RCS2012F2052CS Equivalent & Substitute Parts

Part Overview

The RCS2012F2052CS is a 20.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part features anti-sulfur and moisture-resistant construction with unlimited moisture sensitivity level (MSL 1). The RCS2012F2052CS maintains Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when applications require alternative sourcing, inventory management, or specific certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F2052CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 20.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Termination Count: 2 (exact match required)
• Compliance: RoHS3 Compliant, REACH Unaffected, MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Variations in physical dimensions (height-seated maximum) and additional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution when the core electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F2052CS, CRCW080520K5FKEA, ERJ-6ENF2052V, and RC0805FR-0720K5L—are electrically and mechanically equivalent for direct substitution in applications requiring a 20.5 kOhms ±1% 0805 thick film chip resistor rated at 0.125W.

RCS2012F2052CS (Samsung Electro-Mechanics): Primary part with anti-sulfur and moisture-resistant features. Active product status with unlimited MSL rating. Suitable for general industrial and consumer applications.

CRCW080520K5FKEA (Vishay Dale): Automotive AEC-Q200 qualified alternative. Identical electrical specifications with reduced maximum seated height (0.020" vs. 0.026"). Appropriate for automotive and mission-critical applications requiring AEC-Q200 certification.

ERJ-6ENF2052V (Panasonic Electronic Components): Automotive AEC-Q200 qualified alternative. Identical electrical specifications with maximum seated height of 0.028". Highest inventory availability among substitutes. Suitable for automotive and mission-critical applications requiring AEC-Q200 certification.

RC0805FR-0720K5L (YAGEO): Moisture-resistant thick film construction. Identical electrical specifications with maximum seated height of 0.024". Active product status. Suitable for general industrial and consumer applications.

Selection between these parts depends on application requirements for automotive certification (AEC-Q200) and physical space constraints related to component height. All parts maintain RoHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can CRCW080520K5FKEA replace RCS2012F2052CS in non-automotive applications?

A: Yes. The CRCW080520K5FKEA meets all electrical and mechanical requirements for direct substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. The reduced maximum seated height (0.020" vs. 0.026") may provide design advantages in space-constrained layouts.

Q: What is the significance of the height-seated maximum variation among these parts?

A: Height-seated maximum values (ranging from 0.020" to 0.028") indicate the maximum vertical dimension of the component when mounted on a PCB. These variations are within the 0805 package specification and do not affect electrical performance. Selection should consider PCB clearance requirements and assembly process constraints.

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

A: Yes. All four parts—RCS2012F2052CS, CRCW080520K5FKEA, ERJ-6ENF2052V, and RC0805FR-0720K5L—are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring equivalent thermal performance.

Q: What is the difference between anti-sulfur and automotive AEC-Q200 features?

A: Anti-sulfur construction (featured in RCS2012F2052CS and RC0805FR-0720K5L) provides protection against sulfur-containing environmental contaminants. Automotive AEC-Q200 qualification (featured in CRCW080520K5FKEA and ERJ-6ENF2052V) indicates compliance with automotive industry reliability and quality standards. These are distinct features; AEC-Q200 parts do not necessarily include anti-sulfur treatment, and vice versa.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts carry RoHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for electronic components.

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

A: Yes. All parts are electrically and mechanically equivalent within the 0805 package specification. Interchangeability is determined by identical resistance value (20.5 kOhms), tolerance (±1%), power rating (0.125W), and operating temperature range (-55°C to 155°C). Physical height variations do not preclude interchangeability provided PCB layout accommodates the maximum seated height of the selected part.
