Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Active Status):

The RG2012P-2611-B-T5 is the direct active equivalent, maintaining identical tolerance (±0.1% improvement), temperature coefficient (±25ppm/°C), and power rating (0.125W) specifications. This part is available in high inventory (34,523 units) and retains full AEC-Q200 automotive qualification.

For applications requiring improved tolerance performance, the RG2012P-2611-W-T5 provides ±0.05% tolerance while maintaining the same temperature coefficient and power rating. Both parts are ROHS3 compliant and AEC-Q200 qualified.

For applications requiring superior temperature stability, the RG2012V series offers reduced temperature coefficients (±5ppm/°C or ±10ppm/°C) with tolerance options ranging from ±0.02% to ±0.1%. All RG2012V variants maintain 0.125W power rating and AEC-Q200 qualification.

Alternative Manufacturer Substitutes:

The RT0805CRD072K61L (YAGEO) provides electrical equivalence with identical tolerance (±0.25%), temperature coefficient (±25ppm/°C), and power rating (0.125W). This part is active and ROHS3 compliant but does not carry AEC-Q200 automotive qualification.

The 5-2176092-3 (TE Connectivity) offers ±0.1% tolerance and ±25ppm/°C temperature coefficient but features 0.25W (1/4W) power rating, exceeding the original specification. This part is active and ROHS3 compliant but lacks AEC-Q200 qualification.

Selection Criteria:

For automotive and high-reliability applications requiring AEC-Q200 compliance, select from the Susumu RG series substitutes. For general-purpose applications where automotive qualification is not required, YAGEO RT0805CRD072K61L provides direct electrical equivalence. The TE Connectivity part is suitable only when increased power dissipation capability is beneficial to the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-2611-C-T5 be replaced with RG2012P-2611-B-T5?

A: Yes. The RG2012P-2611-B-T5 is a direct substitute. Both parts share identical resistance (2.61 kOhms), package (0805), power rating (0.125W), temperature range (-55°C to 155°C), and AEC-Q200 qualification. The substitute offers improved tolerance (±0.1% versus ±0.25%) and is currently in active production with higher inventory availability.

Q: What is the difference between RG2012P and RG2012V series?

A: The primary difference is temperature coefficient. RG2012P series has ±25ppm/°C temperature coefficient, while RG2012V series has ±5ppm/°C. Both series maintain identical resistance, package, power rating, and AEC-Q200 qualification. RG2012V is selected when superior temperature stability is required.

Q: Can I use the TE Connectivity 5-2176092-3 as a substitute?

A: The 5-2176092-3 is electrically compatible in terms of resistance, tolerance, and temperature coefficient. However, it features 0.25W power rating (double the original 0.125W) and lacks AEC-Q200 automotive qualification. Use this part only in non-automotive applications where the increased power rating does not create thermal or reliability concerns.

Q: Is the YAGEO RT0805CRD072K61L suitable for automotive applications?

A: The RT0805CRD072K61L provides electrical equivalence with identical tolerance (±0.25%), temperature coefficient (±25ppm/°C), and power rating (0.125W). However, it does not carry AEC-Q200 automotive qualification. For automotive applications requiring AEC-Q200 compliance, use Susumu RG series substitutes instead.

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

A: Tolerance specifies the maximum deviation of the actual resistance value from the nominal 2.61 kOhms specification. The original part has ±0.25% tolerance, meaning actual values range from 2.5948 kOhms to 2.6252 kOhms. Tighter tolerance substitutes (±0.1%, ±0.05%, ±0.02%) provide resistance values closer to the nominal specification, improving circuit accuracy in precision applications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. The original RG2012P-2611-C-T5 is also ROHS3 compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, all listed substitutes are mechanically and electrically compatible within the same 0805 package footprint. However, for consistency in circuit performance, particularly in precision analog circuits, use the same part number across all instances of the 2.61 kOhms resistor value.

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

A: Temperature coefficient indicates how much the resistance value changes with temperature. The original part has ±25ppm/°C, meaning resistance changes approximately 0.0025% per degree Celsius. Lower temperature coefficients (±5ppm/°C or ±10ppm/°C) indicate better stability across the -55°C to 155°C operating range, beneficial for precision measurement and signal conditioning circuits.
