RC2012F1911CS Equivalent & Substitute Parts

Part Overview

The RC2012F1911CS is a 1.91 kOhms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This thick film, moisture-resistant resistor operates across a temperature range of -55°C to 155°C and is classified as Active product status. Substitute parts are identified when original inventory becomes unavailable, when alternative manufacturers offer equivalent electrical and mechanical specifications, or when design requirements necessitate components with enhanced certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F1911CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.91 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• Composition: Thick Film
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in seated height and packaging format (Tape & Reel versus Cut Tape) do not affect electrical or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-071K91L (YAGEO): This substitute provides direct electrical and mechanical equivalence to the RC2012F1911CS. Both components share identical resistance, tolerance, power rating, and temperature specifications. The YAGEO part is available in higher inventory volume (54,280 pieces) and maintains the same RoHS3 compliance and MSL rating. The seated height of 0.024" (0.60mm) is within acceptable PCB assembly tolerances for 0805 package components.

CRCW08051K91FKEA (Vishay Dale): This substitute meets all core electrical and mechanical requirements and includes AEC-Q200 automotive qualification. The lower seated height of 0.020" (0.50mm) provides additional clearance margin in space-constrained applications. This component is suitable for designs requiring automotive-grade reliability certification.

ERJ-6ENF1911V (Panasonic): This substitute provides full electrical equivalence and includes AEC-Q200 automotive qualification. Available in the highest inventory volume (102,024 pieces), this component is supplied in Cut Tape and Digi-Reel packaging formats. The seated height of 0.028" (0.70mm) remains within standard PCB assembly specifications for 0805 components.

All three substitute parts maintain Active product status and comply with ROHS3 and REACH requirements, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071K91L be used as a direct replacement for RC2012F1911CS?

A: Yes. Both components share identical electrical specifications (1.91 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package format (0805), and compliance ratings (ROHS3, MSL 1). The minor difference in seated height (0.024" versus 0.026") does not affect PCB assembly or circuit performance.

Q: What is the difference between the Samsung and YAGEO versions?

A: The RC2012F1911CS (Samsung) and RC0805FR-071K91L (YAGEO) are electrically and mechanically identical. The primary differences are manufacturer, series designation (RC versus RC_L), and seated height tolerance (0.026" maximum versus 0.024" maximum). Both are suitable for general industrial applications.

Q: When should I select the Vishay Dale or Panasonic parts instead of YAGEO?

A: Select CRCW08051K91FKEA (Vishay Dale) or ERJ-6ENF1911V (Panasonic) when your application requires AEC-Q200 automotive qualification. These parts are certified for automotive-grade reliability and are appropriate for automotive, industrial control, and mission-critical applications. The RC2012F1911CS and RC0805FR-071K91L do not carry automotive certification.

Q: Are there packaging format differences between these substitutes?

A: The RC2012F1911CS, RC0805FR-071K91L, and CRCW08051K91FKEA are supplied in Tape & Reel (TR) format. The ERJ-6ENF1911V is supplied in Cut Tape (CT) and Digi-Reel format. Packaging format does not affect component performance but may influence procurement and assembly processes.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All four components carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly. No baking or special moisture control procedures are required.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts are mechanically compatible with the 0805 package footprint and have seated heights within standard PCB assembly tolerances. They can be used interchangeably without PCB redesign or assembly process modification.
