Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-1911-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 1.91 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: minimum 0.125W (1/8W)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• Anti-sulfur coating: Required
• RoHS3 compliance: Required

Substitution Criteria: Substitute parts must maintain identical resistance value and package configuration. Tolerance specifications may be tighter (lower tolerance values) without affecting compatibility. Temperature coefficient may be equal or superior (lower absolute value). Operating temperature range must encompass or exceed the original specification. Power rating may be equal or higher. All substitute parts must retain AEC-Q200 automotive qualification and anti-sulfur features.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N and RG2012V series parts provide direct electrical and mechanical compatibility with the obsolete RG2012N-1911-C-T5. All substitute parts maintain the 1.91 kOhms resistance value, 0805 package configuration, and AEC-Q200 automotive qualification.

RG2012N Series (±10ppm/°C Temperature Coefficient):

• RG2012N-1911-B-T5: Tighter tolerance (±0.1%) with active product status
• RG2012N-1911-W-T1 and RG2012N-1911-W-T5: Superior tolerance (±0.05%) with active product status

RG2012V Series (±5ppm/°C Temperature Coefficient):

• RG2012V-1911-B-T5: ±0.1% tolerance with improved temperature stability
• RG2012V-1911-P-T1: Highest precision (±0.02%) with superior temperature coefficient
• RG2012V-1911-W-T1 and RG2012V-1911-W-T5: ±0.05% tolerance with improved temperature stability

Cross-Manufacturer Alternative:

TNPW08051K91BYEA (Vishay Dale TNPW e3 series) provides equivalent electrical performance with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C). This part maintains AEC-Q200 qualification and anti-sulfur coating with moisture-resistant characteristics.

Selection Basis: All substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. Selection should be based on tolerance requirements, temperature coefficient specifications, and power dissipation margin requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-1911-B-T5 directly replace RG2012N-1911-C-T5?

A: Yes. Both parts share identical resistance (1.91 kOhms), package (0805), power rating (0.125W), and temperature coefficient (±10ppm/°C). The substitute has tighter tolerance (±0.1% versus ±0.25%) and active product status, making it a direct replacement with improved performance characteristics.

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

A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C while RG2012V series has ±5ppm/°C. Both series maintain identical resistance, package, power rating, and AEC-Q200 qualification. RG2012V provides superior temperature stability for precision applications.

Q: Is the Vishay Dale TNPW08051K91BYEA compatible with the original part?

A: Yes, with considerations. The part maintains 1.91 kOhms resistance, 0805 package, AEC-Q200 qualification, and anti-sulfur coating. The higher power rating (0.26W) and extended temperature range (-55°C ~ 175°C) provide additional design margin. Physical dimensions are compatible with identical length and width (2.00mm x 1.25mm) and similar height (0.55mm maximum versus 0.50mm).

Q: Does tolerance affect substitution compatibility?

A: Tighter tolerance specifications (lower percentage values) are compatible substitutes. A ±0.1% part can replace a ±0.25% specification. Conversely, looser tolerance parts are not suitable substitutes for tighter tolerance requirements.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, maintaining consistency with standard surface mount assembly processes.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift with temperature change. RG2012V series (±5ppm/°C) exhibits half the drift rate of RG2012N series (±10ppm/°C). For applications requiring stable resistance across the operating temperature range, RG2012V series provides superior performance.

Q: Can parts with different tolerance specifications be mixed in the same assembly?

A: Substitution decisions should be based on circuit design requirements. Parts with tighter tolerances can replace looser tolerance specifications. Mixed tolerance parts in the same circuit should be evaluated against the specific tolerance stack-up requirements of the application.
