Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-202-W-T5 is the direct equivalent to RG2012P-202-W-T1. Both parts share identical electrical specifications: 2 kOhms ±0.05% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is recommended for direct replacement in new designs and production.

Superior Performance Alternatives (Tighter Tolerance and Temperature Coefficient):

RG2012N-202-W-T5, RG2012V-202-W-T1, and RG2012V-202-W-T5 offer improved temperature stability with ±10ppm/°C or ±5ppm/°C temperature coefficients compared to the original ±25ppm/°C specification. RG2012V-202-P-T1 provides the highest precision at ±0.02% tolerance with ±5ppm/°C temperature coefficient. These parts are suitable for applications requiring enhanced thermal stability and tighter resistance accuracy.

Cross-Manufacturer Alternatives:

ERA-6ARW202V (Panasonic Electronic Components) and RT0805WRB072KL (YAGEO) provide functionally equivalent performance with ±0.05% tolerance and ±10ppm/°C temperature coefficient. Both maintain AEC-Q200 automotive qualification and 0805 package compatibility. These alternatives ensure supply chain flexibility and availability.

Lower Precision Alternative:

RG2012P-202-B-T5 features ±0.1% tolerance with ±25ppm/°C temperature coefficient. This part is suitable only for applications where the original ±0.05% tolerance specification is not required. Extensive inventory availability (229,993 pcs) makes this option viable for cost-sensitive applications with relaxed tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-202-W-T5 be used as a direct replacement for RG2012P-202-W-T1?

A: Yes. RG2012P-202-W-T5 is a direct functional equivalent with identical electrical specifications: 2 kOhms ±0.05%, 0.125W, ±25ppm/°C temperature coefficient, and AEC-Q200 qualification. The difference is packaging format and active product status. Both are suitable for the same circuit applications.

Q: What is the difference between RG2012N-202-W-T5 and RG2012P-202-W-T5?

A: Both parts share 2 kOhms ±0.05% resistance and 0.125W power rating. The key difference is temperature coefficient: RG2012N-202-W-T5 provides ±10ppm/°C stability compared to ±25ppm/°C for RG2012P-202-W-T5. RG2012N-202-W-T5 is suitable for applications requiring improved thermal performance.

Q: Are RG2012V series parts compatible with the original RG2012P-202-W-T1?

A: Yes. RG2012V-202-W-T1 and RG2012V-202-W-T5 maintain the same 2 kOhms ±0.05% specification and 0.125W power rating. Both feature superior ±5ppm/°C temperature coefficient compared to the original ±25ppm/°C. These parts are pin-compatible and functionally superior for thermal stability.

Q: Can I use ERA-6ARW202V or RT0805WRB072KL from different manufacturers?

A: Yes. Both ERA-6ARW202V (Panasonic) and RT0805WRB072KL (YAGEO) meet the mandatory specifications: 2 kOhms ±0.05%, 0.125W, 0805 package, AEC-Q200 qualification, and -55°C to 155°C operating range. These cross-manufacturer alternatives provide supply chain options while maintaining electrical compatibility.

Q: Is RG2012P-202-B-T5 with ±0.1% tolerance acceptable?

A: RG2012P-202-B-T5 is acceptable only for applications where ±0.1% tolerance meets circuit requirements. The original RG2012P-202-W-T1 specifies ±0.05% tolerance. Use RG2012P-202-B-T5 only when design specifications explicitly allow the wider ±0.1% tolerance range.

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

A: The T1 and T5 suffixes indicate different packaging formats. T1 represents bulk packaging, while T5 represents Tape & Reel (TR) packaging. Both formats contain identical components with the same electrical specifications. Selection depends on assembly process requirements and inventory management practices.

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

A: All substitute parts listed are RoHS3 compliant. AEC-Q200 automotive qualification is confirmed for Susumu RG series, Panasonic ERA-6ARW202V, and applicable to automotive applications. RT0805WRB072KL from YAGEO does not list AEC-Q200 rating in provided specifications; verify automotive qualification requirements with manufacturer if needed for automotive applications.

Q: What is the maximum height difference between substitute parts?

A: The original RG2012P-202-W-T1 has a maximum seated height of 0.020" (0.50mm). ERA-6ARW202V and RT0805WRB072KL have maximum seated heights of 0.024" (0.60mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances for 0805 package components and does not affect circuit functionality.
