Engineering Selection Recommendations

For Direct Replacement (Equivalent Electrical and Mechanical Performance):

Select RG2012P-2943-B-T5 (Susumu) or ERA-6AEB2943V (Panasonic) when an active-status equivalent is required. Both parts maintain the 0.125W power rating, 0805 package, and automotive AEC-Q200 qualification. RG2012P-2943-B-T5 offers improved ±0.1% tolerance over the original ±0.25%. ERA-6AEB2943V provides equivalent specifications with higher inventory availability (14,461 units in stock).

For Improved Tolerance Specifications:

Select RG2012N-2943-W-T1 (Susumu) for the tightest tolerance specification (±0.05%) combined with superior temperature coefficient (±10ppm/°C). This part is active and maintains full automotive AEC-Q200 compliance. Alternatively, RG2012P-2943-W-T5 (Susumu) offers ±0.05% tolerance with ±25ppm/°C temperature coefficient.

For Higher Power Dissipation Requirements:

Select 3-2176094-8 (TE Connectivity) when 0.25W (1/4W) power rating is required. This part maintains 294 kOhms resistance, ±0.1% tolerance, and 0805 package form factor. Height-seated maximum is 0.026" (0.65mm) compared to 0.020" (0.50mm) for the original part.

For Alternative Manufacturer Sources:

Select RT0805BRD07294KL (YAGEO) as an active-status alternative from a different manufacturer. This part matches the original specifications exactly (294 kΩ, ±0.1%, 0.125W, 0805 package, ±25ppm/°C). Note: AEC-Q200 qualification is not listed for YAGEO parts.

For Enhanced Feature Set:

Select PTN0805E2943BST1 (Vishay Dale) when anti-sulfur, moisture-resistant, and non-inductive characteristics are required. This part offers 0.2W (1/5W) power rating with ±0.1% tolerance and 0805 package, though height-seated maximum is 0.033" (0.84mm).

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2943-C-T5 be replaced with a part having tighter tolerance?

A: Yes. Parts with ±0.1% or ±0.05% tolerance are direct electrical substitutes. Tighter tolerance specifications are backward-compatible with applications designed for ±0.25% tolerance. RG2012N-2943-W-T1 (±0.05%) and RG2012P-2943-B-T5 (±0.1%) are suitable replacements.

Q: Are YAGEO RT0805 series parts compatible with Susumu RG2012 series?

A: Yes, from an electrical and mechanical standpoint. Both manufacturers provide 294 kΩ, ±0.1% or ±0.25%, 0.125W, 0805 package resistors with identical physical dimensions and operating temperature ranges. However, YAGEO parts do not carry AEC-Q200 automotive qualification. Verify automotive compliance requirements before substitution.

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

A: Both are Susumu thin film 0805 resistors with identical mechanical specifications. The primary differences are temperature coefficient (RG2012P: ±25ppm/°C; RG2012N: ±10ppm/°C) and tolerance options. RG2012N series offers superior temperature stability.

Q: Can I use 3-2176094-8 (0.25W) in place of RG2012P-2943-C-T5 (0.125W)?

A: Yes, from an electrical standpoint. The 0.25W part has higher power dissipation capability and is mechanically compatible (0805 package). However, the seated height is 0.026" (0.65mm) versus 0.020" (0.50mm) for the original part. Verify PCB layout clearance before substitution.

Q: Is Panasonic ERA-6AEB2943V a suitable replacement for automotive applications?

A: Yes. ERA-6AEB2943V carries AEC-Q200 automotive qualification, matches the original 294 kΩ resistance, 0.125W power rating, and 0805 package. It offers improved ±0.1% tolerance and has significantly higher inventory availability (14,461 units).

Q: What are the key parameters that must match for substitution?

A: Resistance value (294 kΩ exact), package (0805 mandatory), power rating (0.125W minimum), and operating temperature range (-55°C to 155°C minimum). Tolerance and temperature coefficient can be equal or better. RoHS3 compliance and MSL 1 rating must be maintained.

Q: Can I substitute with a part having a different temperature coefficient?

A: Yes, if the application permits. Lower temperature coefficients (±10ppm/°C or ±15ppm/°C) provide better stability across temperature extremes. Higher coefficients are not acceptable. Verify circuit performance requirements before selecting parts with different temperature coefficients.

Q: Are all listed substitutes in active production status?

A: No. The original RG2012P-2943-C-T5 is obsolete. All recommended substitutes are active-status parts. Panasonic ERA-6AEB2943V and Susumu RG2012 series variants have the highest inventory availability.
