RCS2012F515CS Equivalent & Substitute Parts

Part Overview

The RCS2012F515CS is a 5.1 MOhm ±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 is designed for general-purpose electronic applications requiring high-value resistive elements. The part is currently in active production status with anti-sulfur and moisture-resistant construction. Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and environmental ratings to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F515CS are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 5.1 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 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 core electrical and mechanical specifications. Variations in packaging format (Tape & Reel versus Cut Tape) and minor dimensional differences in seated height do not affect functional equivalence. Automotive-grade certifications (AEC-Q200) represent enhanced qualification but do not preclude substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed in the parameter comparison table are functionally equivalent for applications requiring a 5.1 MOhm ±1% 0.125W 0805 thick film resistor. Selection among these alternatives is determined by availability, packaging preference, and application-specific requirements.

RC2012F515CS (Samsung Electro-Mechanics): Direct Samsung alternative with identical electrical specifications and similar packaging. Differs only in packaging format (Cut Tape versus Tape & Reel) and negligible seated height variation (0.65mm versus 0.66mm).

CRCW08055M10FKEA (Vishay Dale): Qualified to AEC-Q200 automotive standard. Suitable for applications requiring automotive-grade reliability. Seated height is 0.020" (0.50mm), which is lower than the main part. All electrical parameters remain equivalent.

RC0805FR-075M1L (YAGEO): Available in both Cut Tape and Digi-Reel® packaging formats. Seated height is 0.024" (0.60mm). Highest inventory availability among substitute options.

All parts carry ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical operating temperature ranges. Selection should be based on procurement lead time, cost, packaging requirements, and existing supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can RC2012F515CS be used as a direct replacement for RCS2012F515CS?

A: Yes. Both parts are manufactured by Samsung Electro-Mechanics with identical electrical specifications (5.1 MOhm ±1%, 0.125W, ±100ppm/°C). The primary difference is packaging format: RCS2012F515CS is supplied in Tape & Reel format while RC2012F515CS is supplied in Cut Tape format. Seated height differs by 0.01mm (0.66mm versus 0.65mm), which is negligible for standard PCB assembly.

Q: Is CRCW08055M10FKEA suitable for non-automotive applications?

A: Yes. AEC-Q200 automotive qualification represents enhanced reliability testing and does not restrict use in non-automotive circuits. The part meets all electrical and environmental specifications required for general-purpose applications.

Q: What is the significance of the seated height differences among substitute parts?

A: Seated height variations (0.50mm to 0.66mm) are within standard PCB assembly tolerances and do not affect functional performance. These differences may be relevant only for applications with strict height constraints or high-density packaging requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, ensuring compatibility with environmental regulations and industry standards.

Q: What packaging formats are available among the substitute parts?

A: RCS2012F515CS and CRCW08055M10FKEA are supplied in Tape & Reel (TR) format. RC2012F515CS is supplied in Cut Tape (CT) format. RC0805FR-075M1L is available in both Cut Tape (CT) and Digi-Reel® formats. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
