RCS2012F2740CS Equivalent & Substitute Parts

Part Overview

The RCS2012F2740CS is a 274 Ohms ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is actively produced and widely used in general-purpose electronic applications requiring precision resistive elements with anti-sulfur and moisture-resistant properties. Substitute parts are identified for applications requiring alternative sourcing, extended lead times, or specific certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F2740CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 274 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these electrical and mechanical specifications. Differences in physical height and feature sets (such as automotive AEC-Q200 certification) do not prevent functional substitution but may be relevant for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All five components listed are active products with ROHS3 compliance and identical electrical specifications. Selection between the RCS2012F2740CS and its substitutes is based on the following factors:

General-Purpose Applications: The RCS2012F2740CS (Samsung) and RC0805FR-07274RL (YAGEO) are suitable for applications without automotive qualification requirements. Both provide anti-sulfur or moisture-resistant features and maintain identical electrical performance.

Automotive Applications: The CRCW0805274RFKEA (Vishay Dale), ERJ-6ENF2740V (Panasonic), and RMCF0805FT274R (Stackpole) carry AEC-Q200 automotive qualification. These parts are appropriate for automotive-grade circuit designs where component reliability standards are mandated.

Physical Constraints: The CRCW0805274RFKEA offers the lowest maximum seated height at 0.020" (0.50mm), which may be advantageous in space-constrained designs. The ERJ-6ENF2740V has the highest maximum seated height at 0.028" (0.70mm). All other variants fall within intermediate ranges and are mechanically compatible with standard 0805 footprints.

Availability and Sourcing: Inventory levels vary across manufacturers. Selection may be influenced by supplier availability, lead times, and procurement agreements.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805274RFKEA replace RCS2012F2740CS in a non-automotive application?

A: Yes. The CRCW0805274RFKEA meets all electrical and mechanical specifications required for the RCS2012F2740CS. The automotive AEC-Q200 certification is an additional qualification that does not prevent use in general-purpose applications. Physical height difference (0.020" vs 0.026") is within standard 0805 package tolerance and compatible with typical PCB footprints.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The temperature coefficient indicates the fractional change in resistance per degree Celsius. All listed parts share identical ±100ppm/°C specifications, ensuring equivalent thermal stability across the operating temperature range of -55°C to 155°C.

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

A: Yes. All parts listed are supplied in Tape & Reel format, suitable for automated assembly processes.

Q: Does the anti-sulfur feature of the RCS2012F2740CS provide an advantage over other substitutes?

A: The anti-sulfur feature of the RCS2012F2740CS is specific to Samsung's manufacturing process. The YAGEO RC0805FR-07274RL also includes moisture-resistant properties. The automotive-qualified parts (Vishay Dale, Panasonic, Stackpole) do not explicitly list anti-sulfur features in the provided specifications. Selection should be based on application environment requirements.

Q: Can ERJ-6ENF2740V be used as a direct drop-in replacement for RCS2012F2740CS?

A: Yes. The ERJ-6ENF2740V is electrically and mechanically equivalent. The maximum seated height difference (0.028" vs 0.026") is negligible for standard PCB assembly and does not affect functional compatibility.

Q: What does ROHS3 compliance mean for these components?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, restricting the use of specific hazardous materials. All listed parts meet this environmental standard.

Q: Is MSL 1 (Unlimited) rating important for component selection?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations and does not require special handling or storage conditions. All listed parts share this rating, eliminating moisture sensitivity as a differentiation factor.
