Parameter Comparison

Engineering Selection Recommendations

Both the RCS2012F3094CS and CRCW08053M09FKEA are active production components with full RoHS3 compliance and REACH unaffected status. The primary distinction between these parts is the additional automotive AEC-Q200 qualification of the Vishay Dale CRCW08053M09FKEA, which certifies the component for automotive-grade reliability and environmental stress testing. The Samsung RCS2012F3094CS features anti-sulfur and moisture-resistant construction, while the Vishay part carries automotive-specific qualification.

Selection between these equivalents should be based on application requirements: the Vishay CRCW08053M09FKEA is suitable for automotive and mission-critical applications requiring AEC-Q200 certification, while the Samsung RCS2012F3094CS is appropriate for general industrial and consumer applications where anti-sulfur protection is prioritized. Both components are electrically and mechanically interchangeable within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08053M09FKEA directly replace the RCS2012F3094CS in existing designs?

A: Yes. Both components share identical electrical specifications (3.09 MOhms ±1%, 0.125W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical package format (0805 / 2012 Metric). The physical dimensions and termination count are equivalent, enabling direct PCB-level substitution.

Q: What is the significance of the height difference between these parts?

A: The RCS2012F3094CS has a maximum seated height of 0.026" (0.66mm), while the CRCW08053M09FKEA measures 0.020" (0.50mm). This 0.006" (0.16mm) difference is within typical PCB assembly tolerances and does not affect functional performance or standard reflow soldering processes.

Q: Why does the Vishay part carry AEC-Q200 certification while the Samsung part does not?

A: AEC-Q200 is an automotive industry qualification standard. The Vishay CRCW08053M09FKEA is specifically qualified for automotive applications, while the Samsung RCS2012F3094CS is designed for general industrial use. Both parts meet identical electrical and environmental specifications; the AEC-Q200 designation indicates additional automotive-specific testing and reliability documentation.

Q: Are there packaging differences between these substitute parts?

A: The RCS2012F3094CS is supplied in Tape & Reel (TR) packaging, while the CRCW08053M09FKEA is available in Cut Tape (CT) and Digi-Reel® formats. Both packaging types are standard for 0805 components and do not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RCS2012F3094CS and CRCW08053M09FKEA are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and share the same HTSUS code (8533.21.0030). Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
