Frequently Asked Questions (FAQ)

Q: Can I substitute the RG2012P-4640-C-T5 with any of the listed alternatives?

A: Substitution depends on application requirements. All Susumu RG series parts maintain AEC-Q200 automotive qualification and are electrically compatible. TE Connectivity and YAGEO alternatives are electrically compatible but lack AEC-Q200 certification. For automotive applications, use only Susumu RG series substitutes.

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

A: The series designation indicates temperature coefficient performance. RG2012P series has ±25ppm/°C, RG2012N series has ±10ppm/°C, and RG2012V series has ±5ppm/°C. All maintain identical 0805 package dimensions and AEC-Q200 qualification. Select based on temperature stability requirements.

Q: Are the tolerance grades (B, W, P) interchangeable?

A: Tolerance grades are not interchangeable. B indicates ±0.1% tolerance, W indicates ±0.05% tolerance, and P indicates ±0.02% tolerance. The original part uses C designation (±0.25%). Substitutes with tighter tolerances (B, W, P) are acceptable upgrades. Substitutes with looser tolerances are not acceptable.

Q: Does the 0805 package dimension remain identical across all substitutes?

A: Yes. All listed substitutes use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). PCB layout compatibility is maintained across all substitutes.

Q: Why does the TE Connectivity part (8-2176091-6) have a higher power rating (0.25W)?

A: The TE Connectivity part is rated for 0.25W (1/4W) compared to the original 0.125W (1/8W). Higher power rating provides additional thermal margin and does not affect electrical compatibility. This part is suitable for applications where thermal headroom is beneficial, though it is not required for direct substitution.

Q: What is the significance of the T5 and T1 packaging designations?

A: T5 and T1 indicate different tape and reel packaging configurations for automated assembly. Both are Tape & Reel (TR) packaging suitable for pick-and-place equipment. Selection between T5 and T1 depends on assembly equipment compatibility, not electrical performance.

Q: Is the RG2012P-4640-C-T5 still available for purchase?

A: The RG2012P-4640-C-T5 is classified as obsolete. However, 922 units are currently in stock. For new designs or long-term supply assurance, select from the active Susumu RG series substitutes, which offer improved specifications and guaranteed availability.

Q: Can I use the YAGEO RT0805CRD07464RL as a direct replacement in automotive applications?

A: The YAGEO RT0805CRD07464RL is electrically equivalent to the original part with identical ±0.25% tolerance and ±25ppm/°C temperature coefficient. However, it does not carry AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive qualification is not required.

Q: What is the advantage of selecting RG2012V-4640-P-T1 over other substitutes?

A: The RG2012V-4640-P-T1 offers the tightest tolerance (±0.02%) and lowest temperature coefficient (±5ppm/°C) among all available substitutes. This combination provides superior accuracy and temperature stability, making it suitable for precision measurement circuits, calibration applications, and high-performance analog circuits where component tolerance and drift are critical parameters.
