RC2012F3091CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F3091CS is a 3.09 kOhms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This thick film resistor operates across -55°C to 155°C with moisture resistant characteristics and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit applications without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F3091CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 3.09 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package / Case: 0805 (2012 Metric)
• Supplier device package: 0805
• Number of terminations: 2

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), height-seated maximum dimensions, and additional certifications (such as AEC-Q200 automotive qualification) do not prevent substitution when the core electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—RC0805FR-073K09L (YAGEO), CRCW08053K09FKEA (Vishay Dale), and ERJ-6ENF3091V (Panasonic)—are functionally equivalent to the RC2012F3091CS and maintain Active product status.

YAGEO RC0805FR-073K09L provides direct substitution with identical electrical and mechanical specifications. This part is available in high inventory volume (59,593 pcs) and maintains standard Tape & Reel packaging.

Vishay Dale CRCW08053K09FKEA offers substitution with the additional qualification of AEC-Q200 automotive certification. This part is suitable for applications requiring automotive-grade reliability and is available in high inventory volume (99,501 pcs).

Panasonic ERJ-6ENF3091V provides substitution with AEC-Q200 automotive certification and is available in Cut Tape and Digi-Reel packaging formats. Inventory availability is 22,401 pcs.

Selection among these substitutes depends on packaging format requirements, inventory availability, and whether automotive-grade qualification (AEC-Q200) is specified for the application. All parts comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-073K09L replace RC2012F3091CS directly?

A: Yes. RC0805FR-073K09L meets all critical electrical parameters (3.09 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical specifications (0805 package, 2.00mm x 1.25mm), and compliance certifications (ROHS3, MSL 1, REACH Unaffected) required for direct substitution.

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

A: Both parts share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, package format, and compliance status. The primary difference is manufacturer identity and height-seated maximum dimension (0.66mm for Samsung vs. 0.60mm for YAGEO), which does not affect electrical performance or circuit compatibility.

Q: Are the Vishay Dale and Panasonic parts suitable for non-automotive applications?

A: Yes. CRCW08053K09FKEA and ERJ-6ENF3091V meet all electrical and mechanical specifications for the RC2012F3091CS. The AEC-Q200 automotive certification is an additional qualification that does not restrict use in standard industrial or consumer applications.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel vs. Cut Tape) affects procurement and handling but does not affect electrical or mechanical compatibility. All identified substitutes are available in standard industry packaging formats suitable for automated assembly processes.

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

A: Yes. All substitute parts conform to the 0805 (2012 Metric) package specification with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), enabling direct PCB placement without layout modification.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture bake requirements prior to soldering. All identified parts carry this classification, eliminating moisture management constraints during storage and assembly.
