Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Continuity):

The RT0805CRD073K16L from YAGEO provides electrical and mechanical equivalence to the RG2012P-3161-C-T5 with identical resistance (3.16 kOhms), tolerance (±0.25%), power rating (0.125W), and temperature coefficient (±25ppm/°C). This part is active in production and maintains ROHS3 compliance and MSL 1 rating. Selection of this part requires no circuit redesign and maintains the original performance envelope.

For Precision Upgrade (Automotive AEC-Q200 Continuation):

The Susumu RG2012V series parts (RG2012V-3161-B-T5, RG2012V-3161-W-T1, RG2012V-3161-W-T5, RG2012V-3161-P-T1) are active production alternatives that maintain AEC-Q200 automotive qualification while offering superior temperature coefficient performance (±5ppm/°C versus ±25ppm/°C). These parts are suitable for applications requiring enhanced thermal stability and are available in multiple tolerance grades (±0.1%, ±0.05%, ±0.02%).

For General Precision Applications:

The Susumu RG2012N series (RG2012N-3161-B-T5, RG2012N-3161-W-T1) and RG2012P series (RG2012P-3161-B-T5, RG2012P-3161-W-T5) provide active alternatives with tighter tolerances (±0.1% to ±0.05%) while maintaining AEC-Q200 qualification and the same 0805 package footprint.

For Higher Power Dissipation Requirements:

The TE Connectivity 6-2176092-0 offers doubled power rating (0.25W versus 0.125W) in the same 0805 package with matching resistance and tolerance specifications. This part is suitable for applications requiring increased thermal headroom, though it does not carry AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-3161-C-T5 be replaced with a part having tighter tolerance?

A: Yes. Parts with tolerance specifications tighter than ±0.25% (such as ±0.1%, ±0.05%, or ±0.02%) are direct functional upgrades. The circuit will operate within the original design specifications since tighter tolerance represents improved accuracy. Examples include RG2012N-3161-B-T5 (±0.1%), RG2012P-3161-W-T5 (±0.05%), and RG2012V-3161-P-T1 (±0.02%).

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

A: All three series maintain the same 3.16 kOhms resistance, 0805 package, and 0.125W power rating. The primary differences are temperature coefficient performance and tolerance options. The RG2012N series has ±10ppm/°C temperature coefficient, the RG2012P series has ±25ppm/°C, and the RG2012V series has ±5ppm/°C. Selection depends on thermal stability requirements for the application.

Q: Is the TE Connectivity 6-2176092-0 a suitable replacement?

A: The TE Connectivity 6-2176092-0 is electrically equivalent with matching resistance (3.16 kOhms), tolerance (±0.1%), and temperature coefficient (±25ppm/°C). However, it has doubled power rating (0.25W versus 0.125W) and does not carry AEC-Q200 automotive qualification. It is suitable for non-automotive applications or where increased power dissipation capacity is beneficial. The 0805 package footprint is identical.

Q: Can the YAGEO RT0805CRD073K16L be used as a direct substitute?

A: Yes. The YAGEO RT0805CRD073K16L provides direct electrical and mechanical equivalence with identical resistance (3.16 kOhms), tolerance (±0.25%), power rating (0.125W), temperature coefficient (±25ppm/°C), and 0805 package. This part is active in production and maintains ROHS3 compliance. No circuit modifications are required.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Parts carrying this rating have undergone specific reliability and performance testing for automotive applications. The Susumu RG2012 series maintains this qualification across all variants. The YAGEO and TE Connectivity alternatives do not carry AEC-Q200 qualification and should be evaluated for suitability in automotive applications.

Q: Are all substitute parts available in the same 0805 package?

A: Yes. All substitute parts listed are manufactured in the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical board layout compatibility is maintained across all alternatives.

Q: What is the difference between Tape & Reel (TR) and other packaging options?

A: The RG2012P-3161-C-T5 original part does not specify packaging format. All active substitute parts are available in Tape & Reel (TR) packaging, which is standard for automated assembly processes. Tape & Reel packaging is compatible with standard pick-and-place equipment used in modern electronics manufacturing.

Q: Can a part with higher temperature coefficient be used instead of the original?

A: No. The temperature coefficient specification defines how much the resistance value changes with temperature. A higher temperature coefficient (larger ppm/°C value) represents worse thermal stability. Only parts with equal or lower temperature coefficient values should be selected as substitutes.
