Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications, Active Status):

RG2012P-2871-B-T5 is the direct equivalent of RG2012P-2871-B-T1. Both parts share identical electrical specifications: 2.87 kOhms ±0.1% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient, and 0805 package. The primary difference is product status; RG2012P-2871-B-T5 is active with 1088 units in stock, whereas the original part is obsolete. This substitution requires no circuit redesign and maintains all performance characteristics.

Upgraded Alternatives (Improved Temperature Coefficient):

RG2012N-2871-B-T5 and RG2012V-2871-B-T5 offer improved temperature stability with ±10ppm/°C and ±5ppm/°C coefficients respectively, compared to the original ±25ppm/°C. Both maintain ±0.1% tolerance and 0.125W rating in 0805 package with AEC-Q200 qualification. These upgrades are suitable for applications requiring enhanced thermal stability without tolerance changes.

Upgraded Alternatives (Improved Tolerance):

RG2012N-2871-W-T1, RG2012P-2871-W-T5, RG2012V-2871-W-T1, and RG2012V-2871-W-T5 provide ±0.05% tolerance, representing a 2× improvement over the original ±0.1%. RG2012V-2871-P-T1 offers the highest precision at ±0.02% tolerance with ±5ppm/°C temperature coefficient. These upgrades are applicable to precision analog circuits and measurement applications.

Cross-Manufacturer Alternative:

ERA-6AEB2871V (Panasonic) provides electrical equivalence with identical 2.87 kOhms ±0.1% specifications, 0.125W rating, and AEC-Q200 qualification. This option is suitable when Susumu parts are unavailable, with 22804 units in stock. The TE Connectivity part 5-2176092-6 is not recommended as a direct substitute due to higher power rating (0.25W) and absence of AEC-Q200 rating.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2871-B-T5 replace RG2012P-2871-B-T1 without circuit modification?

A: Yes. RG2012P-2871-B-T5 is a direct electrical equivalent with identical resistance, tolerance, power rating, and temperature coefficient. The only difference is packaging format (Tape & Reel vs. bulk) and active product status. No circuit redesign is required.

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

A: The RG2012N series features ±10ppm/°C temperature coefficient, while RG2012V series features ±5ppm/°C. Both are available in multiple tolerance grades (±0.1%, ±0.05%, ±0.02%). Selection depends on thermal stability requirements of the application.

Q: Is RG2012V-2871-P-T1 suitable for all applications requiring RG2012P-2871-B-T1?

A: RG2012V-2871-P-T1 is suitable for applications where improved tolerance (±0.02% vs. ±0.1%) and temperature coefficient (±5ppm/°C vs. ±25ppm/°C) provide circuit benefits. For applications with no precision requirements, the direct equivalent RG2012P-2871-B-T5 is more cost-effective.

Q: Why is 5-2176092-6 not recommended as a substitute?

A: While 5-2176092-6 matches the 2.87 kOhms resistance and ±0.1% tolerance, it differs in two critical aspects: power rating is 0.25W (double the original 0.125W) and it lacks AEC-Q200 automotive qualification. For automotive applications, AEC-Q200 rated parts are required.

Q: Can ERA-6AEB2871V be used in automotive applications?

A: Yes. ERA-6AEB2871V carries AEC-Q200 qualification and matches all electrical specifications of the original part. It is suitable for automotive applications and offers significantly higher inventory availability (22804 units).

Q: What packaging format should be selected for production assembly?

A: RG2012P-2871-B-T5, RG2012N-2871-B-T5, and all RG2012V variants are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. Bulk packaging is not available for these active alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and handling requirements of the original part.
