Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-2940-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 294 Ohms
• Package type: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter (lower) than ±0.25%
• Temperature coefficient: Can be equal to or lower than ±10ppm/°C
• Product status: Active status preferred over obsolete

All substitute parts listed maintain identical mechanical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and electrical ratings. Substitutes with improved tolerance or temperature coefficient specifications provide enhanced performance while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Tolerance ±0.25% or Tighter):

All listed substitute parts are qualified for direct substitution in applications where the RG2012N-2940-C-T5 was originally specified. The obsolete status of the main part necessitates transition to active alternatives.

Selection by Application Requirements:

1. Standard Tolerance Applications (±0.25% acceptable): RG2012N-2940-B-T5 provides the minimum tolerance improvement (±0.1%) while maintaining the ±10ppm/°C temperature coefficient of the original part. This option is suitable for general-purpose automotive circuits.

2. Precision Tolerance Applications (±0.05% required): RG2012N-2940-W-T5 and RG2012N-2940-W-T1 both offer ±0.05% tolerance with ±10ppm/°C temperature coefficient. These parts maintain identical thermal performance to the original specification.

3. High-Precision Applications (±0.05% or better with improved temperature stability): RG2012V-2940-W-T5 and RG2012V-2940-W-T1 provide ±0.05% tolerance with superior ±5ppm/°C temperature coefficient, representing a 50% improvement in thermal stability.

4. Ultra-Precision Applications (±0.02% required): RG2012V-2940-P-T1 delivers the tightest tolerance specification (±0.02%) combined with ±5ppm/°C temperature coefficient for applications demanding maximum accuracy.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Mechanical compatibility is assured across all options.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2940-C-T5 be replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain identical resistance value (294 Ohms), package type (0805), power rating (0.125W), composition (thin film), and automotive qualification (AEC-Q200). Substitutes with tighter tolerance or lower temperature coefficient specifications are fully compatible and provide equal or superior performance.

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

A: The RG2012V series components feature a ±5ppm/°C temperature coefficient compared to ±10ppm/°C in the RG2012N series. This represents improved thermal stability. Both series are AEC-Q200 qualified and suitable for automotive applications.

Q: Are there packaging differences between substitute options?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original RG2012N-2940-C-T5 packaging specification was not explicitly defined in the provided data. The 0805 (2012 Metric) package dimensions remain constant across all options: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm).

Q: Which substitute part should be selected for cost-sensitive applications?

A: Selection should be based on tolerance and temperature coefficient requirements rather than cost considerations. RG2012N-2940-B-T5 provides the minimum performance improvement (±0.1% tolerance) over the original specification while maintaining ±10ppm/°C temperature coefficient.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original RG2012N-2940-C-T5.

Q: What is the significance of the tolerance and temperature coefficient parameters in substitution?

A: Tolerance defines the acceptable resistance value deviation from the nominal 294 Ohms specification. Temperature coefficient defines how resistance changes with temperature variation. Substitute parts with equal or tighter (lower) tolerance and equal or lower temperature coefficient values maintain or exceed the original part's performance specifications and are fully interchangeable.
