Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-2943-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 294 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter (lower) than ±0.25%
• Power rating: Can be equal to or higher than 0.125W
• Operating temperature range: Can be equal to or wider than -55°C ~ 155°C
• Anti-sulfur feature: Present in all qualified substitutes

All substitute parts listed maintain identical resistance, package, composition, and automotive qualification while offering improved tolerance specifications or enhanced power handling capabilities.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-2943-B-T5, RG2012N-2943-W-T1, and RG2012N-2943-W-T5 are direct Susumu alternatives maintaining identical electrical and mechanical specifications while offering improved tolerance performance. All three parts are active products with established supply chains. The RG2012N-2943-W-T5 provides the highest inventory availability (1009 pieces) and represents the optimal choice for designs requiring ±0.05% tolerance with maintained power rating and temperature range.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805294KBYEA from Vishay Dale provides an alternative source for 294 kOhms 0805 thin film resistors with AEC-Q200 qualification. This part offers enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The ±0.1% tolerance meets the original specification requirement. This option is suitable for applications where higher thermal margin or increased power dissipation capability is beneficial.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity rating. No design re-qualification is required for substitution within this group.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2943-W-T5 directly replace RG2012N-2943-C-T5?

A: Yes. Both parts share identical resistance (294 kOhms), package (0805), power rating (0.125W), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The RG2012N-2943-W-T5 provides tighter tolerance (±0.05% versus ±0.25%), which is a performance improvement with no compatibility issues.

Q: What is the difference between RG2012N-2943-W-T1 and RG2012N-2943-W-T5?

A: Both parts are identical in electrical and mechanical specifications. The suffix designates different tape and reel configurations (T1 versus T5). Selection depends on packaging and handling requirements for manufacturing processes.

Q: Is TNPW0805294KBYEA suitable for the same applications as RG2012N-2943-C-T5?

A: Yes, with the following considerations: TNPW0805294KBYEA provides higher power rating (0.26W) and extended temperature range (-55°C ~ 175°C). These are performance enhancements. The ±0.1% tolerance meets the original ±0.25% specification. Cross-manufacturer substitution is valid for applications where Vishay Dale supply chain is preferred.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification identical to the original RG2012N-2943-C-T5.

Q: What is the significance of the obsolete status of RG2012N-2943-C-T5?

A: Obsolete status indicates the part is no longer manufactured by Susumu. The listed substitute parts (RG2012N-2943-B-T5, RG2012N-2943-W-T1, RG2012N-2943-W-T5) are active products with ongoing production and supply availability.

Q: Can tolerance be relaxed when substituting?

A: No. Tolerance specifications must be maintained at the original level or improved (tighter). Substitutes with ±0.1% or ±0.05% tolerance are acceptable replacements for ±0.25% requirement. Substitutes with looser tolerance are not acceptable.

Q: Are there package size differences between substitute parts?

A: No. All substitute parts use identical 0805 (2012 Metric) package with matching physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.020" / 0.50mm), with the exception of TNPW0805294KBYEA which has maximum seated height of 0.022" (0.55mm). This minor height difference does not affect PCB layout compatibility.
