RCS2012F2214CS Equivalent & Substitute Parts

Part Overview

The RCS2012F2214CS is a 2.21 MOhms ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with RoHS3 compliance. The part is currently active in production with 698 pieces in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F2214CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 2.21 MOhms
• 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)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel versus Cut Tape), seated height tolerances, and specific feature sets (anti-sulfur versus automotive AEC-Q200 qualification) do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with full RoHS3 and REACH compliance. Selection between the RCS2012F2214CS and its substitutes is based on availability, packaging preference, and application-specific requirements:

CRCW08052M21FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification. Selection of this part is appropriate for automotive applications or when automotive-grade reliability documentation is required. Seated height is 0.020" (0.50mm), the lowest among the three options, which may be advantageous in space-constrained designs.

RC0805FR-072M21L (YAGEO): This substitute is available in Cut Tape and Digi-Reel packaging formats. Seated height is 0.024" (0.60mm). This part is suitable for applications where packaging flexibility or specific supplier relationships favor YAGEO components.

RCS2012F2214CS (Samsung Electro-Mechanics): The primary part features anti-sulfur properties in addition to moisture resistance. Seated height is 0.026" (0.66mm). This specification is appropriate for environments with elevated sulfur exposure or when Samsung-specific supply chain requirements apply.

All parts share identical electrical specifications and thermal performance characteristics. Seated height variations are within typical PCB assembly tolerances and do not affect functional performance in standard applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052M21FKEA replace RCS2012F2214CS in non-automotive applications?

A: Yes. The CRCW08052M21FKEA 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. All core parameters—resistance, tolerance, power rating, temperature range, and package dimensions—are identical.

Q: What is the significance of the seated height differences (0.026", 0.024", 0.020")?

A: Seated height variations reflect manufacturing tolerances across different manufacturers. These differences are within standard PCB assembly specifications and do not affect component functionality or circuit performance. Selection based on seated height is only necessary in applications with extremely tight vertical clearance constraints.

Q: Are the anti-sulfur properties of the RCS2012F2214CS critical for substitution?

A: Anti-sulfur properties are application-dependent. If the original design specifies anti-sulfur characteristics due to environmental exposure, the RCS2012F2214CS should be retained. For standard indoor or controlled environments, the moisture-resistant properties of RC0805FR-072M21L and CRCW08052M21FKEA are functionally equivalent.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical performance is identical regardless of packaging type. Selection between Tape & Reel and Cut Tape is based on manufacturing process requirements and inventory management practices.

Q: Are all three parts suitable for high-temperature applications at 155°C?

A: Yes. All three parts are rated for continuous operation at -55°C to 155°C with ±100ppm/°C temperature coefficient. Performance is equivalent across the full operating temperature range.

Q: What compliance certifications apply to all substitute parts?

A: All parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
