Engineering Selection Recommendations

Primary Recommendation: Susumu RG Series Upgrades

The Susumu RG2012 series upgrades (RG2012N and RG2012V variants) are the preferred substitutes for the obsolete RG2012P-8661-C-T5. These parts maintain identical mechanical compatibility, electrical resistance, power rating, and operating temperature range while offering improved tolerance specifications and temperature coefficient performance. All Susumu alternatives retain AEC-Q200 automotive qualification and ROHS3 compliance.

Tolerance-Based Selection:

For applications requiring tolerance improvement beyond ±0.25%, select from the following active Susumu alternatives:

RG2012P-8661-B-T5 or RG2012N-8661-B-T5: ±0.1% tolerance
RG2012P-8661-W-T5 or RG2012N-8661-W-T1: ±0.05% tolerance
RG2012V-8661-W-T1 or RG2012V-8661-W-T5: ±0.05% tolerance with ±5ppm/°C temperature coefficient
RG2012V-8661-P-T1: ±0.02% tolerance with ±5ppm/°C temperature coefficient

Temperature Coefficient Consideration:

Applications sensitive to temperature-induced resistance drift benefit from RG2012V series variants, which feature ±5ppm/°C temperature coefficient compared to ±25ppm/°C in the original part. The RG2012N series offers intermediate performance at ±10ppm/°C.

Cross-Manufacturer Alternatives:

YAGEO RT0805CRD078K66L provides direct electrical and mechanical equivalence with identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C). This part is active and ROHS3 compliant, suitable for applications where manufacturer diversification is required.

TE Connectivity 9-2176092-8 offers higher power rating (0.25W vs. 0.125W) with equivalent tolerance and temperature coefficient. This part does not carry AEC-Q200 qualification and is suitable only for non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-8661-W-T5 replace RG2012P-8661-C-T5 in automotive applications?

A: Yes. RG2012V-8661-W-T5 maintains identical resistance (8.66 kOhms), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). It improves tolerance from ±0.25% to ±0.05% and reduces temperature coefficient from ±25ppm/°C to ±5ppm/°C. Both parts are AEC-Q200 qualified and ROHS3 compliant.

Q: What is the difference between RG2012P, RG2012N, and RG2012V series?

A: The letter designation indicates temperature coefficient performance. RG2012P series features ±25ppm/°C, RG2012N series features ±10ppm/°C, and RG2012V series features ±5ppm/°C. All three series are available in multiple tolerance grades (±0.25%, ±0.1%, ±0.05%, ±0.02%) and maintain identical mechanical compatibility and AEC-Q200 qualification.

Q: Is RT0805CRD078K66L suitable for automotive applications?

A: RT0805CRD078K66L is not AEC-Q200 qualified. While it provides electrical and mechanical equivalence with identical tolerance and temperature coefficient, it is not recommended for automotive applications requiring AEC-Q200 certification. Use Susumu RG series alternatives for automotive compliance.

Q: Can TE Connectivity 9-2176092-8 be used as a direct replacement?

A: TE Connectivity 9-2176092-8 is mechanically and electrically compatible but differs in power rating (0.25W vs. 0.125W) and lacks AEC-Q200 qualification. It is suitable for non-automotive applications where higher power dissipation capacity is beneficial. For automotive applications, use Susumu RG series alternatives.

Q: What packaging format is available for substitute parts?

A: All substitute parts listed are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The original RG2012P-8661-C-T5 packaging format is not specified in available data; verify packaging requirements against design specifications before component selection.

Q: Are all substitute parts ROHS3 compliant?

A: All Susumu RG series substitutes and YAGEO RT0805CRD078K66L are ROHS3 compliant. TE Connectivity 9-2176092-8 is ROHS3 compliant with REACH status listed as Vendor Undefined. Verify compliance documentation with supplier for specific application requirements.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: All listed substitute parts maintain MSL 1 (Unlimited), identical to the original RG2012P-8661-C-T5. This classification indicates no moisture sensitivity restrictions for storage or handling.
