualification. The higher power rating (0.26W versus 0.125W) and extended temperature range (to 175°C) provide additional performance margin without affecting circuit compatibility.

Q: Does the higher power rating of the TNPW0805280RBYEA affect circuit performance?

A: No. Power rating indicates the maximum power the component can safely dissipate. A higher power rating does not affect electrical performance in circuits operating below the original part's power specification. The TNPW0805280RBYEA operates identically to the RG2012N-2800-C-T5 in all standard applications.

Q: Are all substitute parts RoHS3 compliant and AEC-Q200 qualified?

A: Yes. All substitute parts listed maintain RoHS3 compliance and AEC-Q200 automotive qualification, ensuring regulatory compliance and reliability standards equivalent to the original part.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1 rating, requiring no special storage or handling procedures.
