Parameter Comparison

Engineering Selection Recommendations

The CRCW12065M23FKEA (Vishay Dale) is a direct functional equivalent to the RCS3216F5234CS (Samsung Electro-Mechanics). Both components satisfy identical electrical specifications, mechanical dimensions, and compliance requirements.

Selection Basis:

Both parts are classified as Active product status with ROHS3 compliance and REACH Unaffected designation. The electrical parameters—5.23 MOhms resistance, ±1% tolerance, 0.25W power rating, and ±100ppm/°C temperature coefficient—are identical across both components. The 1206 (3216 Metric) package ensures mechanical compatibility with existing PCB layouts and assembly processes.

The CRCW12065M23FKEA includes Automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The maximum seated height difference of 0.002" (0.06mm) between the two parts is within standard PCB assembly tolerances and does not impact functional performance or board-level compatibility.

Selection between these parts depends on supply chain availability, cost considerations, and application-specific requirements for automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the CRCW12065M23FKEA replace the RCS3216F5234CS in existing designs?

A: Yes. Both components share identical electrical specifications (5.23 MOhms, ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and mechanical dimensions (1206 package, 0.126" x 0.063"). Direct substitution is supported without circuit modification.

Q: What is the significance of the AEC-Q200 rating on the CRCW12065M23FKEA?

A: AEC-Q200 is an automotive qualification standard indicating the component meets reliability and performance requirements for automotive applications. This certification is an additional feature of the Vishay Dale part and does not affect compatibility with non-automotive applications.

Q: Are there differences in package dimensions between these parts?

A: Both parts use the 1206 (3216 Metric) package with identical length and width (0.126" x 0.063"). The maximum seated height differs by 0.002" (0.06mm), which is within standard PCB assembly tolerances and does not impact board-level compatibility or functionality.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the RCS3216F5234CS and CRCW12065M23FKEA are ROHS3 compliant, REACH Unaffected, classified as EAR99, and carry HTSUS code 8533.21.0030. Both have Moisture Sensitivity Level 1 (Unlimited).

Q: What factors should determine which part to select?

A: Selection should be based on supply chain availability, cost, lead time, and application-specific requirements. If automotive qualification is required, the CRCW12065M23FKEA is the appropriate choice. For general industrial applications, either part is functionally equivalent.
