RCS2012F2801CS Equivalent & Substitute Parts

Part Overview

The RCS2012F2801CS is a 2.8 kOhms ±1% 0.125W (1/8W) chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties with an operating temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified for applications requiring alternative sourcing, inventory management, or specific feature requirements such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F2801CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 2.8 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 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:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are grouped by additional features: automotive AEC-Q200 qualification (CRCW08052K80FKEA, ERJ-6ENF2801V, RMCF0805FT2K80) and moisture-resistant composition without automotive qualification (RC0805FR-072K8L).

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and meet the core electrical and mechanical specifications of the RCS2012F2801CS. Selection among substitutes is based on application-specific requirements:

For general-purpose applications without automotive requirements:

• RC0805FR-072K8L (YAGEO) provides direct functional equivalence with moisture-resistant composition and is available in Cut Tape and Digi-Reel® packaging options.

For automotive applications requiring AEC-Q200 qualification:

• CRCW08052K80FKEA (Vishay Dale) offers automotive-grade reliability with the lowest seated height (0.020").
• ERJ-6ENF2801V (Panasonic Electronic Components) provides automotive AEC-Q200 qualification with the highest seated height (0.028").
• RMCF0805FT2K80 (Stackpole Electronics Inc) delivers automotive AEC-Q200 qualification with seated height (0.026") matching the original part.

For inventory and sourcing flexibility:

• RMCF0805FT2K80 (Stackpole) offers the largest available inventory (188,659 pcs).
• ERJ-6ENF2801V (Panasonic) provides the second-largest inventory (68,992 pcs).

All substitute parts maintain identical electrical performance, temperature stability, and compliance certifications as the RCS2012F2801CS.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K80FKEA replace RCS2012F2801CS in any application?

A: Yes. CRCW08052K80FKEA meets all electrical and mechanical specifications of RCS2012F2801CS. The primary difference is automotive AEC-Q200 qualification, which adds reliability assurance for automotive environments. The seated height is 0.020" compared to 0.026" for the original part; this difference is within typical PCB design tolerances for 0805 packages.

Q: What is the difference between automotive AEC-Q200 qualified parts and non-qualified parts?

A: Automotive AEC-Q200 qualification indicates the part has undergone additional reliability testing and qualification for automotive applications. CRCW08052K80FKEA, ERJ-6ENF2801V, and RMCF0805FT2K80 carry this qualification. RCS2012F2801CS and RC0805FR-072K8L do not. For non-automotive applications, AEC-Q200 qualification is not required.

Q: Are there packaging differences among the substitute parts?

A: Yes. RC0805FR-072K8L is available in Cut Tape (CT) and Digi-Reel® packaging, while CRCW08052K80FKEA, ERJ-6ENF2801V, and RMCF0805FT2K80 are supplied in Tape & Reel (TR) packaging. The original RCS2012F2801CS is also Tape & Reel. Packaging selection depends on assembly equipment and production volume requirements.

Q: Do all substitute parts have the same physical dimensions?

A: All substitute parts share the same package type (0805 / 2012 Metric) and external dimensions (0.079" L x 0.049" W). Seated height varies slightly: RCS2012F2801CS (0.026"), CRCW08052K80FKEA (0.020"), ERJ-6ENF2801V (0.028"), RC0805FR-072K8L (0.024"), and RMCF0805FT2K80 (0.026"). These variations are within standard 0805 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute part has the best inventory availability?

A: RMCF0805FT2K80 (Stackpole Electronics Inc) has the largest inventory at 188,659 pcs. ERJ-6ENF2801V (Panasonic) follows with 68,992 pcs. CRCW08052K80FKEA (Vishay Dale) has 20,915 pcs, and RC0805FR-072K8L (YAGEO) has 23,200 pcs.

Q: Can I use ERJ-6ENF2801V as a direct drop-in replacement for RCS2012F2801CS?

A: Yes. ERJ-6ENF2801V is electrically and mechanically equivalent to RCS2012F2801CS. The seated height is 0.028" compared to 0.026" for the original part. This 0.002" difference is within standard PCB design clearances for 0805 components and does not prevent direct substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (CRCW08052K80FKEA, ERJ-6ENF2801V, RC0805FR-072K8L, and RMCF0805FT2K80) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance profile of RCS2012F2801CS.
